The Graphic symbol (Red Car), runs along Adobe Animate's main timeline. The MovieClip symbol (Blue Car), runs on its own individual timeline. This causes the MovieClip symbol's animation to only be visible when scrubbing its specific timeline or upon clicking "Control>Test." MovieClip symbols can also be given Instance Names, which allow them to be controlled by code. Graphic symbols lack this feature, but can be controlled by "Loops" instead.
