I think. > Your file is still 4K from what I can see. Seeing as the ffmpeg terminal outputs and the screenshots look identical in the source and new files, there seems to be something about how your (4k?) 65 inch TV is interpreting the file. As a long shot, I'd be curious to know if there's some flag in the reencoded h265 bitstream that is in your source file but not in the output,and this is what is triggering the issue. Can you try the following command and check it on your big TV? The encode should be very quick as the streams are being copied into a new container. ffmpeg -i "Wreck_It_Ralph_Full_Bluray.mkv" -c copy -map 0 -color_primaries bt2020 -color_trc smpte2084 -colorspace bt2020nc -color_range tv Wreck-It_Ralph_streamcopy.mkv _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
