Slow Motion at low Shutter Angle

[Brian Bradley]

for a scene in a movie I'm shooting, I want to to make an argument between a couple look hyper real. I've spent the past hour trying out different combinations of shutter speeds and frame rates. I really like this scene from the Irish Man. Does anyone have any recommendations or experience achieving this effect that they can share?

Odd looking movement.
It looks like a combo of lower shutter angle (faster shutter speed), traditional slow motion, and added slow motion in post using optical flow.
I'm not really a VFX person so I could be off but it looks like footage I've encountered or had to create through editing in the past.
Perhaps they saw the footage as shot and wanted more slow motion after the fact (likely after selecting the music) and could only achieve it as a post effect. Conjecture on my part going off of experience but I wouldn't be surprised if it's a variation of this.

On a side note, I didn't realize RED Helium was used (among other cameras/formats) on that film.

Any recommendations on frame rate and shutter angle that I can experiment with? I've been testing out combinations.

You really have to keep experimenting to find what you're looking for.
Somewhat educated guess, 120fps (shutter angle somewhere between 172-144 degrees maybe lower ) and slowing down in post with another 50% in post with optical flow if you like what I perceive to be "weird motion."
I almost feel like the actors were directed to move somewhat slower so that could be in the mix as well.

You can also just try shooting it properly at 240fps if you have the camera and the lighting to do it.

These are all guestimates on my part. Aspects of what you might perceive as "hyper-real" argument scene might be achieved in the lighting (i.e higher contrast), image sharpness, color, and the depth of field. In the end you know what you're looking just have some fun and test for it.

Thanks for your help, I have 3 weeks before my shoot and I agree it's about personal taste. I'll continue to experimenting
