Samsung Galaxy AI Instant Slow-mo Feature

Samsung Galaxy S24 Ultra is equipped with Galaxy AI-derived Instant Slow-mo feature. The company says the Galaxy S24 series uses powerful AI Frame Rate Conversion (FRC) technology to achieve these slow-mo effects.

Galaxy AI-powered Instant Slow-mo requires no prior setup for the capturing process. Thanks to intelligent AI Frame Rate Conversion, the Galaxy S24 series can transform HD 24fps to UHD 60fps videos into slow-mo epics.

FHD 240fps to UHD 120fps slow-mo videos can go further still with super slow motion. By generating new intermediate frames of movement based on the video that is already there, Instant Slow-mo achieves silky-smooth, highly detailed replays every time.

The South Korean tech giant just confirmed that starting in late March, Instant Slow-mo will expand to support 480×480 24fps videos, allowing users to create social media-friendly video content with ease.

To achieve these slow-mo effects, the Galaxy S24 series uses powerful AI Frame Rate Conversion (FRC) technology that is as follows:

First, AI FRC takes every two frames from the video as it was originally recorded and uses a deep learning model to analyze and extract motion information.

Extracting this information establishes the differences between frames and helps AI FRC interpolate intermediate frames that give the video slower motion.

This process is carried out twice — in both square dimension and reverse dimension — to boost the accuracy of the new, additional frames that have been generated.

Then, two fusion processes are carried out:

Fusion Map and Residual. Fusion Map detects and extracts 2D outlines to help detect motion differences between frames, while Residual adds extra corrections and post-edits to minute details for enhanced accuracy. This allows the feature to create accurate intermediate frames extremely quickly.

When this is completed, the outputs of these two processes are fused one last time to render the final, AI-generated intermediate frames that give the video both fluid slow motion and meticulous detail.
