Videolab

Videolab is an optional workspace for applying a configured restoration model to video. Enable it under Settings → Features, then configure its worker in the Videolab settings tab. The recommended setup imports the password-protected connection document produced by tessera-worker show-connection; advanced settings also accept the worker URL, token, and CA certificate separately.

Starting from a video

Right-click a video in Files and choose Open in Videolab. Select only a bounded interval for a preview, choose settings advertised by the connected worker, and start the preview job. A completed preview can be compared with the source and promoted to a full render.

Preview and full-render records are persistent. The history shows queued, running, completed, failed, and cancelled work. Completed or failed records can be cloned into a new draft without modifying the original settings record. Jobs continue to appear in the global jobs panel when you leave the workspace.

Privacy and recovery boundary

Tessera probes the local source, crops the requested interval, strips source metadata and non-video streams, segments the frames, and encrypts each bounded segment before transfer. Worker configuration, model identity, frame geometry, and other required technical fields cross the boundary; source filenames, paths, tags, and document metadata do not.

Cancellation is explicit and remains pending until remote cleanup and key destruction are acknowledged. Interrupted transfers resume only at persisted, authenticated chunk boundaries. A missing encryption key causes Tessera to cancel or clean up the old execution rather than assuming that encrypted work can still be resumed.

See the worker's own deployment guide for installation and network setup.
