Three questions about Vegas

[Thundamer]

Hello!

I'm an amateur at Sony Vegas, so I have a few questions: 2 small and one bigger.

Big thanks to anyone, who can help me out with helping it.

1. How can I create rectangle which rolls in on the bottom of video and on top of it, there's written a text and maybe some picture added. Usually this effect can be seen on news channels, when somebody is being interviewed. This rectangle comes up and there's written a word written of who's being interviewed. I hope you can imagine.
Like in this one:

On 1:14 mark, there's this rectangle. I want to create something like it but much more simpler. Simply rectangle rolls in from below of video upward.

2. How can I reduce (silent) sound for the same audio track, without separating it? Like in movie trailers. When people talk, background sound reduces, when they stop talking, sound gets louder.

3.How can I add two images (or video footages) running at the same time?

BIG THANKS for any help!

1. Look up "Sony Vegas lower third tutorial" on YouTube.
2. This can only be done if the background sound is recorded on a separate track to the spoken sounds.
3. Look up "Sony Vegas Split screen tutorial" or "Sony Vegas Picture in Picture tutorial" on YouTube
