digitizing from an analouge source
I’m sorry if this has been covered before. I tried to think of what terms would bring this up in a search, and I failed to find anything. I am capturing video from a Betamax deck, and I have used several different hardware and software solutions to do so. I started using the ADS Pro A/V link (I wish I had the money for something professional, but it seems to work well enough). However, I stopped working on the project for a bit and I misplaced it so I digitized some footage though my Sony Z1U. I have used a few different programs too. The point is that I now have clips in 3 different sizes despite the source being NTSC 4X3. Opening the files in Quicktime from the finder, I see some files are 640 X 480, some are 720 X 480 and the ones digitized though my Z1U are 853 x 480 and obviously stretched, though they all look ok in FCP.
1. should this matter? I am capturing this to put to DVD, but also to preserve the video to the best of my ability.
2. IF it matters, should I re-capture it and what size would be optimal?Thanks,

It probably won’t matter too much. The best and proper size is 720×480. 640×480 is square pixels for computer monitors to show the movie properly and used to be what old video cards would capture at. (As a side note, Quicktime sometimes converts the footage to 640×480 to show it to you properly. It should tell you, though, if it has been converted in the info palette.) The 853 is an anamorphic image, which you noticed.
As you also noticed, Final Cut knows what to do with these sizes by either scaling them up slightly and/or distorting them so they show properly.DVDs and DV footage is 720×480, though, so if you have one that captures at this setting, that would be the one to go with.

the problem is now I can’t even recall what app created it in 720 by 480.
I also just noticed, while looking for the creator, the frame rate is off too.
in the 640 files it’s 23.81 while the 720 is 29.1 (according to quicktime’s info window)—————
