The format that you use dictates how the input video should be processed. What are Encoding Formats?Īn encoding format is a type of technology that is used to facilitate the encoding process. This compressed (or encoded) video is then recorded to the storage on the camera. This means that, as the camera is recording, the RAW images from the video sensor encode in real-time, typically using the H.264 codec.

For example, smartphones, consumer-grade camcorders, and most professional camcorders record video in the H.264 video codec. Video compression typically happens at the camera level. When we talk about video encoding, however, we’re referring to a specific type of video compression. In this simple example, you can reduce your video file size by about 50 percent.Īll types of video compression use variations of this process to reduce file sizes. If two frames are basically identical, you can get rid of the data for one frame and replace it with a reference to the previous frame. It analyzes the content of a video to reduce the overall file size by determining which frames are essential and which can go. Video compression is using encoding to reduce the size of a digital video file. The efficiency of your decoder largely contributes to the latency of your stream. Box top sets and consoles are also considered decoders. In the context of online video streaming, the video player serves as a video decoder. Decoding is actually the opposite of encoding since it is the process of unpacking the data that has been compressed for transmission. What is Decoding?ĭecoding is an important part of encoding. Engineers developed video encoding which provided a way to compress these files without compromising the quality. The only sensible solution was to compress these videos, but the quality was lost through this process. As a result, video file sizes were massive. For a video recorded at 30 frames per second, you had 30 photos per second of footage. This means that video files were a collection of still photos. In the early days of digital video, video files were all RAW video. That’s similar to how RAW video files work. Photos are put together in a way that seems to move when you flip through the page quickly. It is easier to understand what encoding is when you think about it in terms of a more tangible comparison. “In video editing and production, video encoding is the process of preparing the video for output, where the digital video is encoded to meet proper formats and specifications for recording and playback through the use of video encoder software.” What Does Encoding a Video Mean? Here’s a definition of video encoding that summarizes this well: In the most basic sense of the term, video encoding is converting RAW video files to digital files so that they are not saved as individual images but as fluid videos.Įncoding can also be used as an umbrella term to describe similar processes relating to altering the size of a video file. What is Video Encoding? Also called video conversion, video encoding converts a given video input into a digital format that is compatible with most types of Web players and mobile devices.

How to do Multi-Bitrate Video Encoding on Dacast.We will talk about encoding, video compression, encoding formats, transcoding, and more. In this post, we’re going to break down video encoding for live streaming and talk about the importance of each moving part. This technology has made it possible to stream video over the internet, both in real-time and on-demand. Video encoding was brought to life as a solution to aid in this technological transition.
