How WEBM compressing works

You may need to compress WEBM video for many different reasons - to save space in the device's memory or to transfer a file over the Internet. In any case, you need a good compressor that will do its job at the highest level. Modern video compression algorithms differ from image compression algorithms with which you may be familiar. The extra dimension and time means that various mathematical and logical methods are applied to the video file to reduce the size while maintaining the video quality. Video compression algorithms look for spatial and temporal redundancy. By encoding redundant data a minimum number of times, the file size can be reduced. Imagine, for example, one minute as the character's face slowly changes its facial expression. It doesn't make sense to encode a background image for each frame: instead, you can encode it once and then refer to it until you know the video is changing. This inter-prediction coding is responsible for artifacts that interfere with the compression of digital video: parts of the old image move with the wrong action because something in the coding has become useless.

A WEBM file is a compressed video saved in the WebM format, an open high quality video standard. It stores video compressed using VP8 technology and compressed audio using Ogg Vorbis compression. WEBM files are commonly used to deliver online video using HTML5. A WEBM file is a video in the open WebM format, which is widely used to broadcast videos over the Internet, including YouTube. The format complies with the HTML5 standard and is a container in which compressed video and audio streams are packed. The WebM file container contains a video stream compressed using the VP8 or VP9 codecs, an audio stream compressed with the Vorbis or Opus codec, and subtitles such as WebVTT may also be present. In fact, the structure of the WebM file repeats the Matroska media container, only in a very truncated form regarding the variety of formats and codecs used in MKV. The file with the WEBM extension is an innovative video presentation format that was released in 2010. The copyright holder of this extension is Google. Native WebM support in Mozilla Firefox, Opera and Google Chrome was announced at the 2010 Google I / O conference. But high video quality and low file weight have already earned him a solid reputation. The format was supported in HTML5 and was originally intended for placement on web pages.
