I have an OSMO Plus with a z-axis. I have seen footage that is rock solid with this combination.

I have tried everything and can't get it to be as stable as I think it should be. I am starting to wonder if something is not working correctly. The link below is footage with the z-axis.  No matter what I do I can't get much better than that.  Do you think it's not working correctly?
Thanks

It looks like it is still canceling out most of the movement.  Did you adjust the spring tension properly?

Also, it’s not magic, you still have to walk gently if you want it to eliminate everything, and avoid jerky motions.

Yes, I walked like a ninja and set the spring tension many different ways.   
The footage is not even close to being good. I have seen youtube footage where the guy was running with the OSMO and z-axis, it was much better than that.

That's unusable.

What does your OSMO z-axis look like



If you have an OSMO with a z-axis will you please post some footage. I can't get steady footage (see below) for the life of me. Yes, I have tried to walk like a ninja and have experimented with spring tension.

I wondering if it's not working correctly. It seems like the spring is not strong enough to hold up the camera. No matter what tension I set it at it bobs up an down a lot.

Please tell me that it works better than that

Thanks Steve

Honestly, I would be pretty happy with that, your never going to 100% eliminate movement and you have eliminated 99%.  It looks very similar to what I get and what other users have gotten.

Also, bear in mind, that not everyone uses the Go app for their filming, others, like Filmic Pro, have built in stabilization in addition to what they get from the Z Axis.  Then understand that whatever video you watch may have gone through post processing as well to stabilize it further.

Try that same shot again without the Z axis and see what results you get...

I would suggest you shoot one scene with and without the z-axis in order to see the difference. Your footage looks similar to the first time I tried out the z-axis. Practice, practice, practice.

Thanks, I will check out Filmic Pro. Is that an app?

It looks like the Filmic Pro is just for the OSMO Mobile. I have the Plus

You could use an M1 gimbal, but I was just using it as an example, my point was just that whatever you saw may well have used third party software with digital stabilization, or they could have just done it in post production.

Looking at the clip you are getting movement on the left side. The camera is much more sensitive to movement when the the subject is near. It's as if you had a telephoto lens on the left and a wide angle in front. If you look at the center of your video, it's very stable. As I stated in your other post, practice, practice, practice. Another problem you may find with that close and far issue is that it can't be stabilized in post. Again, for the same reason, one part of the video is smooth and the other is bouncing all over the place.

Warp Stabilization in post does not work that will on the OSMO footage.  I think the movement is too soft and slow

It works fine if your subject is far enough away from the camera or if you're using a 25mm or longer lens.

Here's a trick you can use that will help stabilize Osmo vids. Crop your vid to exclude those areas that are closest to the camera, run warp stabilizer and then undo the crop and don't redo the analyze stage. It won't help with the problem areas but it will give you as much correction as is possible.

Longer lens? I did not think of that.  I will try that tomorrow

Hi Steve, do you turn the tension adjustment knob too tightly?
How about its performance without Z Axis? Thank you.

DJI Mindy

Will turning the tension adjustment knob too tightly damage the Z axis?

I will try and see what the footage looks like without the Z axis.

Steve, sorry for the late response.
The balance of Z-Axis should be adjusted to ensure that the arm can move up and down freely without bumping against the endpoint. I mean do no adjust the knot too tightly.
Please refer to the user manual to adjust the balance. z-axis.png
Please let us know the performance without Z-Axis, thank you.

Thanks, DJI Mindy.

I know how to set up the Balance.  Even when I have it set up exactly how your diagram shows the camera bounces up and down with the slightest movement. This movement can be seen in the above video.  I wish there was a way to make the spring stiffer so the camera would not bob up and down so easily.   

I shot the same scene with and without the Z Axis, there's not much difference.

It is supposed to bounce up and down, if it didn’t, it wouldn’t work.

No sh*t

Did you look at the footage? It is supposed to absorb the z-axis movement.  The video is bouncing up and down. If it was working as advertised it would not do that.

Hi Steve, thanks for the update, I will forward the video to our engineers to look into, will come back to you very soon, thanks for the patience.

Hi Steve, I got the feedback from our engineers, it looks like you didn't balance the axis, if you are sure you have already balanced it properly, please note it is still important to control how you walk.
Please walk steadily and make more practice. Thank for the understanding.
