wait seriously I'm going to try it on mine. But does it work with the in build gopro 7 black stabilization turn on or does turn it off?

I've got thumb pro W, after some experimenting i got fewer wobbles with this: In motion data: -load corresponding *.gcsv -0 sync points (remove all points manually, motion data seems to be in sync for the most part, but due to very noisy gyro the offsets are calculated wildly incorrectly) -low pass filter very low (5-10hz) -simple gyro integration

I'm sure it had a hard limit of much less in earlier versions. When he said 500 to me I didn't think it was possible. Double check you are on the latest GyroFlow, and do a quick calculation to figure out what your sync search side needs to be in order to fit 500 points into your clip length.

@cagmuer

Жыл бұрын

When I do a fast flip/roll, I have to do a set of sync points before it and after it. flips/rolls makes gyroflow crazy and it crashes on me. If I do 3-4 of them, then I just do sync points in between them and do maybe 100 syncs each.

Great video, thanks for sharing your findings. I think i have managed to perfect the mount and the stabilisation now but can I ask what export settings you use in gyroflow as my footage looks great in gyroflow but once exported I'm losing a lot of quality. Thanks again. 👍

@CurryKitten

Жыл бұрын

That's weird, I haven't touched my settings - which usually means it's exporting the same as what's come in. So double check your output size is the same as what your footage is shot in - I've usung the H.264 codec. Usually the GyroFlow preview looks worse, it's only at 720p, with the slight issue that this can disguise some small shakes once you export to the full resolution

30 sync points at 1 sec each in a 4 min clip works really well for me. The frame rate drops and glitches are farther apart and it seems way overkill for that many sync points.

@@CurryKitten good call. I printed a mount for the thumb pro but it's to flexible and doesn't hold the pro in the same spot so the angle shifts around noticably. If printed in 100% infill the part where it mounts on the base is still to flexible.

That original TPU mount that came with the Thumb Pro was ok, but it was built for a very specific screw spacing for (I guess) a little cinewhoop or something. If you can get something more bespoke that fits the quad (obviously a 3d printer... or a friend with one is handy) then you can hopefully take away some of those vibes

There's an amount of this due to the compression KZread uses which makes any grass details smooth together in a sort of unfocused haze. But that said, the GoPro goes through the same compression, so there's an obvious winner to the quality in cameras here

I have struggles with the ThumbPro my self tbh on jello.

@CurryKitten

Жыл бұрын

I haven't had actual jello - although this is helped with an ND32 filter and a little bit of experimentation with TPU mounts. It's definitely "shaky" but doesn't have that typical rolling shutter effect. If you can get to at least that, you might be able to smooth things out with GyroFlow, but it's all a lot of effort

@cagmuer

Жыл бұрын

Here's my theory on that, I think GoPros have enough mass that they are their own dampener for jello. And the thumb is so lite that along with the mount it can start to resonate at certain RPMs of the motors. I think a super soft mount lowers the resonance frequency to keep jello under control and then wobbles added by a soft mount get filtered out by gyroflow with these hundreds of sync points. That's my theory.

Definitely looks better but at that point one could go straight to optical-flow stabilization. Looking forward to your walnut review ;-)

@volkergoe

@@CurryKitten It's about estimating the motion between frames by tracking high contrast features - that's how stabilizing was done before we had gyro-data. I think Gyroflow only uses it for the sync points (the yellow lines in the preview) because it hits on the CPU/GPU a lot.

@cagmuer

Жыл бұрын

I had the same idea about 100% optical flow and I talked to the gyroflow devs about this in their Discord and 100% optical flow is not accurate enough to use raw, but its awesome for syncing up with our high resolution gyro data. I know it takes a few minutes but at least 500 points is automated.

Can you tell from the gyro data what frequencies are giving you trouble? Is there a frequency or FFT readout? That could help us say what changes to the mount you should make.

@CurryKitten

Жыл бұрын

Not as such no. I can only say there's a large difference in the sort of vibration frequency that you generate from 2.5" props - where things are pretty tidy, compared with 5" props - where's it's a mess. The Gyro data really just give the amplitude rather than any frequency

I'm currently thinking that its when the motors RPM goes through a resonance frequency of the mount. So the quad is flying smooth, but the mount resonates and give these frames a bunch of motion blur but not really any jello. I haven't tested this idea.

Not much luck with the RunCam Thumb on a Rekon35 -- experimented with a number of different TPU camera mounts, my best result came from a PLA+ camera mount nothing makes sense -- I think harmonics vs propeller size has a lot to do with it, in the meantime I purchased a Hawkeye Firefly NakedCam V4 -- that works great with GyroFlow, and the video looks so much better -- after watching this at some stage I am going to retry RunCam Thumb, probably after experimenting with with different propellers and sizes, maybe you can make a video trying out different propellers and sizes with the RunCam Thumb and see if it makes a difference.

@CurryKitten

Жыл бұрын

Props and the harmonic frequency makes all the difference I believe. When I ran this on a 2.5" cinewhoop I found the stabilization worked perfectly, the gyro wasn't full of noise - it was easy. The vibration frequency that a 5" produces, and potentially a 3" can be a nightmare. Interestingly, the Hawkeye Naked camera is the next one I'm testing, and I didn't get very good results with the two quads I tried initially... I still don't know if I'm that happy with the output. Is does make me worry that there is no one solution and you have to spend time tailoring your workflow for every single quad you have

@cagmuer

Жыл бұрын

I think the motor hits resonance frequency of the mount that video gets a bunch of motion blur but not really any jello. But its not frame resonance so the quad flies just fine. But I haven't tested this idea.

You should turn HyperSmooth off on ALL GoPro's, and stabilise with Reelsteady in the GoPro Player desktop app, or any of the older versions of Reelsteady. HyperSmooth is not optimised for FPV flying, and creates slight "jerky" movements, when you were actually flying perfectly smooth. This usually occurs when coming out of a smooth turn, in to a straight line.

@CurryKitten

Жыл бұрын

What looks good to one person is, of course, very subjective, and to me Hypersmooth looks good, and I like the fact there's no additional post processing to do. Aside from that, while Reelsteady might be part of the GoPro desktop app, it's still a paid extra

@@CurryKitten yes that's true! It does generally do a fantastic job. It's only a small thing, and most people don't notice it.
