The Galaxy Z Fold 5 can record better 8K and Super Steady videos.
Galaxy Z Fold 5 can record videos at 8K 30fps and QHD 60fps (Super Steady)
The Galaxy Z Fold 5 supports 8K 30fps video recording, just like the Galaxy S23 series. It is an upgrade from the 8K 24fps video recording available on the Galaxy Z Fold 4. Thanks to the 30fps frame rate, videos look fluid and smooth. Even the Super Steady video recording mode offers better video quality thanks to a higher resolution. Like the Galaxy S23, the Galaxy Z Fold 5 can record ultra-stabilized videos in QHD resolution and at 60fps.

All of these improvements in video recording generally boil down to the new Snapdragon 8 Gen 2 For Galaxy chip used in Samsung's new foldable phones.
