encoded ASS subtitle into video by Hybrid got a different effect with original

[Selur]

yeah, i don't know which renderer was used, i made ass file with Aegisub, maybe VSFilterMod?

That's why I wrote:

Would need a debug output of the job creation to know what method was used.

Opened the sample in MPC-HC and there the subtitle also has no shadow.
Vapoursynth Preview, properly shows the subtitles with shadow.
Avisynth Preview, properly shows the subtitles with shadow.
->Enabling Config->Internals->Avisynth->Always use Avisynth should help.

Ps.: I'll also send you a link in a ~15min minutes via PM which allows to fix this by enabling 'Filtering->Vapoursynth->Misc->Script->Always use Vapoursynth'.
