Frame Ranges refer to the different ranges you can create and use under each Pose Group in Retargeter. These are based off of the frame length of your current scene. Essentially what these allow you to do is use certain poses only on a specific frame range in your scene.
This is useful when you are animating a long video performance that may go through different emotions, or even a video which cuts to a completely different scene. A pose that fits and works in one range may be completely different and throwing off your results in another section of the shot. You can divide up your ranges into the talking and non talking ranges, the yelling vs normal talking, or the changes in emotions. When using frame ranges, you can select which poses you want to affect each range.
For example, if you retarget and are noticing that the smile you created is needed for the first 200 frames but is not needed after that point, then you can separate out the frames and choose to use the smile only in certain sections.
Adding a Frame Range
There are two easy ways to create a new frame range. With your Pose Group selected, choose one of the following options:
When selected this will bring up a new window where you can input the name and the frames you want this range to represent. You cannot have overlapping frame ranges, so you may need to edit your existing ranges before creating a new one.
Editing and Deleting Frame Ranges
You can edit the values on a frame range by double-clicking the value in the window, or by selecting 'Edit...' or 'Edit Range...' in their respective menus.
Frame ranges can be deleted by selecting the range in the window and choosing 'Delete...'.
*Note - Deleting a range is not undoable, do not delete a range unless you are sure you don't need it. Making a Backup can be a good idea when you wish to remove a range.
