Very well. Professional encoders suck, then.
Why? Blu-ray still produces the highest quality video in the home today.
A common problem with comparing still images with a perceptually lossless codec is the encoded frame type. If one codec happens to be an I frame and the other a B frame, is it fair? Bs are quantized higher than other frame types to save bits. Visually they will look worse.
The trick to compression is you are supposed to watch it playing in realtime.
A-titles are getting lower bitrates than smaller films because of extras. Disney, for example, will use an average rate of 20 Mbps with a peak of 30 Mbps for the video. The lossless audio and PiP and extras are taking up the rest.
Sorry for going off topic. I really enjoyed the reel. It does show that I have a long way to go in producing better images.
