View Full Version : CCE-SP VBR container bitrate too high, how do i change it?

ok, im sure its been well discussed but i was wondering if there was a way to turn down the container bitrate setting in cce sp 2.70 so i dont get that bitrate error message in tmpgenc dvd author 1.6 when i add the audio.

the cce mpeg2 dvd output container bitrate is preset at 9800 kbs when you select vbr, and even if you set the vbr limit at something lower, the container still has the bitrate upper limit set at 9800 even if your video never goes that high. this would be fine if that was the total bitrate for the video AND audio but when i add the audio to my authoring prog it throws back the bitrate error saying its too high for the total project. i know some progs recognize this and it doesnt matter, dvdauthor 1.6 doesnt.

i also already know i can just select normal mpeg 2 for output and not the "dvd" sub category but then i have to do a whole lot more tweaking in avisynth to get it dvd compliant, and id rather just have cce do all that stuff cause it does a much better job.

i see the option to lower the universal bitrate seetings in the "advanced" tap but every time i lower it and close out it just sets itself back to 9800. how can i lower the output vbr container upper bitrate limit WITHIN the "dvd" tempate?

if its not possible what dvd authoring prog should i switch too? its got to have a high stand alone compatability rate my dvd player is very old.

Hi-

Why switch to anything (if you like to use TDA)? It's just a well known bug in TDA and doesn't affect anything. Any other authoring app will also keep that 9800 figure, but just won't warn you. Go ahead and author and you'll be fine. Assuming you didn't really set the max bitrate too high for the audio, subs, and overhead, the result will be compliant and play in your player. Have you ever checked the max bitrate in retail DVDs? About 90% of them also say 9800, even though it's obviously much less.

That 9800 figure is just a number in a header and doesn't have anything to do with anything. No authoring app can know that you went over until it does the actual authoring and you get buffer underflows.

You can change that 9800 to anything you like in ReStream.

Or, uncheck the "For DVD" box in CCE, and then it will show the actual bitrate you set.

No, AviSynth does a better job. If you set up your scripts properly, you don't need that box checked.

it takes way less time if i have cce do all the dvd compatibility stuff, even when using fitcd.

i cant remember now and im away from my editing computer but i think that it wont let me author, it gives me the error message and then wont proceed.

but your right, i just need a to find a way to alter the max bitrate limit in the header.

i swear there has got to be a way to lower it in cce-sp. in the advanced tab that stuff seemed like those were the settings for it, i just cant figure out how to work them because im new to cce.

what authoring prog would you suggest? its probably time i switched anyway, dvd author is very basic.

Not true.

Turn off "For DVD". You know, you could try reading the manual:
In DVD mode, when you select VBR, 9,800 kbps is always written as maximum bitrate in the sequence header of output MPEG files whatever value you may set. It is for more flexible bit allocation to achieve higher quality. However, some authoring softwares seem to calculate the bitrate for a DVD using this 9,800 kbps as video bitrate. And when multiplexing with PCM audio, they consider the total bitrate out of DVD acceptable range 10.08 Mbps. If your authoring software has this problem, please choose MPEG-2 mode. Then the maximum bitrate in the sequence header will be the value you specified. Note that actual bitrate does not exceed your maximum bitrate setting even if 9,800 kbps is written in the sequence header.
what authoring prog would you suggest?
Use whatever you like. I'm just saying this is a non-issue.
