Usually, when we watch videos on YouTube, we are contented with the default video that is first played. Meanwhile there are different levels of quality in this video, the HQ and the HD. First of all, what do these mean or stand for? HQ stands for High Quality, while HD represents High Definition. When you view a video in HQ, it will give a better quality than the standard video. The video will appear finer, and it has an increased bitrate. When videos are viewed on HD, they take the resolution that is used on TVs.
A standard video has a resolution of 480p, but HD videos have a 720p at minimum and 1080p at maximum resolution. HD videos are usually slow on connections, especially if they are of big resolution. That will result in a larger file size and more consumption of connection subscription. Typically, HD videos are better than HQ videos, which is also better than the standard videos.
