DVD to DV?

[flemo999]

Is there any way to convert DVD content back to DV format for additional editing and potential reauthoring? I realize there is probably some quality loss as you can't get back to DV quality from an MPEG2 quality.

The other alternative would be conversion to standard MPEG2 files for the same purpose.

DVD is MPEG2 so you don't have to any conversion, just rip or demultiplex to mpv, ac3, dts files and you can edit, reauthor it.

AVI is indeed much more amenable to editing, and there is a way of turning back to AVI files already encoded to MPEG-2. DVD2AVI is one such program, (I use 1.77), where, on opening already ripped *.vobs, there are options to save to AVI, aside from the usual creation of a *.d2v file or demuxing to elementary *.m2v and *.ac3 streams. To specifically turn back MPEG-2 material to DV AVI, a bonafide DV codec should be registered in your system (automatically gets done on installation of most popular NLEs or a FireWire card). One concern for this is space: if you're a glutton for a favorite movie on DV AVI, two hours will set u back about 26GB. On another tack, DVD2AVI creates *.d2v pointer files (from a set of *.vobs), which, together with an another program VFAPI can be converted to *.avi, and thus can be opened with a standard NLE like Premiere. But since the *.d2v and corresponding *.avi files are mere pointer files timeline scrubbing will be slow and may even hang the program. This used to be the only option two years ago when 20GB HDDs were the norm. With 200GB HDDs quite common nowadays and faster PCs at that just saving to DV AVI is best with a view to editing later.
