Shooting 1 Frame At A Time

Published : 11th August 2003


I have a Music video approaching quickly (Friday) in which the Director wants to expose one frame at a time (like stop motion).

We plan on shooting with an Arri SR3.

We need a way to single trigger the camera while still being able to be handheld and move around. I guess I can try to rig an intervalometer, and set it on a single frame, but was wondering if there was another option.

Thanks in Advance

Get a camera that does single frame like an Aaton or Bolex. The SR's have to be modified ones. The phase button is not a single frame substitute.

That is what I thought

Thank you

You can rig a Norris intervalometer and get a reliable(exposure time wise) single frame exposure out of it just by pushing the red button on the controller. It may not be the best hand held beast but certainly better than my reflex Mitchell 16.

I believe the inching knob on an SR-2 runs at 1 fps. Is there something similar on the SR-3?

Art, they both have it but it's not meant for single frame. The Arri's have to be modified for single frame and intervalometer work.

I do this a lot on music videos, especially in between set-ups where the DP is walking around the set telling the gaffer where to hang lights or when the grips are laying tracks or building a crane etc. great for a laugh at the rushes transfer. The inching button on the SR3 runs the motor at approx. 1.2 FPS so that's about 4 ½ stops from your base at 24 FPS. a bit of gaffer tape will hold the button down fairly well.

Good luck with the shoot.

Haven't we gone over this in the past? Using the inching button as an intervalometer is not a good idea. Yes you can do it, however the exposure is not guaranteed to be consistent, and the motor draws a lot more amperage when inching, and continual use of this, causes damage.

Us a REAL intervalometer, rent one, many available for the Aaton and SR. There is also apparently a way to make the SR3 Pop open the shutter, for a one second duration, and then close. Which doesn't harm the camera.
