I forgot where I found this information. I test it and it work.

"Just a quick comment, typically if one has the ability to purchase Quick Time Pro the best render settings are by far using the two programs together. A setting that found that works amazing is to render out your comp as a RAW uncompressed animation from AE using the .mov and animation uncompressed. From there, you can just open the file in quicktime and export from quicktime using the .mp4 with H.264 @ 7000-10,000 kbps and it will still play a 1080p video file without any loss in quality. The power in this is your very first export from after effects as a raw animation will be huge, but Quick Time will make it very small and even able to email as a 1080p video. An example from today, rendered out a raw animation from AE and the .mov file was 2.8GB. Once compressed it in Quicktime Pro using the settings mentioned above gave me a file size of 15MB and the file was 1080p with very very little quality changes."
