On today’s videotape digitization to-do list:

  1. Finish letting the equipment warm up while I do other things. :)

  1. Digitize the last home-recorded tape I picked up weeks ago. (So I can get some more. 😂)

  1. Investigate whether or not I can “gain up” the ~33 minute segment of bad reception in the CBS TV Movie from 1984 that I digitized last night.

  1. Plan backup of existing digitized videos, and subsequent digitization of the half-dozen or so commercial tapes we currently have piled up.

Item number three deserves some explanation / expansion.

When this tape was being recorded, someone moved the antenna so that the signal wasn’t optimum for this channel (probably because they were watching something else on another channel). The resultant recording for this period of time has perfect sound, but the picture is … close to black.

The Line 21 captions - maxing out ~7.5 - 10 IRE - are copyable… with effort… and errors. Recapturing could improve quality, making it worth the time.

At the end of the day, I’m basically seeing how much I can polish a 💩. The reason why it’s worth spending time polishing this particular 💩, is because it turns out that this broadcast contains a rare example of that I discuss in the 1980 Caption System series.

This discovery will require that I revise part of one of those essays, as this sample singlehandedly extends the timespan in which was used… by about two years.

Which is a legitimate surprise.

So… I’m presently digitizing the last home-recorded tape.

Turns out that after the home video shot at the Guggenheim (!!) … there is a recording of a TV movie that aired on the ABC television network. While the reception of WABC was poor/fuzzy/ghosty, the Line 21 caption data is coming through just fine.

Wasn’t expecting that, but a nice bonus to have more ABC network material. 😂

Before-and-after for the beginning of the 33 minutes of bad reception. I think the effort was worth it.

I’d gained up the picture, then raised the black level. While the picture looked a bit like overcooked garbage, there was plenty of Line 21 waveform to work with. 😂

@artandtechnic random question: what are you using to look at the line 21 data? I've got many old tapes I'd love to do that with
