Overlaying Interlaced Graphics on Progressive Footage
on Dec 27, 2013 at 1:44:02 am

Hi, I have been working in CS6, rendering out footage re-converted to 576i or 1080i. My Video is progressive and I would like to use interlaced animation over the video. So my question is, is it ideal to render "upper fields" for the purposes of graphic animation on top of progressive video?

(for both video and graphics) Render settings: "Best Settings" > Fields: upper fields - for the purpose of graphics only

Lossless: Apple ProRess (LT) 720 by 576i PAL Widescreen 1.46 (16:9) D1/DV.

Once rendered the video its self is still "progressive" only the graphics are now "interlaced".

Please assist me in the right track if I am doing things wrong!

Yes, that would be fine (assuming you actually want interlaced output).

If you get to choose the format, you might also consider 720p50. It's all progressive, but has the same temporal resolution as 576i50/1080i50.

It may still be an option. 25p video is simply frame-doubled with 50p output -- not all that different than rendering it 50i with fields. The benefit is that you'd get the smoother motion for your graphics of 50i without having to deal with interlacing.
