<p>I am working on a Premiere project that will be exported for YouTube. At the end, there is a screen with two boxes in which I've placed clips of my previous videos. These will be annotations on YouTube. The background of this end screen is a timelapse video that I took of a white board drawing being created. So, in order to 'cut out' the boxes where the annotation video clips will play, I used garbage masks. Everything looks great in Premiere. But when I render it, the background white board video disappears. It's just the two smaller annotation video clips on a black background. What am I doing wrong?</p>

<p>TLDR: The clip on which I've placed my garbage mask is rendering black when I export it.</p>

So are you applying the garbage matte to the whiteboard clip or the annotation clips?

@stib I used the 16-point garbage mask and put it over the square where the annotation clip will play. Then I added the Alpha Adjust effect and selected Invert Alpha. This is my first time using a mask in Premiere, so maybe I'm just doing everything backwards. But it plays the way I want it to look in Premiere. It's just when I export it that it looks weird.

Try adding the mask to the annotation layers, you shouldn't have to use the invert alpha effect. And you won't need any masks or alpha effects on your background.

TLDR: The clip on which I've placed my garbage mask is rendering black when I export it.
