* Specific hardware and special software programs are required to obtain and process the data.
* The cost of the software, equipment and personnel required can be prohibitive for small productions.
* The capture system may have specific requirements for the space in which it is operated, depending on camera field of view or magnetic distortion.
* When problems occur, it is easier to shoot the scene again 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, oversized hands, these may intersect the character's body if the human performer is not careful with their physical motion.
