Convert between SRT, VTT, ASS, SBV, LRC and TXT with the timeline kept intact.
The input format is detected automatically and timestamps are rewritten for the target format; ASS effect tags and forced line breaks become readable text when you export to a plain format; lyrics files have no hour field, so anything past one hour is counted in minutes.
Anyone whose player refuses a subtitle file, and anyone moving material between an editor and a web player.
