Motion Capture - Disadvantages

Disadvantages

  • Specific hardware and special software programs are required to obtain and process the data.
  • The cost of the software, equipment and personnel required can potentially be prohibitive for small productions.
  • The capture system may have specific requirements for the space it is operated in, depending on camera field of view or magnetic distortion.
  • When problems occur, it is easier to reshoot the scene rather than trying to manipulate the data. Only a few systems allow real time viewing of the data to decide if the take needs to be redone.
  • The initial results are limited to what can be performed within the capture volume without extra editing of the data.
  • Movement that does not follow the laws of physics cannot be captured.
  • Traditional animation techniques, such as added emphasis on anticipation and follow through, secondary motion or manipulating the shape of the character, as with squash and stretch animation techniques, must be added later.
  • If the computer model has different proportions from the capture subject, artifacts may occur. For example, if a cartoon character has large, over-sized hands, these may intersect the character's body if the human performer is not careful with their physical motion.
