Honestly the friendship Gerald Undone and you have is so goddang wholesome. But more than anything, each of your film tech videos are pure unadulterated storytelling and I love it.

[@KlockworXMusic]

So I use a LiDAR scanner for work to make 3D models, I can tell you the best surfaces for LiDAR are retroreflective. Mirrors and material that absorbs alot of light are very bad. The LiDAR emitter and receiver are right next to each other, so light has to be reflected back to the source, which is why retroreflectors work so well, and why mirrors don't work at all. For most materials that scatter light in all directions, you want it to scatter as much light that hits it without absorbing too much. The LiDAR they are using is orders of magnitudes cheaper then what I use, so your mileage may vary, but for calibration try using a retroreflective piece of tape on a wall, and same for shots where its having a hard time focusing, put a piece of retroreflective tape on the subject where you want the focal plane to be, even a small piece should have such a high intensity value that it blows out the averaging the software is doing and it should lock focusing on the retroreflector. Mist, fog, dust and similar don't play nice with LiDAR as you found out lol Hope this helps.

[@MAKEARTNOWCHANNEL]

Super valuable!! Thank you so much for dropping the real science on this!!! If you have any other ideas, fabrics or broad spectrum sunblock that may help, let us know. I'll pin the info here. The idea of having some more tools to make this work better, without compromising the shot--- reflective tape would be great, but how would you hide it on the subject? Thanks yo!

[@KlockworXMusic]

@@MAKEARTNOWCHANNEL No problem, honestly thought this would just get washed out in the sea of comments. I will give you a bit more insight and the method I would use to test this. We use retroreflective paint and tape for reference measurements and for locking in surveyed points. We do this because LiDAR reports intensity values along with distance, and when we adjust our point clouds for intensity, our reference markers have way higher intensity and stand out. I would start by getting a roll of retroreflective tape and seeing how it reacts to it and with different sized pieces. If it works well there is retroreflective fabric paint, you could use this to go over a design on a piece of clothing with it, that way it's visible for the LiDAR but doesn't look out of place for the shot. My favourite jacket has a mining company logo in this type of fabric paint on it, and when I wear it into public bathrooms, it will set off all of the hands free sinks, soap dispensers, and hand dryers simultaneously; this was also very spooky at first. The nice thing with retroreflectives is they shouldn't bother the camera and the shot, since they send light back to the source, assuming your light source isn't very close to the camera, they shouldn't show up on camera as a bright spot. If you try this out, post a reply, I would be interested in how it turns out. One last note, if you are curious figuring out what materials work and what don't, since you seem reasonably tech savvy, you can get a single point LiDAR like a TFMini for like $20, add your microcontroller of choice and some code, and a display to have it display its intensity values. Then from a similar distance each time, point it at different materials and check intensity. Higher intensity values, the better it will be for LiDAR.

[@fuckpoasting]

​@@KlockworXMusic on the last note, if you were to build your own I'd be really curious to see if the performance can be augmented by using a sonar system if the LiDAR system is struggling, especially if its

Josh my brain is still trying to grapple with this concept of LiDAR autofocus and you may be right this could be the next evolution in filmmaking (e.g. DVX100, 5DMKII, sliders, drones, gimbals etc.) Everything you are doing is cutting edge right now and I think you're definitely in the flow right now and I'm looking forward to #anamorphia2

[@Diro_Nikhil]

That shot at Golden Hour light 16:39 with the baby is just Pure Slo Mo bliss !

[@kaneschirmer2782]

Here's something for you to try...If you want to keep your subject on the right or left of the frame (say documentary or a conversation for a film where you're cutting back and forth using the 180 degree rule - Can you simply mount the sensor on a rail - right or left of len -, so it keeps the subject (right or left of the lens) in focus?

[@MakeKasprzak]

Would be cool if it could temporarily change the light color to something in the visible light spectrum, so you can make sure you and the sensor are pointing the same way by looking at the screen. I could easily see the angle being off slightly due to how it sits in the shoe.

[@ILOVESHOOT]

[@JDRBNFB]

I suspect the issue with things like brick and concrete is not absorption but diffraction. Tiny imperfections in the brick, bumps, holes, even some that are probably close to microscopic, are going to be very close to the wavelength of the IR. Imagine what happens if you shoot a watergun at a window screen - The water will turn from a steady stream to a cone of mist - the same thing is happening to the IR against those surfaces - it is reflecting - but it's not reflecting efficiently enough for the sensor to read it.

