black margin in motion tracking!
I went filming the other day, and brought my footage into after effects to motion track. I was watching a few tutorials on motion tracking by Andrew Kramer, but I couldn’t figure out why I was left with a black margin on one side of my footage after trying to stabilize it. How do I go about fixing this problem? Do I simply scale the footage up some? If anyone could help me out I appreciate it.

The simplest solution and also the cleanest.

try applying a mask to crop out the black edges (note, it may be easier to do this prior to stablilizing the motion, but you can try it now any way). then try motion tile to expand the edges of the video to make the edges of the video less noticeable. set the output height and width so the video fills the screen and set mirror edges on.
you’ll still be able to notice the edges, but in many cases it does a very good job of hiding them.

Something to consider is a video up-reser plug-in like Digital Anarchy’s Resizer or RedGiant’s Instant HD. These plug-ins which use algoryhtms to scale up your video would allow you to scale up with less loss. Nothing that I’ve come across is perfect, but these certainly help.

i have a correction to my suggestion… you won’t be able to use a mask, you will need to precomp the footage and then change the comp size (of the precomp) to be small enough to crop out the black edge of the footage. when you precomp choose to leave all attributes in the main comp…
there is an advantage to this method, it should work equally as well after you have applied the stabilization.

Use the function Motion Tile. search it on google for tuts. it mirrors the edges so it fills the black edges
