Re: [Avid-L2] "Camera Shake" effects for airplane in turbulence? Also green-screen of flying through storm?

 

One of the issues of adding post shake is that you have to enlarge the image to allow for image movement and rotation.  So depending on how violent you want the shake to be you may be doing a lot of enlarging.  So if it's possible to shoot 4k for a 2k of HD final I would suggest doing that and farming really wide.


The other thing is that what usually gives away a post process shake is the lack of depth movement cues.  So as the camera is moving in a real world situation it is not just moving up and down but also forward an backwards and all of those have subtle cues in the parallax of objects in relation to one another.  The more shake you add the more noticeable it is that it's fake.

Also, there is the other than camera movement that indicates something is wrong.  Will the performers be expected to throw themselves around the set like the original series Star Trek?

L'ers - I'm involved in a documentary now in preproduction about Pan American Airways, which includes a dramatic re-enactment of an airliner crashing in bad weather in 1928.  For this scene we'll build a life-size replica of a portion of the plane (the cockpit plus the front of the passenger compartment).   We're now weighing the pros & cons of physical effects versus postproduction special effects, and I'd like to pose 2 related questions to the Hive Mind:


1)  Has anybody here done "camera shake" effects in post, to simulate air turbulence as seen inside an airplane during a storm?  If not for an airplane in turbulence, possibly for a building in an earthquake or something similar?   One alternative to this, as currently advocated by our excellent set designer, is to physically shake the entire set during shooting, but that poses challenges of its own.


2)  Has anybody here done a green-screen composite of "flying through a storm" including clouds, fog, and rain seen through a windshield?  If not for an airplane, for a car or other vehicle?  Here too we have the alternative of physically creating rain and fog on set, but that also has complications.


Any successes, failures, encouragements or warnings would be greatly appreciated!
