Rife-App 3.33 – AI video interpolation

Release Year/Date : 2022-11-09
Version : 3.33
Developer : GRisk Developer
Site : https://grisk.itch.io/rife-app
Bit depth : 32bit, 64bit
Interface language : English
Tabletka : not required
System requirements : Intel core duo, GTX 1060, 8 GB ram (works either on the processor or on the video card)
AMD video cards are supported (in test mode).
> If you install in the system folders “C: \ Program Files”, etc., then the program can only be run as an administrator .
This can be enabled in the shortcut settings. Runs fine from other locations.

Size:  1.58 GB

Description :
Rife-App can run 25X faster than Dain-App and use way less Vram. A Nvidia card can still boost the speed of the application, but unlike Dain-App, it can also run on the CPU (slower)
Rife-App take a input mp4/gif/webm/etc and interpolate the frames to make it 2X/ 4X/8X the input FPS.
Designed to convert (interpolate) video (or gif-animations) to video with double frame rate (as well as x4, x8, x16, x32).
The AI ​​will remove duplicate frames and make sure animations are only applied to moving objects and not to the background.
A large number of frames also allows you to create slow-motion effects.
Initially, the author used the DAIN algorithm, but then switched to RIFE (see comparison below) and remade it.
On the topic, I advise you to try the free Flowframes and Waifu2x-Extension-GUI , which have a different algorithm of work.

Rife-App Animation Guide
Introduction
There is no configuration on Rife-App that can handle all inputs, even for animation you may
be able to get better results with the default options for one input and totally different options.
This document is a few tips you can try to get better results for your animation.
You should try this setup in order until you manage to get a result you like.
Test 1:
● Turn on “Animation Mode”, animations usually use the same frame for a few
seconds, this helps smooth that out.
● If you have a low quality input, set Similar frame percentage to 0.99 or even 0.98
(instead of 0.999)
● If your animation is a perfect loop, turn on “Perfect loop”
● Set X2 / X4 / X8 depending on what you want .
● If you are 8X or more, you usually will want to turn on “Smooth interpolation” to focus
more on the original frames.
Test 2:
● Turn on “Animation Mode”
● Set Alternative Interpolation 100%
● Alternative Interpolation usually work better with odd multipliers, so test it with 3X /
5X / 7X etc
Test 3:
● If you like the result of Test 2 but there is still to much artifacts, test it with Alternative
Interpolation 75% / 50% / 25%
● If you like the result, but the motion seen floaty, turn on “Smooth Interpolation”
I am doing PixelArt:
● If you are using a really low resolution animation or pixel-art, you can try to put “Inner
scale” to 2.0 or 4.0, it sometimes improves the result.
I don’t want to alter the animation that much:
● You can try to interpolate at X1, this will only create new frames in places where the
animation is completely still, giving a little more flow to the output.
