Subtitle Edit
An open-source subtitle editor supporting many subtitle and video formats, waveform and spectrogram timing, shot changes, spelling, conversion, OCR, speech recognition, and translation assistance.
Why use it
Subtitle Edit lets narrative and localization teams correct timecodes, reading speed, line breaks, and speaker cues against audio and picture, then export formats needed by cutscenes or trailers.
Where it fits
Use art, animation, audio, levels, and narrative to make the game easy to read and its world convincing.
What to check
The stable application is primarily Windows-focused while newer cross-platform builds remain in testing; OCR, transcription, and machine translation require human review, and cloud models add privacy and cost concerns.
