California's Golden History

February 29, 2016

The great state of California is the most populous in the United States and one of the largest, with a rich and complex history dating back before the country's founding. For several decades, a relatively obscure series of television shows created by a TV personality and Tennessee transplant named Huell Howser explored some of the most fascinating little-known nooks and crannies of the Golden State.

Digital Revolution digitized and preserved the entire Huell Howser PBS TV show collection for Chapman University. Created out of KCET-TV in Los Angeles, the shows were produced to run on PBS TV stations throughout California.

The collection contains over 1,100 programs including his first series from 1987, Video Log. It also includes subsequent series California’s Gold, California’s Missions, Visiting with Huell Howser, Road Trip with Huell Howser, California’s Golden Parks, California’s Green, California’s Water and his final series Downtown.

His most well known show California’s Gold was produced for 18 seasons. Mr. Howser passed away over three years ago, but the content he created is a timeless reminder of California's wildly diverse history, culture and personality. From exploring Spanish missions to tracing California's water from the Colorado River to the Hoover Dam, Huell Howser was a warm and friendly guide through his adopted state's  idiosyncrasies and is remembered fondly by a generation of Californians. His shows still air regularly in syndication across the state.

“The video tape formats were all digital betacam and betacamSP. They are evaporated metal based tapes that hold up better over time than oxide based tapes like ¾” Umatic, 1” or plain old betacam. So the digital files look great,” said Digital Revolution CEO Paul Grippaldi.

Digital Revolution’s directive from Chapman University was not only to digitize the tapes into 10-bit uncompressed files, but also to extract the closed captions that were recorded into the programs. Then MP4’s were created for Word Press Web Player and married with the captions. The end result was Chapman University uploading the entire Huell Howser collection onto the University’s website. The viewer now has the option to watch the shows with captions, making them ADA compliant.

Seventeen of the shows were never closed captioned, so Digital Revolution captioned those shows and digitized them for the collection. In the end there was over eighty terabytes of data created. Digital Revolution not only put the files onto hard drives and back up hard drives, but also made LTO data tapes for long term archiving.

Chapman University has a wonderful Huell Howser museum at their Leatherby Libraries. It’s like taking a walk through California history. Now everyone can enjoy his TV shows for decades to come.

Moldy Tapes

November 17, 2015

Greetings, Digital Citizens! Welcome to Digital Revolution's new blog!

Mile End Films is making a documentary about actor Burt Reynolds and asked us to perform video tape transfers and media preservation for seven 3/4" Umatic Tapes. These tapes were particularly old and several had some mold build-up from being stored in a damp environment. With 3/4" Umatic tapes dating back more than 30 years Digital Revolution performs the following preparation: Bake, Hand Clean, and Transplant the tape reels into fresh 3M Broadcast Color Plus shells. All of these procedures need to be done carefully and thoughtfully. In the case of moldy tapes we use gloves, a mask and hand clean the entire tape with an alcohol cloth.

-Baking gets the moisture out of the tape so that it doesn't stick in the machine or rip oxide off of as it is played.

-Since oxide based tapes decompose relatively quickly, cleaning them keeps the machine playback heads from clogging and makes for a more residue free transfer. Alcohol acts as a good cleaner and kills mold.

-3M Broadcast Color Plus tape shells are made of all plastic non-moving parts so the tape tracks properly in them. We have them in stock as part of our transfer tools. Other tape shells have moving parts and springs that can dry out over time and cause poor tracking during playback.

The client's file format preference was Pro Res 422HQ. They were happy with our first set of digitized tapes. They had been having transfers done in other parts of the country as well. We told them to send us all of their “hopeless” tapes.  They did. Two dozen more ¾” Umatics, all of them with severe moisture or mold build up. The programs were of particular interest to the filmmaker and included The Mike Douglas Show, The Tonight Show, Awards Shows, Riverboat, Love American Style, Burt Reynolds late night shows etc.

The tapes spanned 1977-1983 and were manufactured by various companies including Sony, 3M and DuPont.  Some of the tapes we had to bake longer than normal and hand clean several times because of the excessive mold & moisture. However, we were able to get all of them to playback except for the two DuPont Tapes. There were many companies that went into and out of the video tape manufacturing business over four decades. Our experience tells us that Sony, Fuji, Maxell, 3M (Scotch), Ampex & Quantegy last the longest.

Keep your eyes peeled for this upcoming documentary. It should be very entertaining!
