I need a software to edit certain "subtitle style" in batch form. I can edit certain style in subtitle edit soft and change all the lines with that style but I don't know how to edit a "style" and change that style in 10 subtitles at the same time
What to do ?
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):
Format: Name, Fontname, Fontsize, PrimaryColour, SecondaryColour, OutlineColour, BackColour, Bold, Italic, Underline, StrikeOut, ScaleX, ScaleY, Spacing, Angle, BorderStyle, Outline, Shadow, Alignment, MarginL, MarginR, MarginV, Encoding
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).
