No I didn't choose noise reduction. Searching through the mail list
archive, I see various reports that it takes all sorts of times. Some
people, like you, say it is hours. I saw others, one for example, said
it took 4 days!
I am seeking to understand what the difference is, and how to avoid long
processing runs. Your comment about noise reduction was something I
actually read about already, but thanks anyway. Still doesn't explain
the difference. Were you using --transcode, or ffmpeg ? I can export
it to VCD format (more processing I would have thought, because the
change is greater) in about 1 hour or so using ffmpeg, but as yet the
version of ffmpeg I have found, doesn't support DVD output.
I have just found some info that the DVB-T card outputs DVD suitable
mpeg anyway, so maybe I can avoid the transcode step. I have much to
learn though :-)
