Looks like it didn't get enough bitrate. Looking at the file metadata, it has a crf of 18 (which normally would be good enough for any resolution), but also a cap on bitrate to 1300kbps (vbv_maxrate=1300), which would destroy the video quality, considering you have a 4k video to encode.
@alyx I guess I need to tweak this
@matrix
My suggestion would be to add a resize, limit the resolution. Otherwise, you'd need to increase the bitrate by too much to get good results, and that would have consequences on encoding time and bandwidth usage.
@alyx Yeah, adding a resize for video that's over some size is going to be difficult, but I agree that's the best option.
