Thanks, that what I’d imagined. But, 720×480 or 640×480? If I have it in 720, I’d have side letterboxes on my 640×480 footage (which by the way are security cams).
The other thing is: If I shot some music on HD 720p24fps, how could I avoid any sync problem, in this final sequence (dv/ntsc, 640×480, 29.97 fps)?
Thanks in advance,
Ricardo Spencer
