If you were wanting to capture something like a house being built, then every 3 to 5 minutes would be a good place to start.ĭepending on how often and for how long I need to capture images, I use one for two different methods. If I produce the video using 25 frames per second, the length will be:Ĥ,430 / 25 = 177.2 seconds long. I removed most of the night images before I processed them into the video, but decided to keep a "moon rise" I grabbed an image every 20 seconds from just before sunrise on the first day and went right through to sunset on the following day. When obtaining images you need to figure out the time between each image, or how many images per hour or day you will need to create a video that looks good and isn't too long or short. To create the video from the images I will cover two different freeware applications on a Windows PC and look at using Linux as an option. A script runs on the Linux computer and every x seconds polls the IP camera, grabs an image, re-sizes it, time and date stamps it and saves it to the computer hard drive. The system and hardware I use for obtaining the images is a Linux computer and a network based IP camera. In this Instructable I will detail the steps I use to make a time lapse video.
