screen replacement on aftereffects experiment


After the collage and looking through the battle royal film stills, there was this bit where the girl looks at the blood stained photograph, taken just hours before, of her and the other classmate (and the other who just got killed now) - I thought it would be interesting to try video collaging and I've been wanting to try the motion-tracking/screen replacement thing on aftereffects. Ideally you would have a green screen on whatever you want to mask your footage on, but this was from a film... anyway, I tried it (need to learn basics of aftereffects even navigation) and I made this small loop with my limited skills. It was really fun and exciting, and the motion tracking isn't perfect, and I don't know more ways to make it more realistic (but to be honest does it need to be? I want it to be like a collage), though I did try and match the brightness etc. I am just concerned about copyright etc. and I know if I'm under the university it should be fine showing here, but for future works it could be tricky. I might think about recreating these scenes in some way? though filming is another challenge as I'm also not experienced in filming people/myself. I'm thinking of trying motion tracking to other footage, perhaps my own from the past...
