View Full Version : determine unknown [old] codec... help!

08-28-2009, 08:35 PM
I've got several folders full of AVI animations created in 1999 (passed to me by a client). I can't figure out what codec they are, and they won't play back. I've got k-lite full installed, even gspot and MediaInfo say unknown. VLC doesn't help. FFMPEG doesn't play back.

I don't have cleaner or anything like that. (Have Vista 64, MBP with Leopard, and XP 32 access to try different things). Maybe if I started up my old win2K laptop, would it help?

What were some common and not so common obsolete AVI codecs from the '99 era?

Cinepak or Microsoft Video. Both should be part of the standard codecs though.
Are you sure these ain't any capture card related codecs? Tried Avids Codec LE pack already?

fairly sure it's not a captured vid - they're old medical animations.
Tried Avid codec LE, no go.
When I open the "media information" in VLC, it list like 48 streams, roughly half audio, half video, either as mpga or mpgv, with one at the end that is CVD - type "subtitle". That's as much info as I can gather.

CVD is some CD rom video stuff.

Try burning on a DVD or mounting as an image and playback from there on.

You could also try Super C or Handbrake for decoding.

Try GSpot. It's worked in the past for me to identify old codecs (IV54, etc) that new machines can't find.

If you refer to OP, I already tried GSpot. It said Unknown. Thanks though :thumbsup:

Is it possible to upload one of these clips to a file hosting site? I've not come across a video that I couldn't play on my system, and I have a large number of video players and video information tools installed.

Damn, you got me there... No program is able to play it.
I also cannot find any sensible information when I open the file with a hex editor.
Are you sure that they are video files? Could they not be some sort of 3D data of an ancient piece of software?

Video experts at http://forum.doom9.org/ may be able to help you.

I've got a whole folder full of these, they're supposed to be medical animations.

I'll try at doom9
