Doom9's Forum - View Single Post - How much lower of a bit rate on h.265 will give similar quality to h.264?

Depends on the type of content in the lossless avi files. anime (big areas of colors sharp edges etc) is different than pixel art games (side scrollers and mario like games or games like stardew valley , starbound, terraria etc) game capture and different than multiplayer games with lots of action and motion and different again than movies with grain and slightly blurring which helps with compression.
I would say that 20-30% less bitrate for same quality would be realistic, if you use software encoding (like finely configured x265, configured for the type of content you wish to encode) . If you use hardware encoding (new RX series and GTX10** cards have hardware HEVC encoders) won't compare in quality with software encoders.
