i have a lot of Sony XDCAM footage that i'd like to simplify, i'll try with that later and post results I'm now trying to do the same thing with an older panasonic, remux without reencoding, except for the wrong pixel ratio the mpeg audio track is working correctly, i guess it depends on how the camera works. If you have a better way to do this tell me i'd like to use it but there's not a short way to merge different files via command line or script. here's a short mp4 file with the PCM converted to mp3 via FFmpeg. However, the original files are really big, i have no longer access to those cameras to make a short try. Upload using one of these methods: Upload Hochladen Télécharger Subir It is on both channels, more on the right then on the left.Ĭan you provide an original from the camera, 3 to 10 seconds would do. Quote from: Jan Gruuthuse on September 26, 2017, 02:20:46 PM I think there's a problem with how Avidemux reads from the track, the stream is read as an LPCM stream and that sound may be a clock signal or something like that. Again, the file is from a Panasonic professional camcorder and under MPC-HC it is marked as pcm_bluray codec. I'm trying to use Avidemux as a way to remux AVCHD/H264 streams from professional camcorders into single MP4 files, it's always a pain to archive them or even use them on programs like Adobe Premiere, their folder structure is a mess and the index slows down even powerful machines.Īnyway i found out it should be really easy with Avidemux, just drag and drop the different streams into the program, let it build an index and copy the video stream into a new single file, just re encoding the audio stream at most.īut while using an mts file straight from a panasonic camera i found a problem: with current stable version (2.6) the program failed to find an audio track, with the most recent nightly (2.7 - 170919) it found the audio track but there's this strange tone all over the file (see link attached), it stays in the output file if i encode the track to mp3 and even if i just copy the PCM track to a mkv muxer.
