I've been asked to create HD MPEGs based on the following dimensions:
Pixel Dimensions: 1920 x 1080
Frame Rate: 25fps
Bitrate: 36 mbit/s CBR
VBV Buffer Size: 488
N Value (Number of Frames in GOP): 15
M Value (Number of Frames Between Anchor Frames): 3
Sequence Header Interval: Each GOP
Video Encode PID: 16
If you look at the settings, Compressor (as far as I know) cannot achieve this. For example, If I choose the MPEG-2 or the HD MPEG presets and then try to adjust these (after duplication), I cannot change the bitrate settings from VBR to CBR as an example.
Would be grateful if another encoding application can be recommended for the apple mac (does Pixel Tools have a mac version of their MPEG encoding software for example?).
Somehow I could do this...I don't recall what I did. I think it depends on which preset you start with, duplicate it and then adjust the settings. I had to make a similar MPEG and at first I could not change the VBR setting.....later I tried again and I could select CBR no problem.
Again it depends on which preset you start with (can't recall) and how you change the settings.
You are probably going to have to invest in another program. I'm sure episode will do this but does episode do hd..? I use Rhozet which is a pc program, you can pretty much make anything m2t's to flash etc, sound like you need a transport stream because of the pid but there is also a need for a audio program id..
