Hi,
I've made an effect for FCPX that simulates a classic SLR viewfinder.
You can keyframe the focus and exposure sliders, give the needle some random fluctuation and when you activate the build out checkbox you get a flipping mirror at the end.
I'm still looking for a possibility to link the exposure needle rotation parameter to the average brightness of the underlying video, but I haven't found a way to do that yet.
There is an image unit in motion 5 that is called "Area Average" but it doesn't do what I'd expect based on its name.
So, if anyone has a clue, please let me know.
Regards
Robbert-Jan van der Does
