A ball head is not the best choice for video work. What I would recommend that would be compatible with the 488RC2 (using the same quick release system, that is) is Manfrotto's 128RC fluid head.
The 128RC only has two axes of movement and, because of that, I use Manfrotto's 438 levelling head under my fluid head to be able to easily level the 128RC head without messing with the tripod's legs.
In reality, I use the older 3130 fluid head and 3502 levelling head but these are just old numbers for the same items as I listed above.
