Using the Quick Cam Pro
We have two models of the Quick Cam Pro digital video camera - one that runs from the serial port of the computer and the other from the USB. Although the optics of the two cameras seem comparable, I much prefer the older camera because the software provides much greater flexibility for making movies. The following instructions are for the two different versions.
Serial Port Version:
This camera/software can create time lapse movies using a Picture Mode or Movie Mode. The major difference is how the final product is constructed. In the Picture Mode, the camera takes a series of separate JPEG images at various time intervals. The images are then "stacked" to make an animated video, much like flipping through the pages of a flipbook. The animated movie can be compiled from the separate images with a program like Paint Shop Pro 6 or ImageJ. The movie mode will create the movie in an .avi format. The advantage of using the "Picture Mode" to make a movie is that it allows the user to make measurements on each image in the final animated movie without having to first extract these images using a program such as ImageJ.

Once you are finished making your movie, be to rename it. Copy the movie to your M: drive (by logging off this computer locally and logging back on to the network) or post it as a note to the Public Folder for our course.
