I `m looking for help with the folowing problem. We are shooting a 35mm movie and have done some VFX shoots. We shoot a scene with a streetcar , where an actor is hanging outside. Regarding the budget the VFX supervisior where asking for not panning the camera. we have done 3 different sizes and angels with two cameras at the same time. All the shoots get a reasonible motion blur / shuttering. I thing it s a " simple " shutter effect because the streetcar went`s in less then 3 1/2 seconds through the frame. The other thing is that the " actor" looks like a " double Image". on every frame.( it was a night exterior shoot with lit greenscreen in the windows behind the actor) ?.
We have to re shoot the sequence , and i have propose to extend the time how long the streetcar is in frame. Did any one have any charts of how long the object must be in frame that it is " shutter free". I get charts for " recommended panning speeds" but no information for fix camera position. Or did some one knows a formula so that i can calculate proper speeds for different lenses and distances !?. Would a change to a 90 dgree shutter angle minimate or solve the problem !?.
Thanks a lot for any answer in advance , and please excuse my poor english.
