This project is the implement of RIFE: Real-Time Intermediate Flow Estimation for Video Frame Interpolation. Currently, our model can run 30+FPS for 2X 720p interpolation on a 2080Ti GPU. It supports arbitrary-timestep interpolation between a pair of images.

Video Frame Interpolation
You can use our demo video or your own video.
python3 inference_video.py --exp=1 --video=video.mp4
(generate video_2X_xxfps.mp4)
python3 inference_video.py --exp=2 --video=video.mp4
(for 4X interpolation)
python3 inference_video.py --exp=1 --video=video.mp4 --scale=0.5
(If your video has very high resolution such as 4K, we recommend set --scale=0.5 (default 1.0). If you generate disordered pattern on your videos, try set --scale=2.0. This parameter control the process resolution for optical flow model.)
python3 inference_video.py --exp=2 --img=input/
(to read video from pngs, like input/0.png ... input/612.png, ensure that the png names are numbers)
python3 inference_video.py --exp=2 --video=video.mp4 --fps=60
(add slomo effect, the audio will be removed)
python3 inference_video.py --video=video.mp4 --montage --png
(if you want to montage the origin video and save the png format output)
Image Interpolation
python3 inference_img.py --img img0.png img1.png --exp=4
(2^4=16X interpolation results) After that, you can use pngs to generate mp4:
ffmpeg -r 10 -f image2 -i output/img%d.png -s 448x256 -c:v libx264 -pix_fmt yuv420p output/slomo.mp4 -q:v 0 -q:a 0
You can also use pngs to generate gif:
ffmpeg -r 10 -f image2 -i output/img%d.png -s 448x256 -vf "split[s0][s1];[s0]palettegen=stats_mode=single[p];[s1][p]paletteuse=new=1" output/slomo.gif
Place the pre-trained models in train_log/\*.pkl (as above)
Building the container:
docker build -t rife -f docker/Dockerfile .
Running the container:
docker run --rm -it -v $PWD:/host rife:latest inference_video --exp=1 --video=untitled.mp4 --output=untitled_rife.mp4
docker run --rm -it -v $PWD:/host rife:latest inference_img --img img0.png img1.png --exp=4
Using gpu acceleration (requires proper gpu drivers for docker):
docker run --rm -it --gpus all -v /dev/dri:/dev/dri -v $PWD:/host rife:latest inference_video --exp=1 --video=untitled.mp4 --output=untitled_rife.mp4

We use 16 CPUs, 4 GPUs and 20G memory for training:
python3 -m torch.distributed.launch --nproc_per_node=4 train.py --world_size=4
First of all, we are sorry for the troubles caused by multiple submission versions to the follower. We will not modify the weight and method of the model baseline anymore. We also tried our best to check the test results of all other methods. You are welcome to cite our results.
Major Revisions：
2021.3.18 arXiv: Modify the main experimental data, especially the runtime related issues.
2021.8.12 arXiv: Remove pretrained model dependency and propose privileged distillation scheme for frame interpolation. Remove census loss supervision.
2021.11.17 arXiv: Support arbitrary-time frame interpolation, aka RIFEm and add more experiments.
