More information on frame types can be found here. In most cases this means many P-frames with I-frames interspersed at regular intervals and where drastic visual changes in the video occur. When a video is encoded, or compressed, a combination of these types of frames are used. Instead of storing full pictures these P-frames and B-frames contain data describing only the differences in the picture from the preceding frame, and/or from the next frame, this data is much smaller compared to storing the entire picture - especially in videos where there isn’t much movement. To do this most formats don’t store the entire image for each frame.įrames which store an entire picture are called I-frames (Intra-coded), and can be displayed without any additional information.įrames which don’t contain the entire picture require information from other frames in order to be displayed, either previous or subsequent frames, these frames are called P-frames (Predicted) and B-frames (Bi-predictive). Modern compressed video files have very complex methods of reducing the amount of storage or bandwidth needed to display the video.

In some cases the term datamoshing is used perfect Replica Watches best quality to describe this process applied to any type of media file - I like to think it applies solely to video since it results in moving images being moshed together.
