Re: Compressor: .mp4 file H264/AAC optimized both for RTMP and HTTP streaming ?

[Paul Sellis] "do you recommend me to use MainConcept or x264 ?"

Both are better than Apple's H.264. To take best advantage of x264 can require some "under the hood" encoding knowledge to tweak settings. Even using its defaults can get great results and if you want to stick with Compressor you can use x264 with it.

MainConcept, tied to the professional front end encoders such as Episode or Squeeze is a bit easier to use and you get an app that is far more flexible and deep than Compressor along with it.

Any of the above is better than Apple's H264 and even more so at lower bit rates which may be obvious down around 700kbps.
