Strobing

Absolutely!
But instead of an elaborated chart you could use a simple rule (idependent of focal length): any object should need a minimum of 8 seconds to pass from one side of the frame to the other. That doesn't sound like much, but give it a try. Those coming from video are in for a surprise how slow that feels…

I agree you need to respect the minimum safe panning speeds, but a lot of the judder in the examples in this thread seem to be quicktime artifacts. I find most footage I look at on a computer screen is juddery like this. Has anyone looked at the same clips in a more realistic viewing environment? Say a proper render out to DVD or bluray?

Anyone know a simple DPX reader to see if the judding that i get on quicktime will not show up in DPX.

Ive tryed the software BLENDER http://www.reduser.net/forum/showthread.php?t=6084
But its not user friendly.

thanks

The biker footage looks like a low shutter angle was used.
I guess any camera has a stroby motion with that.

Handheld samples that McGregor posted looks weird though, if deep DOF is the problem or not, I guess that asks for a test.

And there's that too...
But I guess people using RED already know that?

I'm not sure. After all, the price makes RED accesible to many who've been shooting only video before…

And, of course, deep DOF is contributing to the problem. Keeping the background out of focus while following an actor/object definitely helps.

Short exposure times are bad as well, we need the motion blur of 1/48th to minimize it.
