Using Motion LoRAs with PEFT You can also leverage the PEFT backend to combine Motion LoRA’s and create more complex animations. First install PEFT with Copied pip install peft Then you can use the following code to combine Motion LoRAs. Copied import torch |

export_to_gif(frames, "animation.gif") FreeInit is not really free - the improved quality comes at the cost of extra computation. It requires sampling a few extra times depending on the num_iters parameter that is set when enabling it. Setting the use_fast_sampling parameter to True can improve the overall performance ... |
