Real-Time Intermediate Flow Estimation for Video Frame Interpolation, based on rife-ncnn-vulkan.

This is a port of the VapourSynth plugin RIFE.

• Vulkan device

• AviSynth+ r3688 or later (1 / 2 / 3)

• Microsoft VisualC++ Redistributable Package 2022 (can be downloaded from here)

RIFE(clip input, int "model", int "factor_num", int "factor_den", int "fps_num", int "fps_den", string "model_path", int "gpu_id", int "gpu_thread", bool "tta", bool "uhd", bool "sc", bool "sc1", float "sc_threshold", bool "skip", float "skip_threshold", bool "list_gpu", bool "denoise", int "denoise_tr")

• input
  A clip to process.
  It must be in RGB 32-bit planar format.

• model
  Model to use.
  models must be located in the same folder as RIFE.dll.
  Some of the models have two versions: speed oriented (ensemble=False / fast=True) and quality oriented (ensemble=True / fast=False).

  Default: 5.

• factor_num, factor_den
  Factor of target frame rate.
  For example factor_num=5, factor_den=2 will multiply input clip FPS by 2.5.
  Only rife-v4 model supports custom frame rate.
  Default: 2, 1.

• fps_num, fps_den
  Target frame rate.
  Only rife-v4 model supports custom frame rate.
  Supersedes factor_num/factor_den parameter if specified.
  Default: Not specified.

• model_path
  RIFE model path.
  Supersedes model parameter if specified.
  Default: Not specified.

• gpu_id
  GPU device to use.
  By default the default device is selected.

• gpu_thread
  Thread count for interpolation.
  Using larger values may increase GPU usage and consume more GPU memory.
  If you find that your GPU is hungry, try increasing thread count to achieve faster processing.
  Must be between 1 and the max compute queue count supported by the GPU.
  Default: 2.

• tta
  Enable TTA(Test-Time Augmentation) mode.
  Default: False.

• uhd
  Enable UHD mode.
  Default: False.

• sc
  Avoid interpolating frames over scene changes.
  This cannot be true when sc1=true.
  Default: False.

• sc1
  Blend frames (average) frames over scene changes.
  This cannot be true when sc=true.
  Default: False.

• sc_threshold
  Threshold to determine whether the current frame and the next one are end/beginning of scene.
  Must be between 0.0..1.0.
  Default: 0.12.

• skip
  Skip interpolating static frames.
  Requires VMAF plugin.
  Default: False.

• skip_threshold
  PSNR threshold to determine whether the current frame and the next one are static.
  Must be between 0.0..60.0.
  Default: 60.0.

• list_gpu
  Simply print a list of available GPU devices on the frame and does no interpolation.
  Default: False.

• denoise
  Whether to return only the interpolated frames.
  Default: False.

• denoise_tr
  Frame radius.
  For example, denoise_tr=1 means frames n-1 and n+1 are used.
  Must be greater than 0.
  Default: 1.

• Requires Boost, Vulkan SDK.
