Pre-interpolation

Name

pre-interpolation.enabled

range

yes, no

default

no

RIFE raises the frame rate first, and the svp engine interpolates the result from closer frames. The render is slower. The section shows only when Engine is svp.

The previews interpolate a 60 fps copy of the clip to 240 fps, and recorded shows the 240 fps clip. Here, svp alone loses the sword, and pre-interpolation keeps it.

Name

pre-interpolation.fps

range

2 to 100000, or 1x to 1000x

default

2x

Sets the frame rate that RIFE makes. Enter a rate in fps, or a multiple of the clip rate such as 2x or 2.5x.

A higher rate gives svp closer frames and costs more time. At the interpolation frame rate, here 4x, RIFE makes all the interpolated frames.

Name

rife.backend

range

vulkan, tensorrt

default

vulkan

Sets how RIFE runs on the GPU. The vulkan backend works on any GPU with Vulkan. The tensorrt backend needs an NVIDIA GPU and the TensorRT component. When TensorRT is not ready, interpolini uses vulkan and shows a warning.

The frames of the two backends are almost identical (within noise), as the difference shows.

Name

rife.model

range

rife-v4.6, rife-v4.15-lite, rife-v4.22-lite, rife-v4.25, rife-v4.25-lite, rife-v4.26

default

rife-v4.6

Sets the RIFE model. The list shows the installed models, and Get more models opens Components.

These examples run RIFE alone at 4x. Each model breaks the sword edge in its own way, and here rife-v4.15-lite blurs the right edge. No model is best for every clip, so compare them on yours. The backend and the model also apply to the rife engine.
