shaking title/freeze frame effect

The Projector is responsible for the shaking title effect. With "generate keyframes while tweaking" option selected, I created the shaking effect manually by moving the X/Y coordinates of the projector randomly in the compositor. I added further jerkiness by resetting projector coordinates manually via the X, Y, Z projector coordinate tool. I set the coordinates to 0,0 sometimes and then wildly negative and positive numbers (-264/+300) for real bouncy titles. I enabled the video track with titles only:
blurTitleShake
400K

After the shaking title experiment, I then completed the picture by adding a second video track with a Freeze Frame.
blurTitleShakeVideo
3MB

Timing fade outs and the proper freeze frame position were somewhat of a chore, but since I will be repeating this same sequence with different video and titling three or four more times, I should have the process optimized after finishing the last one.
