UFO in rendered movie
on Apr 27, 2011 at 1:56:45 pm

Hi all,

I have an unidentified foreign object in my rendered movie.

I've got 50 duplicated layers to extrude an object into 3D, and I think the object - a straight line made up of little blocks - could be the corner handles of the footage layers - there's absolutely nothing else in the comp it could be.

The object is only very faintly visible for part of the animation inside AE, but there as a solid line right the way through in the rendered movie.

Does anyone know why AE might be putting it there or how I can get rid of it?

Thanks in advance!

D

Michael's right about the screen shot, but here's a shot in the dark:

You may be seeing the edges of your layer; it happened to me just the other day when removing the white background from a logo to create transparency . A simple rectangular mask can crop out the edges.

I'm with Dave - a small artifact, a lost pixel from a line in your artwork can create that. Mask around it and that should solve the issue.

Ok, here's the screen shots. As you can see, in the first one from AE, there's a very faint line in the bottom right corner of the screen, outside the main image.



When rendered, the line is much more pronounced. The line follows the same point on the outer rim of the image which is rotating around the static central image.



I've tried masking around the original image and the issue persists and I'm convinced it's coming from the duplicated 50 layers comp - is there a way to mask around all those layers?

In the nested comp, copy the mask from one layer, and paste it onto the other layers.
