Align camera audio and external recorders against the active sequence.

A desktop plugin for audio sync, caption conversion, translation, and cleanup without leaving the timeline.
We will email you once when the installer is ready.
Align camera audio and external recorders against the active sequence.
Connect graphic text and TXT or SRT files to Premiere caption tracks.
Prepare translation, repeated-line cleanup, and shaping in one panel.
Preserve source sequences and default labels while separating review results.
Public distribution is being prepared. These are the usage policies for planned features. Upgrading your plan does not unlock unreleased features.
Start account connection in the Premiere panel, sign in to the Vietls account you want to use in your browser, and approve the connection. It is complete when the same account appears in the panel. Signing in on the web alone does not connect the plugin.
Mask Motion uses 1 credit per application. Transcription, translation and voice generation use credits based on duration or character count. Paid plans do not make these operations unlimited.
YouTube imports are not unlimited. The Premiere panel accepts up to 1 GiB per file. Separate web download limits are 2 GiB and 1080p on Starter–Business, or 8 GiB and 4K/8K when available on Enterprise. Request rate limits also apply.
