The Mscope process allows effective and efficient digital high-definition (HD) recording of 4 times 3 originated pictures, maintaining the same horizontal resolution while utilizing multiple HD frames (with native 16 times 9 aspect ratio) for storing additional vertical information. Therefore, Mscope allows straightforward digital HD storage of anamorphic images originated with conventional 35mm film anamorphic lenses, or full frame images originated with conventional spherical film lenses, via a 4 times 3 aspect ratio imaging sensor, using readily available HD recorders. Equally, Mscope allows digital HD recording of digitally scanned film frames originated within 4 times 3 aspect ratio frame formats. This invention can also be applied for effective mastering, exchange, presentation, distribution, exhibition, and archiving of anamorphic (and full frame) content, using industry standard HD-compliant equipment. The first practical implementation of the Mscope process is on the Arriflex D-21 film-style digital camera. Its implementation allows anamorphically captured images to be recorded as a dual HD signal. This paper details the implementation of Mscope and how it provides an effective alternative to existing acquisition and Digital Intermediate (DI) workflows, allowing the use of available HD recorders and other HD equipment (which comply with industry established standards) for production, post-production, and exchange of content shot with anamorphic 2.40:1 or full-frame (open gate) aspect ratio frame formats.
