*Inter P: all partitions (from 16×16 down to 4×4)
*Inter B: partitions from 16×16 down to 8×8 (including skip/direct)
*Ratecontrol: optional VBV, single or multipass ABR, constant quantizer
*Scene cut detection
*Adaptive B-frame placement
*B-frames as references / arbitrary frame order
*8×8 and 4×4 adaptive spatial transform
*Lossless mode

*Parallel encoding of multiple slices

Note: x264 is still in early development stage
