Hello, I've jut been hit by an avidemux problem, may be worth a bugreport if not already fixed :-) however openSUSE Leap 15.3 seems to use the same 2.8.0 version as the appimage available on the avidemux side. The problem is pretty odd: the sound is shifted some seconds late. When the singer stop singing and drop the mic, one can still hear his voice. Of course not on the source (not an echo :-(). This seems to happen only on special situation. I'm cutting videos from a Canon HF G30 camcorder. Full HD, 28Mb/s 50fps. When loading, avidemux write it's own index file, then ask for something to fix (This video contains B-frames, but presentation time stamps (PTS) are either missing or monotonically increasing. Avidemux can try to reconstruct correct PTS by decoding the entire video. This may take a lot of time. Proceed?), I always say "yes", and have to wait around 3 mn (20 minutes video, 4Gb MTS file). no problem there. I select a part of the video (say a song, cut to i-frame), write it as raw copy mkv file, delete the part already done and go for the next. At a moment I have a song half on the present file and half on the next, so I append the next one, and so on. The shift may appear after several append It's not easy to see, cause my video is not a closeup. The resulting file is much too big to be shared, and the problem is not immediately visible, so I don't know what to do to help debugging (but right now I'm obliged to redo one day work :-() any clue? worth a bugzilla? thanks jdd -- http://dodin.org http://valeriedodin.com
