In this tutorial I quickly show how you can make timelapse movies.
1.
First you need nice webcam where you can download pictures.
Here is couple of Google searches that I use when I'm looking for cameras.
go to sleep, after a (about)thousand pictures you are ready to make your movie, it is simple.
just cd into your imagefolder and use mencoder to make your movie.
I wrote a simple bash script to grab the images and save them with the time and date:
Code:
#!/bin/bash
if [ \! -d $HOME/logs/webcams/soton/ ]; then
mkdir $HOME/logs/webcams/soton/
fi
cd $HOME/logs/webcams/soton/
while true; do
DATE=$(date "+%y-%m-%d-%H-%M-%s")
wget --timeout=15 --quiet -nd -np \

mv largesize.jpg soton_high_street_${DATE}.jpg
sleep 900; # be polite and use reasonable time values ;)
done
I'm looking into how to do this with my own USB webcam - I should think it's possible to grab an image from it relatively easily and it'd make an interesting video to see how we move around the flat

I'm glad you find this tut useful, did you manage to make your own movie from your webcam ?

In the end, I didn't.
I found a program called grabby that would take a single image from a webcam and then store it in a particular folder, but I only managed to get it to compile on Slackware after I contacted the author and he provided me with a few patches. Even then, after it successfully compiled, it wouldn't get the images from my webcam, so I gave up.
