Reported by daniel.p...@studiodigit.co.uk, Oct 16, 2012
What steps will reproduce the problem?
1. ffmbc -i "xxx_576p24.avs" -threads 4 -vcodec prores -profile hq -intra -aspect 16:9 -acodec copy xxx_576p24.mov
2. Attempt to import file into Cinema tools for conform to 24p


Cinematools believs there is temporal compression in file - it states quality good (temporal compression) where a file created from compressor/fcp states quality high, and allows the fcp fiel to be conformed. Cinema tools only works with i-frame based codecs. 


version: 0.7 rc 7

Hi. I want also add for this issue. I am having same problems with FFmbc version 0.7-rc7.

I am using this line:
ffmbc -threads 8 -i IN -an -sws_flags bicubic -vf scale=1024:576 -aspect 16:9 -vcodec prores -profile std -pix_fmt yuv422p10le OUTPUT

Cinema tools cannot confirm this file (i need to confirm it to 25fps) - confirm button is grayed out. In Analysis tab of Cinema Tools theres such info: Compressor - prores, Quality - Normal with temporal.

ProRes files produced with FCP works fine with Cinema Tools and I can comfirm them to 25fps with no problem. If I open files from FCP in Cinema tools Analysis says the following: Compressor - AppleProRes 422, Quality - Maximum.
