**Is your feature request related to a problem? Please describe.** Currently the AnimateDiff pipeline only supports SD 1.4 and SD 1.5. AnimateDiff with SDXL seems like a great addition as the quality is greater. **Describe the solution you'd like.** Currently the MotionAdapter cannot load the SDXL motion module : The following results in an error : ``` adapter = MotionAdapter.from_pretrained("vladmandic/animatediff-sdxl", torch_dtype=torch.float16) ``` ``` ValueError: Cannot load <class 'diffusers.models.unet_motion_model.MotionAdapter'> from vladmandic/animatediff-sdxl because the following keys are missing: up_blocks.1.motion_modules.0.norm.bias, down_blocks.2.motion_modules.0.proj_out.bias, up_blocks.1.motion_modules.1.transformer_blocks.0.ff.net.2.bias, down_blocks.3.motion_modules.1.transformer_blocks.0.ff.net.0.proj.weight, ... ``` **Describe alternatives you've considered.** An alternative solution would be to take inspirtaion from official implementation at https://github.com/guoyww/AnimateDiff or from https://github.com/s9roll7/animatediff-cli-prompt-travel/tree/main/src/animatediff **Additional context.** Official SDXL motion module : https://huggingface.co/guoyww/animatediff/blob/main/mm_sdxl_v10_beta.ckpt
