Cannot reproduce results using the same demo

[DDDaxing]

Hi authors,

I have used the v2 ckpts to try to reproduce your results but I cannot keep the fidelity as yours. The whole face changed a lot.
Can you please share your parameters and have any idea why this happen?

my params:
python enhance_a_video.py \ --version v2 \ --up_scale 1 --target_fps 30 --noise_aug 250 \ --solver_mode 'fast' --steps 15 \ --input_path 'prompts/Einstein plays guitar.mp4' \ --save_dir 'results/' \ --filename_as_prompt

your results:

my results:

upscale=4 (will be adjusted below 2k), noise_aug=200
