I have a Dazzle DVC 100 that I'm using to connect an old 8mm camcorder up to in an attempt to digitize all our home movies.
The videos are all NTSC SD I believe and I've had the best success at recording with FFmpeg.
I wonder about the video size and framerates as I want the ideal recording. Should the ratio be 720x480? From what I read 720x480 is NTSC DV but some others said it should be 640x480 (based on the pixels being square) or 720x486 NTSC SD.
Also is there any advantage in recording at a higher framerate? NTSC SD is 29.97 is it worth doubling the framerate to 59.94? The file size doubles due to the fact of recording two times the standard frames in a second. Is it just duplicating frames at that point and meaningless?
