[FFmpeg-user] EVS compatible AVC Intra 100

Thanks for the answers.


I didn't paste the output because I did not get any error. I already checked with EVS and just wanted to make sure I got the "standard"AVC Intra 100 parameters right and that I was not making any mistake before getting back to them.


Erik, the mxf was one of my suspicions as well, that's why I rewrapped the file with bmxtranswrap so I could get v1.3 instead of 1.2.


This is the output I'm getting, all seems ok to me.

In principle if you guys can confirm me that nothing looks weird in my command line for an AVC Intra 100 transcode that would be great so I can check back with EVS more confidently :)

Thanks,
Victor

Also, ffmpeg is/used to be not very good at writing op-atom, I've had
better results using the bmxtools or ffmbc if you want to avoid batch
processing a single file with multiple tools.
