When in ACES space, Resolve grays out magic motion/blend tool for HDRx clips shot on RED.

Would it be advised to apply the second source and use a luminescence qualifier to balance and export the one clip, or would exporting two clips with the different shutter speeds for VFX be a better option?

It would seem Resolve has a few bugs in terms of the latest updates. I have recently been getting grayed out menus, alas I have also experienced Magic Motion available now on the metadata page.

That said, i would still be interested in knowing if both shutter speeds clips are usually provided to VFX or if one plate combined is preferred?
