I thought I would put out a question if others are testing settings. I’ve found that the hypersmooth kind of breaks down in low light (it gets a jittery look more like an extreme eis I expect). It seems to happen when the shutter speed goes slower than 1/120. My solution to this is to use pro tunes in low light situations to fix the shutter speed to at least 1/120 (along with flat color and limit iso to 800). It works pretty well apart from the noise which is to be expected.
My concern though is since I can’t always tell what the camera considers “low light” and slows the shutter so I may not think to turn on pro tunes. You know, like when you are indoors and your eyes are all adjusted and it seems pretty light. I tried using auto low light (which actually seems to work well though it’s counter intuitive). I’m just afraid that I’ll forget or not realize I need to turn on or off the shutter speed when I’m changing situations.
So, I guess I wonder if anyone has played around with this. I kinda wish the was a limit to shutter speed so I can just leave it like iso rather than setting it. Also, I wonder if just running things through a stabilizer after shooting if it will get rid of the jitters and I wouldn’t have to worry so much about it. Or something else I haven’t thought of.

Yes I would like to know the answer to this also, as soon as I went into the woods on my bike the hypersmooth went aweful to the point where the video was not usable.
Does anybody know the best settings?? currently useless for what I use it for most.

Hey. This this is the same Problem I have .
When mountain biking I have some really annoying "micro stutters" I tried every frame rate and setting. But it's all the time the same.
I'll post some videos later.
I used settings like
4K / 2.7K
30FPS / 60 FPS
Iso max 800
White balance native

Also I don’t know if you’re using a chest mount, but I have seen a tip to mount the GoPro below your helmet and that will help with a lot of the jarring movements that create the stutters.

thanks for your replys.
Ive upload a little test video: https://youtu.be/U53FlX7yM2w
Here you can see That it has its "Micro-Stutter".
Its chest mounted. I want to try Helm mounting next... But yeah...I really didnt know if its the camera or me doing something wrong.
It was not really dark there...
Again My settings I used in this clip
Iso max 800
White balance native
I have some other clips in 60 fps - But it´s the same. So I think its not the frame rate what is doing those "Stuttering"
Would you say its better to go with Superview instead of WIde? 30 FPS needs less light, I think 30 FPS should be ok.

So, I want to clarify I'm talking about shutter speed and not FPS.
While they are related, the auto shutter speed will still slow down below 1/120 in low light even if you set your FPS to 60.
The shutter speed is set in the protunes setting just to the right of the protunes toggle. In my testing it needs to be set to at least 1/120 for hypersmooth to work. The higher the better, unfortunatly you can not limit it so there is a risk of overexposing if it is set too low.

yeah I know that you are talking about the shutter speed and I know what you mean with it.
"Normally" you would like to have something like what is called the 180 degree rule.
So for example If you shoot with 60fps you want to have at least 1/120 in shutter speed.
My setting was set to auto....So i def. will try to fix it to 120 ; also when filming in 30 fps.
I also mounted a gopro mount to my helm now...will try this also next time and will test if it will be more stable.
Btw: When setting the shutter fixed to lets say 120 or 240 and tell the camera to EV -1 -> most of the time it should be okay then and not overexposed....just my thoughts?!
Another thought: When fixing the shutter...maybe push the iso limit to something around 1600? I could live more with a little bit of noise (Can denoise it in post) than with shaky, "waggly" material
