The encoder should support all bitrates at 1080i/p 8 bit depth. 720p is under development.
Encoder is multithreaded and should be real time on quad core cpus, quality should be better than what avid media composer produces (observed during the tests by the author).
Email the author if you find any files that crashes the codec. The address can be found here:
