Duke Libraries has a large collection of analog videotapes, in several different formats. One of the most common in our archives is 3/4″ videotape, also called “U-matic” (shown above). Invented by Sony in 1969, U-matic was the first videotape to be housed inside a plastic cassette for portability. Before U-matic, videotape was recorded on very large reels in the 2″ format known as Quadruplex which required heavy recording and playback machines the size of household refrigerators. U-matic got its name from the shape of the tape path as it wraps around the video head drum, which looks like the letter U.
The format was officially released in 1971, and soon became popular with television stations, when the portable Sony VO-3800 video deck was released in 1974. The VO-3800 enabled TV crews to record directly to U-matic videotape at breaking news events, which previously had to be shot with 16mm film. The news content was now immediately available for broadcast, as opposed to film, which had to wait for processing in a darkroom. And the compact videocassettes could easily and quickly be transported to the TV station.
In the 1970’s, movie studios also used U-matic tapes to easily transport filmed scenes or “dailies,” such as the first rough cut of “Apocalypse Now.” In 1976, the high-band BVU (Broadcast Video U-matic) version of 3/4″ videotape, with better color reproduction and lower noise levels, replaced the previous “lo-band” version.
The U-matic format remained popular at TV stations throughout the 1980’s, but was soon replaced by Sony’s 1/2″ Betacam SP format. The BVU-900 series was the last U-matic product line made by Sony, and Duke Libraries’ Digital Production Center uses two BVU-950s for NTSC tapes, as well as a VO-9800P for tapes in PAL format. A U-matic videotape player in good working order is now an obsolete collector’s item, so they can be hard to find, and expensive to purchase.
Unfortunately, most U-matic tapes have not aged well. After decades in storage, many of the videotapes in our collection now have sticky-shed syndrome, a condition in which the oxide that holds the visual content is literally flaking off the polyester tape base, and is moist and gummy in texture. When a videotape has sticky-shed, not only will it not play correctly, the residue can also clog up the tape heads in the U-matic playback deck, then transfer the contaminant to other tapes played afterwards in the same deck.
To combat this, we always bake (dehumidify) our U-matic videotapes in a scientific oven at 52 celsius (125 fahrenheit) for at least 10 hours. Then we run each tape through a specialized tape-cleaning machine, which fast-forwards and rewinds each tape, while using a burnishing blade to wipe off any built-up residue. We also clean the video heads inside our U-matic decks before each playback, using denatured alcohol.
Most of the time, these procedures make the U-matic tape playable, and we are able to digitize them, which rescues the content from the videotapes, before the magnetic tape ages and degrades any further. While the U-matic tapes are nearing the end of their life-span, the digital surrogates will potentially last for centuries to come, and will be accessible online through our Duke Digital Repository, from anywhere in the world.
One of the highlights of the Association of Moving Image Archivists’ annual conference is “Archival Screening Night,” where members of the AMIA community showcase recently-discovered and newly-restored film and video footage. The event usually takes place in a historic movie theater, with skilled projectionists that are able to present the film materials in their original format, on the big screen. At the most recent AMIA conference, in Portland, Oregon, there was a wide array of impressive material presented, but one film in particular left the audience speechless, and is a wonderful example of how archivists can unearth treasures that can alter our perspective on human history, and humanity itself.
The film, “Something Good – Negro Kiss” was made in 1898. It’s silent, black & white, and is less than a minute long. But it’s groundbreaking, in that it shows the earliest known depiction of an African-American couple kissing, and stands in opposition to the racist, minstrel-show portrayals of black people so common in the early days of American filmmaking. The couple embrace, kiss, and sway back and forth in a playful, spontaneous dance that comes across as genuine and heartwarming. Although it may not have been intentional, the short film seems to be free of negative racial stereotypes. You can watch it here:
The film is likely an homage to “The Kiss” (also known as the May Irwin Kiss), a film made in 1896, with a white couple kissing. It was one of the first films ever shown commercially, and is the very first kiss on film. Even though the couple was white, and the kissing is remarkably tame by today’s standards, it created a lot of controversy at the time, because kissing in public was prohibited by law. The Catholic church and newspaper editorials denounced “The Kiss” and called for censorship and prosecution. Although there is no documented history yet about the public reaction to “Something Good – Negro Kiss,” one can only imagine the shock and scandal it must have caused, showing an African-American couple kissing each other, only two years later.
