FAQ
Is video character replace free?
New users get free signup credits, enough for a few clips. After that, credits are billed per second — the create page shows the exact amount for your chosen resolution and length.
Which resolutions are supported?
Four tiers, billed per second: 480p at 20 credits/sec, 540p at 30 credits/sec, 720p at 50 credits/sec, 1080p at 100 credits/sec.
How long can a video be?
Three lengths: 5, 10, or 15 seconds, chosen at creation. Cost is length multiplied by the chosen resolution's per-second price.
What do the character photos and target video need?
Character photos: 1 to 5, JPG / PNG / WebP, up to 10MB each. Target video: 1, MP4 / WebM / MOV / M4V, up to 100MB. The clearer the character and the person in the video, the closer the replacement.
Is a prompt required?
No. The system default prompt is used unless you add your own — admins can edit the default in the admin panel, and you can add a custom prompt in Advanced settings on the create page.
How long does generation take?
It depends on queueing, video length, and resolution — longer videos and higher resolutions take more time. Track progress in your history.
