iStopMotion is a registered trademark of Boinx
software, and I am in no way affiliated with Boinx software. In this lesson, I’m going
to be teaching about onion skinning in iStopMotion. We already know that the overlay slider here
lets you fade in and out what’s going on in the previous frame and it gives you kind of
a ghost image. If you come down here to the bottom right and click on the view tab, it
should say onion skinning. If you want to click the arrow beside that to bring down
the options. If you click this check box right here, that’s going to turn on onion skinning.
What that does is its similar to the overlay, but it’s going to allow you to see more than
just the previous frame. The slider right here, you can slide it anywhere from at its
minimum you can see the last 2 frames all the way to the maximum, which is going to
let you see the last 6 frames. You’ve also got the display option here. By default, it’s
set to blend. You can set it also to minimum or maximum. It’s just going to change how
the ghost looks. In most cases, I prefer to use minimum, but you use whichever of the
settings you like. As you can see, you can see the ghost image of the last 6 frames.
This is extremely helpful for letting you compare and contrast the last couple of frames
so that you can get your animation to look exactly how you want it to. That’s how you
turn on and use onion skinning.