When Duke students tour the Digital Production Center, I always show them our video digitization system, and point out that Duke Libraries’ collection of U-matic, VHS and Betacam analog videotapes are ancient relics from the last century. This fall’s first-year students were born in the new millennium. They have little use for physical media, except for perhaps an occasional external thumb-drive. Their concept of video is something you capture on your iPhone or stream online, not play using a crude plastic rectangular-shell. And rewinding videotape? “Like… what is that?, it’s so… weird!”
So, imagine my surprise when I recently walked into Raleigh’s brand new Alamo Drafthouse Cinema, and entered their Video Vortex, a massive library of over 75,000 video titles on VHS and DVD, that are free for customers to check out and watch at home. Video Vortex even rents out VHS players, another historical artifact. This may seem odd at a time and everyone is streaming movie content online. But, Video Vortex specializes in movies you can’t get from Netflix, Amazon and other streaming services. Many of their titles are out of print, and some of these films were never released on DVD, or in any digital format, so the only way you can see them is on VHS.
Walking through the VHS collection is like going to a run-down grindhouse movie theater in 1975, or tuning into an obscure cable-TV channel at 3 A.M. in 1987. Many of the films would be classified as “exploitation:” cheaply-made horror, cult or action titles that never had a chance at the Oscars, and are “so bad, they’re good,” like “Blood Orgy of the Leather Girls.” But there’s also critically acclaimed films like Frank Perry’s “Last Summer,” which earned an academy award nomination in 1969. Due to copyright issues or lack of funds, these two films have never made it into the digital realm, and can only be seen on VHS.
Josh Schafer is co-manager and “VHS Culture Captain” of Video Vortex. He moved here from New Jersey to work in the vortex, because he’s a longtime connoisseur and expert on the VHS format, and even publishes a VHS fanzine called “Lunchmeat.”
“The whole goal here is to not just reimagine the video store, and give people that feeling and experience again, but also give people this library, this community asset where both film-lovers and the casual movie-goer alike, can come in and explore all kinds of cinema, for free,” says Schafer. The Alamo’s lobby, where Video Vortex lives, is decorated with rare movie posters, giant VHS facsimiles, and has tables where film-nerds can congregate, order from the Alamo’s full kitchen and bar, and discuss their favorite obscure animation titles.
Skip Elsheimer of AV Geeks has taken on the job of helping to maintain the Video Vortex collection, which involves cleaning off mold, splicing tape, fixing cases and repairing DVDs. “A lot of these videotapes and DVDs were boxed up for years in storage spaces that were not ideal,” says Skip. “We do TLC on these titles, many of which don’t exist in any other format.”
DVDs are actually harder to fix and reclaim than videotape. Skip says the rescue rate of VHS is about 90%, because he can swap out tape, put it in a new cassette case, splice it, etc. But once the lamination separates on a DVD, or if there’s a significant scratch, it’s toast, because the laser can no longer read the data, and there’s no way to retrieve it. So much for the idea of digital = permanent. Or as the VHS Culture Captain says, “only analog is real.”
In addition to Video Vortex, Alamo Drafthouse Cinema offers a mix of first-run, independent and vintage films on 11 screens. The comfy theater seats recline, and customers can order an eclectic mix of foods, cocktails, craft-beers and wine, right from their seat. Most everyone who works at Alamo is a movie fan, and it shows in everything from the vintage movie posters that line the walls, to the enthusiasm of the employees. The only way to dampen that enthusiasm is if you talk or text in the theater, because, after one warning, you will be asked to leave, as explained in this colorful public service announcement.
