You will need to replicate this configuration 100% which is a difficult task. If the original video was encoded with x264 (not just H.264 but H.264 produced by the x264 encoder), you might be able to extract its configuration from a SEI message, embedded into the video stream (Avidemux prints the content of this message to the log when copying video, else please use mediainfo to oview this message). ![]() If the audio de-sync is constant, this will work, but if its on a curve, youll have to render the audio out to Wav or PCM first. When appending, video codec extradata (Avidemux displays a hexdump of up to 64 bytes of extradata in the video properties dialog) of both videos must match perfectly. Then use the 'shift' option under the audio box. Quote from: Papou on August 11, 2021, 07:18:16 PMI tried re-encoding a section with mp4, x262, Constant Bit rate 1kbps, Black filter and no soundtrack and I'd better let you experiment it than try to describe the "codecs don't match", "can't initialize sound" and crashes I met. anything other than the latest git master) crashed if the audio track disappeared, unsure about that. It is quite possible that earlier versions of Avidemux (i.e. Therefore it is mandatory to add a matching audio track to the black video prior to appending it (and then eventually copypasting to the desired location). Quote from: Papou on August 11, 2021, 07:18:16 PMOtherwise said, what sound will AviDemux use for the span of an appended file that has none?įrom the moment where a sound track goes missing, there will be no sound, even if another segment is added from a reference video which has a sound track. The shortcut would be an insert script, as there is no insert command currently in Avidemux. If you have the black segment loaded after the video, you can first select it then cut and paste it where you want it, you don't need 3 separate files.

The Black Filter approach implies re-encoding is required. You could select/copy/paste a quiet segment from your video at the desired point then apply the Black filter with start/stop parameters. Wouldn't "transform" mean that I would lose some of the existing video? (Which I don't want to do.)
