Questions

Will the text still be readable if someone pauses the video?
No — the blur is baked into the rendered file at the strength you choose. Crank the slider until the preview is unreadable; what you see is exactly what renders.
The camera moves a lot — does the blur keep up?
Yes, the tracker follows the tapped surface through pans and handheld shake. For hard cuts to a different angle, add one reference tap on the new angle.
How much does it cost?
One credit covers one minute of video, and you get 3 free credits at signup — no card needed. Packs start at $9 for 15 minutes.
What formats can I upload?
MP4, MOV, and WebM, up to 5 minutes per video. The result downloads as MP4 with the original audio kept.
What happens to my video afterwards?
Your uploads are private to your account. Deleting an edit from your history also deletes the rendered result — and the uploaded video itself once no other edit uses it.
What if the edit tracks the wrong thing?
Re-rendering the same video within 24 hours is free (up to 3 fix-it renders per edit), so correcting a track never costs extra credits.
