When we are shooting "creative b-roll" with prime lenses.
We shoot on Canon C300 (original model)
Sometimes the client wants 1080/29.97p as a more filmic look even though when it is broadcast it is 720/60p on the network.  (1080/29.97p @ 50Mbps 4:2:2 MXF file)
We will sometimes use a tripod & prime lenses for this "creative b-roll" and try to use f/2-f/2.8 and go with a 1/48th second shutter speed for which gives us the ‘film look’ appearance of motion blur from motion artifacts similar to shooting 23.98fps with standard 180 degree shutter.
Sometimes we will lower the black gamma for more toe contrast and "crushed blacks". We choose our camera profile and bake it in with whites clipping at 100% IRE broadcast legal as The client doesn't want to do color correction/grading. Sometimes we reduce sharpness in the Custom Profile.
Sometimes we use Nikon stills vintage prime telephoto lenses like a 180mm and put some christmas lights in the background for huge globes of spherical highlights.
Sometimes we'll bring up the ISO to 4000 to get some of that noise moving around as a film grain simulation. Sometimes we'll also use some noise reduction to help it not look like video noise.
 
I was wondering do others do these things also?
Since we are shooting on the original C300 we cannot do slow motion at 1080/30p even a small amount like 36 frames using 23.98 at fps.
Other than starting to use a slider for slow Left-Right  or slow forward-backward in/out camera moves while not adjusting the focus so the subject comes in and out of the focal plane would you share any other tricks/techniques that are mostly NOT done with lighting for a more filmic-look when you have to stick to the producer's in-camera format of 1080/30p using a Super-35mm sensor camera?

If you can persuade the camera to do a more gentle highlight rolloff, that'll help, though you would then be tinkering quite significantly with the way the thing works, so go carefully.

 

It is very difficult to make 30 look like a real movie. I guess ideally you'd shoot 24p, then have it converted up to 60, as the 3:2 pulldown (or more accurately derivative thereof) will be visible and give it a movie look. I'm not sure that many, if any, cameras can actually shoot like that, though it would be reasonably easy for post to do it.

 

Looked at filtration? Hollywood Black Magic, grads and polarisers?
