You could film your subject in front of a greenscreen, then key out the green leaving the subject. Composite that layer on top of a background. The tween the transparency grading filter over time from opaque to transparent.

If you can't film the subject with greenscreen, then use the garbage mattes to cut it out of the footage, then apply the same transparency effect.

Or if you want to go really 'back to basics', simply film a shot with your actor in the scene, then continue filming with him NOT in the scene, then cut between the two. It'll look like the actor 'disappears'. Oldest trick in the book.

Yes you can cut / fade / wipe / dissolve between the two shots and as long as the empty background exactly matches your background plus subject shot then only the subject will appear to be affected.

Beware of foliage moving in the background if filming outside as this will reveal the transition - it is eesentail that the background in both shots is identical.

Someone posted some wipe test footage on here in the last week or so which showed how you could acheive the effect.
