VobSub and editing font properties

[elmuz]

Hi all,
I was working on VobSub+Avisynth... (always for subtitling interviews jobs).
What I'm trying to do is writing a script (even complicated, it's a standard, once you did you always use the same) which can take .srt files and fuse them on a video, or creating a PNG/TIFF (with alpha) so that editors will be able to import them in Premiere and do the final editing.

So here what I have:
1) With VisaulSubSynch I prepare .srt/.ssa/... ...
2) By using Avisynth getting a blank alpha-video with subs, and import it in Premiere

Here's a skatch of the script:

DirectShowSource("C:\Documents and Settings\..\CLEAN VIDEO.avi")
TextSub("C:\Documents and Settings\..\SUBS.srt")

Then I tryed with a style file related to the srt file, as taught in VobSub guide, but with no luck... I tried alterate font, size and colours... (in bold what I changed)

Any suggestion for changing properties?

You're creating SSA (or ASS) files. So use an editor that supports that directly, like Aegisub, rather than trying to code them by hand.
