Slit Scan looks fine in Motion preview but not when I Export to Movie

As I look more closely at it, it looks like the glow that is part of the slit scan filer has just disappeared once it is saved to a mov file. The glow setting is 0.14, which looks perfect in the preview, but it's just gone in the Quicktime file. So strange.

Thanks for your reply, Ben.

The render settings are:

Resolution: Dynamic and Full

Quality: Best

Lighting on

Shadows on

Reflections on

Frame Blending on

In the export settings, I typically just leave everything as current settings, and use canvas settings, but I've tried changing everything and nothing makes any difference. I posted it to YouTube if you'd like to see what the problem is. The link is:

You can see at about the 3 second mark that the Castle logo with drop shadow is on a black background. The background isn't ever supposed to be black, and isn't in the canvas window. It's supposed to vary from light gray, to yellow and white, but never black. There is also supposed to be a white horizontal glow that spans the width of the frame right about the center, and that has just dropped out completely. The top also drops to black and shouldn't. Any help you can give is greatly appreciated.

Thanks for the suggestion GFXZen, but no luck. I did find sort a a duct-tape type fix though. I tried the filter Slit Tunnel to see if it had the same issue, and surprisingly, it didn't - it rendered perfectly. But it didn't provide quite the same effect I was looking for, so I duplicated the background image that I wanted to use the Slit Scan on and dropped it to the bottom of the layer stack, and left the Slit Scan filter on the image above it, and it looks great. When the Slit Scan areas drop out in the final movie, you see the Slit Tunnel filter there instead, and it's not even noticeable that they are different. I guess it's just a bug. Thanks anyway for your help guys!