However, when I’m not at Duke, I do like to watch TV at home, in high-definition. This past Christmas, the television in my living room decided to kick the bucket, so I set out to get a new one. I went to my local Best Buy and a few other stores, to check out all the latest and greatest TVs. The first thing I noticed is that just about every TV on the market now features 4K ultra-high-definition (UHD), and many have high dynamic range (HDR).
Before we dive into 4K, some history is in order. Traditional, standard-definition televisions offered 480 lines of vertical resolution, with a 4:3 aspect ratio, meaning the height of the image display is 3/4 the dimension of the width. This is how television was broadcast for most of the 20th century. Full HD television, which gained popularity at the turn of the millennium, has 1080 pixels of vertical resolution (over twice as much as SD), and an aspect ratio of 16:9, which makes the height barely more than 1/2 the size of the width.
16:9 more closely resembles the proportions of a movie theater screen, and this change in TV specification helped to usher in the “home theater” era. Once 16:9 HD TVs became popular, the emergence of Blu-ray discs and players allowed consumers to rent or purchase movies, watch them in full HD and hear them in theater-like high fidelity, by adding 5.1 surround sound speakers and subwoofers. Those who could afford it started converting their basements and spare rooms into small movie theaters.
The next step in the television evolution was 4Kultra-high-definition (UHD) TVs, which have flooded big box stores in recent years. 4K UHD has an astounding resolution of 3840 horizontal pixels and 2160 vertical pixels, twice as much resolution as HD, and almost five times more resolution than SD. Gazing at the images on these 4K TVs in that Best Buy was pretty disorienting. The image is so sharp and finely-detailed, that it’s almost too much for your eyes and brain to process.
For example, looking at footage of a mountain range in 4K UHD feels like you’re seeing more detail than you would if you were actually looking at the same mountain range in person, with your naked eye. And high dynamic range (HDR) increases this effect, by offering a much larger palette of colors and more levels of subtle gradation from light to dark. The latter allows for more detail in the highlight and shadow areas of the image. The 4K experience is a textbook example of hyperreality, which is rapidly encroaching into every aspect of our modern lives, from entertainment to politics.
The next thing that dawned on me was: If I get a 4K TV, where am I going to get the 4K content? No television stations or cable channels are broadcasting in 4K and my old Blu-ray player doesn’t play 4K. Fortunately, all 4K TVs will also display 1080p HD content beautifully, so that warmed me up to the purchase. It mean’t I didn’t have to immediately replace my Blu-ray player, or just stare at a black screen night after night, waiting for my favorite TV stations to catch up with the new technology.
The salesperson that was helping me alerted me to the fact that Best Buy also sells 4K UHD Blu-ray discs and 4K-ready Blu-ray players, and that some content providers, like Netflix, are streaming many shows in 4K and in HDR, like “Stranger Things,” “Daredevil” and “The Punisher,” to name a few. So I went ahead with the purchase and brought home my new 4K TV. I also picked up a 4K-enabled Roku, which allows anyone with a fast internet connection and subscription to stream content from Netflix, Amazon and Hulu, as well as accessing most cable-TV channels via services like DirecTV Now,YouTube TV, Sling and Hulu.
I connected the new TV (a 55” Sony X800E) to my 4K Roku, ethernet, HD antenna and stereo system and sat down to watch. The 1080p broadcasts from the local HD stations looked and sounded great, and so did my favorite 1080p shows streaming from Netflix. I went with a larger TV than I had previously, so that was also a big improvement.
To get the true 4K HDR experience, I upgraded my Netflix account to the 4K-capable version, and started watching the new Marvel series, “The Punisher.” It didn’t look quite as razor sharp as the 4K images did in Best Buy, but that’s likely due to the fact that the 4K Netflix content is more compressed for streaming, whereas the TVs on the sales floor are playing 4K video in-house, that has very little, if any, compression.
As a test, I went back and forth between watching The Punisher in 4K UHD, and watching the same Punisher episodes in HD, using an additional, older Roku though a separate HDMI port. The 4K version did have a lot more detail than it’s HD counterpart, but it was also more grainy, with horizons of clear skies showing additional noise, as if the 4K technology is trying too hard to bring detail out of something that is inherently a flat plane of the same color.
