What is Encoding?
Encoding – is a procedure of data preparation in which information is changed over into a specific organization for simple transmission and capacity purposes.
At the beginning of the computerized video, video documents were all RAW video. This implies video documents were an assortment of still photographs. For a video recorded at 30 edges for each second, you had 30 photographs for every second of the film. That is 1800 pictures for every moment of the video. Thus, video record sizes were gigantic.
The main reasonable arrangement was to pack these recordings, yet the quality was lost through this procedure.
Specialists created video encoding which gave an approach to pack these records without trading off the quality.
What is Video Compression?
Video pressure is utilizing encoding to diminish the size of a computerized video record.
It dissects the substance of a video to diminish the general record size by figuring out which casings are basic and which can go. In the event that two casings are essentially indistinguishable, you can dispose of the information for one edge and supplant it with a reference to the past edge. In this straightforward model, you can decrease your video document size by around 50 percent.
A wide range of video pressure use varieties of this procedure to diminish document sizes. At the point when we talk about video encoding, in any case, we’re alluding to a particular sort of video pressure.
How Does Video Compression Work?
Video pressure ordinarily occurs at the camera level. For instance, cell phones, purchaser grade camcorders, and most expert camcorders record video in the H.264 video codec group.
This implies, as the camera is recording, the RAW pictures from the video sensor encode progressively, normally utilizing the H.264 group. This compacted—or encoded—video at that point records to the capacity on the camera.
What are Codecs?
The devices that are utilized for video document pressure and playback are designated “codecs.” Codec represents coder and decoder (co/dec). A codec is a gadget or PC program which encodes or deciphers a computerized information stream or sign. They pack crude video and sound documents and make them littler.
Various gadgets have various sorts of help for different codecs. Have you at any point downloaded a video at that point attempted to play it to find that playback fizzled? You probably won’t have had programming fit for playing back video encoded with that codec.
Today, the most widely recognized video codec is H.264. Pretty much every gadget in presence underpins this convention and it’s basic for use with online video. Be that as it may, there are a few different codecs accessible, including MPEG-2, HEVC, VP9, Quicktime, and WMV.
