I am in the process of capturing old miniDV tapes (and VHS tapes through my miniDV deck), which results in DV formatted files (720 x 480 (640x480), Millions 16-bit integer (Little Endian), Stereo, 48.001 kHZ). In reading about transcoding these files, it sounds like going to H.264 MP4 files is a good bet... but I have questions about this.
First and foremost is the issue of non-square to square pixels. The format I'm capturing in seems to be in non-square format. Since my intent is to create files that I view on my devices, and never to go back to tape again, how should I, in the transcoding process, be addressing going to square pixels so the material doesn't look "squished"? Set the size at 640x480? I want to make sure these files are playable for as many years into the future as possible, so I want to make sure I get this right.
Secondly, I read about this "Quicktime Gamma Shift" thing, and it sounds like going directly to MP4 and skipping Quicktime as a wrapper is also advisable. But... as a Mac user, can I actually do that? Quicktime seems to take over everything! Should I even bother with this, or is there an app I should be using to transcode that would allow me to "skip" Quicktime?
