I'm making dance videos in Kling from a single character image and the face drifts or morphs partway through almost every generation. Body motion looks fine, but by a few seconds in it's not the same person.

What I'm doing: [Image-to-Video / Motion Control],

Kling version 3.0, 10sclips,

standard mode.

Any help please?

10s in standard mode is where it drifts, thats the main issue. go pro mode and cut to 5s clips, then chain them using the last frame as the start image of the next one. also the face has to be big enough in the reference, if the character is full body the model has almost no pixels of the face to keep. i generate a close up first and use that as reference, then the dance clip.

Try lowering the motion strength and using a clean, high-quality reference image. Also test 5 6s clips instead of 10s, as longer generations can cause more face drift. Keeping head movement moderate may help preserve identity.
 
add to the prompt, "from the shoulders down, dont show her face" haha! No serioiusly, try different models until one works best for what you do.
 
Thanks for the insight, I will get back to trying these suggestions
 
In Kling 3.0 you can stop the face drift by turning on the Face Lock toggle in the Motion Control panel and setting Consistency Strength to 0.9.
I used that combo on a 10s clip on my i7-13700K and the face stayed the same for the whole video.
 
Try turning on Face Lock in the Advanced tab of Kling and set the Consistency Window to four seconds; this keeps the same face but can make the dance look a bit less smooth. Split your ten second clip into two five second parts to avoid drift.

not a bad process, make sure the reference image has the models 360 view. like front back side views, you can easily generate something like that with nano banana and use that as a main go to reference image. you can always change the clothes and outfits later.
 
Try enabling the Identity Preserve flag in Kling's advanced settings, and use a fixed seed for the whole clip.
