Image Brightness to Generate Markers
on Jun 3, 2013 at 7:19:05 am

I filmed about an hour's worth of footage where camera is pointing toward a storm. Mostly dark, but occasionally there's a flash of lighting. Is there an expression or script that will have AE generate markers if the brightness is above a certain threshold?

Thanks!

You might want to check this out:

I'm not sure what kind of algorithm Lloyd uses to detect scene changes, but your lightning strikes might trigger it. I believe you can have it set markers.

If that's not quite what you need, I suspect it would be fairly straightforward to set up a script that does exactly what you want.

this looks like it may do more than that, which is great. I want to extract the strikes without playing the whole hour. I'll try this. Thanks!
