Encoding Processes can be found in both image and video files, mostly files directly created by a photo or video cameras like MP4, MOV, and camera raw images. It is also known as “encoding method”.
Video and image encoding is used to prepare photos and videos to be displayed in a way that most computers and software, as well as browsers, can support. This is often necessary because not all videos can be watched in all video players, and not all image viewing software is able to open certain image files. Thus, the high quality, original files have to undergo certain changes with regard to codecs, display and others to be made viewable by a broader audience.
There are different Encoding Processes available to encode a video or image and make it viewable. The information displayed under this metadata in your file shows the method used in the particular file. This means, if an Encoding Process is revealed when checking your file for hidden data, you know that it has been encoded in order for you to open and view or watch it.
