THE DEFINITIVE GYROFLOW TUTORIAL

[@blackmennewstyle]

That's really impressive, these guys definitely need serious donations. The FPV Gods forever bless the Open Source community, these guys have been giving so much to the RC Hobby

this was very useful, I feel confident diving in. As an online marketer I wanted Gyroflow to know I heard first about them from Nurk, forgot the name of the software when I needed it and came back to the channel to refresh my memory. Thx Nurk

[@BOTGRINDER]

Perfectly explained, thank you! Im off to try this.

Just used gyroflow for the first time. This content has made the process possible for me to understand what does what and how to use my gyro data and video together. You're the man. Added a lens profile for my ancient history gopro hero4 session to help support the peeps 😀 👍 lol now my old skool session cam has stabilisation ☺️ 👍👌✌️

[@somatic.cinema]

This is great, thank you! I'm curious about the horizon lock setting. I have struggled to get a consistent horizon lock without the frame "clicking" in and out of a level horizon (even with gopro footage)

[@mjodr]

Thanks for this. This info really holds up even now all the way up to version 1.5.x. I was watching "tutorials" from people who don't really know what they are talking about and probably only used it once trying to explain things and it wasn't helping. You actually understand how it works, which helps.

[@villadante]

Wow using an action cam as an external gyro for any type of camera is a game changer! Thank you!!

[@andreamarcovaldi]

Just received a brand new osmo action 4 and i was looking for a tutorial like this! Thank you so much! Cheers from Roma Italy from a new subscriber!

[@stevefines1887]

Great video. This helped me a lot to understand what I needed to do for trouble shooting. One thing on the UI - on the upper left of the frame that contains the gyro and optical flow data are the letters "x,y,z" oriented vertically. These are for the gyro data. The ones on the upper right of the frame are for the generated optical flow data. When trying to correct a sync problem I've found it much easier to toggle off the ones I don't need. As well if you are trying to figure out the orientation for a data logger that is in a non-standard orientation this can help to simplify the channels and see what you are looking at.

[@AdrianoCasemiro]

It's complicated when you don't know how to do it. Thanks for this very concise yet thorough tutorial on the Gyroflow.

The word you are searching for @16:00 is Quaternion and Euler values ;) x,y,z is Euler and is the direct interpretation of angle around these axis. In Quaternion it is different and you cannot directly interpret it to the roll, pitch, yaw axes .

[@wilmesz1992]

Thank you very much for this tutorial, I had figured some of this out already by messing around and reading documentation, but was still blindly bulldozing my way through much of the UI, this really helped me fine tune my stabilization.

[@tommcmannfilms]

This was immensely helpful. Thank you for taking the time to make this video!

[@RGMGFitness]

So much changing so fast with all the new 'stabilization' software. We've got the new GoPro ReelSteady 2.0 (released Friday 4/8/2022) and GyroFlow (v1.0.0-rc5 (March 8, 2022)). Hard to know which is better right now. Haven't tried GyroFlow yet...just doing some research...thx Paul!

[@TobyWallwork]

This was great. The best demo of Gyroflow to date.

[@throughmyeyes4]

I have a sony A7iii is there a way to attach my phone to the camera and get the gyro data for Gyroflow?

[@IvanRayBalais]

This is a very good tutorial love it, thank you for sharing your knowledge to us

[@cineflight1171]

In the calibration process from steadxp it was recommend to fill the frame as much as possible with the chart so I think it is helpfull in gyroflow too. So there shouldn’t be only a little quarter of the chart at bottom left for example - instead go closer and tilt the camera from bottom left to fill the frame more. I think this gives better data for the correction of the distortion of a lens. But maybe I‘m wrong..

[@NURKFPV]

Gyrfoflow recommends you start filming the frame and also get some frames from further back.

[@Entropy512]

@@NURKFPV It's not in the official GF documentation, but many OpenCV tutorials (Gyroflow uses OCV for calibration) strongly recommend having some angled shots of the target. This helps get a much better focal length estimate.

[@AdrianEddy]

Yes, angled shots help, but don't make the angles too extreme

[@dududu7694]

I'd like a tiny standalone gyro+blackbox recorder, to put on nano cars, or tinywhoop. To stabilize footage from older Runcam/Caddx split FPV camera. Like a board which takes 1S voltage, has a gyro, and record data to a flash chip or sdcard slot. I hope some brand would create that.

[@franborrero]

Excited for this one!

