Hi mate, thanks for the video and easy enough to code. Have you found underexposure to be way more sensitive than overexposure? Just seems to be far more limited range on the darker areas
I actually didn’t know this either. I know the gyro stabilization but never knew it would actually fix the jello effect. Very impressive and thank you.
AI helped me to generate code for this. It works nice inside davinci when log converted to linear before the DCTL node. I converted it to .vlt LUT and put into my lumix S5iix but everything is so dark on camera monitor.
This is fantastic, well done! Too late for the download but easy enough to rewrite my own code. Works great in Resolve, however, when I make a LUT the DCTL node is ignored, so I get a LUT with just the CST to Linear. Any ideas why?
When you mentioned focal length of lens and the fact you have to specify that for Davinci Resolve, I immediately thought I cannot use this tool if I use Metabones speed booster with vintage Nikon F or M42 lens. I assume there is no way to give sufficient amount of information for Davinci Resolve in order to do its thing, so its better just assume this method is out of my reach as long as I use the speed booster and vintage lenses. Am I right?
The problem is it cropped right. And if you’re using anamorphic lenses you effectively lose the value of open gate and thus you’re back where you started and might as well use an FX3. Around and around we go. All I want is a perfect camera. lol.
That's why I don't care for nerds who talk about gear, but have nothing to show for. RU-vid is a sea of pixel peepers who have either a portfolio that feels soulless or worse don't even have anything and who talk about specs as if they're pc gamers comparing technicalities of PC components. But the fix isn't a great fix, the image is getting cropped in and you're losing some parts of the image.
This crops the sensor - quite a lot, actually. It doesn't just fix it with no downside. You might as well just shoot cropped and have a faster readout. Also, as you mentioned, it only works for jello caused by the camera moving and the rest of what you're shooting staying still; if what you're shooting moves it will still be distorted. It's all a bit dumb, TBH.
This is bogus. Apparently you do not understand what rolling shutter is. Yes, you can use the gyro for one type of rolling shutter issue, the pan, but what about all the other rolling shutter issues? A helicopter blade rotating, a bat swing, a golf swing, a flash going off, lightning, and countless other situations where the gyro data is useless for that type of rolling shutter. And the sample from CVP as they said, it was minimized but not eliminated and that is debatable because it still looks awful.
It already works with any bit depth. DCTLs use values from 0-1 (0-100%) rather than 0-255 or 0-1024 etc. The Lut issue is due to the way LUTs function with a particular resolution. Using a 66 point cube is better than a 33 point cube (more resolution) but it will never be as good as the DCTL, or as SmallHD's built in functionality.

Thanks a lot! This DCTL is just what I was looking for!
Not my cameras, and even if you did have the range, being able to distinguish betweet +7 and +8 stops above middle grey isn't particularly useful for the scene.
That is super cool. However, if your camera is on a tripod (or not moving much) and a vehicles pass, they will get the rolling shutter and won't get corrected. So it's a partly fix that comes with an intense crop. Still, good to know!
wow! just has this crazy thought about making a targeted LUT for certain log to translate it to EL Zone on any monitor system.... it's real!! thanks so much!!
I have the S5iiX and have been trying to solve this issue as it plagues these cameras also. It's the only problem I have with what otherwise is a brilliant camera. I have another 'fix'. Turn the camera sideways on shots that will produce severe rolling shutter. The problem is due to horizontal movement so turning your camera sideways the rolling shutter will be gone. The catch is of course that you need to crop. If you can shoot open gate it'll give you a little more to crop from. Makes tripods and gimbals a bit fiddly but there are also L shaped brackets for securing the camera in this fashion. We are desperate.
Check out MONONODES tool in there Utility tools. Called -> "EXPOSURE HEATMAP - "Drawing inspiration from the EL (Exposure Latitude) Zone System, developed by renowned cinematographer Ed Lachman, ASC, this tool offers an intuitive, user-friendly interface for exposure correction. Incorporating mid grey and skin tone visualization, the Exposure Heatmap extends its utility, making it an indispensable tool for achieving realistic and aesthetically pleasing skin tones. I think you can absolutely call it something else and get rid of the half stops
Ah, so gutted the DCTL has been removed. That's a huge disappointment after seeing the potential it had to make my life easier. I understand there is a patent, but damn if that hasn't ruined my Monday. Thanks for making the effort @Diodefilms!
Great video still, and you inspired me to replicate a version of my own, this is a super helpful tool for anyone shooting with a camera in LOG. Had no prior knowledge to coding. Took me quite a few days to figure out the coding part as well as all the various Log curve data by the various manufacturers. I created a DCTL that lets you select what Log curve you are using, and I also decided to use the Log curve data so it is not only accurate but also you won't need a CST to use it with. But of course not all sensor performs the same, so adjustments may still be needed depending on the camera you're using. My reference table has data not just for whole stops, but also in 0.1 stop increments. If anyone wants to have a look at the reference table, I can share them. I suppose creating your own version with data available won't be considered breaching of copyright laws right?

Odd that Blackmagic wouldn't advertise this. It seems they have used rolling shutter in their 'stills camera' Pocket style line as a way to reduce the cost but you can quickly eliminate this issue using Davinci Resolve in post. 👍🏻
