I have seen this question brought up before but not answered fully.
i need to make a video that is
File format: MP4 H.264
Aspect Ratio: 16 x 9 (1920 x 1080)
NTSC HD 60i (interlaced)
24 bit stereo
When exporting i selected H.264 Blue Ray and set the video accordingly (set the resolution to 1920 x 1080 @ 29.97, upper, square pixle) the problem I’m having is setting up the audio to be 24 bit. From my understanding AC3 only supports 16 bit but what about Dolby Digital can i get 24 bit audio if i use it and what setting do i change to get 24 bit audio at 48 kHz?
