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.
MP4 is an abbreviation for MPEG-4 Part 14. It can also be called MPEG-4 AVC. In this case, the abbreviation AVC (Advanced Video Coding) is an advanced video encoding. By the name of the format, it is easy to guess that it is necessary for working with video files. The format was first proposed in 1998. Since then, MP4 is considered one of the most common file formats used to store and transmit multimedia. MP4 is a container format that provides the ability to combine audio, video, subtitles and pictures in one file. It is also suitable for posting rich content. Say three-dimensional graphics, menus and interactive features. There are many portable players and other devices that play MP4. For this, a PC or laptop is also quite suitable. The MP4 format is a robust application that needs relatively low performance. And therefore, users could use such a tool for their own purposes. This tool has found wide application, as the technology for the production of more and more powerful devices, both portable and desktop with a large hard drive capacity, is constantly evolving. Due to the fact that the speeds of various types of connections to the global network are increasing, MP4 has become more affordable. It acts like the MP3 format, although it is more complex. The format compresses files and remains high-quality.
