Hi! Can someone please tell me what's the best way to join audio and video?
I have separate audio and video files, and I want to cut the video together with the audio. I can add both to the timeline and group them. That works fine if I just want to drag the clips around: both are moved together. But if I use "Resize item start" or "Resize item end", only one of the clips is resized, not the group.
That makes editing very tediuos, bacause I have to do all the work twice: once for the audio, once for the video. Why isn't there a "Join audio", that does the opposite of "Split audio"? Wouldn't it be very useful? Am I missing something?
Until now I have been merging both clips using ffmpeg, something like:
ffmpeg -i 120518-000.wav -itsoffset 30.93 -i out_0002.mkv -shortest -vcodec copy -acodec copy new_out_0002.mkv
but for some reason, since a few days ago, the merged video plays fine on VLC, but if I try importing it into Kdenlive, I get:
[swscaler @ 0xaa2ddca0] Unknown format is not supported as input pixel format
and it fails to import.
Any suggestions about how to edit and audio and a video clip as they were one?
