Time Lapse Process

The time lapse movie is made each night from a collection of the days images.  The camera is set up to capture one image every 30 seconds.  Thirty seconds makes for a pretty smooth time-lapse although it set to 12 seconds during ice-out.

At the end of the day the camera is turned off and a script is run to process the images.  Each image is resized to 640x480 pixels, contrast is adjusted and the image is sharpened.  The webcam program SebecTec controls the creation of the time-lapse using MEncoder

The final step is to automatically write the video file to the server and this is done using an ftp script.
