Can I use the Rebuilder matrix editor to rebuild indiviual cells??

[jamos]

Ie for some cells that the selected matrix chosen in rebuilder doesnt do a good enough job on could i manually use the matrix editor to encode them again using a different matrix while still keeping the same compression ratio or does this screw up the final output size of the finished video?

It shouldn't change the output size unless you are using OPV (one pass).

Thanks JD,

That would be a real sweet feature if there was a replace button on matrix builder program which would replace the existing cell, I can manually copy and paste for now. I like 90% of the cells using this matrix but i think other matrixes would work better on some cells.

As I told you on RME's thread I had some reports of different final Bitrates and Sizes... I couldn't reproduce it, though... but the problem may be there... so please double check the sizes (maybe the problem only occurs using some specific Rebuilder config)... anyway... I started working on a fix for that but I haven't finished, yet (been busy with another app.).

By the way... what's your usual encoder (maybe I can use your help to check this problem).

CCE SP 2.7 and Procoder 2

using CCE SP 2.7 there does seem to be a size difference..
the top file is the output from RME and the bottom is the original using rebuilder pro latest version. As you can see RME is bigger..using 2 passes so not sure what the issue is.

of course using procoder 2 you cannot use matrixes but its so good you really do not need to :p

I don't think that difference is enough to be significant. Encoders will swing one way or the other with any change... it averages out over the course of an entire DVD. The difference shown is only about 2/10s of a percent.

Thanks JD It would be a cool feature to choose different matrixes for cells..or groups of them.

Right now what I am doing is preparing then copying the D2VAVS directory into another temporary directory. then encode with dvdrebuilder pro. then for the cells I am not happy with, I use the RME looking at the original temporary directory (ie non recoded avs files) to test different matrixs on them to find a better one. then take the finished .m2v from the preview dir. (ie RMEs output dir.) then rename the file to the same name as the one in the D2VAVS dir. and replace it. Seems to work fine but have only worked with a couple of cells.

One question do I need to copy the D2VAVS dir or are the avs files the same even after encoding (ie do they still point to the original dvd source directory)?

[jdobbs]

Not sure if I understand the question completely, but the AVS files are set during PREPARE and don't change. In fact they are no longer used after an M2V is created.

The question may be more toward Rocxas..

I assume RME uses the AVS files to encode (just like Rebuilder pro does), after I run the encode process. If I use RME after the encode process does it looks at the already encoded M2V files instead of the original files from the source directory?

If i use a different matrix with RME on the avs file to produce a different m2v file will it be from the original source OR looking at the already encoded m2v file in the working directory? ( I do not want to recompress a already compressed m2v file)

Note: after examining RME it does look like it uses the avs files to read the original source even after a encode has been run.

yes... RME doesn't care about Rebuilder's phases except the prepare :)
It will get the data from the Rebuilder's Work Folder but it doesn't detect the .m2v files.

thanks..Rocxas..works good I can choose different matrixes per cell. Also using DVD Remake pro I can split cells that have different content combined (ie dark and light scenes or action and slow scenes combined in one cell) and apply different matrixes to them indiviually.
