[Tobias Heilmann-Schuricht] “On V2 I have the image I would like to place inside the TV set image area (PIP)”
Layering the two images is a more-or-less trivial exercise, but doing it convincingly is of course the challenge. You might be most puzzled by the challenge of matching the movement of the background plate (TV set) — which can be roughly accomplished by using the stabilization function on it, then applying (copy-and-paste) that data into the foreground element (picture you wish to insert). This isn’t really what the stabilization mode is intended to do, and there are a lot of factors that will come into play that will most likely not make this the preferred method to match the motion.
There are a number of compositing applications that are ideally suited for delivering a composite like this… Motion, AfterEffects, MochaPro, Nuke, Smoke, Shake, etc., etc. What makes the effect realistic is usually tied to trying to match the original environment of the shoot — simply pasting in the replacement video unaffected doesn’t really satisfy most audiences — you do need to mix in some optics like aberrations, reflections, and overall chromatic balance.
