Any way to add transcoding options?

[BrettDioson 4]

The transcoding of videos with dark scenes isn’t very good by default (dark scenes have a lot of artifacts). Is there any way to add command line options for when files are transcoded? I see the crf and encode preset options in transcode but don’t see a way to add something like --aq-mode 3 as an option.

Is this hdr content?

no, its 8 bit.

 

sorry, i should have also said i have the Preset at “slower” and CRF at 20.

What is the source format and bitrate of the original files and what are your transcoding it to (resolution/bitrate)?

 

Could you provide a MediaInfo text file of one of the source media files with this issue?

[BrettDioson 4]

Actually the image issue may have been a graphics driver and config issue on my side.  my monitor is an HDR monitor but not a very good one apparently and was not playing nice with my NVidia drivers.  I just updated the drivers and turned off HDR and the artifacts are no longer there (or at least minimized).

 

Still, a command line option for adding arguments for ffmpeg when transcoding may be helpful in the future.

 

Here is the media info of one of the files I was playing:
