If I do it like this I assume that only angle 1 will be used, right?

The thing with this Star Wars box is that if I choose swedish for subtitles (during play back) the text in the intro will be in swedish. You know "In a galaxy far...."

Well I don't get it at all... How would you for example set the KVCD-Notch matrix in DVD-RB using FreeEnc? or 2pass mode? or GOP length?
there are no switches for that in DVD-RB, so how would FreeEnc know how to encode? even using QuEnc, there's no way to specify the GOP length...
and how about scene change detection?
Is anyone here actually using DVD-RB with FreeEnc? Please report, as I'd really like to figure this out!

Edit: Maybe Vinicus can help here too... how is FreeEnc supposed to work with DVD-RB as a substitute for QuEnc?

My first try: Disney's Treasure Planet.
I managed to make everything work.
I used Undot().Deen() as advised.
I got a Q=23 for main movie, and up to 124 ( ) for an extra...

My doubts:
- How does (if it does) DVD-RB resize the video?. Since in the generated avs thre's no resize nor crop (just a letterbox I added).
- What's the better way to encode menus and extras with less resolution?. In DVD-RB there's a check to encode half size, is it a good way?. I also thought I could tweak the avs for main movie with crop, or resize to make 16:9 -> 4:3; and tweak avs for menu and extras to make it halfDVD.

What do you think?. I found Q=124 too high (in fact is very blocky when previewing in media player).

It does not. Except for the extra if you chose "half space and half size for extra". Then a simple "BilinearResize(352,576)" is added ate the end of the script.

Yes but it does not affect menus. Menus are never changed by DVD-RB.

You can use Gripcrop/Gripborder insteed (or in more) of undot().deen()

It's very strange to obtain such Q. Do you use "steal space from extras" ?

And how does DVD-RB "know" what is it a extra or a menu or the main film (OK, main film will be the bigger one, what about menu and extras)

Hmmm. Can we tweak the avs with RBopt, to filter more and resize?.

No, I don't. It's a very short clip. Maybe prediction failed due to selection of complex scenes by chance. Can't tell you...

The movie is the longer PGC (generally isolated in a single VTS). That is how all tool identify it (try DVDDecrypter in file mode and ask it to select the main movie). All other IFO/VOB files taht are not from this VTS are treated as extra. The Menu is (always ?) in VIDEO_TS.ifo and VIDEO_TS.vob.

You are asking for the menu ? NO ! DVD-RB does not treat them, it simply copy the file "as it" from the source directory to the target one !

For extra ? yes

Or due to shortness of the clip.
But for your information, we never use OPV prediction of DVD-RB, we use the one of RB-OPT. DO you know it ? DO you do that ?
(in last RB-OPT there is a checkbox "allows OPV even for short clip" that is unchecked by default, that means than short clip must be done in VBR mode I guess).

I completed my first rebuilding... not bad. 7 hours (it took me some time to redesign the avs: I used a simple one for the film, and MA with resizing to 352x576 for extras). A little oversized (4500 Mb). Looks nice. Problem: I resized extras from 16:9 to 4:3 352x576, but some extras were already 4:3... and they look horizontally stretched . And some selectable items are out of their place, due to resizing (I could live with it, but I'd rather fix it...).

OK. My problem is, since I want to keep as much space as possible for film, that DVD-RB seems to divide equally space between film and extras. And then?: I got a Q=23 for film and Q between 3 ( ) and 15 for extras... That I don't want. I prefer Q=30-35 for extras, and leave room for film to be encoded with maximum quality possible. To me it doesn't make sense to have high quality extras (Q=5, even at 352x576, looks WOW).

Yes, thanx, I do. And I also join vobs, tweak CCE (DC precission to 9, GOP 15,...)...

So my main problem now is to be able to adjust DVD-RB to encode extras with less quality to leave more megas the film to get better quality. Maybe I could try in DVD-RB the Leave less space for extras (or something like that) check, where you can choose between 25%, 33% and 50% reduction. As I'm resizing to 352x576, I'm sure I'll still get a good Q (buff, 3 was too much). What do you think "rebuilders"?.

First, DVD-RB does not divide equally, it divides proportionally. If extras use 30% of the original space, then they will occupy 30% of the final encode.
Second, you have to way to stole space from extra (and give it to movie) :
- menu "Mode" -> "Steal space from extra" -> set from 25 to 50%
- menu "Mode" -> Half space and Half size for extra. That is the same as 50% above but the extra are all resize to half resolution (352*576)

-> do not use the two settings at the same time or the extra will be unwatchable.

If you use RB-OPT you can also try to fix manually a Q value for extras and let RB-OPT compute the one for main movie only. It's just an idea, I don't know if this can work.

One thing that would be very useful especially with any TV-series DVDs would be the ability to divide the bitrate by the complexity of the material. I do this all the time for all my manual encodes with 2-3 movies per DVD-R.

I encode a 1% sample clip of every title with the regular script plus SelectRangeEvery(1500,15) at the end, determine the average bitrate and use a spreadsheet I've created to get the weighted average bitrates for each title.

I'll try this way. But I'm afraid that, as DVD-RB calculated first the available space for main movie and extras, RBOpt won't "redistribute" (correct english?) the free space available after encoding extras at a higher Q value, but will find the Q necessary to fit the movie in the space DVD-RB calculated first. Does it sound OK?. But, of course, it's better to test and see what happens. I'll also try the steel space switch, but to me looks too "fixed", I mean: 25, 33 or 50%.

Well, I think you know that I don't ask questions knowing the answer. I have a doubt, and think of a possible way to solve it. But I ask to see if more experienced people agree with my solution, or can offer a better solution (that is what usually happens ).
Thanx for your help
Boulder, your method sounds nice. Of course, you encode both samples with same Q to be comparable. It would be necessary to implement in DVD-RB a method to divide the space in a similar way as it does DVDshrink, where you can choose the percentage each part of DVD will be shrinked.

I think you shouldn't use Steal Space From Extras together with RB-Opt

Boulder, sorry, I'm sure the answer is obvious, but I can't see it right now...
Why?

From RB-Opt's readme:

Code:
Hint: Please, don't use the "Steal Space From Extras" Option introduced in DVD-RB 0.52 if you plan to change bitrate with RB-Opt. Using this option, you'll have a wrong reduction % displayed.

That is exactly what I'm not sure this can work.

Personally I do anything with "Half size and half space" and I'm happy with that.

RB-OPT let you do that. You have tu uncheck the box "autosize" and mode the slider.

I'll try with it. Do you also use RBOpt?, I think I understood yes, you do. I ask because of Boulder comment (BTW, thanx Boulder for the info). But as there isn't really any problem with using steal space together with RBOpt (just wrong info displayed) I guess there's no problem to use them together.

...GREAT (sorry me for shouting). I didn't know this option. It is very nice. I've been playing with it: you can give the movie a bigger percentage (you see the avg bitrate raising) and automatically it seems to steal space from extras equally (when you change to extras VTS, you see that percentage decreased and also avg bitrate). I'm willing to play with this option and see the output.
Thanks for the feedback

I need your help here guys...
Everytime DVD-RB is encoding a new cell I have to enter the same settings over and over again. That's not how it's supposed to be, is it?
The settings I'm talking about is DC precision, the zigzag scanning and so on. From what I've read I'm only supposed to do that for the first cell and then DVD-RB will use the same settings for every following cell?
Confused...
I was hoping I could just press "Encode" and then go to bed and wake up to a fresh new KDVD .

PS I asked this question earlier in this thread but never got an answer...

Please ignore my previous post...
I reinstalled CCE and ECL and now everything works!
Go figure...
