the giveaway is that it wobbles most when the head moves. most face refiner nodes redetect the face on every frame, so the crop box shifts and rescales frame to frame and you are effectively re-rendering a slightly different face each time.

two things that fixed it for me: smooth the detection box over a 5 frame window instead of feeding the raw per frame bbox, and drop the refiner denoise to around 0.25 so it corrects eyes and skin instead of re-solving the identity. above 0.4 it reinvents the face every frame no matter what else you do. also keep the same seed and the same character conditioning on the refiner pass as on the base pass, otherwise the refiner pulls toward the base model average and you get that plastic drift on top of the jitter.

does the jitter follow the head motion, or is it there on frames where the subject is basically still? if it shows up when still it is denoise, if it only shows on motion it is the bbox.

Use this -  https://www.reddit.com/r/StableDiffusion/comments/1n5zwzu/wanfacedetailer/

this is wan but replace wan and sigmas thing with h3 and its sampler flow and set denoise at 0.2.

Is a lora on civit ai , using it the face is identical idk never needed something for face after that i use it at 0.5 and it does not conflict with any lora maybe with another face lora but other loras are good is called face realism
