Stopmotion animation with a webcam in UbuntuStudio

The Stopmotion software for stop motion animation is included in the distribution of UbuntuStudio. The demo here was done with UbuntuStudio 8.04 based on Intrepid.

I used an A4Tech web cam which is v4l2. Stopmotion has a problem with these kind of web cameras so you'll need to follow Aearenda's solution here: . I do hope they've already solved this in Ubuntu Jaunty 9.04.

Create an mplayer video import device in Stopmotion

Start Stopmotion and in the menu find settings->configure stopmotion or ctrl-P.

Click add button.

Resize the dialog box to see the start deamon & stop deamon text boxes.

Click video import tab.

In the start deamon text box enter the following (change the ~/RENDER/stopmotion/ folder with your preference):

~/RENDER/stopmotion/startmplayer $VIDEODEVICE $IMAGEFILE 2 0.25s .tempjpgs &

In the stop deamon text box enter this code:

killall startmplayer && killall mplayer

Download my startmplayer file from:

Extract this startmplayer file in the ~/RENDER/stopmotion/ folder, you can change this folder.

Then follow this demo:

Finished product (a bit crude):
