What it does
Jubler creates, edits and converts subtitles, with a waveform, VLC preview, translation mode and configurable validation.
Two-point synchronisation helps align a file whose timing has drifted, while validation checks support a consistent delivery standard. Its dependencies are concrete: VLC supplies preview and ASpell supports spell checking. Set up those components before expecting every editing feature to work.
Strengths
- Waveform timing and validation support detailed subtitle preparation.
Watch out for
- Preview and spell checking depend on external applications.
