Why do AI video clips drift in color at all?

Every export, re-encode, and image round-trip nudges color. Generators decode a seed frame, render in their own color space, then re-encode to 8-bit yuv420p for delivery — and each conversion clips and rounds values slightly. Chain several clips and those small shifts accumulate into visible mismatches in brightness, contrast, and hue.

Does Color Correct re-grade the whole clip or just match it?

It matches. Color Correct computes a color transform from a reference frame (or frame pair) and applies it so the corrected clip lines up with your reference — it doesn't impose a creative grade. You stay in control of the look; Color Correct just removes the unwanted drift.

Fix Luma Dream Machine color shift

Luma Dream Machine’s extend feature continues a clip from its final frame, and the continuation tends to land a small step away from the original in color and exposure.

Why it happens

Each extension re-decodes and re-renders from the prior frame, then re-encodes to 8-bit. The handoff isn’t color-exact, so the extension begins from a shifted point — and repeated extensions stack the shifts.

How to fix it with Color Correct

Identify the original clip (reference) and the extension (source).
Load both into Color Correct.
Frame-pair match the extension’s first frame to the original’s last frame.
Let Color Correct interpolate the transform so the correction blends across the extension.
