Green screen/keyer need to narrow to fit

Hi,

The video of my and the green screen behind me is narrower than the frame, because I recorded with my iPhone vertically. When I key the green screen, the image fills the entire frame, messing up the effect (image below). How can I fix this? Thanks!

Besides what Tom said: even if you key it correctly, you need to trim or mask the image behind it, otherwise it will still fill the frame (hint: it did already fill the frame, without any keyer effect). The easiest may be to select Crop->Trim and drag the left and right edges in.

In your last screenshot, your project is vertical but your new video is not.

You should decide which one you want.


FWIW, I took a screenshot of your last image, added to FCP and just by dragging the Keyer effect got a rather reasonable result; not perfect, but a good start. It did key out most of the green. It did help that this new take has much better lighting.
