hi all
one of the shots in a scene in my recently shot feature film.....has a mild shake....meaning ...
a repetitive up and down movement of the image on the film.....i feel there might have been
a problem in the camera at the time of exposing that scene.....what could it be??
is it pin register problem or what??? anyone ..please explain in detail.

camera - Arri 3, shot at 24 fps, normal shutter, day scene.
format - anamorphic , lens-cineovision 24 mm

thanks
cheers!

That sounds like either a problem of the camera or of the post production (telecine or print).

On a side note, I have heard of but never seen these anamorphic Cineovision lenses. As far as I gather they are Japanese. Would you have any more details, like focal lenghts, weight and stop, as well as how they compare to other anamorphic lenses?

Hi,

You need to do a double exposure steady test with the camera. Remenber the Arri III has only 1 registration pin and won't be as steady as a camera with dual pins.

Thanks, I'd forgotten about that page. I'm curious what kind of glass is in there, maybe Canon?

The recent British film 'The Great Ecxtasy of Robert Carmichael' was shot on them.

This can be fixed pretty easily just so you know. We have had to do this in the past at my company, but we rent cameras and use various telecine places, so for us it was not worth looking into 'how it happened', but if this is your cam, you might have a problem

Hi,

A stabilised image will be noticeably softer. Far better to have a steady camera + scanner.

Hi... Yes, we used the Cineovision lenses on Carmichael. We used them for their cold and stark yet slightly soft look - what one might call a "70s look". The main problem with the lenses is that you get some slight vinguetting, with a loss of focus around the edges under certain lighting conditions.
