What is video encoding?
Video encoding is the process of converting digital video files from one format to another. Encoding is also known as “transcoding” or “video conversion”. During recording, the device provides a video file in a specific format and other specifications. If a video owner wants to post a video, they need to consider the different devices the video can be played on.
All the videos we watch on our computers, tablets, and mobile phones have gone through an encoding process that converts the original video so that it can be viewed in a variety of output formats. This is because many types of devices and browsers only support certain video formats. Often times, the goal of a video editor is to ensure compatibility with different formats.
Digital video can exist in many different formats, each with specific variables such as video containers (.MOV, .FLV, .MP4, .OGG, .WMV, WebM), codecs (H264, VP6, ProRes), and bitrates (in megabits or kilobits per second). Different devices and browsers have different specifications, most of which are associated with one or more of these variables, and other variables.
When encoding a video, you should consider (a) the original source format and method of video capture, (b) any subsequent encoding operations that may have been performed on the video source, and (c) the required output formats.
The container is designed to store different types of data. This includes audio, video, and sometimes subtitles. They are like the boxes in which we put our sweets. Note that the biggest difference between these containers is the support they provide for the basic bits of information. Different containers provide support for different audio and video compressions. Some will allow multiple audio tracks or subtitles to be included, while others will allow only one or none. If you want to add subtitles to an AVI or WMV file, you may need to burn them to the image. Video / Audio Codecs The actual difference between most video files depends less on the container used, but more on the video or audio codec in the container. The video codec determines how the information is processed. Some of the most popular video codecs include DivX / XviD h264 / x264 FFMPEG Theora You must remember that the content or how the content is stored is not always determined by the container, although it is often limited (for example, some containers support multiple streams audio, while AVI only supports one). As a result, there are several different combinations available between containers and codecs.
