i have a 30min project that looks great in final cut and it looks the same after compressor except in a few spots. in 4-5 random places for 3 or 4 seconds there are these pulsing 'hits' on the project. the audio is fine its just visual. there pulsing hits about twice a second and kind of looks like digitizing.

the project is going from 1080i60 to SD using the 90min 16:9 best quality selection. its not the kind of disc i'm using because i can see the same thing in DVDSP. any help would be appreciated. thank you.

If you're talking about dropped frames and or pixel noise, I've never seen these as a result of Compressor, they usually come from dirt on the camera heads during shooting or the capture process.

The only other possibility I can think of is that you didn't use the long way of exporting a movie. That is, export as a Quicktime then open it in Compressor.

Oh and if you didn't shoot it as 16:9 that could also be the problem.
