Great video Michael! May be worth mentioning that this only works with BRAW, and having tested on my side, I also encountered the same awkward results you had after processing a shot and it still looks like vertical lines are tilted from the rolling shutter - turns out that's actually from the camera itself being tilted on its roll axis when you did the erratic movements (you can actually see it in the gyro data graph). Should you try that test again with the camera on a tripod you'll see the RS correction works very well 🙂
The other good news is that it also works very well with anamorphic lenses (albeit you need to calculate a corrected lens data to input for it to work), which really gave me hope to going back to this camera for anamorphics
Yeah! Figured the issue was my crazy hand movements haha a tripod would have made it more scientific. My 3am brain wasn’t thinking properly I guess 😅
LOL, I noticed that on launch day and have been loving it since I commented on a bunch of videos pointing it out, but no one ever noted it until now!
Ah, yes, as a SteadXP user for years, I was in the forums pushing for them to add both gyro stabilization and angle shift rolling shutter compensation. Just to be aware it can't fix rolling sutter on moving objects within a static frame, or at least not without a little AI/ neural engine involvement. For what it's worth one could also technically get near perfect post motion blur from the gyro data as well if they wanted to implement it; however, I'm not sure if Blackmagic uses the gyro data along with the pixel data for the Davinci motion blur motion vectors, but if they did, then using a lower shutter angle to compensate for the hand held micro jitter moment, which typically destroys the 180 degree shutter, could be returned to a 180 degree shutter fairly easily in post.
You got my attention!
Tell me more.
Where can I read up on this?
@@G_handle I'll try and explain the theory to save you the trouble. If one knows the focal length and sensor size of the camera in conjunction with the relative position of the camera then there are techniques that can be used to figure out the relative distance to objects and create depth maps. (edited additional note on this to calculate a fairly accurate depth map one needs a few frames of objects offset from one another, and that happens a lot with video footage) DaVinci Resolve can already do the depth maps to a reasonable degree. The motion blur is a combination of the physical object movement from frame to frame in addition to the relative camera movement from frame to frame. We know both with gyro, lens & sensor data, and unlike simulated depth of field (aka what iphones can do) motion blur blends uniformly in botth directions meaning there is no hard pixelated edge like with depth of field. AKA we can literally calculate near perfect motion blur in post thanks to gyro data.
To nip a related question in the butt ahead of time. Yes, one can do motion vector motion blur already inside Davinci Resolve on the color page, but I don't believe they've added the gyro data into the calculation as of yet, but I don't see why they couldn't.
@@billyoung9538 yeah there are a few things they could do with gyro which they don't - seems like it would be possible to do handheld sky replacement from the gyro data - since it's far enough away for position not to matter?
There was someone on the BM forums asking about getting gyro data into Blender, but no idea if they got anywhere with it
This isn't new or hidden. You just wasn't paying attention. Blsckmagic released access to gyrodata last year.
Gyrodata stabilisation is not the same as rolling shutter compensation
So what part of setting Gryo to zero strength was well known. Why do people always miss half of what’s said? Do you people really pay attention?
This isn’t about gyro stabilization
Yeah Michael did a video about that when the gyro update was released.
The excitement and confusion here is that rolling shutter was remedied by that update, but not explicitly described by bmd as something that would remedy rolling shutter. Rolling shutter is not even addressed in the patch notes. Meanwhile, people are ALWAYS complaining about rolling shutter these days (because we’ve run out of things to complain about I think), and this was apparently an obscure fix the whole time. Wild…
It’s okay. I always forget to wipe.
In the original video by diode it zooms quite a bit but if you shoot 6k with room you could accommodate for this.
However a better solution may be after effects rolling shutter repair which fixes it without any zoom, somehow. Fusion doesn’t seem to have an effect like this strangely.
Michael, this was gone over in detail recently in a CVP review if the new Cinema Camera, and it had a bunch of footage examples.
