Resolution and Compression

Hello Everyone,

Its Josh here from Loveridge Designs, this week on “Getting into it with Loveridge Designs” We are going to cover resolution and compression.

Video resolution in a display device refers to the number of distinct pixels that can be displayed in each dimension. It is usually quoted as width× height; In this case “1920 × 1080″. 1920 refers to the width and 1080 refers to the height that the display can show in pixels. A display resolution is controlled by factors like the cathode ray tube and flat panel display which are internal parts of digital televisions and computer monitors.
There are three main types of video resolution: Standard Definition (SD), High Definition (HD) and Ultra High Definition (UHD). The most popular standard resolutions are 640×360 and 640×480 for video, and 720×480 and 720×576 for DVD. HD video usually has a resolution of 1280×720 (720p) or 1920×1080 (1080p, is also known as Full HD). Ultra High Defintion presents native video at a minimum resolution of 3840×2160 pixels and upwards and is also referred to as (4K)

In video resolution, Sometimes their will be data limits in place For example, when you upload a video to your mobile phone from a computer, you may have to reduce the resolution of the video. Increasing video resolution does not have a very positive effect because the quality does not actually change even though the video resolution is increased, but the video file size would certainly increase. Nevertheless, these changes can sometimes be necessary. If you want to burn or copy a video (for example a 320×240 video shot on your phone) to a DVD, you will need to increase the resolution because DVD standards require the video to have a resolution of at least 720×480.


On the other hand, video compression refers to the process of reducing the amount of data in a certain video. Normally, it is achieved by reducing and eliminating unnecessary data from the video. When you can not store a video file because it is too big or requires too much storage space, the importance of video compression is found. This is a standard instance in which video compression is used.
The latest standard in video compressing is High-Efficiency Video Coding (HEVC). This can double the amount of data compressed while retaining the same level of video quality. It supports 8K UHD resolution up to 8192 x4320 and can alternatively provide substantial video quality at the same bit rate. We have discussed codecs in a previous video so please feel free to check that out.

As you can see, both video resolution and video compression have their own part to play in the production process and they can have a major impact on the viewers experience of your video.

Thank you very much for taking the time to watch the video i hope you found it both informative and engaging !
Until next time!
