Recompressing 1080p h264 collection to HEVC - Target Bitrate For Minimal Loss
I've transcoded some of my AVC (h.264) 1080p movies to HEVC (h.265) with 2 pass encoding (using my GPU) and target bitrate set to 50% of original. The other streams (like audio and subtitles) were only copied into the new file.
Mostly I'm using Potplayer to play these files with Madshi renderer, and I can't see any difference on a 55&quot; 4k HDR TV with naked eye. The only thing, that I've noticed at some movies, if there are dark scenes with big black backgrounds, the transition from one shade of black (dark grey) to another is built from much more bigger blocks in HEVC, like in AVC version. I say again, these blocks are visible both on AVC and HEVC but only in some of the movies and in HEVC they are a little bit more noticeable.
But I'm only a home user, I'm not making professional videos and the 15GB video file vs the 30GB worth it to me.
