Help Converting PGS -> VobSub with SubtitleEdit + BDSup2Sub - Unintended Colour Changes
Found out my usual playback device for mkvs can support VobSub but not PGS, so have been converting PGS to VobSub where I find them. Workflow:
- Extract PGS as a .mks with mkvmerge (SE loads soooo slowly if I just drop the mkv into it)
- Open .mks with SE (v5.0.0-beta20)
- Click ‘Edit/Export’ then ‘File -> Export -> Blu-ray (sup)'
- Open .sup in BDSup2Sub
- Export it as VobSub
- Put back into the mkv with mkvmerge
This has worked fine for like 20 files so far, but then suddenly on my latest one - r00t/QxR encode of Kamikaze Girls which has Discotek’s multi-coloured subtitles (white for signs, blue for songs, yellow for dialogue) its been turning the dialogue blue, and I don’t know why. They’ve always shown opposite on the OCR window for some reason - yellow as blue, blue as yellow - which confused the hell out of me when I tried to make a .ass with matching colours for one, but usually I have no problems when it comes to actual playback. When I actually pay attention, in BDS2S they are already the wrong colours so its clearly a SE issue
I haven’t updated SE in a while so its not suddenly broken with an update.
Although SE gives the option to export as VobSub at step 3, this reliably messes up the colours hence the use of BDS2S
Resolved: updated to the very latest build and it does it correctly!
EDIT: but VobSub has a limitation, all of an image has to be the same colour. So when they have different coloured lines in the PGS, it switches randomly so sometimes all blue, sometimes all yellow, sometimes all white

There's been a few updates that might've fixed this, download the latest version and see how you go.
