What is a 4k video camera?

4k Video cameras take photos and video with resolution that’s equivalent or higher than HDTV.

In other words, they can capture images that have a resolution of 4064 x 2160 pixels, or 4k.

You can also call this resolution “FullHD” in the resolution-coding business. This comes from the fact the new generation of HDTV is 4k.

It may not sound that much higher than that, especially if you’re a TV owner with a large HD set that doesn’t support upscaling beyond 480p.

To help explain the difference, there are a few basic principles to keep in mind.

How To Use Video Capture

Video Capture can be made using many options including digital cameras, camcorders, camcorders with a 4k video recorder, or an external recorder that uses your smartphone or tablet to feed video data to your camera.

For instance, a DSLR camera can capture your video using:

A wireless interface, such as the Wi-Fi on your smartphone

One or 2 USB ports

A HDMI port

Another video-recording option would be video shot with a digital cinema camera. This can include:

A Wi-Fi connection

A Wi-Fi/Bluetooth connection

You can also use your smartphone to record video, even at a lower resolution, although it will be less than the output produced by the older, Wi-Fi-based cameras.

Video Capturing on a smartphone

If there are 3rd party apps that you use to take photos, videos or video of events, these are all video-capturing options you probably know about. Most smartphones have Wi-Fi or Bluetooth connectivity for this purpose.

There are 3 basic things people do with cameras:

Put it in a case

Record video

Record audio

Most smartphone cameras can’t record video, nor can 3rd party apps like Blackmagic Design’s VSCO Cam.

But they still have the potential to capture video and audio in ways that you wouldn’t normally use on a camera you buy for video or audio.

Here’s an analogy I learned in college about why your smartphone can capture video: imagine if you dropped your TV remote in a cup of hot water and the hot water just kept boiling.


Then you had to take it out and find it. That’s what you’d have to do when using your smartphone
