Last month, Samsung launched its Galaxy S24 series with a range of innovative features, including Instant Slow-Mo. This feature enables users to watch recorded videos in slow motion simply by long-pressing on them, eliminating the need to record in slow motion or manually edit the effect. Initially exclusive to the Galaxy S24, Galaxy S24+, and Galaxy S24 Ultra, Samsung is now extending Instant Slow-Mo to older devices.
On February 13, a moderator in Samsung's official South Korean community forum announced the expansion. After sharing the details of the feature, they revealed that eight older smartphones would soon support Instant Slow-Mo. These include the Galaxy S23, Galaxy S23+, Galaxy S23 Ultra, Galaxy Tab S9, Galaxy Tab S9+, Galaxy Tab S9 Ultra, Galaxy Z Flip 5, and Galaxy Z Fold 5.
The post explained that the feature requires a powerful Neural Processing Unit (NPU) and Graphics Processing Unit (GPU) with a minimum processing speed of 16.6 milliseconds for 60fps videos. All eight listed smartphones feature the Snapdragon 8 Gen 2 chipset, meeting the necessary threshold. As a result, it's unlikely that phones with older or less powerful processors will receive this feature.

Described the Instant Slow-Mo as "time zoom" in the post, the moderator explained just like spatial zoom in still images, where users can stretch the image to see finer details.
For the slow-motion feature, the company stretches the time taken between each frame of the video, enabling users to observe finer motion details. While no specific timeline was mentioned for the feature's arrival on older devices, reports suggest it could arrive with the One UI 6.1 update anticipated next month.
Currently, Instant Slow-Mo supports 8-bit videos ranging from 720p to 8K resolution in MP4 format. Samsung aims to enhance the feature, potentially adding support for 10-bit videos at 480p resolution and in MOV format.
