Nearing the filling of my 14.5TB hard drive and wanting to wait a bit longer before shelling out for a 60TB raid array, I’ve been trying to replace as many x264 releases in my collection with x265 releases of equivalent quality. While popular movies are usually available in x265, less popular ones and TV shows usually have fewer x265 options available, with low quality MeGusta encodes often being the only x265 option.
While x265 playback is more demanding than x264 playback, its compatibility is much closer to x264 than the new x266 codec. Is there a reason many release groups still opt for x264 over x265?
The way it was explained to me once is that the asic in the gpu makes assumptions that are baked in to the chip. It made sense because they can’t reasonably “hardcode” for every possible variation of input the chip will get.
The great thing though is if you’re transcoding you can use the gpu to do the decoding part which will work fine and free up more cpu for the encoding half.
