FAQ

About Dubline

How accurate is the transcription?

Accuracy depends on audio quality — clean, single-speaker audio performs best. Technical jargon or heavy cross-talk may need light manual review.

Is the dubbed voice mine?

No. To avoid the consent and legal exposure that comes with voice cloning, dubbing uses a curated set of professional preset voices rather than cloning any voice you upload.

What file formats are supported?

Most common video and audio formats on upload; subtitles export as standard SRT / VTT, ready to drop into any editor.

What happens when I run out of free quota?

Free quota resets daily. For higher volume, or for AI dubbing, upgrade to Pro and pay by usage.
