How to make 30fps... look like 30fps? (not 'framey')

I've got a niggle about my streams. I know this is picky. But like some of you, it matters to me.

This is not big or important, but I'm trying to understand what the solution is.

My friend streams @ 30FPS and his hands move quite smoothly on his streams. He uses professional cameras (Sony A5100) and Atem Mini.

I have a Laptop with Nvenc Encoder & choice of:

1) iPhone 12 app: Filmic Pro (HDMI Out + Capture Card)
2) iPhone 12 app: OBS Camera (Lightning Cable to USB)
3) Logitech C920 (USB)
4) Logitech C922 (USB)

When I move my body or my arms on these videos, I look 'Framey' i.e. like a bunch of fast pictures thrown together. I'm aiming for smooth. Not really 60FPS but maybe 30 or 48 would be nice.

I've tried OBS and Camera settings at:

30FPS
48FPS
60FPS

FLV Recording. CQP from 22 down to 17, Max Quality and Quality.

The laptop is operating at 60hz refresh rate, nothing else open etc.

The reality seems to be for me that 48 and 60FPS barely look any smoother than 30FPS. I feel like my the frame rates when I set it to that looks closer to 20 but I believe the graphics card can handle this.

There is one weird exception - at 1080p the old C920 camera pointed at the DJ equipment looks way smoother during movements when you see my arms/hands.

I've been trying to avoid spending on the Atem Mini and a new camera as that veers into somewhere below €1000 and the gains are minimal. I'm a believer that it 'can' be done and I just don't know how.

Live Example: Notice at first I'm slightly jotly when I am in full view (watch my hands, then notice how much more smooth it is on the camera pointed at the equipment)


Is there anything I can try with this equipment to smoothen me out or do I really need an external encoder?

Video looks good, you need to know a bit more about filming, such as aperture, shutter speed, iso and a few other little things.
it is very bright because of this cameras usually reduce the shutter speed, it may seem that the movement is not smooth. The way to do it - apply the ND filter, there are fixed value and variable filters.
Set the shutter speed to 1/120 for 60fps or (1/60 for 30fps), then select the appropriate ND filter so that the image is not burned out, simple filters cost a few euros.

I’m excited to try this out - thank you!

I’m not yet of the skill set where I know when to decide to use these but they have come onto my radar recently. I didn’t know for 60fps you would need 1/120 Shutter which is a great tip.

Now to find where ND filter is...

Just found out what you mean about ND filter. Glad you reminded - We used one of these for a DSLR to shoot real estate photos (it basically stopped the windows whiting out and we could take bright internal photos with blue skies). Thanks so much :)

Your advice really worked @Tomasz Góral . This is a recording from Sunday gone, on just 30fps. Much smoother.

I will be pursuing 48fps @ 50hz but for now this is great!
