(How to) mask transition 🎭
Here's how to do a mask transition, which is really just a wipe transition on juice.
We actually found the magic mask/auto mask tool made this far easier to do for complex shapes, but maybe that's just user preferences.
Step 1: Take two shots. One of your shots should have an object or subject that can completely wipe the frame (or zoom in a bit in post), and your second shot can be whatever you want it to be.
Step 2: Duplicate your wiping shot and put it on the top and middle layers and your second shot on the bottom layer.
Step 3: Use the pen tool to make a very rough sketch of your wipe. The goal here is to capture the component that is in front of the wipe, so you only need to follow the general shape. In our case, the line follows the upper body, thigh, calf, and foot shape. This is where other tutorials and personal preferences may differ - if you want to do an accurate and time-consuming pen mask...go for it! Or if your object is extremely simple (a flat pole) then just do the accurate pen tool, and skip step 4.
Step 4: Use the magic mask tool to outline the subject that is wiping the frame. If it captures stuff in front of the wipe then that is okay. What you need to make sure is clean is the back half of the wipe that way it is seamless into the next shot. Shooting at 60fps can help make magic masking easier and then you can add motion blur back onto the layer after.
After Steps 3 and 4, you'll see that the two layers combine to make a clean cut around your subject and everything in front of the wipe without having to precisely pen your object.
Step 5: Move your bottom clip to wherever you want the transition to start.
Easy as pie!
