From Wikipedia:

... It was designed to encode 320x240 resolution video at 1x (150 kbyte/s) CD-ROM transfer rates...

Bitrate:

Despite the apparent intended bitrate/resolution of 150kbps (that's kilobits) and 320x240...

I assume you were extracting your 150kbps from the article, in which case 150kbps to 1200kbps (150kBps) is a rather big difference. BTW it's b vs B that is the distinction, not k vs K.

Anyway, I don't have much encoding experience, but I'd expect not much quality loss if you were to just re-encode the video. It'd be nice to have the original source, but seeing as it's from 1961, it's more likely on VHS than on CD, meaning it'd be rather difficult to extract the video without some specialized equipment. And yes, use 15 fps or so - probably won't even be much of a difference. I'd probably go with 96kbps audio too, maybe 128kbps if the size difference isn't much, which it shouldn't be.

Since Cinepak is a rather old codec, you can probably expect support for it in most programs you use. I'll point you at Handbrake, but like I said I have very limited experience. Doesn't hurt to just give it a shot and see what the results give you, though.

@FK:  I wouldn't be the least bit surprised if that were only one among many oversights in my analysis of this file and what's "wrong" with it.  I do intend to take a few what-the-hell style cracks at a re-encode.  I'll post back here with my findings unless some additional help/recommendations/lessons in units of digital information come my way first.  Thanks for your insights.

wizisi2k:
it might be worth it to UL the source file somewhere for people to take a crack at seeing what can be done to improve it

Freedom Kira:
Uh, download a 600MB file of 22min of B/W video just to see how to decrease the size? And asking the guy to upload this file? Really?
I think I'd rather use my bandwidth elsewhere. =P
