One of the Galaxy S24's coolest features is headed to older Samsung phones

Instant Slow-Mo takes almost any video and makes it slow motion. Now it's not limited to the S24.

When the Samsung Galaxy S24 debuted last month, one of the coolest features was Instant Slow-Mo, which turns a recorded video into a slow-motion video, essentially eliminating the need to record in slow motion like other phones.

Users can long-press on a compatible video in the Galaxy S24 gallery, and the phone -- using the power of AI -- will generate new frames and apply a slow-motion effect.

Now, some older Samsung phones are getting in on the slow-motion fun.

According to a post on an official Korean Samsung community forum, Instant Slow-Mo is soon rolling out to older devices, including the Galaxy S23 series, Galaxy Tab S9 series, Galaxy Z Flip 5, and Galaxy Z Fold 5.

The same post also noted that future software updates would bring improvements to the feature, including compatibility with more video formats and resolution types. Right now, Instant Slow-Mo is only available on 8-bit videos shot in 720p to 8K and MP4.

Diving into the technical side of things, the post explained that because the feature uses both the phone's NPU and GPU, and because it requires a device that can process things at 16.6 milliseconds, phones older than those listed would be ruled out.

Samsung says the feature will work exactly like it does on the S24, with a long press on a video "naturally" slowing it down. The slow-motion video can then be edited and saved separately from the original. 

Instant Slow-Mo joins Circle to Search, Live Translation, Photo Assist, and other AI features that originated on the S24 but are headed to older devices. 

An exact timeframe for a rollout wasn't given, but there's a good chance this will arrive along with several other features in next month's One UI 6.1 update.
