on Feb 11, 2010 at 3:13:02 pm

Hi all. I'm in big trouble with Compressor. I'm trying to export a movie in MPEG2.

I'm using high resolution settings but my videos have an high level of compression, border of sharp objects appear with a lot of aliasing and on dissolve the video flicker.

Someone Can help me?

I post here my settings:
Mpeg2 1920*1080 29.97fps progressive
Teo pass VBR , Best
Average Bit Rate: 30 Mbps
Maximum Bit Rate: 40 Mbps

[francesco glavina] "1920*1080 (HDTV 11080i 16:9)30fps "no compression" progressive "

that makes no sense:

Is it interlaced or progressive?

This is likely where all your problems lie. Is your source interlaced and then you are exporting from FCP as progressive, or what?
