Hello,
I am on a Windows laptop with intel ivybridge HD4000 iGPU, hardware encoding with h264_qsv doesn’t work since it supports only skylake and above. I can however use h264_mf to encode videos without problems with
h264_mf under Codec tab
and under Other tab I use the following,
hw_encoding=1
quality=-1
rate_control=quality
scenario=archive
Except there is no control over encoding profile, main, base, high etc… I notice that in the view log there is a line
MF_MT_MPEG2_PROFILE=66
which means it encodes videos with constrained base profile, is there a way to set
MF_MT_MPEG2_PROFILE=100, which corresponds to encoding with high profile?
Thanks.
What does MPEG-2 profile have to do with H.264? You should be able to control the profile using vprofile=high. But I suspect the quality of this early generation H.264 hardware encoder is not very good and suggest to just use x264 instead.

Thank you. I tried vprofile=high before posting but it was of no use. The log showed this
[h264_mf @ 000002550f483c00] [Eval @ 000000840a5fec90] Undefined constant or missing '(' in 'high'
[h264_mf @ 000002550f483c00] Unable to parse option value "high"
and the videos were still encoded with constrained baseline profile. My use case on this old laptop is for initial fast editing, so export speed is more important than quality. I have a desktop for exporting in libx264 for final archiving.
The mpeg-2 line I quoted above came from the full log, part of which looks like this,

So it seems to me that profile setting is hardcoded and from the shotcut gui I have no idea of how to set the profile to high.
Also, ffmpeg does not have a param named ‘profile’ for h264_mf, I am not sure if this is related. The mpeg-2 line in the log may be due to low level interaction between intel graphics driver and ffmpeg?
