FAQ
Subtitle translator FAQ
Direct answers about subtitle quality, style modes, supported formats, credits, privacy, and common subtitle workflows.
1
Why is AI subtitle localization better than generic free translation?
Generic free translation is useful for rough drafts, but it often sounds too literal and needs more manual fixing. AI subtitle localization is built to produce subtitles that feel more natural and are closer to real publishing use.

What is the difference between Auto, Natural, and Literal?
Auto is the default mode for most subtitle jobs. Natural makes the subtitle sound more native in the target language. Literal stays closer to the source text and is useful for review.

Do you keep subtitle timing and cue structure?
Yes. The system replaces subtitle text while preserving cue timing and sequence.
4
Can I translate one subtitle file into multiple languages at once?
Yes. Choose multiple target languages and get separate outputs in one run.

Can I translate YouTube subtitles?
Yes. Export subtitles from YouTube or your subtitle workflow as SRT or VTT, translate them here, then upload the translated subtitles back where needed.

How are credits calculated?
Credits are calculated with a simple rule: ceil(duration_minutes) × target_language_count.

When are credits deducted?
Credits are reserved when a translation job starts. If a job fails due to platform-side issues, credits are refunded automatically.