[@twzted_synapse221]

Dude, INCREDIBLY technical with all the "left side" settings. What if I just use an Avata and just want smoother footage, do I have to adjust all that?

[@YamilSunRay]

awesome video! How does it work with a full frame lens? can one use just a random chessboard in the same aspect ratio as your full frame? asking for the BMCC6kFF and some 7artisans lenses

[@DJ300fttkl]

Hey, if you have a zoom lens does the calibration of the lens also apply to the full vocal length?

[@zhaooskar3178]

same question

[@NURKFPV]

Yes very much

[@abueromonsele7036]

Very insightful and educative thank you so. My question is can gyroflow be ideal for mobile phones videography? (See some cope of phones it can get the len profiles).

[@strawhatsam]

Wow this is amazing. I can already tell it's gonna be so much better than working with SteadXP. The GUI actually makes logical sense to a user and the dynamic zooming is super useful.

[@GBUKMilo]

Thanks for all that together 🎉

[@NightRiderFPV]

I did a back to back edit with hero10 footage of high speed nascar chase and gyroflow was noticibly worse on horizon shakes. Stability was good but just not that reelsteady glass

[@skygarden]

ok so it’s been a sec, but I’m struggling to use 1. vintage manual full frame lenses, 2. without existing lens profiles, 3. WITH an additional speed booster with 0.726 crop factor, 4. on Sony APSC sensor with 1.5 crop factor. Sometimes I want to stabilise old footage with no lens data and I don’t even remember which lens i used. I’m currently attempting to stabilise new footage shot on a sony zv-e10 (famous for rolling shutter). It does not have In Body Image Stabilisation, and the lens combination is a super takumar 35mm f1:3.5 lens going through a Zhongyi Lens Turbo ii focal reducer. For “Lens native focal length”, I’m entering 35.00mm. For crop factor, 1.09 (I multiplied 35 x 1.5 for the apsc sensor got 52.5mm full frame equivalent, then multiplied that by the 0.726 crop factor of the focal reducer and got 38.115mm full frame equivalent, divided that by the original 35mm and got a combined crop factor of 1.089, rounded to two decimal places 1.09). I made a checkerboard lens calibrtion video but the app doesn’t seem to like its 999 rejjetion error with 1 good frames. I’m not even sure if that’s necessary because I have no intention to correct the lens’ distortion, and I don’t want to lose a single row of pixels unnecessarily. All I want to do is reduce shake from my clumsy body and rolling shutter from my sennsor’s sluggish scan rate. So far I’ve felt pretty at the mercy of the app, without really having much control over what it does. Using desktop and ios versions. Anything you can do with that? I’ll just be over here rewatching the video until it hopefully sinks in or i fall asleep again

[@662SSIPPI]

great informative video thanks.

[@nes.torfernandez]

I feel like a pro thanks to Nurk lmao Out of joke gyro is a great tool, I do fpv but also scuba diving and lots of people used GoPro as their main camera for video and since I post about it on the Facebook group it has help so many people, some of them already donate to the cause.

[@crank_FPV]

For some reason I’m not getting results I need yet but I know this video will get me there! I’m not seeing the gyro data in the lines like you but I’m thinking my footage might be so shaky it’s not able to get smoothed 😂 with stabilization on its worse than without so know I’m off somewhere though still

[@ianyunis3580]

If you calibrate a zoom lens, and for example you only used the lowest focal length in the range is that the only focal you can use? Does calibrating support zoom ranges?

[@TimBelchamber]

did you find the answer to this?

[@ianyunis3580]

​@@TimBelchamber Best bet is having to set up a preset for each focal, like max and min, maybe one at middle and making sure the lens is set at that before flight and not a random in between in the zoom range.

[@TimBelchamber]

@@ianyunis3580 this is also the conclusion I’ve come to. Thanks for the response!

My newbie question: if using a gopro for both video and gyro data do I turn off hypersmooth? And for a quad and hero 8 do I want a rock solid camera mount to the quad or something shock absorbing?

[@ValleyFPV]

Thanks for watching. You want a very solid mount..with some micro vibration absorption pads. That works well. I use a TPU 4d printed gopro mount but use some soft silicone in-between that and the frame.

[@hchattaway]

Maybe i missed it, but it is best to turn off all of the GoPro stabilization and have it just record a normal video? if it's stabilization is turned off, does it still write to the video file the gyro data? Thanks, awesome tutorial and amazing software!

