Final Cut Express 4 editing question

I am using Final Cut Express. I've got the video running 9 different videos simultaniously at the same size. What I want to do is have the middle video gradually increase in size until it takes up the whole screen, as a transition into going back to one video instead of having nine going at once.
Can this be done in the Express version?

Thanks

i'm not too familiar with what the difference is exactly with FCP Express but i use FCP 7.
If you are familiar with keyframes you could use the keyframes and scale in the properties. (if xpress uses keyframes, pretty should they would). if not do you have a 2D Editor in your FX tabs anywhere? if so you can us that.
Hope this helps buddy.

Thanks, Keyframing worked

I also would like to make a video gradually change to Black and White, I can't get key framing to work with a color corrector and taking the saturation to 0. Do you know of another way to do this?

Thanks for the help.

you should be able to change it in color corrector. it should show a keyframe timeline above the 3 color palletes. If not then you can copy the clip, remove the B&W fx from the copied clip, place it above the original clip on the timeline and disolve the the top clip out when you want it to go B&W creating the same effect.
