AE Motion Track Stabilize
I have footage that is about a 10 second clip for a short film. It is a bit shaky and I would like to stabilize it in AE. I choose track motion then i click stabilze and set up my trackers. I get a clean track. My question when I applied the track data to the original footage the shot seems more stablized and less shaky but its not in full 720×480 frame. The anchor markers shift the shot as a hole around. How does one accomplish stabilization? Thanks

When stabalizing, After Effects can’t “create” the missing pixels. Instead, it moves the whole clip around, so that the point you stabalized stays in one place. One way to fix this is to scale the clip just a little bigger so it fills the frame. Another way is to repeat the edge pixels. I saw this in a tutorial by Andrew Cramer. In version 6.5, the plug is under the ‘stylize’ menu, it’s called ‘motion tile.’ By setting the output width and output height to the amount of pixels you’re missing on the edge, and checking the ‘mirror edges’ checkbox, it’s going to repeat the outermost pixels of the image. Beware though, it doesn’t work in all instances.
Hope that helped,

This behavior is normal and this will happen no matter how you do stabilization. What happens is the computer tracks a point in the clip and finds how much it strays away from it’s original position. The inverse of this data is then applied to the motion of the clip to stabilize it. Essentially, AE tries to track your object and keep it in the middle of the frame. It does this by moving the clip around. Therefore the clip will inevetablely no longer fill your frame perfectly. You can scale the clip up to make it cover the whole screen. Before you do this remember that the edges of your clip will be clipped if you are outputting to TV so you might not have to worry about it. This is kindof a hard topic to explain in words, if you have the Myer’s “Creating Motion Graphics- Volume 2” I recomnend reading the section on stabilization it’s quite helpful.

haha A.N you beat me to it 🙂 I was typing in my response while you posted yours. Nice explanation btw.

As I was typing, I had the feeling someone was trying to say the same thing. So I kept updating the forums in a different window to make sure no one already responded…

Fantastical guys thanks. I will try the scaling the clip. Being that its a shot for a short movie, if I add some letterbox bars on top and bottom it might help doing that alone. Thanks
