Problems to Change DVD Color Subtitles

[johner23]

I bought 2 original dvd's and wanna make some security back up of them.

But in that back up I wanna change subtitle colors about one of that dvd's.

eg: DVD # 1 has yellow subtitles and DVD # 2 has white subtitles. I want to change the color subtitle from DVD # 2 to became the same as yellow one like DVD # 1.

How can I do that?

I try use PGCEdit, importing the colors from DVD # 1 to DVD # 2, in my HD. But the colors didn't change how I expect: the colors are different, despite I import exactly the same parameters from DVD #1 to DVD 2?

I really wanna know how to import / export such kind of subtitle colors between different dvd's, because in some authoring projects I really appreciate the original studio dvd color palletes ( concerning about subtitles ) and I want to reproduce them identical in my personal back ups and projects later.

Any clue and help about the subject are welcome.

Best regards.

The subpic colors are defined in two different places.

1) A color lookup table (CLUT) is defined in the PGC. This is where the 16 available colors are defined. You can edit or copy/paste them with PgcEdit.

2) The color index (ie, the number of the coloured square of the PGC, starting at 0) that must be used for each of the 4 colors of the subpic are defined in the VOB files. You cannot change the indexes with PgcEdit, but you can do that with the excellent DVDSubEdit.

The problem in your case is probably that the indexes stored in the VOBs of DVD 2 are not the same that the ones in DVD 1. Therefore, even if the colors are identical in the PGCs, the choice of which colors to use is different, and, of course, if you change only the CLUT, the result is not good.
You have to copy/paste the CLUTs (with PgcEdit) and change the color indexes in the VOBs (with DVDSubEdit).
For you, it is probably simpler to locate the yellow box in PgcEdit, and manually change its color to white.


Notes:
- If you use DVDSubEdit, you will have to apply the modification to all subpics (Use Edit -> Apply last modifications to all.) By default, only the current subpic is modified.
- It is also possible to change the transparency of the subpic colors with DVDSubEdit.

I do that and could locate the yellow one to replace the white one in one of the 16 colors available. But changing it wasn't enough. Even if I change it, the results are not what I expected. ;(

How I do this exactly ? After using PGCEdit, before with it...?

My main goal is to clone 100% one subtitle dvd color to the other one. And they're completely different dvd's. It's possible to do, right?

EDITED:

There is another way and I have just tested it. I too had the problem that there was no original IFO since my files had been converted from an AVI. BUT.... there is a way to manually specify the four colors in IFO-Edit.

You can manually enter the color info by entering the HEX-values in your IFO file. ----->
Open the ifo which contains the PGC with the subs. (VTS_PGCITI/VTS_PGC_? )
Select the PGC. Scroll down in the lower window until you see: "Color 0 Y Cr CB"
Doubleclick that and in the screen that pops up make sure only HEX is selected. Than enter the HEX-Values of the colours.
Save, confirm... Done !

I hope this will help you and everyone else in the future.

I'll try these manuals/ advices and see if I can clone one subtitle color dvd to the other dvd. Any found problems I'll tell you, ok?

Thanks for your patience. :)

Best regards.

The IfoEdit (archaic) method is exactly the same than the PgcEdit one, except that you have to enter the color values in decimal. You cannot choose the color interactively, in a dialog.

Using PgcEdit (or IfoEdit) before or after DVDSubEdit doesn't matter, but it is probably easier to change the CLUT first, since you will see the right colors in DVDSubEdit.


[EDIT:] I forgot that DVDSubEdit can also modify the CLUT. Therefore, you have everything you need in one program. You don't need PgcEdit or IfoEdit.
Read the DVDSubEdit guide again. Everything you need to know is very well explained.