Hello good afternoon. I have an acmaera balckmagic 6k pro. I've been having some problems with the recording. After about 20 consecutive minutes of recording, the machine stops recording. I record in maximum quality 6k. recording is to a 1 TB Cruxail x6 external SSD disk. I've had the machine for almost a year and a half and never updated the friware. I would like to know if there are more reports of this problem and how it can be resolved. Thank you for your help.
What if you have a zoom lens, do you have to put the focal length?
You might also want to mention that you don't get gyro data recorded if you're using a lens with stabilization and it's turned on.
The ability to not only stabilize a shot from a BM camera but reduce rolling shutter is an amazing find. Having had the BMPCC4K, I know how much I miss working with BRAW.
Now, I know the word "cinematic" is thrown around a lot these days. But, to me, the BRAW footage coming straight out of a BM camera has a very cinematic look. Color wise especially. This discovery has caused me to reconsider BM camera again. Why BM hasn't called out this feature is truly baffling.
Well said! Fully agreed 🙌🏼
I have BMPCC4k for I think over 2 years now. I am yet to find a camera that gives as HQ, film-like image at this price level. It's truly amazing. And I really am doing almost constant research.
This is a very controversial topic. The rolling shutter correction algorithm demands low speed/frequency of vibration of picture frames like your hand-holding of the camera. Any flight envelope outliers, as in sports and aerial photography, create jello artifacts with the algorithm that are more offensive than the familiar slanted pictures that we know to tolerate. There are many discussions out there against turning on the algorithm at all costs.
Wait…. If the camera can shoot at faster frame rates than it must be able to record pixels on the censor faster. In that case BMD could create a preset that films at a faster frame rate and then downsamples to 24. Rolling shutter gone, the files will just initially take up more space and have less motion blur.
You could do this manually by filming at a speed that’s a multiple of 24 like 48 and then speeding the resulting footage back up to 24. Then you could add motion blur with an effect if you want.
This is based on the assumption that the camera doesn’t time scale up the sensor pixel sweep in slow mo mode. Because why would they do that?
I’m going to do a bunch of tests with my 6K G2.
Very important to realize that this doesn't fix rolling shutter issues that are caused by something else than the movement of the camera. So for example if you point the camera out of the window of a moving car the lamp posts will still be warped!
Point the camera at the propellor of an airplane and it will still be totally warped.
YT'ers try to bring this a magic trick to turn this camera into a GS camera, but it's simply not.
Hi can put programs vivid capture photos on this camera too blackmagic pocket 6k pro this is amazing too even lot too that the special of this camera of it .only colourist can does these things too.
cool.... thanx
There is no option for camera gyro in the free version of DaVinci Resolve. You should have told us that.
You can only use it if you record in braw. And braw is a codec from BM cameras, and BM cameras come with a Studio Version...
It won't work if it's not the camera what is moving in the shot though.
Blackmagic firmware updates, the gift that keeps on giving... then keeps on giving... waiting for the coffee and cookie oven update.

- 🐧
This is actually super impressive
Right?!
@@initialfocusWhats going on with the shipping for the T7 grip? Its been over a month with no shipping yet?
@anthonychinyere7259 if you want to DM me ur order number on insta or X @initialfocus I can check with cliff. I know he just sent out a bunch today and more are going out every day this week.
thanks man
thanks, and I subcribed to diode
Noice! 🙌🏼
I saw his video randomly and lucky 😅
Pretty sure BM didn’t knew about it
☕️👍
☕️ 🙌🏼
Not a good example waste of time
you think that’s improved? Rolling shutter? I think it looks like shit. Rolling shutter. Makes me crazy. Nothing like the Komodo X…
Great, enjoy.
I heard about it a year ago from @Ant Pruitt .. I thought everyone knew but hated it bc of the zoom lol
Hah I mean it barely zooms and especially anyone on a Pocket 6K (Pro) can afford a little crop since most of us output in 4K
Lol I agree, it didn't bother me bc I mostly use wide angle lenses so I barely saw it.
