If you search the list, you'll find previous posts on what I've
done. Basically, if there aren't any A/V sync glitches in the capture
(e.g. capturing from tape), I use avidemux2 directly. Basically:
- Capture at 640x480, 5Mbps or so
- Edit commercials from within avidemux
- Choose HQ3D denoise, 1/2 D1 resolution, 2-pass transcoding of video
(roughly 3-4 hours/hour show on 2.4GHz machine)
- Remux .m2v audio
- qdvdauthor for fancy menus
- dvdauthor to master
- mkisofs to image
- growisofs to burn
If the sync is broken, there's a workaround. Basically, it
involves using 'mencoder' to encapsulate the MPEG2 stream into an .avi.
Then use "rebuild b-frames" from within avidemux to resync A/V as an
"AVI." Then transcode as normal. Avidemux can't deal with changing A/V
sync within a capture.
