If you ever wanted to understand video encoding, this is the intro for you. Video encoding is the process of converting digital video from one format to another, which can be streaming online or for other use. There are a range of formats that may be encoded to make this process possible. The most common formats are MPEG-4 and H.264/MPEG-4 AVC. Video encoding does not have just one standard conversion formula, but there are three broad categories that are used commonly: lossless compression, lossy compression, and transparent compression techniques. Video encoding can be done by software applications, but it is most commonly done by media engines. These engines are the main components for video encoding. There are a plethora of integrated tools available to edit video, whether for commercial or personal use. Some media engines have the ability to output to different formats, whether it be an H.264/MPEG-4 AVC encoded YouTube video or an H.265/HEVC formatted Blu-ray disc. Performing video encoding can be done manually, but there are even more complex software packages that automate the process for professional users, just as there are also free and open source packages available for home use. The dictionary definition of video encoding is: With this basic understanding of what video encoding is, we will dive into the topic further with how it's done and why it's done. One of the most common ways that users encode video is for online use, such as YouTube or Facebook or other forms of social media. Transcoding (conversion to a different format) and streaming (delivery across networks) are two types of digital video transmission, which both require encoding. Streaming over the internet requires a large amount of bandwidth, so compressing encoded content can help with efficiency in this case. There are three basic services that come into play when streaming: live streaming and on-demand video and file delivery. On-demand video is when users request video to be delivered to their computer or mobile device. File delivery refers to the transfer of information using a protocol, such as FTP or HTTP. Live streaming refers to the real-time transmission of media over the internet for viewing. Both on-demand and live streaming require encoding for delivery across networks, so they are similar in many ways, but live streaming's real-time aspect makes it more demanding on network bandwidth and quality due to lower latency requirements. These factors make live streaming a more challenging type of encoding compared to on-demand. In addition, there are different formats available based on resolution and frame rate for each type of encoding format. Lossless compression is commonly used for editing on high-quality video, especially with large file sizes. The process of lossless compression reduces unnecessary data to remove errors, so the image is very similar to the original. This is ideal for editing videos, as it prevents any errors or unwanted artifacts from appearing on screen. Lossless compression takes one high-quality image and transcodes it into a more compressed format without changing its quality significantly. If changes are needed, then a new encoded version will need to be created through another type of encoding, such as lossy or transparent encoding. Quality compression will keep quality intact, but lower bit rates may impact resolution unless they are scaled appropriately. eccc085e13
