How do I do this? -34- I simply want to create a JPEG-compressed movie which is compatible with the Cosmo Compress board. I don't want to write my own program. How do I do this? -35- I want to capture a still image from video using a shell script. The Capture tool doesn't seem to be appropriate because it waits for the user to click the mouse button. How can I accomplish this?
