MicroDVD SUB to ASS Converter

Convert MicroDVD SUB subtitles to ASS with the timings preserved.

To convert MicroDVD SUB to ASS, paste the subtitle file above and the converted output appears immediately. Cue timings are preserved to the millisecond, and cues can be renumbered sequentially — which matters because several players silently stop at the first out-of-order index. ASS carries positioning, fonts and colours alongside the text. Converting to it produces valid but unstyled cues; converting away from it discards the styling entirely.

ASS carries positioning, fonts and colours alongside the text. Converting to it produces valid but unstyled cues; converting away from it discards the styling entirely.
