Frequently asked questions

No for editing or export. A free username/password account is required for durable Turso saving, opening your projects on other devices, community publishing, and notifications.

Yes. There are no subscriptions, paid tiers, billing entitlements, watermarks, or export quotas.

Yes. In the Classic editor, open Export settings → Thumbnail for eight suggestions from your song's strongest moments, or use the Thumbnail maker with a video file, a picture or a project. Downloads come at the size each platform asks for (YouTube's 3840x2160, a 1280x720 phone upload under 2 MB, Shorts covers and more), and you can add your own text, logo and stickers.

Yes, if you want to: design one in the Thumbnail maker's Watermark tab (a corner logo, an @handle tag, a lower third, an end stamp and more), then switch it on for a project in Export settings and choose when it shows: the intro, throughout, the outro, or a mix. Sonic Weaver never adds a watermark of its own.

Only if you switch it on. "Made with Sonic Weaver" is off by default; when on, your PNG, JPG and MP4 downloads carry a standard metadata label (the software used, and that a person made it with non-AI tools) plus any credits you add. Nothing is drawn on the picture, and YouTube and most social sites remove the label when they process an upload.

The public catalog now has 60 canonical engines. Each engine owns at least six modes (370 in all) and shared 2D/3D geometry, effects, and audio controls. The original 2D visualizers are back, drawn by their own code, as the V2 visualizers; the 3D, 4D and ADV ones are not. Old template links still lead to the closest engine and mode.

The generation it comes from. V6, V5 and V4 are the current catalog, V6 the newest; V3 are the first looks of visualizers we have since rebuilt, kept exactly as they were; V2 are the 2D visualizers from June 2026 and V1 the very first ones, brought back so every look we have made stays available. Filter the templates wall's Engines view by version, or pick any of them in the editors, Generate visualizer and the Stream studio. A project made with one keeps it.

Classic is the guided creator. Studio exposes the full layer tree, node graph, timeline, inspector, geometry, assets, and character-rig workspace. Both edit the same composition without serialization loss.

Signed-in projects and revisions are saved in Turso. Music and files you import stay on your device: in Studio a project records each file's name and fingerprint, not the file, so on another device you import it again. Guests can explicitly export and import `.novusvis` project files but do not receive a durable browser library.

No. Analysis, rendering and export run in your browser, and saving a project never uploads your music or the other files you import. Studio keeps them in your browser's storage for this site and records a fingerprint, so on another device it asks you to import the same file again.

Use a passkey or a username plus one unused recovery code. Recovery codes are shown once, hashed, and single-use. Without a passkey, recovery code, or authenticated trusted session, the account cannot be self-recovered.

No. Projects and assets remain private until explicit publication. Publishing freezes one revision and uses a separate public preview derivative; later edits do not change the post.

Preview, still capture, and export share the deterministic composition graph, fixed-step runtime, and audio frame contract. Browser codec and color conversion can create small output differences.

All authoring views are available on phones. Capability-aware export limits constrained phones to 1080p, while supported desktops may export up to 4K.
