I found some bugs in Avidemux
About audio and sync
- Even if I try to set the language for the various audio tracks, opening the output file in VLC I get only "Track 1", "Track 2"... even reopening in Avidemux the tracks are indicated as Unknown
- By cutting into the video, if there are multiple audio tracks, only the first one is synchronized.
- When I export an audio track from Audio > Save Audio the saved file has no extension. I think it should have the extension more suitable for the export format.
- When I add an audio track (Add audio track) I am forced to select a pure audio file. I would like to be able to select and extract an audio track from a video as well.
About video
- Compressing a video via nvidia is faster, but the output file is bigger!
- I would like the program to estimate the current compression percentage so that the output is not larger than the original.
- I read that among the filters you can add a black rectangle or blur or image to an area of the video for a certain period, but I have not found the filter: Miscellaneous > Logo does not exist!
Request: I would like a filter to blur a face and follow its movements