Also, because of the high dynamic range, the image loses a bit of overall contrast when displaying so many subtle gradations between dark and light. 4K streaming also requires a fast internet connection and it downloads a lot of data, so if you want to go 4K, you may need to upgrade your ISP plan, and make sure there are no data caps. I have a 300 Mbps fiber connection, with ethernet cable routed to my TV, and that works perfectly when I’m streaming 4K content.
I have yet to buy a 4K Blu-ray player and try out a 4K Blu-ray disc, so I don’t know how that will look on my new TV, but from what I’ve read, it more fully takes advantage of the 4K data than streaming 4K does. One reason I’m reluctant to buy a 4K Blu-ray player gets back to content. Almost all the 4K Blu-ray discs for sale or rent now are recently-made Hollywood movies. If I’m going to buy a 4K Blu-ray player, I want to watch classics like “2001: A Space Odyssey,”“The Godfather,”“Apocalypse Now” and “Vertigo” in 4K, but those aren’t currently available because the studios have yet to release them in 4K. This requires going back to the original film stock and painstakingly digitizing and restoring them in 4K.
Some older films may not have enough inherent resolution to take full advantage of 4K, but it seems like films such as “2001: A Space Odyssey,” which was originally shot in 65 mm, would really be enhanced by a 4K restoration. Filmmakers and the entertainment industry are already experimenting with 8K and 16K technology, so I guess my 4K TV will be obsolete in a few years, and we’ll all be having seizures while watching TV, because our brains will no longer be able to handle the amount of data flooding our senses.
A few weeks ago at Duke Libraries, we had our 5th annual “Screamfest.” The event, which occurs on Halloween, is when the David M. Rubenstein Rare Book & Manuscript Library shows off unique holdings related to extrasensory perception, premature burial, 16th century witches, devils (not just blue ones), creepy advertisements, eerie pulp fiction, scary zines and more. Attendees sometimes show up in costumes, and there is of course, lots of candy. I always eat too much.
As I was looking through the various materials on display, there was one item in particular that seemed to draw me in. In fact, you could say I was compelled to read it, almost as if I was not in control of my actions! It’s a simple one-page letter, written in 1949 by Luther M. Schulze, a Lutheran pastor in Washington, D.C., addressed to J.B Rhine, the scientist who founded parapsychology as a branch of psychology, and started the Duke Parapsychology Laboratory, which operated at Duke University from 1930 until the 1960’s. Parapsychology is the study of phenomena such as telepathy, clairvoyance, hypnosis, psychokinesis and other paranormal mysteries.
The letter begins: “We have in our congregation a family who are being disturbed by poltergeist phenomena. It first appeared about January 15, 1949. The family consists of the maternal grandmother, a fourteen (year) old boy who is an only child, and his parents. The phenomena is present only in the boy’s presence. I had him in my home on the night of February 17-18 to observe for myself. Chairs moved with him and one threw him out. His bed shook whenever he was in it.” The letter also states that his family says that “words appeared on the boy’s body” and he “has visions of the devil and goes into a trance and speaks in a strange language”
As a fan of classic horror films, this letter immediately reminded me of what is generally regarded to be the scariest movie of all time, “The Exorcist.” I was too young to see the film when it was originally released in 1973, but got the chance to see the director’s cut on the big screen in 2000. It’s definitely the scariest movie of all time, but not because of gratuitous gore like you see in today’s monotonously-sadistic slasher films. The Exorcist is the scariest movie ever because it expertly taps into one of the central fears within our Judeao-Christian collective subconscious: That evil isn’t just something we battle outside of ourselves. The most frightening evil of all is that which can take root within us.
