Rife-App is described as 'AI powered frame interpolator that increases the framerate in set multipliers. Rife-App is the successor to Dain-App but Rife-App can run 25X faster than Dain-App and use way less Vram' and is an app in the Video & Movies category. There are four alternatives to Rife-App for Windows, Linux and Mac. The best alternative is SmoothVideo Project. It's not free, so if you're looking for a free alternative, you could try Flowframes or butterflow-ui.
SVP allows you to watch any video on your PC file with frame interpolation (like you can watch it on high-end TVs and projectors). It increases frame rate by generating intermediate animation frames between existing ones to produce very smooth, fluid and clear motion.
