Thanks to both. I am talking about encoding to a smaller file size. Any

mencoder would be a good program.

I would suggest first playing it with mplayer and seeing what the current
encoding is, if it is already xvid/divx/x264 encoded you won't
I've found mencoder not to be quite as functional as transcode for certain
applications.  However, I do agree with Roger, you need to find out the
existing codec/aspect ratio before tinkering with the file. Instead of using
mplayer, I'd try just using 'file <videoname>', that gives you a good amount
of info on the file (just in case the file is on a remote system as mine are
sometimes).

I do have a couple of standard lines for adjusting video files that I'll be
glad to share if you want.  They aren't anything more than typical
transcode/mencoder lines with basic options that I"ve saved since I can't
always remember the options.

Thanks to all for all helpful comments.

The details of my file are:

$ file example.avi
example.avi: RIFF (little-endian) data, AVI, 1024 x 768, 30.00 fps,
video: uncompressed
$

That looks like raw video to me. There's no codec mentioned at or, nor any audio stream encoded. And 1024X768 @30fps has to be a monster file size. You should be able to drop that file down a lot with almost any codec. I would suggest Xvid (or H264, but I like Xvid more) and use the AC3 audio codec (if audio is present).

May i ask what this file is? And where you got it? Is it an output from a video camera? I've never seen raw video at that resolution before.
