What is the difference between the 2 encoders?
The basic difference between the 2 encoders is that they use different Motion Estimation Algorithms. Because of this, the performance and quality is different for the 2 encoders. Also there is a difference in the number of resources being used by the encoders. 720p encoder uses 21 EDMA channels and 32 Kbytes of L2 as SRAM. 1080p30 encoder uses 49 EDMA channels and 64 Kbytes of L2 as SRAM.
