Why does the comparison use x265 instead of the reference HEVC encoder? Fabrice Bellard recommends that as it produces better quality encodes at the expense of CPU time.
I'm interested in seeing the result of using 4:4:4 with BPG. If you have the originals to compress, of course (meaning, the original is not chroma subsampled).
- xooyoozoo 12y agoHe either made his judgement based on non-obvious criteria or, more likely, looked at x265 at the "wrong" moment. Right before libbpg was announced, x265 had several commits fixing large 10bit and 422/444 bugs. As far as intra-prediction goes, x265 should be better than the HM by at least a few percents MSE-wise and around 10% SSIM-wise[0].
