helicopter effect from aerial still
by Dan Huber on Oct 14, 2008 at 1:46:27 pm

I've got an aerial still and helicopter SFX with which I can make a credible animation of a fly over. I'm wondering whether anyone can suggest some ways of creating subtle tweaks that might add to the realism of the effect. Maybe a way of simulating the shadow from rotating blades or some vibration that will punch my sequence up a notch - thanks,

without seeing the shot it's a bit difficult to say.. but camera shake works well.. also depending how high the copter is, some paper flying around is good. there is a tutorial on video co pilot that shows a power ball type thing.... however he creates some flying paper. check it out.

simulate the shadow by duplicating the helicopter, downing the levels so it is black, bluring it a little then scaling in -100% in y.. should get you started

sorry I have wittered a bit here. but I hope it helps

Thanks for the input. I'm sorry, I wasn't very detailed in my description of what I have so far. My aerial shot doesn't include the helicopter. It's actually a still of a Power plant taken from an elevation to show the full property. By scaling and rotating the shot and adding SFX, I can give the impression that video is being shot from a helicopter. But, I'm wondering if a little vibration (how little?) and/or simulated shadow from the blades might turn this from a nice effect into something special. The sequence only involves 15 seconds in a 15 minute safety video so I don't want to go crazy but I think with some advice I might be able to punch this sequence up - thanks,

The helicopter effect might be nice if you don't think people easily will spot the fact that perspective isn't changing.

You could also cut a mask around the property, copy it to a solid, and use it to highlight the property in question.

You could get around the perspective issue by using the Photoshop Vaniushing Point technique to import the power station as a 3D set of planes. Not perfect but you can get some small perspactive changes from a still photo that way.

Videocopilot has a video tutorial covering this if I remember right.
