- Enter the actor.
- Strike a T-pose.
- Action
“No actor at the start of the video” rule
Remember to always record a few seconds without actor in view of cameras in the beginning of each video. This is very important. The software will need to see a couple of seconds of background of your scene (no actor) when processing the video.
T-pose
It is preferable to have actor strike a “T-pose” before the actual action. The software will need T-pose for building actor appearance model during tracking.
Takes
Take is a concept originating from cinematography. In a nutshell, take is a single continuous recorded performance.
Usually it is a good idea to record multiple takes of the same motion, because a lot of things can go wrong for purely artistic reasons.
Iterations
A common problem with motion capture is “clipping” in resulting 3D character animation. For example, arms entering the body of animated computer-generated character. Many CG characters have various items and attachments like a bullet-proof vest, a fantasy armor or a helmet. It can be easy for an actor to forget about the shape of the CG model.
For this reason, you may need to schedule more than one motion capture session for the same motions. Recommended approach is:
- Record the videos
- Process the videos in iPiStudio
- Import your target character into iPiStudio and review the resulting animation
- Give feedback to the actor
- Schedule another motion capture session if needed
