How-to use Toonloop 2
This document explains how to install and use Toonloop 1.x and 2.x for Ubuntu GNU/Linux.
A user has written a French version of this how-to. You can find it here: en français sur artdoeuvre.org. For a Chinese version, friends from OpenLab Taipei have translated it and you can find it here: 中文.
Warning: Some features of Toonloop have been deprecated in the 2.x version. They should be no longer listed here.
Toonloop Full is supported by either Ubuntu or Debian GNU/Linux operating system. You should get one up and running prior to do the next steps. See the Ubuntu installation documentation to learn how to install Ubuntu on your computer.
Step 1 : Download
There are two packages you need to install. First install Pygame 1.9, next install Toonloop. See the Download page to get the latest release.
Step 2 : Installation
Once you have successfully downloaded the packages, simply double-click the files and the GDebi package installer should ask you if you want to install it. Make sure you install Pygame before Toonloop.
Step 3 : Launching Toonloop
Once the software is installed, there should be a Toonloop icon in the Applications : Sound & Video menu. Choose that application from that menu. It will launch Toonloop.

Toonloop uses the first video camera it finds. Toonloop currently only supports cameras whose driver supports the Video4Linux2 API. To use Toonloop, there should a file called "/dev/video0" on your computer. If you see an image from a video camera input in the Toonloop window, it means it worked. Otherwise, Toonloop should display an error message. If it is the case, you should start Toonloop from the terminal in order to be able to read some more informations about the reasons it crashed. See the section "Starting Toonloop from the Terminal" in the Advanced How-to for more informations about this.
Once Toonloop is running, you should see a black window with the live video input image on the left. Congratulations ! In the left window, you can see what is seen by the live camera. In the right window, it is the result of the stop motion loop.

Step 4 : Make sure you are using the right camera
If you have more than one video camera and want to use a different one than the one Toonloop has chosen, you need to specify Toonloop options at startup. See the "Custom Options" section.
Toonloop supports only Video4Linux2 video cameras. That includes USB Video Class cameras, as well as some analog video capture cards. Here is a list of supported cameras. They have all been tested with Toonloop 1.x and 2.x:
- Logitech C500: cheap, works OK.
- Logitech Quickcam 9000 Pro: expensive, but provides more pixels and a pretty good image quality.
- Pinnacle Dazzle: This is a cheap analog video capture USB device. With a good camera, can give a very good image quality with manual controls, though interlaced.
- Osprey 110: Good PCI analog video capture card
If you are using an analog video capture card, and not a USB Web cam, you might be interested in selecting a different video input. You can use the v4l2-ctl command-line utility that comes with the ivtv-utils package for that task.
See the Data Sheet.

There are many ways you can setup your video camera to create nice looking animations. The general idea is to have a stand, and at least two light sources. A background light source, such as a light box, can be interesting as well to create transparency effects. A good general purpose stand to recommend is the Manfrotto Magic Arm. This model can be snapped on a table, and can be moved freely to suit the setup you need. It can make your camera look down. You might also consider using cables ties ("tie wraps") to keep you camera on the stand, if it does not have a 1/4 inch screw hole.
