IFOEDIT authoring: solution for fully working subtitles

[U977]

Hi all,

Just in case it would be interesting for others, I had a movie that I authored using IFOEDIT, with 2 audio streams and 2 subtitles streams.

I had problems with the subtitles: I could not display more than the first subtitles stream.

After some tests, and after the benefit of help from other forum members, here is the summary of what I needed to do to get fully working subtitles, including selection of the subtitle stream when playing with PowerDVD (selection of a stream through a right click on the video).

1- using IFOEDIT, copy subtitles colors from the original IFO
(assumption: only one PGC for the movie)
- Open the original IFO of the main movie in IFOEDIT
- click on VTS_PGCITI, and select the available PGC
- go to the "subtitle color" menu, and click on "copy colors from this PGC"
- Open the authored IFO
- click on VTS_PGCITI, and select the available PGC
- go to the "subtitle color" menu, and click on "paste colors into this PGC"

2- Check ratio values for every subtitle stream (my thanks to castellanos for pointing me to this)
- open the authored IFO (if you saved and closed at previous step)
- click on VTS_PGCITI, and select the available PGC
- for each subtitle stream, check the subtitle stream status. Values of this table are giving good results:
1 (-2147483648) for 1st stream
2 (-2147417856) for 2nd stream
3 (-2147352064) for 3rd stream
4 (-2147286272) ..
5 (-2147220480) ..
6 (-2147154688)
7 (-2147088896)
8 (-2147023104)
9 (-2146957312)
10 (-2146891520)

3- Check language type in VTSI_MAT
(I needed this to be able to select the subtitles in PowerDVD thanks to a right click on teh video. Otherwise, without that, the DVD will still play fine in standalone players)
- open the authored IFO (if you saved and closed at previous step)
- click on VTSI_MAT
- for each subtitle stream, the "language type" must be "present", and not "unspecified". To change it, double click on "sub-picture stream attributes"


This last step was based on a comparison of IFO files produced by DVDShrink (reauthor mode) and IFOEDIT. No problems to report so far with my DVDs.

Those values are not the same for all DVDs. They really depend on the stream ID (0x20, 0x21, ...) and for what type of display they are used (4:3, widescrean, pan&scan and letterbox). You must copy the values from the original IFO that correspond to your subtitles.

It is possible. Those values are more or less standard in PAL DVDs, I've made no experience with NTSC ones.
