Hello,
I encode an ProRes422(HQ) file to H264 422 10bit in two pass
with those commands:
ffmpeg -y -i /Volumes/HyperFS1/file.mov -flags +ildct \
-c:v libx264 -vprofile high422 -level 4.1 -tune:v film -preset:v slow  -b:v
25000k  \
-x264opts "ref=2:keyint=27:min-keyint=1:slices=1:b_pyramid=0" -pass 1 \
-filter_complex "[0:0] [0:1] amerge" -c:a libfdk_aac -b:a 320k -ar:a 48k \
-f mp4 /dev/null && \

the command for pass 2 is strictly identical except : -pass 2 and output to
/Volumes/HyperFS1/file.mp4

Here the consol output : pastebin.com/4xzTfKhF
I then send the file to a Baton QC account.

Here the output : pastebin.com/UTMyGzfc

It seems there is an error on pic_init_qs_minus26 value in PPS.

I really dont' know wich  are the parameter that influence this.
Any help will be really welcome.

Julien Daniel
