splitscreen and adjustment layers

[pb_4079]

So I'm editing a podcast with 2 cameras and 1 split screen as a nested sequance and i wanted to ad transition between splitscreen clip and individual camera clips via transform effect, so when split screen appears its not just a simple cut, but second camera sliding from over the screen and first slide a little bit too. And also i wanted to use this effect multiple times throughout the podcast. And i tried to use adjustment layer with key frames for that matter, but when you use transform effect on a layer above clip and change the position, clip that layered below of the clip you adjusting is not seen, there is just black background. 

Im definitely doing something wrong, maybe there is another way to optimize the process

Add the Transform effect to the top layer instead.

Then, save it as a preset so you don't have to keyframe it every time:

• Select the Transform effect in the Effect Controls panel.
• Click the panel context menu (three lines) and choose Save Preset.
• For Type, set this to Anchor To Out Point.
