Green Screening on iMovie 10

We have begun to organise ourselves for our next big budget TCTV production... ( ok, no budget is more like it ... )
One of the things that we need to do is some green screen action, so we decided to have a little trial go today. We had a try last year when we made the opening titles for our Doctor Who presentation for the Manaiakalani Film Festival.
All we had to do last time was to drop one clip on top of the other and a nice handy dandy little menu would pop up with useful things you could do, like green screen. This was on iMovie 9 and since then, I have got a new mac book and am using iMovie 10, but I haven't tried to use green screen yet.
I taped some green sugar paper to my board, cut out a print out of the Millennium Falcon and put it on a piece of rolled up green paper and we had a go. I was flying the Falcon while Dj manned the iPhone doing the recording.
A nice shot of a suitable space background was dropped into iMovie and then we tried to drag the Falcon footage on top of it. A very small list of options came up, but no juicy ones like side by side, or screen in screen, or green screen. Frustrating.

After much muttering and grumbling, I found this really useful video on YouTube.
Thank you Mr Mitch Davis - link to his YouTube channel here.




It basically boils down to placing the background footage on the timeline, with the green screened footage above it.

Once you have done that, then a new option appears on the adjust bar at the top. It is the one on the left. You can then choose this option and a drop down appears where you can choose from the more interesting options for editing, like green screen.

Here is our trial today. It is not very long but I am very happy with the outcome. It is definitely something we can do, I have learned something today and we have had a chat about how ere are going to improve it for the real filming.

Apple, you know I normally love you ( except for the standard apple mouse, but that is a whole other conversation ), but this was not the smoothest upgrade transition of a task that was once so easy. It took some shuffling about to find out how to do this today. hhmm.....
