Insert module renders insanely slow?

Is there something I missed that would make a render of a 2D to equirectangular TV screen insert of a 50 second shot (60fps/~3000 frames) take over 7-8 hours via Adobe AE plugin!? Seems super slow on both a Dual D700 2013 MacPro and Radeon Pro 580 8192MB 2017 iMac. I must have done something incorrect, right?

Thanks in advance for the help!

Are there any other effects or precomps in the shot? What format is your media? What type of clip and resolution is the insert? Any more details to share?

doesn’t sound right… something else is going on…
