Practical solutions to solve the incoherent action of anime videos
Disjointed movements are a common problem in video generation, and Index-AniSora offers three targeted solutions:
- frame interpolation technique: Smooth animation by generating transition frames between keyframes. To do this, you need to prepare the start/end frame images, run the
frame_interpolation.pyScript and specify the keyframe directory - Time Mask Module: The built-in modeling architecture automatically completes the action sequence, so the user only needs to describe the action in detail in a text prompt (e.g., "swinging the sword from left to right").
- RLHF Optimization: Fine-tuning models using a reinforcement learning framework, running
rlhf_optimize.pyHigh-quality animation datasets with ratings are required.
It is recommended to start testing with frame interpolation, and then combine with text cue optimization and RLHF training if the result is not good. Huawei Rise NPU users can get better real-time rendering performance.
