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

[Selur]

Send you a link to a dev version, in which it does work if 'Config->Containers->Mp4 Settings->FFmpeg instead of MP4Box' is enabled.
Going to bed now, will try to look at it some more during the week, but I don't know whether I'll find some time, since I have a really busy week ahead of me.

Cu Selur

Ps.: You could also test whether this only happens when preset 'ultrafast' is used, or also with 'superfast' (which uses b-frames).

I've tried other preset before, "faster", after encode still has the same problem.

I've tried other preset before, "faster", after encode still has the same problem.

keep the two options enabled:

'Config->Containers->Mp4 Settings->FFmpeg instead of MP4Box',
'Create qp file chapters',

and encode, the export MP4 file is good, no lag, no problem. But there are two menus in it, it's repeated. And why there are both 3 menus in Video and Audio?

And why there are both 3 menus in Video and Audio?

No clue, what MediaInfo wants to indicate with that.

Seems to be a bug in mp4box, see: https://github.com/gpac/gpac/issues/1853
-> once this is fixed, I'll create a dev build and send you a link
