Questions

Is it really online — nothing to install?
Yes. The editor runs in the browser and the rendering happens on our GPUs. Your upload stays private to your account, and deleting the edit deletes the files.
How long does a render take?
Roughly the length of the clip — a one-minute video renders in about a minute or two, and you can keep editing while it runs.
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.
