# RIFE: Real-Time Intermediate Flow Estimation for Video Frame Interpolation
Creates sequence of interpolated frames between given input images
## Run
> python interpolate.py --input samples/ --output frames/ --buffer 25 --multi 25
interpolating 4 images
image samples/image000.jpg ssim 0.99 buffer 25 frames
image samples/image001.jpg ssim 0.54 create 69 frames
image samples/image002.jpg ssim 0.45 create 69 frames
image samples/image003.jpg ssim 0.55 create 69 frames
image samples/image003.jpg ssim 0.99 buffer 25 frames
frames 259 time 4.24
- Reads input images from `samples/` and writes output images to `frames/`
- Number of generated frames will be 70x input frames
- Start and end will be buffered/padded with 25 frames

- Creates a video file from interpolated frames
## Options
> ./interpolate.py --help
--model MODEL path to model
--input INPUT input directory containing images
--output OUTPUT output directory for interpolated images
--scale SCALE scale factor for interpolated images
--multi MULTI number of frames to interpolate between two input images
--buffer BUFFER number of frames to buffer on scene change
--change CHANGE scene change threshold (lower is more sensitive
--fp16 use float16 precision instead of float32
## Example
Both examples are created using [SD.Next](https://github.com/vladmandic/automatic)
### Using [AnimateDiff](https://github.com/yownas/seed_travel) extension
https://github.com/vladmandic/rife/assets/57876960/65cf5c7d-e376-4ca9-b03e-2c81d2d79b2f
[Video](./samples/rife.mp4): *2.5sec at 25fps using 16 input images*
### Using [Seed Travel](https://github.com/yownas/seed_travel) extension
https://github.com/vladmandic/rife/assets/57876960/22ca5650-a770-4adb-b846-6dc06cdc3b26
[Video](./samples/video.mp4): *9sec at 30fps using 10 input images*
