4K Video
4K video refers to video recording or playback at a resolution of around 3840 × 2160 pixels, which is four times the detail of Full HD (1080p). This results in sharper images, more visible details, and overall better clarity.

Key Benefits of 4K Video

Higher detail and sharpness – Every frame has more pixels, making the video clearer and more lifelike.

Better for editing – More resolution allows for cropping, zooming, or stabilizing footage without losing quality.

Future-proof – Works perfectly on modern 4K TVs, monitors, and projectors.

Improved color and depth – Often paired with HDR for richer colors and better contrast.

4K Video in iPhones
Most recent iPhones can record 4K video at 24, 30, or 60 fps. Some models also support Dolby Vision HDR for improved dynamic range. 4K video recording uses more storage — around 350–400 MB per minute at 30 fps.
