- extract video from dvd, make frame accurate edits
- Posted by Ralph Snart on November 28th, 2003
say i extract a clip from a dvd and i want to make some
frame-accurate edits. what format would i be best off converting
the dvd video into? avi? leave it as mpeg-2?
and then when i want to reassemble it, is there any way i can
avoid a re-encode? i know virtualdub can do "Direct Stream Copy"
but i'm not sure it will work on mpeg-2.

Leaving the video in MPEG-2 should be the highest quality
route, but conversion to AVI may give you more software
options.
Depends on the software, but for any edits on non-GOP boundaries,
some reencoding will be required.
VirtualDub doesn't handle MPEG-2. There is a hacked version
which does, but I've never used it so have no idea how it
handles MPEG-2. The official version of VirtualDub does
support MPEG-1, and it does it by always decoding--output
is always AVI.

Yeah, that's the problem. Even if you can get it to manage Mpeg2 (a
way to get that could be, for instance, to load the mpeg clip through
an Avisynth script), what you get out is an Avi So if you want an mpeg
back, you would have to reencode the output Avi.
Whereas an mpeg editing software would reencode only the (usually)
small amount of frames between the cut and the next GOP-boundary (I
frame).
