H264 is a licensed video compression standard that is necessary in order to obtain a high degree of video stream compression while maintaining good quality. The H264 format has been widely used to record, process and store data from an external surveillance camera. That is, a file with an extension of H264 is essentially a video. The file was developed by Video Coding Experts Group. The specificity of the H264 format is that video data is compressed to a minimum size. Moreover, the resolution settings for video and audio quality are at a high level. The format is innovative. He found widespread use on vehicle video recorders and outdoor surveillance cameras. H.264 is a video compression codec that requests the video container needed to store encoded videos. This is a proprietary video codec that uses highly efficient compression algorithms and delivers great video quality. The main advantage of the H264 format is its high compression ratio when it is necessary to maintain the proper quality of video and audio data. When working with video recorders such as a camera and a DVR, which can be long and even continuous, this is very important if it is not possible to clean the physical memory. For users, the H264 video format is very popular. And therefore, there is practically no problem with playing back an H264 file. It can be opened online. For this, standard Windows tools are used. Say Media Player. Specialized programs are also used.
WebM is an open multimedia file format developed by Google's IT giant. It was first introduced by the developer on May 19, 2010 at the Google I / O conference. Typically, WebM files store video with compression using VP8 technology, as well as audio with compression using Ogg Vorbis compression. The initial developer of VP8 technology is ON2, which Google later acquired. WebM format provides efficient compression and high quality video. The format is supported by Google Chrome, Mozilla Firefox, and Opera. When installing the necessary codecs in Windows, this format is also supported in Internet Explorer.
