TABLE OF CONTENTS Although Photoshop is not a video editing application, there are several unique aspects to video images that can be addressed with Photoshop and Bridge.
Bridge can be used as a manual demultiplexer to sort multiple camera views and isolate the camera views of interest.
Photoshop can be used to deinterlace video, correct pixel aspect ratio, and perform frame averaging for noise reduction of image sequences. In addition to these capabilities, Photoshop CS3 Extended has the ability to import several movie formats and apply most filters and adjustments to entire sequences.
Multiplexed video is common from security camera systems. The process of multiplexing is to record several cameras onto a single videotape or hard drive. Systems that record to hard drives should have demultiplexing capabilities in their software, so the need to demultiplex video in Photoshop is restricted to video from analog systems. I find that Bridge is an excellent place to demultiplex video when there are 1,000 frames or fewer. When there are more frames, the nonlinear systems that offer demultiplexing features, such as Ocean Systems's dPlex Pro, are more efficient.
Once you have exported the still image sequence from your nonlinear editing system, the process is to simply navigate to the folder of images in Bridge and sort the relevant camera views into new folders. Each folder is a single camera view, and it is easy to verify that only the relevant images are used and that no relevant frames were missed.
