Why can I set the Movie bitrate Manually in BD Rebuilder ?

Why can I set the Movie bitrate Manually in BD Rebuilder ?
thx BD Rebuilder has to set the bitrate so that the output will fit on the selected destination. If the bitrate can be adjusted, it will screw up the sizing. Allowing it to be set is just an opportunity for self-inflicted injury that will be reported as bugs by those who really don't understand what they're doing.

At some point in the future I will probably add features like I have on DVD Rebuilder in which you can adjust the rate (within boundaries dictated by size of the extras) and the changes will be "stolen" from the extras. But that's not something that's going to happen anytime soon.

I can see how this may be complicated to implement, especially in an 'idiot-proof' way. If I can make a suggestion, perhaps a slider that allows for reasonable values could save people from themselves (or a popup that warns you that you are setting yourself up for oversize if manual entry is allowed), if and when you ever decide to implement such a feature.

Great work on this tool by the way, we appreciate the strides you have made and are making!

ok, also , when encode I Full Blu-Ray with example 32000BitRate with MODE Movie-Only , Custom Target size 24000MB , Encoder settings VERY SLOW, .. outcome Blu-Ray size is 19GB with 25000 BitRate !!! Because BD Rebuilder has anywhere fix set max Bitrate 25000!!! I want to use whole size of Blu-Ray DISK 23GB !!

If you're encoding at 25000 Kbs you don't need any more size. It isn't going to get any better in terms of quality, and that's the only reason for filling up a disc... that is a very, very high bitrate. In fact, if you are doing a full backup, I have a difficult time believing that you are getting a rate that high.

By the way, MAXRATE is never set to 25000 on a BD-25 or higher. It is set to 35000 for very some good reasons. The MAXRATE also will not normally limit your output size, that would be a result of the specified average bitrate.

I'm a little confused by your note, though. In one place you say your bitrate is 25000 and in another you talk about MAXRATE which are two very distinctly different things.

latest BR Disk encoded with BR Rebuilder

Original Disk size with 1x audio : 29GB/ 32000 BitRate

Encoded with 1x Audio
Bit rate : 20.1 Mbps
File size : 19.3 GiB

the same settings
MODE Movie-Only , Custom Target size 24000MB , Encoder settings VERY SLOW

Why, as little BitRate & Size?!

"max" = I think of Maximum, no Maxrate

why receive I NO 1xEncoded Disk with bigger BitRate as 25000?

never a one disk had not bigger BitRate as 25000!

and where from teke Rebuilder x264 settings? who it is defined?

[Eisy]

or, when I will e.g. outcoming Size 24000MB wit 28000BitRate Movie only + 1xAudio AC3 640Birate , how have I SET the BD-Rebuilder?

(orig disk- e.g. :movie+1x audio hat 30GB with 34000Bit-rate)

and where from teke Rebuilder x264 settings? who it is defined? That's different. I limit the average bitrate to 25000 so there is some movement of available bandwith between the 25000 and 35000 (MAX). If I set them both the same it's pretty much a bad way of doing CBR.

You are not going to get a better picture by going above 25000 -- again I say that it is very rare that you can reencode a full backup and ever, every have a rate that gets that high. That's only a little over two hours of video.
