View Full Version : Permanent subtitles bug? - I just get black bitmaps with LOTR

Region 4 PAL

Subtitles are:
1. English (hearing impaired)
2. Greek
3. English Titles (elves translation, etc, only 20 bmps - first at 7 mins in).

It's only the 3rd stream that's a problem. I try to select it when the subtitles box comes up and get access violation, but it is selected.

Subtitles are extracted seemingly normally, but the bitmaps are all black when you look at them, but they do differ in size (but do not match the dimensions they would be if extracted properly).

Anyway, I used SubRip to extract the subtitles as bitmaps (and it took a while to get them looking how I like them, damn learning curve). I copied these over the DVD2SVCD bitmaps (with correct filenames) and used crash recovery (I had cancelled DVD2SVCD after video encoding had started).

All is fine and dandy until the first subtitle should be inserted, then all that's encoded for the rest of the film is an access violation error.

I used subrip to get an srt file, then converted it so ssa. I opened the avs in virtualdub and am frameserving from there to CCE, with the subtitler filter enabled. I initially cancelled the encode after the first 8 mins and the first subtitle was displayed as it should be. So all should be well.

Anyway, is this just a one off case? Are there other ways around it?

Thanks :)

Hi-

I'm sorry I can't help you with the bitmap problem. But, newer versions of SubRip can rip directly to SSA. And by using the TextSub plugin for AviSynth you can avoid frameserving with VDub, and just insert the subs into the .avs during the editing stage. You'll gain back some speed as well.

The weird thing is that virtualdub finished okay..wasn't too slow...RT of a bit over 1.0...but the output file was only 2:34 instead of 2:51...and it wasn't as if a particular chapter was missing. e.g. chapter 2 started at 5 mins in instead of 7 mins in.

Anyway, I'm now using textsub with the SSA in avisynth, so thanks for the tip. Hopefully it'll turn out right this time.

It'd be nice to know to apply permanent subs though, I wouldn't ever want to have to do OCR on foreign lanuage film's subs.

Well it turns out that the access violation error was on account of the fact that the bitmaps from subrip were 4 bit, not the 24 bit used by DVD2SVCD. I converted one using paint (but I imagine there's a batch conversion program that'll do it) but the subs still look shocking because the dimensions are different.
