Importing video as an image layer, then activating the video track on the timeline causes iClone to crash
To reproduce the crash:
1. Right-click & drag a video file into the iClone viewport and choose "Image Layer." 2. Click the dropdown for the ImageLayer track on the timeline, and make the Video subtrack visible. 3. Click on the Video subtrack in the timeline. On my system, this causes iClone to crash.
