Batch style edit in ass subtiles

>>33655
Use a text editor that allows string replacing between all the open documents (for example, geany).

Alternatively, just iterate a string replace through bash.

I use this to batch-edit MKVs.

You'll need to do a bit of modification to edit the styles instead of the text, but it should be simple enough.

what type of subtitles are we talking about? considering you're talking about styles, i'm guessing ass/ssa? just open them in a text editor. one of the first blocks of text defines the various styles with a name, font, size, color, etc. if you want to change the style, just edit that one line that defines the style and it will apply to all lines of that style.

here's an example i pulled out of one of my subtitles created with Aegisub (this is the third block of text):
[V4+ Styles]
Format: Name, Fontname, Fontsize, PrimaryColour, SecondaryColour, OutlineColour, BackColour, Bold, Italic, Underline, StrikeOut, ScaleX, ScaleY, Spacing, Angle, BorderStyle, Outline, Shadow, Alignment, MarginL, MarginR, MarginV, Encoding
Style: Default,Arial,36,&H00FFFFFF,&H000000FF,&H00000000,&H00000000,0,0,0,0,100,100,0,0,1,2,2,2,10,10,10,1

so if you want to change Fontsize, you'd have to edit "36" to something else.

batch replace across multiple files also works in Notepad++ (which i would call the most widely spread text edtior for Windows which a lot of people actually like).
