Creating a timelapse in Linux
August 19th, 2011 7:30 amHello,
I’ve written a couple of scripts for making timelapses in Linux. It’s fairly simple stuff;
Create a screenshot every 15th second by running the following script in a terminal;
#!/bin/bash
# Takes a screenshot of my second monitor every 15 seconds
# Only have one monitor? Drop the -crop part ...
mkdir ~/img
while [ 1 ]; do
# Uncomment the line below if you only want timelapse of your second monitor, and both monitors are 1680x1050 big.
# import -window root -crop 1680x1050+1680+0 ~/img/LD21-$(date +%y%m%d-%H%M%S).jpg
import -window root ~/img/LD21-$(date +%y%m%d-%H%M%S).jpg
sleep 15
done
(The script is interrupted by pressing CTRL+C)
Then encoding the images can be done using mencoder, like this;
mencoder mf://*.jpg -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell -oac copy -o output.avi
If you want audio, add ‘-audiofile somefile.mp3′.
Hurray!
Nice, thanks
Or you can use scrot instead of import =)
