Converting MPL2 to SRT (SubRip)
MPL2 is a subtitle format most associated with SubEdit, a subtitling tool historically popular for Polish-language subtitles — a lot of MPL2 files in the wild are Polish releases, though the format itself has nothing language-specific about it. Its syntax is compact: [0][20]Hello there|How are you, where the two bracketed numbers are the start and end time in tenths of a second (so [20] means 2.0 seconds) and a pipe | marks a line break within the cue.
Converting to SRT multiplies those tenths back into real seconds and reformats every timestamp as SRT expects, converts the pipe line-breaks to actual new lines, and strips MPL2's single-letter style markers (like a leading /i for italics) since SRT has no equivalent syntax for them.
Questions about this converter
Why do MPL2 timestamps look so small compared to SRT?
[125], not a full timestamp string. This tool converts that back to normal SRT timing automatically.Does MPL2 support more than one line per cue?
| character between lines — this converter turns each pipe into a real line break in the output SRT.What's the file extension for MPL2?
.mpl2, though it's sometimes saved as a plain .txt file since the format itself is just text — this tool accepts either.Will italic markers like /i show up as text in my SRT?
Is there an API for this?
