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.

Do I need to match every clip in a long Kling sequence?

Match each clip to the one before it (pairwise). Because drift accumulates, correcting each handoff keeps the whole sequence locked to your original reference instead of slowly wandering.

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 Kling clips

Extending a shot in Kling by feeding the previous clip’s last frame as the next start frame is the standard way to build longer sequences — but each handoff introduces a small color shift that compounds across cuts.

Why it happens

When you export a frame from one Kling clip and use it to seed the next, the frame is decoded, re-encoded, and run back through the model. Kling renders in its own internal color space and delivers 8-bit yuv420p, so the seed you feed in is never byte-identical to the frame you pulled out. The new clip starts from a slightly shifted color, and the next handoff shifts it again.

How to fix it with Color Correct

Generate your next Kling clip as usual using the previous clip’s last frame.
In Color Correct, load the previous (reference) clip and the new (source) clip.
Use Frame-Pair Color Matching to match the new clip’s first frame to the reference clip’s last frame.
Let Color Correct interpolate the color transform across the clip so the correction is seamless, not a hard cut.
Mask out any genuinely new content (a new character, a sky change) so it doesn’t skew the match.

Recommended settings

Export seed frames with Color-Recovery (level 2) so the frame you feed Kling already pre-compensates for encoding drift.