[@besilikum]

Really helpfull! Do i need to create a new lens profile also when changing from 30fps to 60fps or with different focal lengths on the same lens?

[@cineflight1171]

Can‘t wait to see it. Gyroflow is the future

[@FPVenius]

I wonder if the "fourth axis" that GoPro captures is the camera orientation, since it detects and determines which way is up based on when it is powered on (if it's in auto-rotate mode.) That would be important to know if you were doing horizon lock, e.g.

[@AdrianEddy]

no, he talks about quaternions there en.wikipedia.org/wiki/Quaternions_and_spatial_rotation

[@FPVenius]

@@AdrianEddy Ah, ok. Thanks. It's been a while since I've done that level of math, but is that implying that GoPro is storing the lateral accelleration in the three axes (x,y,z) and the rotational acceleration as a quaternion? I might not be getting the terms right, so sorry for that. That said, I think I can see why all of those pieces of information would be important when attempting to smooth a video.

[@AdrianEddy]

@@FPVenius Ok so quaternions are what drives the stabilization. GoPro calculates quaternions in camera based on gyroscope (3-axis), accelerometer (3-axis) and probably magnetometer (3-axis). These quaternions are perfectly synced with every frame so Gyroflow just uses them directly without ever looking at raw gyro or accelerometer data. For other cameras which don't calculate quaternions, gyroflow needs to calculate them from IMU data (gyro, accel, optionally magnetometer). This process of calculating quaternions from gyro data is called integration so that's why selecting Integration method: None makes gyroflow use already precalculated quaternions from camera. If you choose other integration method, it will just take raw gyro data and calculate the quaternions from it, but it won't be as accurate as the one calculated in camera. Quaternions use 4 values to represent 3d orientation so that's why he talked about the 4th axis (which is not really an axis)

[@FPVenius]

@@AdrianEddy thanks for the explanation! I'll check out your video on it soon

[@arturobonfil]

hi, great video i just have a question, what are the camera settings for the Panasonic ?

[@jdrone]

I think there is a certain difference between Reel Steadigo and Gyroflow, but I think Gyroflow is good when it comes to setup. And it's free, too. I have a question for you. Can you control the movement of the drone up and down in the gyroflow?

[@shadaiperez]

Love your contact awesome stuff! …. Just a quick tip Golden rule always watch your videos before you upload.

[@Coffee_catsYT]

Thanks for this incredibly useful walk through, which, among other things clarified best calibration technique, prompting me to redo some that I started with. You note that existence of fourth axis in GoPro data does away with need for integration. How about with a Sony FX6, if you know? I assume FX6 would record 4th axis as well, but would be grateful for confirmation, and any other experience or tips you may have for working with this camera with incredible Gyroflow! Thank you.

[@AdrianEddy]

only GoPro precalculates the orientation (the 4th axis he talked about) in camera, all others don't but it's not an issue at all

[@MattBeardsley]

..I'd LOVE to see Red embed the Komodo's gyro data in its recorded clips.. It sounds like the camera has good hardware for it, but that people haven't really needed the data before now. Are there other cinema cameras that already include gyro data in clips? FX6 maybe?

Yesterday, I filmed a proposal in which I had two main set-ups. #1 INSTA360 ONE R on-top of SONY A7III via SMALLRIG CAGE - Levelled Tripod with Fluid Head (buttery smooth footage even without stabilization) #2 INSTA360 ONE R on-top of SONY A7III via SMALLRIG CAGE - Shoulder Rig ============= For #1, it turns out the footage became almost impossible to stabilize with Gyroflow (at least the way I shot it). Gyroflow had no idea where to auto-sync because the footage was too steady to begin with. Maybe next time I need to artificially add some more violent jerking to act as sync points For #2, the shouler rig set-up had no problems auto-syncing ============= IMU = yXZ

Regarding creating a lens profile, it is not working for me. Trying to create one for my Runcam 5 Black (the one without gyro). Wanted to use this camera together with blackbox log for stabilazation. I am following the process accurately, filming the pattern slowly (frame filled, then along all edges into all corners, move back, repeat three times). It always gets 0 good frames in the auto calibration and a reprojection error of 999. I've had great hopes for this programme, but even when using other cameras (Hero 7, hero 4) it did not deliver great results. It's a frustrating mystery to me how others can get such smooth videos out of it.

EXPORT SETTINGS: if the software zooms in i think it doesn't make sense to export in the same settings of the original footage because it would in some way lose quality. am i right?