It turns out there’s a direct link between this mysterious letter to J.B Rhine and “The Exorcist.” William Peter Blatty, who wrote the 1971 novel and adapted it for the film, based his book on a real-life 1949 exorcism performed by Jesuit priests in St. Louis. The exorcism was performed on a 14-yr-old boy under the pseudonym of “Roland Doe” and that is the same boy that Rev. Schulze is referring to in his letter to J.B. Rhine at Duke. When Rhine received the letter, Roland’s family had taken him to St. Louis for the exorcism, having given up on conventional psychiatry. Blatty changed the gender and age of the child for his novel and screenplay, but many of the occurances described in the letter are recognizable to anyone familiar with the book or movie.
Unfortunately for this blog post, poltergeists or demons or psychosomatic illnesses (depending on your point of view) often vanish as unexpectedly as they show up, and that’s what happened in this case. After an initial reply to the letter from L.E. Rhine, his wife and lab partner, J.B. Rhine responded to Rev. Schulze that he was “deeply interested in this case,” and that “the most likely normal explanation is that the boy is, himself led to create the effect of being the victim of mysterious agencies or forces and might be sincerely convinced of it. Such movements as those of the chair and bed might, from your very brief account of them, have originated within himself.” Part of the reason Rhine was successful in his field is that he was an empirical skeptic. Rhine later visited Schulze in person, but by then, the exorcism had ended, and Roland’s condition had returned to normal.
According to subsequent research, Roland married, had children and leads a quiet, ordinary life near Washington, D.C. He refuses to talk about the events of 1949, other than saying he doesn’t remember. In the mid-1960’s, Duke and J.B. Rhine parted ways, and the Duke Parapsychology Lab closed. This was likely due in part to the fact that, despite Rhine’s extensive research and empirical testing, parapsychology was, and still is, considered a dubious pseudoscience. Duke probably realized the association wasn’t helping their reputation as a stellar academic institution. The Rhines continued their research, setting up the “Foundation for Research on the Nature of Man,” independently of Duke. But the records of the Duke Parapsychology Laboratory are available for study at Duke Libraries. I wonder what other dark secrets might be discovered, brought to light and exorcized?
As a Digital Production Specialist at Duke Libraries, I work with a variety of obsolete videotape formats, digitizing them for long-term preservation and access. Videotape is a form of magnetic tape, consisting of a magnetized coating on one side of a strip of plastic film. The film is there to support the magnetized coating, which usually consists of iron oxide. Magnetic tape was first invented in 1928, for recording sound, but it would be several decades before it could be used for moving images, due to the increased bandwidth that is required to capture the visual content.
Television was live in the beginning, because there was no way to pre-record the broadcast other than with traditional film, which was expensive and time-consuming. In 1951, Bing Crosby Enterprises (BCE), owned by actor and singer Bing Crosby, demonstrated the first videotape recording. Crosby had previously incorporated audiotape recording into the production of his radio broadcasts, so that he would have more time for other commitments, like golf! Instead of having to do a live radio broadcast once a week for a month, he could record four broadcasts in one week, then have the next three weeks off. The 1951 demonstration ran quarter-inch audiotape at 360 inches per second, using a modified Ampex 200 tape recorder, but the images were reportedly blurry and not broadcast quality.
More companies experimented with the emerging technology in the early 1950’s, until Ampex introduced 2” black and white quadruplex videotape at the National Association of Broadcasters convention in 1956. This was the first videotape that was broadcast quality. Soon, television networks were broadcasting pre-recorded shows on quadruplex, and were able to present them at different times in all four U.S. time zones. Some of the earliest videotape broadcasts were CBS’s “The Edsel Show,” CBS’s “Douglas Edwards with the News,” and NBC’s “Truth or Consequences.” In 1958, Ampex debuted a color quadruplex videotape recorder. NBC’s “An Evening with Fred Astaire” was the first major TV show to be videotaped in color, also in 1958.
One of the downsides to quadruplex, is that the videotapes could only be played back using the same tape heads which originally recorded the content. Those tape-heads wore out very quickly, which mean’t that many tapes could not be reliably played back using the new tape-heads that replaced the exhausted ones. Quadruplex videotapes were also expensive, about $300 per hour of tape. So, many TV stations maximized the expense, by continually erasing tapes, and then recording the next broadcast on the same tape. Unfortunately, due to this, many classic TV shows are lost forever, like the vast majority of the first ten years (1962-1972) of “The Tonight Show with Johnny Carson,” and Super Bowl II (1968).
