View Full Version : Is this max bitrate normal with both DTS and 5.1?

I'm doing Underworld as a part of batch processing of 3 movies in a row.

I keep both 5.1 eng and DTS

In the ECL file I see this from one of the main movie:

cbr_brate=6000
vbr_brate_avg=4168
vbr_brate_min=500
vbr_brate_max=9000

Isn't it a bit risky that the max bitrate is set to 9000 by default?

I use latest version of DVDRB and CCE 2.67

The max bitrate is calculated based upon the tracks you have selected. If it is higher than max_bitrate, it is set to max_bitrate (which defaults to 9000 but can be changes in the INI).

Remember that in DVD the maximum bitrate for the combination of video, audio, and subs is 10.08Mbs. Are you positive both are present in that specific VTS? AC3 5.1 uses 448Kbs and I think DTS uses 754Kbs...

Yes there are 2 audio tracks which those specifications.

I'm encoding on my labtop also, it also gives me a max of 9000

Could it be a small bug introduced in 0.84.1 ?

Maby you could test it yourself.

I changed the max bitrate to 8500 in the .ini file just to be safe
