Why use DocuAlign for subtitle translation?
Subtitle translation fails when timestamps are treated like text.
- Timestamps can be edited or reformatted accidentally
- Line breaks can drift away from the source subtitle
- Reviewers cannot quickly compare source and target lines
DocuAlign keeps timing and text aligned.
- Preserves subtitle timing and sequence numbers
- Translates dialogue while keeping source context visible
- Exports subtitle files ready for video workflows
DocuAlign vs. generic subtitle translation

- • Long subtitle files are hard to validate manually
- • No synced review for source and target captions
DocuAlign
- Built around subtitle file structure
- Keeps each caption aligned with its translation
- Designed for fast review before export
