Creating time lapse videos

[Rabidable]

If all you have is a webcam, best bet is to try out a program called Flix.

If you have a digital camera, you could take a picture every 12 hours as long as you are on tripod to keep the camera is the same spot.

Or you could hook up a camera to your computer using a 3rd party program, like Sabsik's cam2com.

(only certain cameras work with that program).

Newer Canon cameras can do timelapses with the help of a program called DSLR remote pro.

Regardless how you get your series of pictures, you'll need to turn them into a video.
One way is to use Adobe Premiere, but we don't all have that.  Its possible microsoft's movie make could handle it.
But Photolapse is free.

Then I usually convert the AVI video into a much smaller mpeg with an Avi to mpeg converter.

Another option if you use linux is gPhoto.

I've had some issues with getting this program to select the appropriate camera consistently, but that may be due to my usb hub and my camera.

Yawcam is the program, and it can also be used to create a series of images used for time lapse videos.
Its Free, and it works.
