Wide-band multi-format audio/video recording and production system with frame rate conversion

Abstract

Wide-band multi-format audio/video recording and production system with frame-rate conversion and methods performed by the audio/video production system. In one aspect, a method is performed by a portable video image recording device including an image sensor and high-capacity digital storage means supporting asynchronous access for recording and reproducing. The image sensor receives an input video image and the output of the image sensor is sampled using a sampling frequency of at least 30 megahertz to generate frames of video image data employing a first frame rate and having a first image dimension in pixels. A video program is recorded by processing the frames of video image data and storing video program content in a compressed progressive format using the high-capacity digital storage means. Concurrent to recording the video program, video image data is manipulated in real-time on a selective basis to output video content in an output video format having a second frame rate different than the first frame rate.
