  2. The result updates as you type. Adjust the available settings if needed.
  3. Review the result, then use Copy result or a download link when available.

Working with srt to ass

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.
