On a related video note...
Has anyone ever dealt with source material that's a mix of 4x3 and 16x9?
I am remastering one of our very first DVDs, which someone else edited in the first place (not that I would have caught the problem either at that point...)
There is one scene that is primarily in 16x9, with a b-roll that is 4x3. The existing edit is just a mix of the two, which is extremely distractive/disruptive. So I'm preparing to reassemble everything and am thinking of trimming the 16x9 and slightly enlarging it to be 4x3, so it will match not only with the B-roll but with all the other scenes on the DVD, and then perhaps offering the 16x9 scene (without B-roll) as an added bonus.
I can crop the 16x9 without having to mess with pan-and-scan because of the way it was shot, but there will be a slight decrease in quality because I will have to enlarge it about 20% to fill the 4x3 frame after cropping. Would it be better to have a consistent 4x3 in all scenes with a slight degradation as a result of the enlargement, or would it be better to have one 16x9 scene and a bunch of 4x3 scenes?