Quadruplex was the industry standard until the introduction of 1” Type C, in 1976. Type C video recorders required less maintenance, were more compact and enabled new functions, like still frame, shuttle and slow motion, and 1” Type C did not require time base correction, like 2” Quadruplex did. Type C is a composite videotape format, with quality that matches later component formats like Betacam. Composite video merges the color channels so that it’s consistent with a broadcast signal. Type C remained popular for several decades, until the use of videocassettes gained in popularity. We will explore that in a future blog post.
“There is nothing wrong with your television set. Do not attempt to adjust the picture. We are controlling transmission. We will control the horizontal. We will control the vertical. We repeat: there is nothing wrong with your television set.”
That was part of the cold open of one of the best science fiction shows of the 1960’s, “The Outer Limits.” The implication being that by controlling everything you see and hear in the next hour, the show’s producers were about to blow your mind and take you to the outer limits of human thought and fantasy, which the show often did.
In regards to controlling the horizontal and the vertical, one of the more mysterious parts of my job is dealing with aspect ratios when it comes to digitizing videotape. The aspect ratio of any shape is the proportion of it’s dimensions. For example, the aspect ratio of a square is always 1 : 1 (width : height). That means, in any square, the width is always equal to the height, regardless of whether a square is 1-inch wide or 10-feet wide. Traditionally, television sets displayed images in a 4 : 3 ratio. So, if you owned a 20” CRT (cathode ray tube) TV back in the olden days, like say 1980, the broadcast image on the screen was 16” wide by 12” high. So, the height was 3/4 the size of the width, or 4 : 3. The 20” dimension was determined by measuring the rectangle diagonally, and was mainly used to categorize and advertise the TV.
Almost all standard-definition analog videotapes, like U-matic, Beta and VHS, have a 4 : 3 aspect ratio. But when digitizing the content, things get more complicated. Analog video monitors display pixels that are tall and thin in shape. The height of these pixels is greater than their width, whereas modern computer displays use pixels that are square in shape. On an analog video monitor, NTSC video displays at roughly 720 (tall and skinny) pixels per horizontal line, and there are 486 visible horizontal lines. If you do the math on that, 720 x 486 is not 4 : 3. But because the analog pixels display tall and thin, you need more of them aligned vertically to fill up a 4 : 3 video monitor frame.
When Duke Libraries digitizes analog video, we create a master file that is 720 x 486 pixels, so that if someone from the broadcast television world later wants to use the file, it will be native to that traditional standard-definition broadcast specification. However, in order to display the digitized video on Duke’s website, we make a new file, called a derivative, with the dimensions changed to 640 x 480 pixels, because it will ultimately be viewed on computer monitors, laptops and smart phones, which use square pixels. Because the pixels are square, 640 x 480 is mathematically a 4 : 3 aspect ratio, and the video will display properly. The derivative video file is also compressed, so that it will stream smoothly regardless of internet bandwidth limits.
“We now return control of your television set to you. Until next week at the same time, when the control voice will take you to – The Outer Limits.”
Looking through Duke Libraries’ AdViews collection of television commercials, I recently came across the following commercial for Beech-Nut chewing tobacco, circa 1970:
Obviously this was before tobacco advertising was banned from the television airwaves, which took effect on January 2, 1971, as part of the Public Health Cigarette Smoking Act, signed by President Richard Nixon. At first listen, the commercial’s country-tinged jingle, and voice-over narration sound like “The Man in Black,” the legendary Johnny Cash. This would not be unusual, as Cash had previously done radio and television promos sponsored by Beech-Nut, and can be seen in other 1970’s television commercials, shilling for such clients as Lionel Trains, Amoco and STP. Obviously, Johnny was low on funds at this point in his career, as his music seemed old-fashioned to the younger generation of record-buyers, and his popularity had waned. Appearing in television commercials may have been necessary to balance his checkbook.
