Hi Guys, I am trying to sync two videos recorded simultaniously from a stereo setup.
I am extracting their audio (mono) and find their offset, which I can easily find in Audacity. With the offset in hand I cut off the start of the earliest video, so they start at the same time. I use the -ss flag for this. ffmpeg -ss 0.75 -i A.mp4 -acodec copy -vcodec copy cut_A.mp4 Hereafter I assemble them side by side into one video using a complex filter. I am however having trouble with their syncronization in the end product. I am therefore wondering if the -ss flag is the right way to do this or if I can achieve syncronization between the videos a different way? I suspect the -ss method is affected by where there are keyframes in the video as I constantly get it wrong more than a second. All ideas are welcome. Kind regards Jesper _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
