Frequently asked
What style does the output use?+
A single 'Default' style at 72px Arial, white fill, black outline, centered, bottom margin 80 — designed to look reasonable on a 1920×1080 timeline before you customize it.
Can I open the result in Aegisub?+
Yes — Aegisub reads the [Script Info], [V4+ Styles], and [Events] sections this converter emits.
Will it preserve italics or bold from the source SRT?+
No. SRT inline tags aren't ported to ASS override codes in this converter. Restyle in Aegisub after import.