However, the Beech-Nut commercial above is mysterious. It sounds like Johnny Cash, but the pitch is slightly off. It’s also odd that Johnny doesn’t visually appear in the ad, like he does in the Lionel, Amoco and STP commercials. Showing his face would have likely yielded higher pay. This raises the question of whether it is in fact Johnny Cash in the Beech-Nut commercial, or someone imitating Johnny’s baritone singing voice and folksy speaking style. Who would be capable of such close imitation? Well, it could be Johnny’s brother, Tommy Cash. Most fans know about Johnny’s older brother, Jack, who died in a tragic accident when Johnny was a child (ironically, the accident was in a sawmill), but Johnny had six siblings, including younger brother Tommy.
Tommy Cash carved out a recording career of his own, and had several hit singles in the late 60’s and early 70’s, by conveniently co-opting Johnny’s sound and image. One of his biggest hits was “Six White Horses,” in 1969, a commentary on the deaths of JFK, RFK and MLK. Other hits included “One Song Away,” and “Rise and Shine.” Johnny and Tommy can be seen performing together in this performance, singing about their father. It turns out Tommy allowed his voice to be used on television commercials for Pepsi, Burger King, and Beech-Nut. So, it’s likely the Beech-Nut commercial is the work of Tommy Cash, rather than his more famous brother. Tommy, now in his 70’s, has continued to record as recently as 2008. Tommy’s also a real estate agent, and handled the sale of Johnny Cash’s home in Tennessee, after the deaths of Johnny and wife June Carter Cash in 2003.
In the Digital Production Center, many of the videotapes we digitize have “bars and tone” at the beginning of the tape. These are officially called “SMPTE color bars.” SMPTE stands for The Society of Motion Picture and Television Engineers, the organization that established the color bars as the North American video standard, beginning in the 1970s. In addition to the color bars presented visually, there is an audio tone that is emitted from the videotape at the same time, thus the phrase “bars and tone.”
The purpose of bars and tone is to serve as a reference or target for the calibration of color and audio levels coming from the videotape during transmission. The color bars are presented at 75% intensity. The audio tone is a 1kHz sine wave. In the DPC, we can make adjustments to the incoming signal, in order to bring the target values into specification. This is done by monitoring the vectorscope output, and the audio levels. Below, you can see the color bars are in proper alignment on the DPC’s vectorscope readout, after initial adjustment.
We use Blackmagic Design’s SmartView monitors to check the vectorscope, as well as waveform and audio levels. The SmartView is an updated, more compact and lightweight version of the older, analog equipment traditionally used in television studios. The Smartview monitors are integrated into our video rack system, along with other video digitization equipment, and numerous videotape decks.
If you are old enough to have grown up in the black and white television era, you may recognize this old TV test pattern, commonly referred to as the “Indian-head test pattern.” This often appeared just before a TV station began broadcasting in the morning, and again right after the station signed off at night. The design was introduced in 1939 by RCA. The “Indian-head” image was integrated into a pattern of lines and shapes that television engineers used to calibrate broadcast equipment. Because the illustration of the Native American chief contained identifiable shades of gray, and had fine detail in the feathers of the headdress, it was ideal for adjusting brightness and contrast.
When color television debuted in the 1960’s, the “Indian-head test pattern” was replaced with a test card showing color bars, a precursor to the SMPTE color bars. Today, the “Indian-head test pattern” is remembered nostalgically, as a symbol of the advent of television, and as a unique piece of Americana. The master art for the test pattern was discovered in an RCA dumpster in 1970, and has since been sold to a private collector. In 2009, when all U.S. television stations were required to end their analog signal transmission, many of the stations used the Indian-head test pattern as their final analog broadcast image.
