For the first effect on the B&E show...all they did was have two clips on top of each other and then change the opacity to about half (50% or whatever looks best for your footage) on the top clip.the opacity can be found after double clicking the clip which settings you wanna change and its under the motion tab.
You can also use the comp settings and play around with different styles like also mentioned above. for those, have the clips layered one above the other in the timeline and then right click on the top layer, and go to >composition settings and try out each of the settings to see how each will look and affect the clip.
For the moving text, all that is is just a basic text out of FCP7. Create the text and find the clip you want to have the title track across (usually is easier to do with super steady footage panning at a constant speed). Then place the text in the timeline and double click on that section to bring it into the viewer. Go to the motion settings tab at the top and you will need to use the "center" values. Put the playhead at the start of the clip and adjust the text so that it fits where you want it to start. Then create a keyframe for the center position of the text. (this is the little diamond looking icon right next to the values and will turn green when clicked) this tells the footage that this is the start point for the text. Then drag the playhead to the end of the clip you want the text on and move the text so that the same spots line up with how you had it at the start. go back to the motion tab and create another keyframe for the new position of the text. now when you start the clip over and play it back real time, the text should track across the screen with the footage. You can also add keyframes in between the start and end points if there are parts of the footage that are for some reason a little faster than the others while panning. You can keyframe almost every aspect of the settings so play around with those as well. **one thing that i do whenever im gonna do this type of keyframing under the final viewer (one on the right) at the top there is a drop down arrow next to the size. i click on >image and wireframe so that i can just click and drag the footage as the playhead moves. this creates an automatic keyframe when turned on and its a lot faster imo.
that is the quick and dirty way of keyframing tho. if you have motion or after effects, you could always export that clip to one of those programs, put in the text and use the tracker to automatically give you every point. both methods have their pro's and cons if you check out my vids i use both methods for different things.
if this doesn't make sense you can pm me and ill try and explain better with screen shots. hope this helps!
