Motion Study involves closely observing and analyzing the movement of an object or character to reproduce them virtually. To accomplish this task, there are several departments involved including 3D Animation, Visual Effects (VFX) and Optical Systems Capture (OSC).
Through careful observation and analysis of motion, animators can recreate all sorts of movements accurately, ranging from human motions such as walking and running, to animal motions like flying and swimming. VFX artists then use their expertise to make the visuals appear natural on-screen, while OSCs capture specific elements that may be required to enhance the realism of the scene. This includes facial expressions and body positions, which can be captured through markers placed on the subject’s skin.
A good motion study allows for more creative freedom when creating virtual environments, as producers no longer have to rely solely on live-action footage. It also saves time by streamlining the animation process since animators no longer need to create each movement from scratch manually. Additionally, having accurate visual representations allows producers to troubleshoot any issues before actually producing the final product, saving both time and money.
For best results with Motion Study in virtual productions, it is important to ensure that everyone involved has a clear understanding of what is being achieved. Animators should collaborate with VFX artists and OSCs to discuss objectives and review data before starting work. Additionally, maintaining high-quality rigs and markers used for capturing physical data helps ensure accuracy in the final output. Lastly, investing in advanced technologies such as motion tracking software and performance capture systems can further improve the quality of your Motion Study.
