Sony Vegas help. picture in picture, chroma key, zoom, scale and crop

[Grinnders]

Ok... I'm just moving over from studio to Vegas Pro 8

I am familiar with chroma keying and picture in picture with Studio but struggling with Vegas.

My objectives is to replicate something I achieved in studio. Overlay a chroma-keyed video against part of a static background, but the chroma-keyed image is simply a zoom in. Imagine a cuddly toy suddenly appearing from a corner of a static background frame, that then appears to get closer to the screen (without taking over it all)

I have tried the interactive tutorial but it keeps suggesting I scroll right on the timeline to something out of view and then increase the zoom on the timeline. I end up scrolling to the end of my piece and zoom to max.. no change.

I realise I have to look at this as five actions.
1. crop (or zoom in) chroma video to lose unecessary surround (crop/pan event) although I would like to change this regardless of aspect ratio.
2. put it picture in picture (make it first video track - done)
3. reduce the percentage of screen size it takes over (??)
4. place it in the appropriate position on screen (ok with placement on text but how with video)
5. chroma-key it. (found this plug-in.. at the mo background disappears but subject goes transparent.)

In studio this was picture in picture with crop (lose edge) and scale (size and location on screen) pan & zoom (ah ha.. maybe it was a static picture) and chroma key (eliminate background).

Would this be easier as a static picture that I panned and zoomed ?

Anyway all help appreciated.

Ok.. I've done some tutorials and fixed most of my problems....

Please treat me as a vegas numpty and ignore this thread.

Sorry for any inconvenience.
