Why is the character's identity poorly maintained?

[zzk88862]

this is my execution command：
python enhance_a_video.py --version v2
--up_scale 2 --target_fps 24 --noise_aug 100
--solver_mode 'fast' --steps 15
--input_path prompts_v3
--prompt_path prompts_v3/text_prompts_v3.txt
--save_dir 'results/'

input video：

output video：

a.woman.in.black.is.walking.towards.camera.mp4

noise_aug=50; up_scale=4;
And crop the black borders.

thanks for your reply

Are you using the v2 model, and is the prompt 'A person strides forward'?
And Is cropping the black borders to make the video square?

tks

yes, v2 model with prompt "a woman in black is walking towards camera", and crop the black borders before venhancer.
