 #### Frame Interpolation
 
-We use AMT as our frame interpolation model.(Thanks [AMT](https://github.com/MCG-NKU/AMT)) After sampling, you can use frame interpolation model to interpolate your video smoothly.

 1. Download the pretrained weights from [AMT](https://github.com/MCG-NKU/AMT), we recommend using the largest model AMT-G to achieve the best performance. 
 2. Run the script of frame interpolation.
