AviSynth rendered subtitles to BluRay SUP/PGS and BDN XML (v2.08)

[Oleg Rode]

Perfect! Perfect results! Yes, VSFilter rendering engine is ideal! Thank a lot! Yes, your program requires to write AviSinth script, to calculate frames, but it is produces perfect subs!

This is fantastic! It looks like my problem to render ASS subs to Blu-Ray SUP is closed.

Sorry for my English

A quick note:

The application crashes if avisynth parsed width is < ~700px or height is < ~104px.

There is a problem - flickering animated subtitles. What to do? i tried both BDSupEdit & BDSup2Sub - problem remains.

Here is an AviSynth script

MaskSub("Senjou no Valkyria - 01.ass",1280,720,23.976,33002)

And here is a program script

avs2bdnxml Script.avs Undefined und 720p 23.976 output.xml

And here is a subtitle file and AVCHD structure sample (burn it to DVD-RW disk, insert to Blu-Ray player and manually enable first subtitle)

Tested on my PlayStation 3. Sorry for my English

Thanks for reporting, I'll look into it when I have time.

Having the XML output would've been useful too, but I can generate this myself, of course. Also, maybe this is related to the problem sneaker_ger reported. If timing is 1 frame off after conversion to SUP, it could lead to flickering subs where exact timing is required.

[sneaker_ger]

I don't get any blinking when using MPC-HC or SupTitle (looks like this). Question is: does the blu-ray standard allow for such fast changing subtitles making it a PS3 specific problem?

[deank]

I get the same flickering in TMT and PS3...

Btw I decided to create a small front-end (gui like) to avs2bdnxml+bdsup2sup.

Tried to set 23.976 to avs2bdnxml - flickering exist.
Tried to set 23.976d to avs2bdnxml - flickering exist.
Tried to set 24 to avs2bdnxml - flickering exist.
Tried to set 24 to avs2bdnxml and manually set 23.976 in .xml file - flickering exist.
Tried to set 24 to avs2bdnxml, set 24 in AVS script and set 24 fps in tsMuxeR for video - flickering exist.
Tried to set 25 to avs2bdnxml, set 25 in AVS script and set 25 fps in tsMuxeR for video - no sync but also no flickering.

Guys, I don't know what to do. Where to dig? Is there a problem with accuracy? Something like 23.976 is NOT the same as 24000/1001?

Should be fixed now.

I have now generated a couple of different XML files, like you said. There are still some bad timecodes in the output, for example:

<Event Forced="False" InTC="00:00:53:16" OutTC="00:00:53:16">
<Graphic Width="1280" Height="720" X="0" Y="0">00001288.png</Graphic>
</Event>
<Event Forced="False" InTC="00:00:53:16" OutTC="00:00:53:18">
<Graphic Width="1280" Height="720" X="0" Y="0">00001289.png</Graphic>
</Event>

As you can see, both start at the same timecode. Probably some rounding errors. I'll try to fix this. It might help with the flickering too.

[Oleg Rode]

Tried manually remove these bad timecodes from xml file

<Event Forced="False" InTC="00:00:53:16" OutTC="00:00:53:16">
<Graphic Width="1280" Height="720" X="0" Y="0">00001288.png</Graphic>
</Event>

Bad luck - flickerings exist

[sneaker_ger]

Could you do a test with PunkGraphicStream? Maybe it's not a problem of the subtitles but of the muxer (or the player). Do you have the possibility to mux with a different program (e.g. Scenarist)?

[ps auxw]

I have corrected timecode calculation now. (Drop timecode support is dropped for now, the results weren't correct anyway. If anybody needs it and can verify calculated timecodes, I can try adding it back correctly.) Even if removing the duplicate timecode entries failed to fix the flickering, maybe it still helps somehow? Otherwise, try what sneaker_ger suggested.

Not working - flickering exist.

Results much worse. Flickerings are on all animated subs.

OK, i'll try.

[sneaker_ger]

The new version 1.9 still creates overlapping timecodes on Oleg's sample:

<Event Forced="False" InTC="00:00:03:17" OutTC="00:00:03:18">
<Graphic Width="1280" Height="720" X="0" Y="0">00000089.png</Graphic>
</Event>
<Event Forced="False" InTC="00:00:03:18" OutTC="00:00:03:19">
<Graphic Width="1280" Height="720" X="0" Y="0">00000090.png</Graphic>
</Event>

Or am I misinterpreting the timecodes?
Is "00:00:03:17" the first frame it is to be shown on and "00:00:03:18" the first frame it is supposed to be NOT shown on?

[sneaker_ger]

@ Oleg:

Could you test this sample (rename to "valkyria.7z", it somehow screwed up the name) on your PS3? Don't mind subtitles and video not being in sync, only look for blinking.

I think this is the case, but I am not sure. It would be nice if anybody knew for sure and clarify the situation.

[sneaker_ger]

I had a little talk about the timecodes being 1 frame off in BDSup2Sub and it turns out that it's not an error in BDSup2Sub (nor in BDSubEdit) but actually an error in SupTitle. It just so happens that there's also an error in PunkGraphicStream and both errors nullified each other which made me draw a wrong conclusion.

There is a problem - wrong AVCHD structure. I created a new one and put .m2ts file from your image. Result is not good, but I noticed a strange thing - sometimes subs are playing correctly. In other words - I start to play sample, somewhere in the middle I press "previous chapter" button and sample plays again from the beginning (of course we got only one chapter). I do this again and again and sometimes (somewhere in 1 of 7 times) there is no flickering. At least at "fading in" period. May be subs are changing too fast? May be to try slow down animation? I.e. let's 1 picture will be visible during 2-3 frames.

Sorry for my English

[sneaker_ger]

That could be possible, but it would be a shame having to cripple animations. It also does not explain why there are no problems when using 25 fps.
What about this one:

Much worse than previous Flickerings are all the time.

[sneaker_ger]

Ah, my fault. Try this one.
