Hi Baptist,

thanks for all the updates in 7.1. Been testing with the new avcintra100 -target to convert Sony F5 XAVC
to an Avid compliant version AVC-INTRA100.

Converted Using;

ffmbc-10b -threads 2 -i SONY_F5.MXF -target avcintra100 INTRA_100.MOV

Will result in a file that is plays in Quicktime but is over contrast and is voor 90% in
error, with black en highcolor macroblocks. When we adding the -tff flag

ffmbc-10b -threads 2 -i SONY_F5.MXF -tff -target avcintra100 INTRA_100.MOV

the output is as expected.

Any ideas, test footage is available.

Yes, there is an issue with progressive encoding in x264 currently.
