2024.01 - We recently release new v4.7-4.14 models. In our tests, 4.14 makes a great improvement for animation scenes. 🎉

This project is based on RIFE and SAFA. We aim to make them more practical for users by adding various features and designing new models. Because improving the PSNR index is not compatible with subjective effects, we hope this part of work and our academic research are independent of each other. To reduce development pressure, this project is for engineers and developers. For common users, we recommend the following softwares:

SVFI (中文) | RIFE-App | FlowFrames | Drop frame fixer and FPS converter

Thanks to SVFI team to support model testing on Animation.

Download a model from the model list and put *.py and flownet.pkl on train_log/

You can use our demo video or your video.

python3 inference_video.py --multi=2 --video=video.mp4 

(generate video_2X_xxfps.mp4)

python3 inference_video.py --multi=4 --video=video.mp4

(for 4X interpolation)

python3 inference_video.py --multi=2 --video=video.mp4 --scale=0.5

(If your video has high resolution, such as 4K, we recommend set --scale=0.5 (default 1.0))

python3 inference_video.py ---multi=4 --img=input/

(to read video from pngs, like input/0.png ... input/612.png, ensure that the png names are numbers)

The whole repo can be downloaded from v4.0, v4.12, v4.15. However, we currently do not have the time to organize it well, it is for reference only.

We are developing a practical model of SAFA. Welcome to check its demo (BiliBili) and provide advice.
