What does Cinematic mean?
Presumeably it suggests the sort of visual reproduction you see in a cinema. If so, then all films seen in the cinema are cinematic. Are we seeing the same cinematic experience with a misty eyed dreamy romance or a an action packed James Bond movie. Well, that makes no sense, does it. There is no motion blur to be seen in the romance, hell, there is little movement to be seen. Have you noticed how little fast action is shown in the fight scenes of a Bond movie. They are reduced to a series of successive stills like a flicker book, no smooth flow between frames at all. How cinematic is that?
What you need is a high frame rate and a high refresh rate, for crystal clear and super sharp scenes that move.
Did you know that modern TVs and your digital devices have screen refresh rates typically at 60 FPS. Has it ever crossed your mind why they bother when your Cinematic movie is running at 24 FPS?
You do know that the human eye perceieves a movement in a scene of 12 FPS or more as a fluid movement, don't you?
Did you realise that each frame is rendered as a complete frame?
Did you realise that if you play a 24 FPS moving scene on a 60 FPS refresh rate that (60 / 24 = 2.5) you will be getting 2.5 identical still frames showing each second, before jerking onto the next frame f movement? Actually, you can' have a 0.5 frame displayed, so the device has to carry over that 0.5 as another whole frame and then miss out the next 0.5 frame in the next new frame. You see 3 frames of one piece of movement, 2 frames of the next piece of movement, 3 frames... No wonder it is a juddery mess that has to be artificially blurred.
At 30 FPS, you do get a consistent but over displayed stepped progression of movement. That will be 2 identical frames then the next 2 iidentical frames of the moving scene.
At 60 FPS, this will match your display refresh rate and you will see the brilliance of a modern display. Super smooth, super sharp during movement.
Did you know that at 60 FPS for a given resolution and compression, say 4K, you create 2.5 times more data than at 24 FPS?
If you are showing some very slow moving scenery like flying along a coast line at 400 feet altitude, looking forward, then 24FPS will be fine. Better still, you won't need to mess about with those ND filters.
If you are panning and it looks stuttery, you are doing it wrong. Up the frame rate to 60fps, if you must, but don't artificially blur it, it looks poorly done. The human eye will do its own bluring, they are doing it throughout our lives, and with no ill effects.
I ask the questions so you can seek you own answers from scientific resources, not some hand-me-down folklore on Youtube.
