How Do I Burn Above The Max Bit-Rate Of 26Mbps

Question

Howdy, I've just purchased my first blu-ray drive from OWC and purchased the fabulous Toast 11 with the blu-ray plug-in.

 

I noticed that the maximum bit-rate option for authoring blu-ray discs is 26mbps:

However, I notice that commercial movies typically play at a max of around 32mbps as I've seen with The Avengers and Prometheus.

 

Is there a way to go beyond 26mbps or another piece of software that'll do that?

 

thanks.

The 26 mbps is for the video stream only. There also is the audio stream that is probably why you see a greater bit rate on those discs.

Thanks for helping but I'm afraid I don't understand.

 

Yes, you're right, that the bit-rate in my screenshot maxes out at 26mbps and that it's only the video component. Although the audio portion maxes out at 448kbps so the total bit-rate is still far below the blu-ray specifications:

Also, when I view the the home movie I burned on my PS3, the bit-rate shows (from pressing "select" during the video) that it maxes out at 26mbps as well.

Regardless, the settings available in Toast is the limit that Toast's encoder can produce. Note that PCM is an option for audio and that isn't compressed. Maybe Roxio allowed room for it.

That's too bad. Do you know of another piece of authoring software that'll go higher?

 

Also, I'm new to this forum. Do you know if the Toast dev team reads these posts regularly? ...or if not, how to go about submitting requests?

 

thanks again

It could be this is a safety spec necessary because various manufacturers of Blu-Ray players are producing machines that can't read data at the maximum bit rate. This was/is a common issue with sd dvd's which are typically recorded at 7.5 mbs or lower. People screamed bloody murder over burn failures blaming software, hardware and media before testing indicated specific brands and models of players were the big problem. Everyone eventually learned to keep the bit rates at safe levels so where ever your dvd's ended up they stood a good chance of playing smoothly.

 

Most pro authoring programs allow specification of gop structure, allocation of IPB frames and orders and adjustable bit rates above safe levels.
