Converting Fraps footage to Premiere/Vegas compatable AVI

Thanks for the update, novalin. I didn't know Premiere could do that!

Back on topic - converting Fraps files for Premiere: I have Premiere Elements 4 and I find that
Fraps files work very well, but maybe I just happened to have the right codecs installed already.

If your app can't read Fraps files it should help to get ffmpeg (or WinFF).
[EDIT - you need ffdshow for the DirectShow codecs]
[EDIT - I mean, you need ffdshow tryouts. That's the ticket.]

It that last tip doesn't work for you, and you need to convert, I would convert with Huffyuv: it's lossless,
and it's very fast, encoding and decoding - faster than Lagarith; Lagarith does compress better though.

XMedia Recode and Avidemux are good alternatives to VirtualDub for lossless converting.
Avidemux can also combine your 4GB segments by dragging each file into the program.

If you have trouble opening a video file on Vegas/Premiere, try encoding it with uncompressed (PCM) audio.

On a related note: I find H.264/x264 works well as an alternative "near-lossless" codec for archive & intermediate clips. File sizes about are about half as large, but encoding takes twice as long. See this post for more.
EDIT - Premiere is encoding x264 with video breakup for me, so it's back to Huffyuv or Lagarith.

Hi I realise I'm a late poster but I'm having issues with virtual dub, I've tried 32bit, 64bit and even older versions of the software, I'm on Windows 7 64bit.

Every time I try to open my fraps footage in vdub it says "Couldn't locate decompresser for format 'FPS1' (uknown)" I've looked all over the internet and found no other solution than "try 32bit" which hasn't worked.

You must have fraps installed on the computer to play back Fraps videos.

Shukaku is correct. I think you need ffdshow tryouts as well.
