View Full Version : Question about DVD palette exchange formats

Hi,

As some of you may know, there is no palette support in the SUP format. This is because this format comes from the DVD world. When you extract a SUP file, an IFO file that holds the corresponding palette is also extracted.

However, using SubtitleCreator or other applications, it is now possible to generate your own SUP files. These files can then be used to add subtitle streams to existing or new DVDs (using muxman for example).

With Paddington, we have noticed that many users have color problems. So we have decided that we will add some way for the user to export the palette that was used to generate a SUP file with SubtitleCreator. Following some suggestions (and some other software's choices), we have decided that we will create a dummy IFO file where only the palette will be significant. The other info will be invalid.

Here comes my two questions, (number 2 is especially to fansubbers and karaoke makers):

1°) Should we name this file out1.sup.ifo or out1.sup.palette.ifo (if the sup file name is out1.sup) or something else?

2°) What other format(s) should we support for the palette export? Please share your knowledge about this subject.
(I can only think about .mxp format (muxman project file). I must only check that muxman can accept such a file holding palette info only.)

Cheers

Hi Manusse,

If you can supporting PgcEdit raw color table format (.clb), I'm sure that would helpful to some people. Although PgcEdit apparently does import .MXP and .IFO.

Hi kumi,

I will also implement the .clb conversion as you request. For my tests, however, I need to be able to import/export clb files with pgcedit.

However I don't know how to use pgcedit. Could you please tell me how to import/export clb files with pgcedit.

Thanks in advance
Cheers

Sure thing:

1) Load DVD in PgcEdit.
2) Select a PGC, and press Return (or right-click and select Edit PGC.)
3) In the "Sub-picture Color Lookup Table" box, Click Export or Import.
4) If exporting, answer "Yes" to the dialog that asks "Export YCrCb colors as 64 bytes raw data?"

Thanx for that. Working fine.

Ok, I've implemented the palette import/export.

Next version of SubtitleCreator will be able to import/export palettes files using IFO, clb (PgcEdit) and mxp (muxman) formats.

Also it will be possible to copy/paste the palette between PgcEdit and SubtitleCreator.

Hope you'll like it.
