Various post-production and distribution tools for volumetric video data are enabled. For instance, a method comprises receiving, by a device comprising a processor, a group of images, determining, by the device, first points of interest of a first image of the group of images and second points of interest of a second image of the group of images, comparing, by the device, the first points of interest to the second points of interest, and determining, by the device, from the first points of interest and the second points of interest and based on a result of the comparing, sets of candidate coordinate positions of a joint of a character represented in the first image and the second image.
