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 color drift between Hailuo (MiniMax) clips

Continuing a shot in Hailuo (MiniMax) from a previous clip’s last frame brings the same accumulating color drift every frame-seeded generator shares.

Why it happens

Hailuo decodes the seed frame, renders in its own color space, and re-encodes for delivery. The output frame differs slightly from the frame you exported, so each chained clip starts from a shifted color point.

How to fix it with Color Correct

Generate the next Hailuo clip from the previous clip’s last frame.
Load the previous (reference) and new (source) clips into Color Correct.
Run Frame-Pair Color Matching from the new clip’s first frame to the reference’s last frame.
Mask any new content so it doesn’t skew the match.
