No matter you're watching videos on social platforms such as Instagram and YouTube, or having a good time with TV series, you might notice these videos are in different resolutions based on different devices. If you're creating a video and want to put it on different platforms or devices, resolution is the thing you'll need to consider. For example, as many phones are capable of displaying HD videos, 1080p is the best resolution for video sharing apps on phones. Some of the computer monitors are 2k or even 4k, you can shoot your video with higher resolution or upgrade the resolution with a video editor. However, if the resolution of your video exceeds the device's capability or social platform's requirements, you'll need to decrease the resolution.
