"Film-like" Motion in Different Cameras? (1 reply and 4 comments)

Hi Mr. Deakins,

I have been thinking lately about the motion that a camera creates. 24FPS film set the standard and digital cameras have been trying to mimic it all along. It seems that the Alexa mimics this motion perhaps the best. Do you notice a big difference in the motion that various cameras produce? Do you owe this mostly to the sensor technology or to lighting/color/lens choice? On a related note, have you ever shot on anything digital other than an Alexa and what was your experience like?

I'm wondering if achieving a "film-like" motion will allow people to suspend their disbelief more easily. This is why I ask.

Thanks so much.

Joseph

Once you get into the realm of 24 fps with a 1/48th shutter speed, with that traditional look to the motion, I don't think the differences between the digital cameras on the market are enough to create problems "suspending their disbelief" in the average viewer.  Sure, there are some differences due to things like global shutters versus rolling shutters, and the readout speed of the rolling shutter, mainly visible on fast motion, and other things like edge contrast can affect the "crispness" of the motion besides the shutter time, but none of these artifacts tend to be strong enough to throw a viewer out of movie.

Maybe some of the cheaper cameras with a problem with "jello" motion from their rolling shutter in fast movement would be distracting.

Is the shutter speed on all films always at 1/48th? Can you shoot a film at a shutter speed of 1/60th?

Sure you can, I do it now and then, 144 degrees, either because I’m dealing with flicker problems from 60 Hz lights or because I want a crisper motion, a more subtle effect compared to a 90 or 45 degree shutter angle. The Russo Brothers shoot a lot of the action in those Avengers movies with short shutter angles. But 1/60th at 24 fps is hard to spot compared to 1/48. I recently had a fast camera move and the director wanted it to look faster so I went from 1/48 to 1/60 to give it a little extra snap.

Thanks for your thoughts David. Do you ever utilize grain overlays in post to simulate film grain?
