Abstract: There is disclosed herein an electronic system for the production of high-definition color motion pictures for theatrical and television use. The system employs digital video techniques wherein electronic analog video color signals are digitized, and the digital signals are stored. A scene may be played back immediately during shooting for monitoring purposes or recorded subsequently on film for facilitating editing. Desired portions, such as frames or scenes, of the stored digital color picture information may be selected and assembled, and operated upon to provide special effects, to achieve suitable editing, the resulting pictures again being recorded digitally. This resulting recording may be reproduced and electronically color corrected and enhanced and then converted back to analog form for ultimate visual presentation. The analog signals may be used to generate a color film, or the digital signals before conversion may be converted to different scan standards for presentation according to various television scan standards.
