[Mp4-tech] [Video] HDconfiguration

[Charles]

I am trying to ask the question "what is the required bittrate to send ok
720p HDTV compressed with H.264.
As long as you know there's no absolute answer for that.
Can we except HDTV material to be compressed with this config?
I think it's safe to say that no commercial content will be compressed using
the reference encoder.
Will it be relevant?
IMO, if you use the reference encoder (rather than the software and hardware
encoders that will be used to encode 720p to AVC), your results probably
won't have any practical relevance to non-academics.

Dear experts.
As my master thesis I am conducting a subjective video quality assessment
regarding H.264. I am trying to ask the question "what is the required
bittrate to send ok 720p HDTV compressed with H.264.
The setup is a DSCQStest with a high quality master and then h.264 sequences
with different bittrates starting from 20 Mb/s and going down. All on a
consumer display.
My questions to the list are:
1. Is the JM encoder_highquality_HD.cfg a good config for this test? Should
I make some adjustments? Can we except HDTV material to be compressed with
this config?
2. What do you think of the setup for the test? Anything wrong/right? Will
it be relevant?
Regards, Rasmus
