DVD rip, what is the maximum quality

I'm going to do some ripping of DVD's with "MPEG Streamclip".

I need to transcode into ProRes files. They are going into a project with other ProRes files.

my questions is:

what resolution and quality should I go for? I don't want to loose any quality but I don't want to make to big files either.

I have full copyright permissions, so no issue there!

Thanks

MPEG Streamclip will show you an (unscaled) option when you go to export. Use that.

You'll probably need to change the pixel aspect once you bring the file in.

Thanks,
it shows me an unscaled with aspect correction option which is great!

But what quality ProRess, I cannot figure out what type is enough, I can see the bit rate from the original DVD, but I suspect I need to go a bit higher on output since ProRes is lossy?

ProRes is a "lossless" codec, MPEG-2 very lossy.

ProRes 422 is going to be perfect for making DVD transcodes. Even LT would probably do the job just fine.

+1

Actually LT would still be overkill. The maximum bit rate allowed by the DVD spec is 9.5Mbps. Most DVD's are much less. The Apple ProRes 422 LT data rate for 720 x 486 is 23 Mbps. You could actually use ProRes 422 Proxy which has a data rate of 10 Mbps which is still higher than any DVD would carry.
