MPEG-2 compression from quicktime source on PC

Wow... nice long title...

I am looking to compress quicktime files to MPEG-2 and am trying to figure out my options right now.

the files are Targa 2000 Pro VLI MJPEG captures at 12 megabits per second. Since the captured files them selves are already taking alot of space, I don't really want to re export uncompressed AVI...

has the QT plugin for TMPGenc been imporved at all? the last time I tried it, it reported 120 frames per second on the QT files.

worse case I am looking at is having to program a QT plugin for AVISynth... which i will get to... but looking for somethign sooner.

ARGH... I haven't been in the forums long enough, and my posts aren't making sense. Quu, look to my reply in the main forum, I hit the wrong button when I replied

This is not a Windows-based solution, but it's how I was able to turn a bunch of Quicktime files (some in standard, open Quicktime codecs, others in proprietary codecs such as Sorenson Video) into MPEG-1 and MPEG-2 files, so I might as well just share it.

One way you might be able to do it is by using transcode and mplayer:

Since you're using MJPEG files, the Quicktime4Linux API (and thus transcode) should be able to directly read them; however, I'm not sure of the specifics of the Targa 2000 VLI MJPEG format. It may work, it may not work.

If that doesn't work, you can try playing the file in mplayer and piping the output to transcode, where you can then do post-processing (if desired) and export to MPEG-2.
