video_name variable in Xvid4PSP using Avisynth script

[EgyptBeast]

Greetings,

I want to hardcode 20+ .ass subtitles into their videos. Neither Xvid4PSP 7 nor 6 can load .ass subtitles, so I have resorted to version 5. I am using assrender plugin (by TheFluff and lachs0r) to correctly display the subtitles. Here is what I want to exactly do using Xvid4PSP 5:

• Open the folder containing all of the videos (this loads all of the videos and put them on the task list)
  
  
  
• Edit the following script to be repeated on every video file
  
  
  
• Press Encode

Does such variable (video_name) exists ?
As for the video_path variable, this is the path where the script exists. I would like to know if there is a video_path variable in order to pass it to assrender plugin (assuming it's default working directory is different from the script's).


I am open to all solutions. I have tried many encoders (e.g. Handbrake, Avidemux, ...etc.) but all produces an output different from what is intented.
Regards.


EDIT: Also, since each video has a specific frame rate, is there a video_fps variable stored ?
Example:

DirectShowSource("video_name.mp4", fps=video_fps, convertfps=true)
