 # RIFE
-RIFE function for VapourSynth, based on https://github.com/hzwer/Practical-RIFE.
+Real-Time Intermediate Flow Estimation for Video Frame Interpolation, based on https://github.com/hzwer/Practical-RIFE.
 
 
 ## Dependencies
 - [NumPy](https://numpy.org/install)
-- [PyTorch](https://pytorch.org/get-started), preferably with CUDA. Note that `torchaudio` is not required and hence can be omitted from the command.
-- [VapourSynth](http://www.vapoursynth.com/)
+- [PyTorch](https://pytorch.org/get-started) 1.13.0+
+- [VapourSynth](http://www.vapoursynth.com/) R55+
+
+`trt` requires additional runtime libraries:
+- [CUDA Toolkit](https://developer.nvidia.com/cuda-toolkit)
+- [cuDNN](https://developer.nvidia.com/cudnn)
+- [TensorRT](https://developer.nvidia.com/tensorrt)
 
 
 ## Installation
