How Much Does Compression Affect RB Processing Time?

[TomBrooklyn]

How much does the amount of compression required affect the amount of time it takes RBPro to encode (transcode?) a project?

Does it matter much?

Is RBPro much faster if there is no compression required?

I've never used it for a project without compression.

I just got some double layer disks and would be able to do some movie backups without compression. (I'm guessing RBPro can do double layer backups.)

There is no point at all to use DVD-RB for such purpose. You just need a decrypter to rip the DVD - RipIt4Me recommended. Then you are ready to burn - ImgBurn recommended. With suitable apps (e.g. AnyDvd, to decrypt on the fly) the DVD backup can be even performed directly disc to disc...

RB doesnt compress, it doesnt rip and it doesnt burn. All it does is provide an GUI for all the other programs.

If you dont want compression then just rip and burn

All it does is provide an GUI for all the other programsThat statement couldn't be further from the truth and shows little understanding of the processes involved. Try doing what DVD-RB does with just an encoder or the tools that are included. For one thing DVD-RB does the complete authoring of the new DVD after encoding. It does, in fact, do pretty much everything except the decoding and encoding. AVISYNTH/DGDECODE and the selected encoder does that.

Normally the lower the compression level the longer it will take. But this is only true if the size off all other stuff, sub/audio streams, VIDEO_TS.VOB and menus (if you don't encode them of course) is comparable.
The key value is the total number of frames to be processed.

Does it matter much?
See above. ;)
An example: You have a 90 minutes movie with a huge dts audio stream which you want to keep and a compression level around 50 %. On the other hand you have a 180 minutes movie with an ac3 audio stream and RB shows a 60 % reduction level after prepare. The short one will run much faster as the number of frames to be processed is much lower. :)

Is RBPro much faster if there is no compression required?Yes it is, as the video parts will not be feeded to an encoder and this is the limiting factor.

I just got some double layer disks and would be able to do some movie backups without compression. (I'm guessing RBPro can do double layer backups.)
I have to agree with Sir Didymus, if you just want to make a backup on a double layer disk without any changes there's no need to use RB at all.
Keep in mind that it needs time to divide your movie into segments and build the d2v files during prepare, build the m2v files during encode and remux them during rebuild.
This all is unnecessary if you don't want to change anything. ;)

Ahh, I see. I was barking up the wrong tree. Cheers.
