Overview

Practical-RIFE

This project is based on RIFE and aims to make RIFE more practical for users by adding various features and design 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 difficulty, this project is for engineers and developers. For users, we recommend the following softwares: Squirrel-RIFE(中文软件) | Waifu2x-Extension-GUI | Flowframes | RIFE-ncnn-vulkan | RIFE-App(Paid) | Autodesk Flame | SVP |

For business cooperation, please contact my email.

Update log

Installation

git clone [email protected]:hzwer/Practical-RIFE.git
cd Practical-RIFE
pip3 install -r requirements.txt

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

Run

Video Frame Interpolation

You can use our demo video or your 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 high resolution, such as 4K, we recommend set --scale=0.5 (default 1.0))

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)

The warning info, 'Warning: Your video has *** static frames, it may change the duration of the generated video.' means that your video has changed the frame rate by adding static frames. It is common if you have processed 25FPS video to 30FPS.

Report Bad Cases

Please share your original video clip with us via Github issue and Google Drive. We may add it to our test set so that it is likely to be improved in later versions. It will be beneficial to attach a screenshot of the model's effect on the issue.

Model training

Since we are in the research stage of engineering tricks, and our work and paper have not been authorized for patents nor published, we are sorry that we cannot provide users with training scripts. If you are interested in academic exploration, please refer to our academic research project RIFE.

To-do List

Multi-frame input of the model

Frame interpolation at any time location

Eliminate artifacts as much as possible

Make the model applicable under any resolution input

Provide models with lower calculation consumption
