Sure, will see how I get on. I'll give it a whirl tonight if I get time.
Just a suggestion: record in the highest resolution you can. That would normally be the size of your display. My iMac is 2560 x 1440, for example. Some movie editing apps, like iMovie, export only up to 1980 x 1020, which is a problem if you want to retain the max resolution the video is made at. (There are ways around this, but they are more trouble than they are worth).
Anyway, have fun, and while you are at it do some aerobatics in and around the bridge -- like looping around it, or doing a slow roll while flying under it. You can also do a Cuban-8 where you cross the 8 just under the bridge.
