I have what appears to be a "handmade" dvd. It has the following files on it:
The VOB files are 1)1023.5MB, 2)1023.5MB and 3)371.8MB

In trying to rip these files with DVDxDV to Quicktime using the 8-bit uncompressed option, I get monster files of 17+GB for the first two and 7.63GB for number 3.

I have not dealt with VOB files in the past, and have never had ripped files this large to bring into FCP. Is there any other option I can use to bring these into FCP and not have the quality degraded. The video is not that wildly good to begin with.

I know that Shane has had a good deal of knowledge about DVDxDV, and he could probably straighten me out within seconds.

    In an ideal world, you might get slightly better quality using the 8bit uncompressed option (as long as the pixel dimensions are 720x480 the native dimensions for NTSC DVD's) but converting to a Quicktime with the DV codec will probably give you results that are just as good. DV is about 5 minutes a gig.

    The other quality issue is that the DVD compression, MPEG2, is very compressed, and has lost a lot of quality that the original had. Once that quality is gone, you can never recover it, no matter what you do. All you can do is make it editable in FCP.

    8 bit uncompressed is massive overkill for the quality of the input. I would pick ProRes as the input codec. It has a nice balance between quality and reasonable file size. It is designed as an intermediate editing codec, which is what this is.
