I don't know what you mean by a "Picture By Picture". Do you mean Frame by Frame - that is one frame AFTER the other? Dunno .. .
Anyways, I would obtain, or create thru something like Particle Illusion, an explosion and preserve the background transparency - the ALPHA channel - and then bring THAT into Vegas
Once here it would be
TRACK1 : Explosion
TRACK2: Corridor/doorway . .whatever.
Problem here is that you NEED yourself infont of the explosion .. well, I think, you gotta have a sandwich of tracks
TRACK1 : YOU!
TRACK2 : Explosion
TRACK3: Residual BackGround
TOUGH!! This is real tough.
Now you are
really going to appreciate the craft that goes into GREEN or BLUE screen masking and Chroma Keying. If you COULD get a a short sequence of you running AWAY from a well lit blue or green screen and CK out the BG you could very well place this on TRACK1. However, if you have the patience you CAN pull off quite a bit by using MASKING. It wont be the perfection you can achieve with well done CK-ing.

This is the easy bit.

Insert a velocity envelope and adjust where you want.
