1/60 shutter speed the sweet spot for 5d? at DVinfo.net

Jay Birch · December 13th, 2008, 07:58 AM

I have been mainly using the HVX200 for shooting and always set it to 180.0d instead of choosing shutter speeds (unless I need a certain look). Is 1/60 a similar look to 180.0d?

The 180 degree setting is an exposure of half the frame duration. On the 5D MkII (30fps) that would be 1/60th. If it shot 24fps (we wish!), it would be a shutter of 1/48th at that frame rate.

For a slight over crank, use 1/60th, slow the playback to 24fps, and you'll maintain that 180 degree look.

For an under crank, set the shutter to 1/30th (360 degrees), then drop every other frame. Now you have 15fps at 180 degrees. Speed up to 48 fps and the 180 degree look is maintained - with fast motion, of course.

Not exactly RED frame rates and ramps, but we have to make due!

thanks mate, i thought that would be the case.

This is all academic though unless you have a camera that lets you choose the shutter speed yourself...

Sad but true! (I'm hoping I can learn to trick the thing...)

Is it possible to set it to 1/48th?

"Is it possible to set it to 1/48th?"

Not at the minute, it jumps from 1/40 to 1/50.

Merci. As a consequence, Canon is limited. A better 25 frames conversion for 180 degree motion than converted it to 24 frames.
