Intra-frame (compression)

Compression that uses just one picture. The compression process only is designed to remove what it considers to be redundant and visually less significant information from within the frame itself. No account is taken of other frames. JPEG and the ā€˜Iā€™ frames of MPEG-2 are coded in this way and use DCT. In an MPEG-2 sequence of frames editing can only be at I-frames as they are the only independent frames.
