I have 2 versions of the same video from you tube.
Version 1: in 2 separate segments, great video, bad audio with long silences
Version 2: in 1 long file, poor grainy video, great flawless audio
Concatenated, if that is possible, both versions would have the same length.
Question: How can I join the 2 files from Version 1, erase the audio and
supplement it with the audio from version 2 (using programs available in fedora
& rpmfusion repos, of course)?
