I question the premise instead. This is hardly an 'alternate techline', as it's basically performing slightly worse than a real-world Video CD!
(But to answer your question, it'd only require reducing the quality as much as necessary to get the data - measured in megabytes - down to a size that will fit. You could fit several hours of a small, low-quality video into a VCD, in fact, as it's basically a CD with a special format.)
To fit with the whole idea of an 'alternate' techline, I'd suggest just using wire recording instead. The idea is to have something other than magnetic tape, right?

Basically, in my conworld, the dominant form of analog video is not a videotape format like VHS, but an optical videodisc format like Laser Disc. This format has a number of differences from the Laser Discs of our world, the big one being that it can hold a full hour of footage on each side. Now, presumably, there would have to be a tradeoff on quality to be able to fit twice the footage on a Laser Disc-esque format. My question here is, how much of a tradeoff would there have to be? How could said tradeoff be reduced?
Likely busy writing something.
