Video supported by quicktime 3.0 on 68k mac

I know this sounds crazy.

I want to be able to convert mp4/flv videos to an old codec/format that is supported by quicktime 3.0 on a 68k macintosh. It doesn't have to run super smoothly, I just want semi-not-choppy video and sound.

In order to get some idea, I have opened a video made during the 90s with a really old codec in VLC and see the following under the codec information:

Video

Codec: Cinepak Video (cvid)

Resolution 320x236

Frame rate: 24

Decoded format: 24 bits RGB

Audio

Codec: PCM U8 (raw)

Language: English

Channels: Mono

Sample rate: 22320 Hz

Bits per sample: 8

I tried to convert an mp4 to this format in VLC but there is no encoder for cinepak.

Sooo I am asking for either one of two things.

Either 1. Can someone tell me how to replicate this video format/codec? Preferably using a linux tool... but I am flexible.

Or 2. Can someone tell me another combination of video format/codec that works in quicktime for 68k other than the one listed above? Has anyone had success converting videos for these really old machines? How did you do it?

Thanks!

 
Cinepak is considered a "legacy" codec by this time so it's normally hidden from the export options in QuickTime, but in macOS you can re-enable it with some Terminal magic:

qtdefaults write LegacyCodecsEnabled yes

With that, Cinepak should appear in the list of video compression options in QuickTime's standard Export dialog. Again, this is all in macOS.

I don't know of any Linux tools that can export Cinepak-- it was non-free (patented) until at least 2013. Cinepak's fourCC is 'cvid' though (Compact Video) so that might help you when searching for encoding tools.

 
Did you try that old video on 68k hardware to ensure satisfactory playback? 320x240(ish) at 24fps and 24-bit colour may be pushing it. If you look at videos included with 68k educational software of the day, (Carmen San Diego, multimedia encyclopaedia, etc) it's often at a lower colour bit depth and/or framerate.

It looks like ffmpeg is decode-only, but it appears possible to use the appropriate Windows libraries with mencoder to encode Cinepak. https://forum.videohelp.com/threads/333037-Cinepak-encoder?s=cceb8f4b6f54c77cdf0eaa97f612b51f#post2065258

cool, maybe I can find a sample somewhere. I was thinking 320 sounds a bit big too anyway. I remember the quicktime videos I streamed from Apple's website back in 1998/99 online were much smaller and grainier than that.
