[Mp4-tech] [h264] coding parameters for HD

[Mauricio Alvarez]

Hi.
I am making some experiments on high definition video decoding using 
the JM-9.3 H.264 reference decoder.  For that I am coding some test HD 
sequences (1280x720) using the reference encoder.  My target application 
is HD video for playback reproduction like HD-DVD (or Blu-ray) and 
broadcast (satellite HDTV).
I am using the FRExt High profile with level 4.0. and I am defining the 
best encoding paramters for HD. In especial I want to know what can be a 
good frame period in terms of I, P and B frames.
In the bin directory of the JM software there is a file called 
encoder_highquality_HD.cfg that suggest the use of:
IntraPeriod    =  4
NumberBFrames  =  2
FrameSkip      =  2
That will generate a sequence like:
I-P-B-B-P-B-B-P-B-B-I-P-B-B-P-B-B-P-B-B...
Is this configuration adecuated for the mentioned HD applications?
Thanks for your attention
