How long does colorization take?

5 to 10 minutes for short clips, potentially longer for larger files. The AI processes each frame individually for accurate results.

How accurate are the colors?

DeOldify produces historically plausible colors based on scene context. Skin tones, sky, vegetation, and common objects are usually very accurate.

What is the render factor?

A quality slider from 7 to 40. Lower values (7-15) are faster with vivid colors. Higher values (21-40) are slower with more subtle, accurate coloring.

Does it work with any black and white video?

Yes — historical footage, old home movies, surveillance clips, and any grayscale video. Quality depends on the source footage resolution.

What video formats are supported?

MP4, WebM, and other common video formats. Output is always MP4 for maximum compatibility.

Can I colorize already colored video?

The tool is designed for B&W footage. Running it on colored video may produce unexpected or washed-out results.

Why is it more expensive than other tools?

Video colorization is computationally intensive — each frame is analyzed and colored individually. The 2-credit cost reflects this processing.

How much does it cost?

Each colorization costs 2 credits. New accounts receive free credits. If processing fails, credits are automatically refunded.
