I’m assuming the viral vector can’t pass the blood-brain barrier.

But it doesn’t take 10+ hours to surgically get a virus across the blood-brain barrier, right?

The video specifies that the drug is infused over 8-10 hours. Probe placement - again, as depicted in the video, because I don’t see a real methods section - should take about 1-2 hours. The video isn’t clear if this is interactive MRI or just a preop scan that is then loaded into a stereotactic navigation system in a regular operating room, but the former would add another hour at least. MRI is not fast.
