If you’re using Photoshop Extended to perform color and tone correction in video footage, you may be frustrated by tying Photoshop up for long periods of time rendering video. If so, try offloading the rendering chores to Adobe Media Encoder CS4 or CS5.
Simply save your color-corrected video files as layered .PSDs and open them into the Adobe Media Encoder queue. Here, you can batch encode your videos and be able to work in Photoshop.
Note: The source video files are linked to by the layered .PSD document (just like your NLE). In Photoshop, if you attempt to open a file and Photoshop cannot find the source video, it will give you a warning. In Adobe Media Encoder, that warning doesn’t exist. Instead of getting a completed video, you’ll have a full-length video generated from the video thumbnail frame.
So, the moral of the story is . . . Make sure the hard drives with your source videos are available when using this method; otherwise, you may spend time rendering videos that are useless in your workflow.
