Avidemux Forum

I see the problem, when you select the audio output on the left, it only changes the audio output for the first track in the video. There were 6 tracks, and the other 5 were still set to "copy" instead of "vorbis". I had to manually go into "audio -> select track" and change every track to use vorbis instead of "copy".

That probably should be fixed.

Now my problem is that when i convert a mp4 file to webm using avidemux, for some reason the file size is actually larger?

Maybe there are multiple audio tracks and some of them aren't Opus or Vorbis. In doubt, please start Avidemux, reproduce the error, close Avidemux and attach admlog.txt from %localappdata%\avidemux directory to your reply.

Just tried both Opus and Vorbis, still says "could not open".

Just tested with the Sep 8th version and i got the same error. "Could not open".

I can't seem to convert files to webm using avidemux, i select vp9 video output and the webm muxer, but i just get an error "Cannot open" during the encoding process...

I can convert to other formats like mp4 though. The original file is a mkv.

Does this happen with the latest available 2.8.2 nightly build?

If it does, please provide a sample.

If the file size is too large for the file to be provided as a sample by the usual tools as WeTransfer, Mega, Dropbox or Google Drive, please at least attach MediaInfo textual analysis for the file in question to your reply (don't try to paste it into the body of the post, CleanTalk is allergic against MediaInfo for whatever reason).

But it will if you disable the DTS audio track, right?

I have an MP4 with DTS-HD Mater/5.1 audio. However, Avidemux shows the audio track as Unknown codec, 6 chan. I need to edit the video using keyframes and save as Copy. When I try to save with Audio Output: copy, I get an error message. Unsupported Audio track 1 out of 1 is incompatible Only AAC, AC3, DTS, E-AC3, MP2, MP3 and Vorbis supported for audio. If I change the output to AAC, the video won't play correctly. If I change it to AC3, Avidemux freezes and won't respond.

First of all, 2.8.1 is extremely outdated by now. Recent 2.8.2 nightly builds are a much better choice.

If the issue persists with the latest available nightly build, please reproduce it, then, prior to launching Avidemux again, attach admlog.txt from %localappdata%\avidemux directory to your reply, if the log file is not too large. You may consistently replace (anonymize) paths in it. If the log is too large to be attached, please ZIP-compress it first.
