`beta_end` in animatediff sdxl noise_scheduler is different from the original sdxl

[Vincent-luo]

In this repo beta_end is set to 0.020 for sdxl noise_scheduler:

but in original sdxl noise_scheduler setting, beta_end is set to 0.012, refer to this. So is this because animatediff sdxl training use a different scheduler setting? If so, are there any reasons for the change? In my opinion, keeping the setting same as the original sdxl would be just fine.
