You can do compound miter cuts in the corners, but sometimes a coped joint is faster and better.
Here's a short video showing you the steps for making coped crown molding joints.
The big trick to getting a tight great looking fit is in the angle you cut the wood at with your coping saw.
Watch the video and discover this common sense trick.

This person is doing it wrong,you should have the saw cutting parallel into the detail, not perpendicular to it! It will fit better!
It’s called back cutting the cope!
And the saw teeth should point towards the material!
Or just use a cope master. One of the coolest saws ever.

Coping paint grade material is a complete waste of time and so is using Pine. MDF or ultra light pains so much better it is also so much straighter and more consistent in its milling it also is recycled material so its better for the environment
I would respectfully disagree with coping being a waste of time. It’s a great skill to have and stick and cope is actually faster than mitering if you get good. Easier to accurate, the joint stays together better, it always works even when the corner is off and is fillable if need be without being seen. But I would agree with the MDF part.
