IDENTIFY THE FORMATS USED WHEN ENCODING VIDEO

What are Video Encoding Formats? 

Also video file formats (programs & devices) They are methods of optimising digital for different file platforms. There are many different types of encoding formats within videos, as the codec specifies in which the way un-compressed video is stored and saved. It also effects the way it is transmitted between certain files and the way that it is viewed as well.  It is also important for streaming as you want your encoding video to format with as many wide range of devices as possible. For example someone may want to upload professional portfolio videos, he needs to consider the bandwidth of much it will take up on his website etc.

 How Does Video Encoding Work? 

Video encoding is the process of turning non-compressed video audio formats into a form that can be stored and played by a variety of different devices e.g mobiles, televisions, tablets etc. Compression significantly decreases the size of the video file so it's more manageable. Without proper compression, most files will be to large to upload easily. 

Trans-coding refers to the total audio progress from to video to video. It ensures that a video file is fully compatible with another certain platform that it is using. Without trans coding, users will not able to watch the video at all. 

What is a Codec? 

A codec or a (coder/decoder) is a computer/device that compresses and decompresses data.  This is to allow video files to be exported and revived by different online applications. Seprate codecs are used to compress individual audio and video files, but they generally work in the exact same way. Codecs encode files using either lossy compression or lossless compression. Lossy compression simplifies the data in a video file and only keeps the essential parts. So if a video of a flower bed was made pointing out all the pink and purple flowers, depending on the compression type, may end up varying the colour tone of each flower make it seem more dull or bright in colour, than it actually was.

What is a Container?

A container combines an encoded audio stream. The metadata tells the video player how to coordinate different audio and video codecs and may also provide additional elements, such as subtitles or alternate audio streams. Each container supports a different range of video codecs, Other containers are compatible with many types of video codecs and players. 

What are the Common Types of Video Encoding Formats? 

MP4: is a video file format created by the Motion Picture Expert Group. It compresses audio and video separately, which allows MP4 files to retain relatively high video quality after compression. 

MOV: QuickTime Movie (MOV) is a video file format created by Apple. Although it can run on both Mac OS and Windows OS, it is only compatible with QuickTime video players. 

AVI: Audio Video is a video file format created by Microsoft. It is one of the oldest video file container specifications. AVI works with a number of different codecs, which can affect how well it is supported by different operating systems and browsers.
