Hi Eric,
Quick question on that, when overcranking, say shooting 60/30 with the intention of going to a 30 FPS timeline, would you be suggesting a shutter speed of 1/60 or 1/120 for the most pleasing look that you mention. In other words, is this based on shooting framerate or timeline/playback framerate?

If you use angle mode and keep the shutter at 180° the shutter will always be correct for the "pleasing" film look.

At 60 fps that means a shutter of 1/120.

Got it. I have no experience here so I guess my question was, is 180 degrees (or shutter speed set to half of the frame rate) still considered pleasing when the playback frame rate is slowed back?

Yes. "Pleasing" being subjctive, of course.

It's the "duty cycle" of the motion blur of film shooting that you are matching.

50% motion blur and 50% gap between motion blur. As the film shutter spins around 360°, half of it is open and the other half closed to allow the film to be pulled through the gate.

It's become the generally accepted compromise between blur and strobiness, and especially applies when the finished product is 24p.
