In PP CS4, under H.264 output options, you could chose from 1080i and 1080p formats, but since I upgraded to CS5, the options in H.264 encoding only have 1080p formats listed. When I try to change things manually, I get a "invalid frame size/frame rate for this level" warning.
Why have they removed the option for H.264 1080i encoding?
When I edit my 1080i(50i) footage now I have to render in 1080p, and slow pans are horribly flickery, but they were silky smooth when I used to output in 1080i from CS4.
Is this right? Is it just my install of CS5 that doesn't have these options?
