These look great! It’s amazing how much better hardware gets annually. The only thing I was hoping for that wasn’t mentioned was hardware-accelerated VP9 encoding, but we can’t get everything we want in life.
For H.265 their encoder is fast, yes, but the quality per bitrate is complete rubbish, requiring higher bitrate than a good H.264 encode yet still contrives the gruesome trick of looking far worse, which entirely offsets all and any point with H.265.
