Video encoding is the process of converting digital video files from one format to another. Encoding is also known as “transcoding” or “video conversion.” At the time of recording, the device gives the video file a particular format and other specifications. All of the videos we watch on our computers, tablets, and mobile phones have gone through an encoding process that converts the original source video so that it is viewable on various output formats. This is because many device and browser types only support specific video formats.
The H.264 video compression standard , also known as MPEG-4 Part 10, Advanced Video Coding, MPEG-4 AVC or AVC video, is an industry standard for video compression that is one of the most frequently used video formats nowadays.
A codec based on the H.264 standard compresses a digital video file (or stream) so that it only requires half of the storage space (or network bandwidth) of MPEG-2. Through this compression, the codec is able to maintain the same video quality despite using only half of the storage space.
H265, or High Efficient Video Coding, is the new standard video compression that provides even more improvement over H264. H265 provides improved bit reduction of 57% at 1080p and 64% of UHD or 4K compare to H264.
Video recorded on H.265 will only be playable on the device that supports H.265 playback.
