Editing subtitles without an editor
Most subtitle problems don’t need a full subtitle editor. Combining two languages, for instance, is a matter of pairing each line with the one shown at the same time in the other file and writing both into a single file. Doing that by hand takes hours; a tool does it in a moment and keeps the timing of the original.
Dual-language subtitles are especially useful for learning. Put the language you are learning on top and your own language underneath, so you can follow the story and still pick up words and expressions as they are spoken.
Everything runs in your browser. Your files are read on your device, never uploaded, and the merged file is saved straight back to your computer or phone.
Frequently asked questions
Why merge two subtitle files?
Showing two languages at once is a popular way to learn a language with films and series. You read the original line and its translation together, without pausing to switch tracks.
Do both files need the same timing?
They should come from the same release of the video. If one of them is late, shift it first so both line up, then merge them.
Will my player show both languages?
The merged file is a single normal subtitle file, with each translation on its own line, so any player that reads the original format can show it.
