I have a copy of the following (severely lacking) specs from my local TV station:
Container: Quicktime movie
Frame rate: 29.97
Codec: H.264 (limit data rate to 25 or 50 Mbps (24414 kbits/sec)
Acceptable frame sizes: 1920x1080, 1280x1080, 1440x1080
Audio: uncompressed (.aiff) 48 kHz 24-bit
AUDIO PEAK LEVEL MUST NOT EXCEED -12 dB
QUESTIONS
==========
(1) QT doesn't provide an H.264 format --- use MPEG-4 Video here?
(2) The QT audio tab only provides a bit depth of 16. ???
(3) Do I limit the data rate to 25 or 50? Which is it, guys? Come on!!
(4) PEAK LEVEL MUST NOT EXCEED -12 dB? What!?
I contacted the station "tech" guy and he's kinda clueless. He told me to disregard the peak level requirement, which speaks pretty poorly of their so-called specs...
So, how do I get 24-bit audio into a QT file? And, perhaps, this can be disregarded as well... but why is there no 24-bit option? And if I select the audio format "24-bit Integer" there STILL isn't a 24-bit option! Which leads me to believe only 16-bits are making it into the final output.
Further, if I go with 24-bit Integer, then I get to select Big Endian or Little Endian---since they are a Mac shop, I believe Big Endian is appropriate, no?
Any advice from anyone who has produced a TV broadcast spot? Is there a better external render method I should use (like the DNxHD workflow, which ALSO doesn't have a 24-bit audio selection)? I don't think Handbrake can help with this one.
Much thanks!
