VDM Error

[The Origonal Head Hunter]

Trying to make a xvid avi I got for Project: Editor into a lossless, since Premiere refuses to export with that on the time line, but I keep getting this error:

Avisynth Open Failure:
AVISource: couldn't locate decompressor for fourcc xvid
(File path)

Couldn't put the video directly into VDM, cause it supposedly wasn't a VFW format, so I tried AVISource, and that still won't work. Any suggestions?

The AVIsource filter use your VFW codec to open your video (If i'm not mistaken), so if VDM tell you that you do not have the codec, it's gonna be the same with AVIsource.

You have 3 solutions:
- Instal the XVID/DIVX codec (what you generally in a codec pack is FFdshow which can read the Xvid, but is not a VFW codec)
- Open you video with FFmpegSource("File_path")
- Open you video with DirectShowSource("File_path")

The problem with the letter two options is that ffmpegsource sometimes shifts the audio so it isn't in sync anymore, and the directshowsource isn't frame accurate so it often causes frame order errors... I think that installing the xvid codec is prolly the best solution.

Installing xvid did it, thanks.

For transcoding purposes, DirectShowSource would work fine - it's just for editing that frame accuracy starts figuring in more.

FFmpegSource, as far as I know, only has issues with audio sync if the file is VFR, which the vast majority of files are not. And actually, from what I've read the 2.0 version of FFmpegSource has a VFR-to-CFR mode, although for other reasons that version is still not recommended.

ffdshow does in fact have a VFW interface, and it works very well. Now, whether the bastards that put together computer-killing codec packs actually include that part of ffdshow is up in the air, but if you grab the most recent version of ffdshow-tryouts from the Sourceforge page then the VFW interface is there.
