H.264 maximum bitrate
Hi, I have been given settings to encode a video for adstream delivery here in Aus, that requires the bitrate to be 15,000 kbps or higher for a h.264 output. I use the following settings, but cannot get an output that’s more than 10.9 mbps. Any help? Does QT have a maximum bitrate for h.264??
settings:
h.264
framerate: 25fps
keyframes: all
best quality: multipass
data rate: restrict to; 25000 kbpssound: 48/16

I believe it depends on your h264 profile. The profiles have a maximum dimension and I’d guess the same is limited in regards to bit-rate.
Although I’ve not seen this setting accessible anywhere else than with Matrox Max settings that I use in Compressor. Maybe Episode Pro could get you there as well.

I just delivered to Comcast with H.264 15,000kbits High Profile from Episode Pro.
Compressor 4 can do H.264 .mp4 up to 30,000kbits although Main Profile, not High. There’s no High Profile option in Compressor.
Matrox MAX can target 50,000kbits.
