Have you checked if ass2bdnxml can do what you're looking for ?

Absolutely not, it creates XML+PNG from ass file, so, i misunderstood you needs.

In that case, did you try BDSup2Sub ?

Other than BDSup2Sub, I think a much overlooked feature of SE is its so-called "SUP-editor".

Go File --> Import --> Blu-ray (.sup) subtitle file for edit. Once you've opened a SUP, you can Save as --> BDN xml/png (*xml). All images and positions will go unchanged. It's also able to convert xml/png back to SUP.

I wouldn't know how to split subs used in the "upper" from "lower" parts.

AFAIK the position is stored in the xml file. I need that in the png, i.e. an exact image of how it would appear on the screen.

That's the easiest part, there are many graphic utilities that can batch resize the canvas of an image. The hard part seems to be to have that image.

Indeed the positioning coordinates are in the xml file. In the SUP-editor you can import a background video where each subtitle is displayed at its correct position. Maybe I'm missing something here...

Beside the xml, I just plain need a png with the same size of the video resolution and the subtitles in the correct position as they are displayed on the screen.

I don't know if you ever dealt with anime but having subtitles both in the upper part and in the lower part, overlapping times, makes post editing necessary with a lot of PITA.

No, I have not dealt with these kind of subtitles. It would indeed strike me as quite elaborate.
About "overlapping times", does PGS format natively support this actually? Or would it mean then one SUP image ends at the same time the next - other - image starts? I remember doing subs for sign language where the sentences were build up word for word.

PGS is “simply” a series of images, showing in time order. That image can have whatever it wants: colors, text in every part of the screen and mostly in anime it happens to have multiple text lines, luckily almost always just in two parts of the screen, upper and lower. Well, there can be also signs translations but luckily there are only a few.

I asked many time to nikse to allow a sort of dual pass ocr, I.e. the upper part of the screen and the lower part. He never had time or will to listen to me, well some millions of anime watchers would beg to have that feature. If you are interested I could send you a sup to play with.

The one thing i know about overlapping timing, is that it seems it's not possible in XML+PNG, as if you import such a thing in Scenarist, it throws an error. The trick, is to create a stream of pictures, creating a different pictures when there is a change in the display and also split the timing at each of these changes.

For a 2 overlapping lines for exemple, you'll create 3 pictures. First when there i only the first line, a second with with the two lines, and a third with only the second lines. Also, you had to split the original timing for each lines in a 3 sequence continous timing.

But, it's VERY difficult with this kind of subtitles to not have "buffer underrun" error in Scenarist when it creates the subtitles when there is too much lines, or just too much overlapping continuous sentences.
This is the specific case of Blu-Ray. Maybe the sup/pgs format allow overlapping, but Blu-Ray don't (or just Scenarist don't).

You can have two distincts <event> with partially overlapping InTC and OutTC as long as:
- Each <Event> has a single <Graphic> (maximum of two concurrent <Graphic>)
- The <Graphic> do not spatially overlap.
- The palette of both <Graphic> are identical, or they can be combined as a single <256 colours palette.

This method has pros and cons:
- Better buffer management.
- Easy usage of inline effects like fade, position, color.
- More efficient stream encoding
- Limited to two objects
- PGS encoder is easy to implement: the BDN XML describes the data stream well enough.
- Limited to two overlapping event at any time.
- Palette has to be managed carefully in PNG generation logic.
- Palette management is constrained and hard to implement. The easy way out is to always use 127+1 colors per event. But this may not be enough for colorful subtitles.

Since the conditions above are just too much for most renderer, especially events sharing the same palette, most software rightfully use non overlapping <event>.

- Each <event> can have one or two <graphic>, whose content is irrelevant.
- No need to worry about spatial overlapping across different <event>.
- Each <event> has its own palette (which need to be shared by the two <graphic>). No need to consider neighbout events in time to generate the palette, only the active <graphic>(s).
- Cannot easily make use of BDN inline effects, as there's no logical <graphic> continuity in the <Events> timeline.
- Cannot encode PGS easily, as the BDN gives no helpful indication on the datastream structure, contiguous events, and so on.
- Way too many <graphic> generated, with often suboptimal splits and sizes.

And that's the shitty part.
- There's no smart BDN generators. The output is already too specific to the PGS format, differs too much from common subtitling needs to demotivate companies to implement it properly. Maybe Lemony Pro gets a few things right, but is still not ideal.
- "Stupid" BDN generators like avs2bdnxml or ass2bdnxml leave all the complexity to the PGS encoder. Scenarist and co do their best, but they all have their own issues. The main problem with Scenarist BDNImport is to allocate one buffer slot for every unique bitmap shape. It should just pad everything to the same size to reuse memory allocation. If your BDN is not nicely made, Scenarist won't be happy.

In essence, PGS encoders expect the BDN XML generators to address the complexities. And BDN generators wants PGS encoders to handle them. It is like politics, all blaming each others and not doing anything

Anyway, just my brain dump on the matter raised by jpsdr.

Look at this PGS, at a certain point it becomes a pain.

If you can help me to find a faster strategy to ass conversion, I will be really grateful.

@Nikse
There's something wrong with the SUP editor in version 4.0.3 Try importing a SUP with background video, do some positioning edits and save as XML/PNG. Now import the result back.
All durations come out negative which values start very small and negatively increase towards the last subs. Can you have a look? Tried on both Windows 7 and 10.

[EDIT] FYI version 4.0.2 also has this behaviour. Version 4.0.1 works well.

for your continuous work on Subtitle Edit, Nikse. XML/PNG issue are ironed out.

How do I use Synchronization - Point sync via another subtitle? I want to use timestamps in subtitles 1 to replace corresponding ones in subtitles 2.

When your file is opened, import timecodes of another file, it will import only its timecodes even if it contains text.

Hi Nikse,

I'm on latest SE 4.0.5. In the "Fix common errors" window, the function "Remove dialog dashes in single lines" prompts to remove dash (& space) in the second line, when first line doesn't end with a period.
For example:

This line ends with no period
- Second line beginning with with dash & space.


==>> is prompted for change into

This line ends with no period
Second line with dash & space.


It seems like SE assesses this kind of lines as being one. Can you have a look, please?

Thank you

After updating I lost the auto text scrolling on the left while playing the video. Is there a way to get it back?

Maybe by choosing the proper template under the Layout button?
