## Subtitle Localization FAQ

### How does Smartcat’s subtitle localization workflow work?

Smartcat helps enterprise teams generate timed subtitles, translate them with AI, review language and timing in context, and export approved multilingual files from one connected workflow.

### When is AI subtitle translation enough on its own, and when should teams add review?

AI is a strong first pass for speed, but customer-facing, regulated, or high-visibility video usually needs review to confirm terminology, timing, brand voice, and regional nuance before release.

### Can reviewers edit subtitles in context before publishing?

Yes. Reviewers work with synced visual context so they can refine subtitle wording, timing, and readability while seeing how captions appear against the video itself.

### How do glossaries and translation memory improve subtitle quality over time?

Glossaries protect approved product names and regulated wording, while translation memory reuses validated subtitle phrasing across episodes, trainings, campaigns, and recurring video formats.

### How does Smartcat support multilingual QA for subtitle projects?

Teams can route subtitle work to internal stakeholders or external reviewers, compare outputs across markets, and apply final QA before files are delivered to downstream publishing systems.

### What export formats are supported for translated subtitles?

Smartcat supports common subtitle delivery workflows, including standard exports such as SRT and VTT, so approved files can move into the tools your teams already use.

### Can internal teams and outside reviewers collaborate in the same subtitle project?

Yes. Marketing, Learning and Development, regional teams, language leads, and external reviewers can work in one shared workspace instead of passing versions across disconnected tools.

### How does subtitle localization fit into broader enterprise localization operations?

Smartcat lets teams manage subtitles alongside websites, documents, knowledge bases, and other multilingual assets, so video becomes part of one scalable localization system.
