Limelight
4K Video Recording / Resolution
4K recording captures video at roughly 3840 by 2160 pixels, about four times the detail of 1080p.
4K recording refers to capturing video at a resolution of roughly 3840 by 2160 pixels, the consumer Ultra HD standard. That is four times the pixel count of 1080p Full HD, packing far more detail into every frame. The extra resolution translates into sharper edges, cleaner text, and more room to crop or zoom without the image turning soft.
The tradeoffs are larger files and heavier processing, which is where hardware-accelerated encoding and a capable display come in. For screen recording specifically, high resolution is especially valuable because on-screen text and fine UI elements are unforgiving; at lower resolutions they can blur, while 4K keeps interface details legible.
Limelight records natively on modern Macs, whose Retina displays are well suited to producing crisp, high-resolution captures. Combined with auto-zoom into every click, a high-resolution recording lets viewers read fine details clearly, and the finished result exports to a shareable MP4.

FAQ
- How much sharper is 4K than 1080p?
- 4K has about four times the pixels of 1080p, so text and fine UI elements stay crisp and you have more room to crop or zoom.
- Why does resolution matter for screen recording?
- On-screen text and small interface elements are unforgiving; higher resolution keeps them legible where lower resolutions would blur them.
- Can Limelight record at high resolution?
- Limelight records natively on modern Retina Macs, producing crisp high-resolution captures that export to a shareable MP4.
