What it does
Subtitle Edit converts and edits subtitles with batch and command-line routes. Its tools include error checks, timing changes, synchronization, OCR, and handling of embedded subtitle tracks.
In Subtitle Edit 5, add files or folders to Batch Convert, choose the target format, chain optional fixes/timing changes and select the output folder. Presets restore the chosen operations; settings control encoding, source-folder output and overwriting. Image subtitles can be OCR inputs, while embedded/container tracks can produce separate language-labelled files. The headless seconv route runs on Windows, Mac and Linux with .NET and provides the same core conversion operations. Its default output is beside the input, with numbered names when a file exists; --overwrite permits replacement. A timing offset shifts cues, whereas source/target frame rates and speed changes alter timing differently. Local OCR/translation engines and configured remote services have separate dependencies and service terms.
