Video Encoding

Video encoding is used to convert video data into formats that then can be used on other applications, devices and web based sites. Encoding affects the quality of the video and the file type it is formatted as (Coconut, No Date). The various formats have their own different qualities that make them compatible with particular applications and uses. It is important to render the video in the right format to suit the purpose and use of the video as each format has their advantages and disadvantages.

In Premiere this is done by opening up the export option tab, pressing Ctrl + M. The top option is the format the video will be rendered as ad the one below is the resolution, which also affects the video quality. For example, a resolution of 720p contains 1280 pixels in length and 720 pixels in height. Whereas 1080p contains 1920 pixels wide and 1080 pixels high (Newton and Barraclough, 2016). This would then make the video rendered at 1080p appear sharper and of a higher quality due to the extra amount of pixels. As well as the format and resolution, the frame rate is another important factor that is a part of the encoding process. The more frames per second result in a smoother visual output, whereas fewer frames result in a jumpy effect. The average frames used is 25-30fps which will provide a smooth finish on the video.

Some of the most common formats used are MP4, WMV, FLV and MOV (Motion Elements, 2013).


Mp4 was produced by the International Organization for Standardization in 1998 (Thomas, No Date), (Bytescout, No Date). The file extension is .MP4 and is compatible with Windows, Linux and MAC platforms (Easy HTML5 Video, No Date).

An advantage of this file type is that it is supported on most applications and for online use. It not only renders the visual output but also audio, still images and subtitles, making it beneficial for most projects. The only significant disadvantage is that it is not easy to edit.

MP4 is a lossless file type. This means that it retains original information but is still compressed to reduce file size, which then takes up less disk space. It is not compressed as much as MP3 files but still enough to make it usable for the web (Bytescout, No Date)). The final output is of a high quality and can maintain this quality when used on different sized displays, such as phones and tablets.
