Video codec developed by Actimagine, originally intended to playback hq-video on mobile phones (also used on Nintendo DS console.) Encoded files need to be converted to the proprietary .mo container format first. Supports videos up to 240 pixels wide.
An opensource decoder for the format based on reverse engineering exists - https://github.com/Gericom/MobiclipDecoder
The format is based on H.264 but it uses different variable-length codes, halfpel-only motion compensation, fixed amount of reference frames, and 8x8 IDCT for luma.
A high-resolution desktop version is also available (MOHD FOURCC).
