[HELP] after encoding ass into mp4, but there is no subtitle at all

[ssdde]

using your dev version tested, still the same problem, mp4 with chapters very lag, fps drops half.

[Selur]

no clue why this happens to you.
Have you tried another source, to be sure it's not just this source that's somehow causing the issue?

[ssdde]

yeah, you can send me any sources with chapters to test, especially you said you have no problem with chapters there.

---

i using another source to encode, but this time it seems at the point of chapters got crash, can't encode complete. i creat output debug file for you.

That crashed at the start of the encoding (not when the chapters are added).
It's a bug in the Vapoursynth script.

I see the problem:

clip = subs = core.sub.ImageFile(clip=clip, file=".....sup", blend=False)

should be:

subs = core.sub.ImageFile(clip=clip, file=".....sup", blend=False)

-> will look into it

Send you a link to a dev version which should fix the .sup embedding problem in the dev version.

encode completed. using another footage still has same problem, the encoded MP4 with chapters got FPS-drop half, very lag.

[Selur]

What does 'mediainfo -f "PATH TO FILE"' say about the output that lags for you?

Cu Selur

[ssdde]

i using mediainfo to open, and select text mode, not find path you said.

you mean debug output? This option is not turned on.


i can't encode MP4 with chapters, only can encode MP4 without chapters, please help.

[Selur]

Assuming the path to the lagging .mp4 is "z:\Test.mp4" I wanted you to call 'mediainfo -f "z:\Test.mp4"'.
If you use the mediainfo gui text mode output is probably the same.

[ssdde]

where to run 'mediainfo -f "z:\Test.mp4", tell me please.

Mediainfo has no place to type to run that. mediainfo only supports select mode to view.
