I'm doing some experiments with HEVC x265.
I have a raw footage and the quality of details of h264 with same CRF setting looks better than h265.
Shouldn't be the opposite?
Maybe my setup isn't the best: I'm using ffmpeg for transcoding and vlc for review the videos, then i copy the screen content and compare the screens on a program like photoshop.
FFmpeg commands I using are the following:
ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv
ffmpeg -i input.mp4 -c:v libx265 -crf 30 -c:a copy output_h265.mkv
I used 30 as CRF for testing purposes because the artifacts are more visible :)
Could the loss of quality be caused by VLC and its experimental support in deconding h265? Maybe something more visible at lower bitrates?
