BrettDioson 4 Posted February 26, 2019 Share Posted February 26, 2019 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.

Carlo 4332 Posted February 27, 2019 Share Posted February 27, 2019 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? Link to comment Share on other sites More sharing options...
BrettDioson 4 Posted February 27, 2019 Author Share Posted February 27, 2019 (edited) 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: Media Info Video Title720p HEVCCodecHEVCProfileMainLevel93Resolution1280x718Aspect ratio16:9AnamorphicNoInterlacedNoFramerate23.976Bitrate633 kbpsPixel formatyuv420pRef frames1 Audio TitleAAC stereo DefaultCodecAACProfileLCLayoutstereoChannels2 chBitrate192 kbpsSample rate48,000 HzDefaultYes Containermkv PathE:\Users\Public\Videos\TV Series Kids\Supergirl\Season 4\Supergirl - S04E07 - Rather the Fallen Angel.mkv Size191 MB Edited February 27, 2019 by BrettDioson Link to comment Share on other sites More sharing options...
