If you haven’t installed it already, it may be on your installer disk.

1. If by comp view you meant ‘computer’ view, press shift-cmd-3 and OSX will take a snapshot of the screen and it will appear as a file on your desktop called ‘picture1’.
2 & 3. May be the same cause. Go to your System Preferences (under apple menu) then to your expos

Have you tried keylight that came with AE 6.5? It’s one of the best keyers made.

Yeah, I use about 4% noise on mine to kill banding (just on the layer that bands though). Ideally you want a dither plug-in which randomly moves pixes around to diffuse the bands. Don’t know who makes deband for AE though.
BTW Blur will make it worse. Take any picture and crank a gaussian blur way up. You’ll notice as the image heads closer to gray it will band like crazy.

I would stick to what you did originally however, animate the camera using layers of nulls.
So:
Create a path spline, create your profile circle and use a sweep nurbs to create your tube. Duplicate the original spline and offset it so it’s centered up inside your tube.
Create a null and name it something like “dolly” so it gives you the notion that it is just something the camera will sit on. Now add an align to spline tag to the null and keyframe the position parameter over time. So the null should move through the tube.
Now you can simply put a camera in the null group, the camera will have it’s own rotational/position controls independant of it’s jouney through the pipe.
But what I do is add a second null in the first null group and put a vibrate tag on it and set the vibrate settings to make the camera jiggle. Then I group the camera under this vibrate null.The point being is to isolate each layer of movement to it’s own null. So you have the dolly null, the vibrate null, then the camera itself. I even isolate the camera under one more null so that I have a third null that is camera look at or set it to target something, then I still have the camera’s controls left alone to do something with if needed.

Use a composite tag on each item that needs to have it’s own matte (so with this matte it can be isolated from the full render). Go under object buffer in the tag and give it a unique number.

Sticking to the truest sense of the original rotoscope from days of yore, I would say that rotoscoping is ‘any process to match additional art to a pre-shot moving image’. Whether it be cutting a matte, creating lightsabers, or in more modern terms, shooting someone on DV as a motion reference and animating 3D characters to match (cheap mocap). Since roto was originally made so that cartoons could take on the qualities of human movement.
As far as rotoscope versus rotospline. It is my belief that rotoscope is an umbrella word that encompasses everything rotoish despite the technique used. Rotospline to me is a more specific word, albeit an arbitrary one that I think just came from terminology that some applications dubbed it, that is used to be more specific about using spines (masks).
I think if you heard 50 out of 50 post houses say they need to rotoscope a shot, they will use a meriod of tools regardless of the term rotoscope, whether it be painting, using splines or other.

Well, first look through the Cow archives for ‘roto’ there should be a ton of info.
Roto in AE is using the pen tool to draw a shape around your subject. Then turn on keyframing for the mask shape parameter. Now whenever you change the shape over time, AE will interpolate the movement for you. But before diving in, we have written lots of tips in the Cow for roto techniques.

Actually you want the opposite of my first suggestion, so do the second. It will look better anyways.
