Every digital video you watch or create has a specific set dimension, typically measured in the number of pixels. For example, if your video is detailed as 1280x720, it refers to the dimensions of the picture, which are 1280 pixels wide and 720 pixels high. The number of pixels contained in each frame is known as the resolution. A video with a high resolution has an increased number of pixels, while a video with a low resolution has a low number of pixels.
A video resolution determines how clear or detailed the video appears. The common type of video resolutions and their pixel sizes include Standard Definition/SD (640x480), High Definition/ HD (1280x720), Full HD (1920x1080), Quad HD (2560x1440), 2K (2048x1080), and 4k (3840x2160). This article will focus on everything you need to know about 4k videos and what you need to edit 4k videos.
What is a 4k video?
A 4k video is a high-definition video with more than four times the resolution of a 1080p HD video. Typically, 4k signifies videos with a horizontal resolution close to 4000 pixels and a vertical resolution close to 2000 pixels. 4K videos are classified into two pixels sizes: UHD (3820x2160), which is supported by TVs/ monitors, and DCI (4096x2160) pixels, mainly used in the film and video production industry.
Comparing the above 4k pixel sizes to the HD pixel sizes (1920x1080), you will see that 4k resolution is around four times horizontally and two times vertically that of HD. This also means 4k videos are four times horizontally and two times sharper and more detailed than HD videos.
Benefits of 4k videos
Quadruple the resolution of HD means superb video, but that's not all. There are multiple benefits of 4k videos over other low-resolutions, especially when editing. 4k videos offer the following exciting possibilities when editing:
Down-conversion to lower resolutions
If you down-convert a video in 4k resolution, it will still be of higher quality than videos recorded in HD or other lower resolutions. Down-converting videos recorded in HD means that you will be getting videos with lower resolutions.
Print quality images
You can print 8-megapixel equivalent pictures from your 4k videos. A 4k video gives you a sequence of frames, and all you have to do is find the most visually arresting moments and screengrab a high-quality picture. You are more likely to print blur images from an HD video as it lacks a lot of detail.
4k video mode is easy to use
When using 4k video mode, video settings such as the brightness level are automatically adjusted according to the shooting parameters.

4k videos are easy to stabilize
Video post stabilization helps analyze motion in footage and eliminate erratic movement when your camera is subjected to bumps or knocks. This helps retain the clarity of your video. In 4k videos, the extra eight margins of pixel help prevent quality degradation during stabilization. The more details the video has, the more materials the stabilizer has to work on.
A 4k video has more colors than other lower-resolutions
4k cameras have more options for bit rates and bit depth, allowing them to collect over a billion possible colors while filming. Having a video rich in colors makes a 4k video look great even after down-converting to a lower resolution.
Drawbacks of 4k videos
Below are some of the main disadvantages of 4k videos:
4k video requires a large storage capacity
4k videos are large due to the high resolution and great depth of color. This means you must have a storage device with ample space to save 4k videos. You might be forced to purchase extra hard drives or memory cards which are expensive.
4k video requires high-speed internet to stream
To view most 4k videos, you must have a minimum bandwidth of at least 25 Mbps. This kind of bandwidth is not available in most places, limiting some people from streaming 4k videos.
4k TVs and gadgets are expensive
To fully enjoy a 4k video, you must have a gadget with a UHD monitor. These types of devices are priced more than those with low-resolution displays.
High Dynamic Range (HDR) defines the color range between the lightest and the darkest tones in a video. The main difference between 4k and HDR is that HDR is more visually impactful than 4k, while 4k delivers more detailed and sharper videos.
When should you film in 4k vs. 1080p
With 4k delivering sharper and more detailed videos, there are still some reasons to shoot in 1080p. The main limitation of having 4k videos is that they require a large storage capacity. Therefore, you can opt to record in 1080p if your memory card is limited in space. Filming in 1080p also proves better for slow motion as you can only shoot at 30 frames per second in 4k.
What to know for uploading 4k videos to YouTube
YouTube ranks as one of the best platforms to share your recorded videos, especially if you are a content creator. It's also not a secret that most viewers enjoy watching a high-quality video on their computer, phone, or TV screen. Poorly shot and edited videos may alienate your viewers, as there are multiple videos on YouTube to choose from.
Therefore, to remain at the top of the game, you must know how to create and upload high-quality 4k videos. Although not all viewers might have a 4k display or have substantial bandwidth to stream 4k videos, having UHD videos ensures that your audience enjoy the best possible experience.
