DESCRIPTION = '''
## Rerender A Video
### This space provides the function of key frame translation. Full code for full video translation will be released upon the publication of the paper.
### To avoid overload, we set limitations to the **maximum frame number** (8) and the maximum frame resolution (512x768).
### The running time of a video of size 512x640 is about 1 minute per keyframe under T4 GPU.
### How to use:
1. **Run 1st Key Frame**: only translate the first frame, so you can adjust the prompts/models/parameters to find your ideal output appearance before run the whole video.
2. **Run Key Frames**: translate all the key frames based on the settings of the first frame
3. **Run All**: **Run 1st Key Frame** and **Run Key Frames**
4. **Run Propagation**: propogate the key frames to other frames for full video translation. This part will be released upon the publication of the paper.
### Tips:
1. This method cannot handle large or quick motions where the optical flow is hard to estimate. **Videos with stable motions are preferred**.
2. Pixel-aware fusion may not work for large or quick motions.
3. Try different color-aware AdaIN settings and even unuse it to avoid color jittering.
4. `revAnimated_v11` model for non-photorealstic style, `realisticVisionV20_v20` model for photorealstic style.
5. To use your own SD/LoRA model, you may clone the space and specify your model with [sd_model_cfg.py](https://huggingface.co/spaces/Anonymous-sub/Rerender/blob/main/sd_model_cfg.py).
6. This method is based on the original SD model. You may need to [convert](https://github.com/huggingface/diffusers/blob/main/scripts/convert_diffusers_to_original_stable_diffusion.py) Diffuser/Automatic1111 models to the original one.
**This code is for research purpose and non-commercial use only.**
[![Duplicate this Space](https://huggingface.co/datasets/huggingface/badges/raw/main/duplicate-this-space-sm-dark.svg)](https://huggingface.co/spaces/Anonymous-sub/Rerender?duplicate=true) for no queue on your own hardware.
