Good day to everyone.
I didn't find another topics about my request because i think it isn't common.
I'm using Xvid4Psp 5 (last version for 5) to hardsub a mp4 video with ass subtitle. I want to add something better to replicate a blue fire on a logo.
My problem is simple: i have to add this sequence of PNG files.
I tried with a function which is inside in VsFiltermod.dll but i receive an error from the software: "Invalid arguments" on the function Textsubmod("sub.ass"). The files are in the same folder and I have already tried to put the absolute path.
I don't want that you help me with this dll, but if there is a function or command which I can use in the AVS editor of the Xvid4Psp to complete this task. Or inside ass file.

Inside of sub.ass I have the right timing and I have ~40 PNG files.
The MP4 file is 1280*720 X264 AAC.

Thank you!
