So I loaded avidemux last night and gave IT a shot. "Better" is a phrase
that comes to mind, at least it's easy enough to use. Getting rid of
commercials was pretty easy after indexing, and saving instead of a 12 - 15
hour process was about 30 minutes...
That's about as best as I can say. The video STILL doesn't work, it now
looks like it's playing on x2 and there's still no sound. I've tried AVI
and mpeg video saving routines, all a no go.
I did not tell it to use an external sound source, but I don't think this
recording HAS an external sound source, the sound and video are all recorded
in the same file I'm pretty sure. IT is a high def recording so are there
settings I'm missing?
For the MythTranscode line above -c and -s are taking a chanid and a
starttime are they not? This video is outside of MythTV, there is no
database information for it, thus there is no starttime or chanid associated
with the recording. It was originally recorded through Myth but was
transcoded and exported (without removing commercials) a long time ago. The
original video works (sound/video) but, obviously, there's still commercials
in it that I'd like to get rid of. Thus the external editor.
