24 fps panning with film?

[firehawk]

We all are aware of the rules for panning and motion when shooting in 24P with digital video cameras, but I have seen a number of shows shot on film that pan faster and even much faster without seeing the jerky jitter. How were able to do that?

I'm not sure, but it may be because film's shutter is a little like the Tessive Filter, although not as strong. It appears that Red bought the "rights" to the method and implemented it in their Motion Mount.

On that page is a lot of technical mumbo jumbo, with links to more pages and more mumbo jumbo. But what it is, is that with the Tessive Filter (and to a degree with the old-fashioned rotating film shutter) is that there is blur, just like with video, but toward the edges of the blur, the opacity of the blur tapers down into invisibility gradually, instead of having a hard edge.

Pretty much right on the money here.

Once you get to a certain point with the speed of your pan, there's enough of a blur that it doesn't matter anymore.

Or, you can follow an object -- like a person on a bike, maybe -- and keep that object "stationary," and attention will be on it and not the stuttery background.

In the olden days one would consult a ASC Cinematography Manual table that lists 'panning' speeds and frame rates.

Here's one example.

Since most DSLR shooters, and perhaps some who have graduated to higher end cameras have never seen 'film' based shooting tables for a variety of conditions, perhaps they were under the impression that it was 'anything goes'.

Now, that said, I have seen 'film' strobing effects in the days when only Film film was used for capture and projection... so, not everyone followed the tables, or in order to get a shot, ignored the guidelines.

But the tables were the 'recommended' speeds for panning or moving objects in the frame.
