Mirrorred video gets cut off
I've got a video clip of 1080x1920 (9:16 vertical) in a sequence of 1920x1080 (16:9). I am trying to mirror the video clip to fill the frame, but the mirrored effect is cut off.
I thought it had something to do with the anchor point, but no effect when I moved it around.
Posting some screenshots here to see if anyone knows what I'm doing wrong. Thanks!

No other layer is in play apart from the one video clip I am trying to mirror.
