Video capture, part XXIV
When I told Fabio about my problem with transcode hanging, he suggested I use ffmpeg.
This wiki entry from Gentoo meant I didn't even have to read the man page.
Wow! ffmpeg takes considerably less time than the way I was doing it before. The resulting MPEG still seems okay. Here's what I did:
$ for file in *.dv > do ffmpeg -i $file -target svcd `basename $file .dv`.mpg > done $ vcdimager -t svcd *.mpg $ cdrecord -v -dao dev=/dev/hdc cuefile=videocd.cue
I am getting some slight wrongness, however, with audio dropouts in addition to a little bit of video noise. I wonder if part of that is taking 8.2 GB of digital video down to 700 MB, or whether it's because the cassette was in the camera for 6 months and got damaged. We haven't been shooting as much video as we used to.
UPDATE: No, it's not the original DV. Must be ffmpeg taking short cuts. It's good to know that if I ever go back and edit all this, the raw content is more perfect than the editor ;-)
BTW, Fabio told me that if I really wanted to do much editing, I should give in and get a Mac.
UPDATE 2: The problem's not apparently in the SVCD, but just in our player downstairs. Looks fine in Totem Movie Player under Ubuntu 5.10.
