D1 NTSC frame size / 29.97fps / 30fps render setup ?
Hi all,
I’ve been asked to render some work for a client in Korea. As I normally work in good old PAL i’d just like to confirm somethings before I render. I will be outputting to 720×486 / 29.97fps
PIXEL ASPECT:
When working in PAL i usually work in square pix (768×576) then drop that comp into a non-square (720×576) comp to output. AE handles this without needing to manually scale.
I tried dropping an NTSC sq pix comp (720×540) into the non-square (720×486) and see that I need to manually scale to 90%. Is this the correct method?
FRAME RATE:
29.97fps ?? I’m aware there’s something called drop-frame and non-drop frame, but have never needed to deal with it. In C4D should I set my render frame rate to 30fps or the arbitrary 29.97fps. Anything to watch out for on import ?
Any help would be most appreciated.
Cheers,
Andy -

Welcome to the world of NTSC. You can render at 720×486 with a .9 to 1 pixel aspect ratio and not worry about the re-sizing issue. As far as 29.97, I wouldn’t worry about that unless you are doing several minutes of animation synced to sound. Actually I recommend 60 fps and on your final ae field render use 29.97. Its always a good idea to avoid fields until the last pass.

Dunno what’s going on, but should work without scaling. I’m no NTSC expert, though, as usually we do not do native NTSC projects, we are just converting footage on an as-needed basis.

I wouldn’t bother with non-drop. This is more or less a minor technicality not really relevant for 3D and compositing work. Just render out 30 fps/ 60 fps and you’ll be fine.
