This lossless codec is based on the PNG image format. Each frame can be encoded as-is (I-frame), or can represent a delta from the previous frame (P-frame). In both cases the data is compressed in standard PNG format.

The codec was originally developed to compress subtitles.

The codec supports RGB[A] and YUV colorspaces: In RGB mode every frame is compressed as a PNG image; in YUV mode a frame is stored as 3 PNG images with order Y, U, V.
