![]() ![]() ![]() The initial '-c copy' is superseded later, unless there are more audio streams. ![]() '-map 0' includes everything, but you specify audio encoding for only 1: ':0'. If I remember correctly, ffmpeg normally includes only the first video and audio streams (and also excludes subtitles?). It might be useful to start off with the most basic possible command-line, hopefully get that working and then build up from there. Unless you have very specific reasons not mentioned, there seems to be some redundancy and/or confusion here.

So there is something with the avs Script and the ffmpeg command I guess. I tried some -vsync, -async, -r 25 option, without result (anyway, I'm not sure is I'm using them well)Īs a test, I converted directly the DV sources to x264 : I don't have any desynchronisation. I could use some Delay() function on my avs Script but that's not a relevant option. I guess that the damaged framed are "dropped" or something like that. It's working well with non-damaged sources.īut, with the damaged sources, the audio is coming much later than the video. I use AviSynth for several treatment (Trim, TomsMoComp, Crop, LanczosResize, ConvertToYV12, Convolution3D, Blur) and encode them with ffmpeg. Now, I want to convert my masters (DV) to accessible standards (x264) to share with family. However, some of the sources where damaged. Then, I converted them to DV format (audio in FLAC), which I call "masters". A few years ago, I've captured (with Huffyuv codec) movies from an old camera (analog source). ![]()