[@MAKEARTNOWCHANNEL]

Good point!

[@redstonemedia4410]

A few days ago I was able to buy it. Found this in Denmark. Last. Maybe the only one in Scandinavia. Not available in any store in Sweden. A very strange feeling when the Sirui 50mm on the BMPCC4K catches the focus better than the Fuji X-T4 (I know the autofocus on Fuji is ... unpredictable, but there is some). And I love the RS2. Great channel anyway. Thanks for all the advice and tutorials. Great content. I love that you go for quality not quantity. You're great, dude. Cheers.

[@Edward_Black_Rose]

Two small cheap cameras can be used instead of infrared. The principle of operation is the same as that of human eyes and the technology of the old rangefinder camera. It's just that the cameras need to turn quickly to each other, and the software needs to recognize where the images overlap. This also makes it possible to detect faces. As well as for fixing the focus on a specific point. Another very cheap and simple option is to use ultrasound, the problem with it is that the device will not detect small objects and will always focus on the background.

Hey ! Infrared are influenced by the material density. Also some natural stones like granit or marble absorb energy and emit it in infrared, put your hand on granit wall at the end of a sunny day, it will feel warm. I think concreet acts a bit like that.

[@TheAaronalden]

This is incredible... for the price of a nice new fast lens you can buy the gimbal and some nice vintage glass... what an incredible time to be alive! I hope they make a stand alone version, but I feel like a gimble is going to be a permanent part of the kit anyway.

[@trystanmentoor4740]

Try searching for a Total station prism I think it could work out to help focusing. The total stations use a laser in the same concept as LiDAR. The laser shoots from the TS to the prism and reflects back to the machine to tell you the exact distance etc. Leica is the manufacturer of the equipment I use. If you have a friend in construction/civil/earthworks they should be able to help you out. There is also a mini prism which can fit in the palm of your hand.

[@xcitelight2192]

Maybe you can change to a larger gear wheel to the motorunit to solve longer focus throws

[@Ben-rz9cf]

technical gripe here; TOF is not LiDAR, they're separate technologies. TOF is basically the kind of depth sensor you'd see on iphones BEFORE they put in the LiDAR sensor. fixed light sensors (like kinect) project and track infrared light fields, TOF sensors on modern smartphones use infrared pulses (kind of like echolocation) and LIDAR is basically a laser reconstruction. The distinction is important because you might find with multiple cameras with multiple TOF focus systems they could interfere with each other and your shot could get fucked up.

[@MAKEARTNOWCHANNEL]

Love this distinction! Care to chat more on this? I have the new RONIN4D which has a much more advanced lidar unit and would love to know your thoughts if you want to discuss. you can DM me on IG if you're down. Thanks for the input!

This is revolutionary, do you think they’ll make available a stand alone auto focus system for manual lenses without the gimbal? DJI + Awesome = Make Art Now

[@JTMagee]

For being in its infancy stage, there is really cool potential with this. Granted, I'm still very new to creating film and video myself, but seeing where this will go definitely gives me a lot of ideas for future projects. As well as where I save for certain products. In regards to the haze being in the way, it might be an intriguing idea for DJI to reach out to various marine biologists and biologists to research how whales and bats process echolocation to find their way between travel and food. After that combined research, DJI could then find a way to code that into the LiDAR-based tech to improve how low end sensors can pinpoint harder surfaces as the focal point for shots that have haze, fog, smoke or anything that may get in the way of a focused shot or clip. Really cool to see the test footage with older lenses. Thank you!

[@DehinorVargas]

2 real facts, 1- that LiDAR sensor is awesome but needs some improve. 2- Heraldo deshecho talk with awesome technical property.

[@stevenmattson3164]

The soft push ins and outs might be rested to the motor’s inability to move the lens fast enough to keep up with your moves. You can see in most instances of your tests, the focus was sharp a moment after landing at the end point. This is a common problem with any remote focus system.

[@zachschermerhorn8090]

Imagine the future of this thing! I want to see one that goes right into the camera and allows for touch focus. Even if you can get an external monitor that you can touch focus with that would be tight.

My next goal would be the medium film format lenses Pentax SMC 67 45mm 1.4 and of course my Pentax SMC 67 105mm / 2.4. But these are already very specific narrow angles when converted. I am trying to work on a system that would be able to focus small barel lenses, I have fantastic copper ones, placing them on a cranted "chariot" which would be actionned by the focus motor.
