Useful next steps
Working with merge subtitles
A subtitle file combines text with time ranges. Converting SRT to VTT changes its representation; shifting subtitles changes timing; translation changes the language. Generating subtitles from speech adds a transcription step before the captions can be reviewed.
Common questions
Does converting subtitle formats fix synchronization?
No. A format conversion generally retains the source timing. Constant offsets can be adjusted with a shift; drift across a recording may require timing alignment or manual correction.
Why do translated subtitles need another review?
Translated text may be longer than the original even when its meaning is correct. Review line breaks and reading speed without assuming that the original cue duration suits every language.
