Hi Chris…
Yes, shooting 16:9 on a Canon XH A1s and Canon 7D … I’m 1440 x 1080. I’ll try the 4:3… last year when I was 720 x 480 anomorphic that worked.
Here’s my sequence setting, clip based
Time Base: 29.97fps
Frame Rate: 1440 x 1080 (16:9)
Field Dominance set to none <— note sure if this is right given I have mixed media
QuickTime Compressor setting: 422 (LT)
Thanks
Frank
