Full HD camera vs. 4K camera: What’s the difference?

The difference between full HD cameras and 4K video cameras

A 4K camera, otherwise known as Ultra HD, captures images at a resolution of 3,840 pixels wide by 2,160 pixels tall. The term “4K” relates to the horizontal resolution, which is essentially four times the standard high-definition (HD) resolution. Consequently, this high resolution delivers images with remarkably sharp detail and superior clarity.

On the other hand, Full HD, also known as 1080p, captures images at a resolution of 1,920 pixels wide by 1,080 pixels tall. The “p” in 1080p stands for ‘progressive scan,’ which is a method of displaying, storing, and transmitting moving images where all the lines of each frame are drawn in sequence.

The key features to look for in a 4K video camera

When shooting in 4K, users will want to make sure they are capturing every detail of their subject. To do this, it is important to have a 4K video camera that has the right features. This includes high resolution, fast framing, and good low-light performance. 

Now that we know what 4K is all about, let’s take a look at seven key features to consider when selecting a 4K video camera.

Image sensor

Image sensor for 4K video camera

The image sensor is the camera’s eye, capturing the light and color details needed to produce the final image or video. A larger image sensor can amass more light, which in turn translates to more detailed and vibrant video capture. When looking for a high-quality 4K camera, businesses should consider one with at least an APS-C-sized sensor (1.6x crop factor), for superior imaging.

Frame rate

In videography, frame rate refers to the number of individual images that a camera records per second. A professional 4K camcorder should provide a minimum of 30 frames per second (fps) for a cinematic look, going above that, up to 120 fps, allows for ultra-smooth motion capture.

Lens compatibility

The camera’s lens is a critical component that affects not only zoom and focus capabilities but also the quality and clarity of the captured image. It’s advisable to opt for a full-frame 4K camera compatible with interchangeable lenses, allowing for the flexibility to switch between prime lenses (fixed-focal length) and zoom lenses depending on the shooting needs.

Image stabilization system

A professional image stabilization system is designed to reduce image blur caused by camera shake or movement. The ideal 4K video action camera should have a high-grade image stabilization system that is able to compensate for movement up to five stops of shutter speed – if not more – enabling photographers to use a slower shutter speed without the risk of blurred images due to camera shake.

Audio quality

The built-in microphone of a professional 4K camcorder should be capable of encoding high-quality audio that doesn’t degrade or become garbled. A camera setup that supports an external microphone can further boost audio quality. Cardioid or omnidirectional microphones are excellent for capturing ambient sounds, particularly in quiet scenes like those seen in nature documentaries.

Battery life

Importance of battery life for 4K video cameras

A 4K video camera with a robust battery life is essential for continuous shooting. Preferably, businesses should look for one compatible with in-camera USB charging. As an added advantage, consider features that support fast charging or rely on external power banks, as well as feature power-saving modes, like auto-off display.

Storage capacity

Storage capacity is another crucial factor since 4K videos consume more space compared to lower-resolution videos like 1080p or 720p. Most mini 4K digital cameras accommodate SD, SDHC, or SDXC cards, which can house up to 2TB of data or more. Some portable 4K camcorders even have multiple card slots for simultaneous or sequential recording. A good rule of thumb would be to reserve at least 45GB of storage space for each hour of 4K video footage.
