Super slow motion settings

Hi Guys,

I'm filming some footage that I want to then make Super slow motion in Twixtor.

I've read a lot of conflicting advice on what's the best settings to use to capture the footage.

I'm shooting with a Canon 5D Mark III.

- 50 FPS 1280x720
- 1/1000 Shutter.

Is there anything else that I should be aware of to get the best footage?

Thanks in advance.

I am glad someone brought this up...because Ive been wanting this answer for a while.

Does shutter speed affect slow motion? Cause I really don't think it does. Lets think about it.

FPS is basically shutter speed when doing video. Notice how you can't got to a slower shutter speed when filming at 30 fps. it just doesn't happen, because video is being filmed at 30 fps. so what about having a faster shutter speed when filming at 60 fps. (lets say 1/1000). Would each frame be a clean frame with little to no movement. Also....i dont hear the lens closing and opening while i am filming...which is what shutter speed is controlling if i am not mistaken. the only thing your doing by going to a lower shutter speed is letting less light in....which i dont even know if thats actually occuring in the video, it may just be telling me visually on the screen and when i film it it really has no effect whatsoever. anyone want to comment? i guess i could just get off my ass and figure it out myself.

Also, to answer your question.....super slow motion is really hard to achieve with 50fps footage and twixtor. There are certain things it will work fine on...but the basic way to figure it out is...if things are moving quite fast...it probably won't look good. if things are moving at a normal pace, twixtor will do a decent job.

Faster shutter speed means less motion blur. This can help when using optical flow because it can be easier for the algorithm to predict motion to create new frames.

Shooting slomos with the FS700 I made the experience that less motion blur results in sharper, crispier slomo. So yes, I like cseeman think that shutter speed does have an impact on the results.

I'm curious to hear what you found out yourself, though.

ON my 5D Mark III, this is what I found.

50 FPS makes a difference.
Increased shutter speed and then either lighting the subject or bumping up the aperture makes a difference with motion blur.
Making the subject and background plain makes a difference.
If the subject is super fast (free fall) - You're f*cked without more FPS.

I experimented with Optical Flow, Twixtor and deinterlacing, then optical flow.

Those are my findings.

If anyone has anything else they can add, please let me know x

I have found that having lots of light and a very plain background, like the sky or a flat wall hides the "morphing" when using optical flow.
