anamorphic comp dimensions?
Sorry – simple question. Cannot seem to find the answer via a search; I have tried.
I am doing some comps for a project that is in SD anamorphic, 720 x 486 (using blackmagic uncompessed 10 bit codec). What are the proper pixel dimensions of the comp in aftereffects?
Thanks,
jason

There’s 2 presets for this. NTSC Widescreen which is 720×486 with a 1.2 pixel aspect ratio and NTSC Widescreen Square Pixel which is 864 x 486 with a 1.0 par

Much obliged.

i always work at 864 X 480 (or 486) so that the scan lines of any imported video don’t get reinterpreted. this keeps the image cleaner if there is video involved in the comp that has not been scaled down. Never liked working at 720 X 540 because of the scaling scan lines problem

scaling scan lines: it sounds like a problem I recently ran into. I imported some video into AE and rendered and imported back into Avid. There were noticeable scan lines. Not the ‘interpret footage’ kind. I couldn’t figure it out. Could it be because I was working in a 720×540 comp? My work around was to re-render as a photoshop sequence (thus eliminating scan lines).

This was helpful to me. I’m creating a video for Filipino TV and the footage on my timeline is a mashup of lots of footage. Should I render upper/lower field first or progressive scan?
