How would one "test" the difference technically? Or measure the color information? and "by eye" I see no difference whatsoever. Update 1: I just did a quick test using 50mbps, GOP size 1, I-frames only. It would be great to see if someone has done some real-world testing. Or does H.264 just not have the color depth to compete? (E.g., only using "I" frames.)Īssuming H264 is a more "efficient" codec, we are hoping to get smaller file sizes. Say, with bitrates of 50-100mbps, and tweaking the GOP size/structure. We are wondering if it is possible to reach adequate quality with H.264. We use 422 as a delivery format to go to DCP for theatrical versions of trailers. Has anyone done or seen any tests comparing Apple ProRes 422 with high-bitrate H.264?
