hands, i.e. where the actual items will be in 2 dimensional space in
front of you as you film? especially as it applies to specific moving
items on a graph as shown in the video? You can't just fudge the data
points to fit your hand movements later as that defeats the whole
point of showing real data.
You can scale the graph of course, but then you have to ensure your
hand movements are accurately scaled in an X and Y direction.
Of course you could just guess and practice, and kind of "calibrate"
your hand gestures based on distant points in front of you or
something, but I'm guessing that would take a lot of practice and
re-takes to get it right?
I also guess you could project the live data onto a huge screen in
front of you (behind the camera) and you'd have a real time reference
point system to work from, and then scale the data in editing to fit?
Maybe it's a lot simpler than I imagine, but I can't help but think
it's not going to be as easy as it looks?
