MicroDVD to SRT

Convert MicroDVD .sub files to SRT

MicroDVD counts frames, not time. Captionry reads the frame rate from the file's header line, or uses the one you pick, and writes standard SRT timestamps.

How to

How to convert SUB to SRT

  1. Drop your .sub files

    Drop files or a whole folder onto the converter. Each file is checked and listed with its encoding and cue count.

  2. Keep SRT selected

    SRT is preselected on this page. Set a time offset or strip tags under Options if you need to.

  3. Download

    One file downloads as .srt; several come as one zip with your folder structure kept.

Details

What changes in the conversion

  • A header line such as {1}{1}23.976 sets the frame rate. Without one, the rate under Options is used (23.976 to 60 fps) and the file shows a note.
  • The | character becomes a line break; {y:i} and {Y:i} become italics. Other {c:...} and {f:...} codes are removed.
  • A cue with an empty end frame ends when the next one starts, or after 3 seconds.
  • Only text MicroDVD files convert. Image-based VobSub .sub files (with an .idx next to them) are reported as not convertible.

FAQ

Questions

The timing drifts further as the file goes on. Why?

The frame rate is wrong. Open Options, choose the frame rate of the video the file was made for (often 23.976 or 25) and convert again.

How do I know if my .sub is MicroDVD or VobSub?

MicroDVD is a text file whose lines start with {frame}{frame}. VobSub .sub is a binary image file that comes with an .idx file; Captionry lists it as not convertible instead of guessing.