If you happen to be rummaging through your parents’ or grandparents’ attic, basement or garage, and stumble upon some old reel-to-reel audiotape, or perhaps some dust-covered videotape reels that seem absurdly large & clunky, they are most likely worthless, except for perhaps sentimental value. Even if these artifacts did, at one time, have some unique historic content, you may never know, because there’s a strong chance that decades of temperature extremes have made the media unplayable. The machines that were once used to play the media are often no longer manufactured, hard to find, and only a handful of retired engineers know how to repair them. That is, if they can find the right spare parts, which no one sells anymore.
However, once in a while, something that is one of a kind miraculously survives. That was the case for Troy Haupt, a resident of North Carolina’s Outer Banks, who discovered that his father, Martin Haupt, had recorded the very first Super Bowl onto 2” Quadruplex color videotape directly from the 1967 live television broadcast. After Martin passed away, the tapes ended up in Troy’s mother’s attic, yet somehow survived the elements.
What makes this so unique is that, in 1967, videotape was very expensive and archiving at television networks was not a priority. So the networks that aired the first Super Bowl, CBS and NBC, did not save any of the broadcast.
But Martin Haupt happened to work for a company that repaired professional videotape recorders, which were, in 1967, cutting edge technology. Taping television broadcasts was part of Martin’s job, a way to test the machines he was rebuilding. Fortunately, Martin went to work the day Super Bowl 1 aired live. The two Quadruplex videotapes that Martin Haupt used to record Super Bowl 1 cost $200 each in 1967. In today’s dollars, that’s almost $3000 total for the two tapes. Buying a “VCR” at your local department store was unfathomable then, and would not be possible for at least another decade. Somehow, Martin missed recording halftime, and part of the third quarter, but it turns out that Martin’s son Troy now owns the most complete known video recording of Super Bowl 1, in which the quarterback Bart Starr led the Green Bay Packers to a 35-10 victory over the Kansas City Chiefs.
For music fans, another treasure was uncovered in a storage locker in Marin County, CA, in 1986. Betty Cantor-Jackson worked for The Grateful Dead’s road crew, and made professional multi-track recordings of many of their best concerts, between 1971-1980, on reel-to-reel audiotape. The Dead were known for marathon concerts in which some extended songs, like “Dark Star” could easily fill an entire audio reel. The band gave Betty permission to record, but she purchased her own gear and blank tape, tapping into the band’s mixing console to capture high-quality, soundboard recordings of the band’s epic concerts during their prime era. Betty held onto her tapes until she fell on hard times in the 1980’s, lost her home, and had to move the tapes to a storage locker. She couldn’t pay the storage fees, so the locker contents went up for auction.
Some 1000 audio reels ended up in the hands of three different buyers, none of whom knew what the tapes contained. Once the music was discovered, copies of the recordings began to leak to hardcore tape-traders within the Deadhead community, and they became affectionately referred to as “The Betty Boards.” It turns out the tapes include some legendary performances, such as the 1971 Capitol Theatre run, and the May 1977 tour, including “Barton Hall, May 8, 1977,” considered by many Deadheads as one of the best Grateful Dead concerts of all time.
You would think the current owners of Super Bowl 1 and Barton Hall, May 8, 1977 would be sitting on gold. But, that’s where the lawyers come in. Legally, the people who possess these tapes own the physical tapes, but not the content on those tapes. So, Troy Haupt owns the 2” inch quadriplex reels of Super Bowl 1, but the NFL owns what you can see on those reels. The NFL owns the copyright of the broadcast. Likewise, The Grateful Dead owns the music on the audio reels, regardless of who owns the physical tape that contains the music. Unfortunately, for NFL fans and Deadheads, this makes the content somewhat inaccessable for now. Troy Haupt has offered to sell his videotapes to the NFL, but they have mostly ignored him. If Troy tries to sell the tapes to a third party instead, the NFL says they will sue him, for unauthorized distribution of their content. The owners of the Grateful Dead tapes face a similar dilema. The band’s management isn’t willing to pay money for the physical tapes, but if the owners, or any third party the owners sell the tapes to, try to distribute the music, they will get sued. However, if it weren’t for Martin Haupt and Betty Cantor-Jackson, who had the foresight to record these events in the first place, the content would not exist at all.
