Motion Vector AOV vs. Custom Motion Vector with Motion Vector shader?

I want to render out a 30 second animation with motion blur but find it too expensive to use true 3D motion blur with Arnold. The alternative is using Arnold's motion vector AOV.


So my question is, what is the difference between the Motion Vector AOV that comes built in with Arnold, and the Custom Motion Vector AOV that requires you to make a motion vector shader?


Are there pros and cons for each one?

AOV is slightly easier, you just add it to the list of AOVs in the Render Settings.

If you have some special requirements, then the motion vector shader has more parameters so more control. But you have to apply it to objects, it's not just an AOV that you add.
