This week I spent some time shooting clean plate video clips. When shooting, I tried to shoot footage that fit into certain movement criteria. The 3D camera tracker in After Effects often needs some short of movement in order to establish and gain tracking information; if you starve the tracker of movement and depth data, there will be no tracking information for the system to solve. Yet, if the movement is too complex or shaky, the tracker cannot compute the depth and movement information. Therefore, I attempted to shoot footage that fit the following instance criterium:
- handheld pans or tilts
- handheld static shots
- supported slides or dolly shots
- steadicam tracking/moving shots
Next I will plan out more shots and attempt to track my first 3D elements into the live action footage. I have attached some photos of the shoot and the slider I used to achieve the dolly shots.
