Huh, have not seen my response to this, posted some time ago, I will
give it to you again, shorter.
You can do this by shooting the master in wide screen high-def,
editing/compositing at 2k rez for the blow-ups, then outputting in SD
rez, like the REM music video ( "Sugar cane") where it's all one
master high-def shot by a pool, zoomed-in and out and panned digitally
in post.
But the easier, cleaner way is, do it "backwards": shoot each guy full
frame head to toe separately on green screen, all playing to the same
pre-recorded track so the timing stays the same. Shoot a "plate" of the
stage, then it's easy to shrink the individual performer tracks down to
fit 4-5 guys on the stage... but you retain each on his own video
layer. Thus they can even move in front of and behind each other a
little, and you can bring them up front as and when you like. Quality
looks better, if anything, when you shrink stuff down instad of blowing
it up. The "blow-ups" here look clean because they are not really
blow-ups at all but full-frame shots. This effect is well within the
cpabilities of VEGAS, it's just 4 tracks of chromakeys over a fixed
background with DVE moves applied to each track. You don't even need a
compositor for this.
