Screen shot of after effects

This is a screen shot on the effect 'walking through wall' i was working on. Before i shot the main scene i practiced it using after effects. I did this by filming someone walking into a wall, then the actor removing themselves from the shot to then film the empty wall. I then put this footage into after effects and cut the part where he is about to walk into a wall and then the empty wall. This then shows someone walking to a wall and disappearing. To make it more realistic, i put a mask around the beginning of the character and move the mask a tiny bit each frame to show him slowly almost sliding into the wall. To make it even more believable i keyframed his opacity so each frame where hes getting closer to the wall i dropped his opacity by about 20 percent so he's disappearing into the wall. Personally I prefer this effect to the final scene because it looks alot more believable because of the natrual light used from outside and the angle is alot easier to work on rather than side on.
