Strange video generated by Wan2.1 using sampling_steps=100

[Zctoylm0927]

Hi, I try to use the following script on single A800:
python teacache_generate.py --task t2v-14B --size 832*480 --ckpt_dir ./Wan2.1-T2V-14B --prompt "Two anthropomorphic cats in comfy boxing gear and bright gloves fight intensely on a spotlighted stage." --base_seed 42 --teacache_thresh 0.2 --sample_steps 100
After finish the pipeline, the generation speed is so fast like half a minute to take 99 steps which is significantly faster than expected. , and the video is so strange like everything is black.
I suspect there might be an issue with the different sampling steps. Could you please investigate this issue?

With larger sample_steps, you can try with lower teacache_thresh.
