balcony explosion
Posted in: Work in Progress (WiP)i just grabbed some footage i shot in order to improve my matchmoving, 3d, camera projection, roto and compositing skills.
a simple sky replacement, some roto, i almost did no grading to the image, i just tried to match the color values.
i´m pretty happy for the first result but i would be glad to get some additional input
it was done in AE and 3d Studio, 3d tracking with Syntheyes.
i had some trouble with camera projection (f.e. with the stones on the floor. Because if i painted in one frame, reprojected it on some simple geometry (basically the wall and the floor) i got some perspective distortion (i guess because of the nodal pan) which i had to fix with some corner pinning. I don´t consider that a good solution, it´s a little messy.
Also sometimes i found it difficult to get a perfect track, because of some minimal jittering that i find really hard to fix. i tried to average some tracks together but i couldn´t eliminate it fully.
some things i would have considered, but could not implement due to time restrictions:
-moving of the bushes (seemed pretty complex, any ideas?)
-reflections in the window: shouldn´t be that hard, but the dust/debris passes so fast i guess i can get away with it.
thnx
