Frequently Asked Questions

How does the AI video colorizer choose colors?

The model recognizes what is in the footage — skin, sky, foliage, clothing, buildings — and assigns natural colors that stay consistent from frame to frame. You can also describe the colors you want in the optional prompt.

Can I control the colors?

Yes. Name each thing and its color in the prompt, for example "green grass, blue sky, a red jacket". Leave the prompt empty and the colors are inferred from the footage automatically.

Does it work on faded or sepia footage?

Yes. Black-and-white, sepia and heavily desaturated footage all work. The output keeps the original framing, motion and detail; only the color changes.

Will the colors flicker between frames?

The model colorizes whole sequences at once rather than frame by frame, so colors stay stable across the clip and across cuts.

How long can the video be?

Up to 2 minutes is processed; longer input is truncated. The output keeps the input aspect ratio and is never larger than the input.

How much does it cost?

Pricing is per 5 seconds of video and depends on the output resolution: 480p, 720p or 1080p. The exact cost is shown before you generate, and new accounts get free credits.
