Testing new camera setup!

https://youtu.be/I-ki2l7ZZWwWhat do you think? I still have a lot of work to do creating movement profiles and animating the lighting to go with the movement so the camera doesn't need to go to higher ISOs where the footage gets noisy, but I was impressed with this result (getting as close as my lights and movement system allow) and like so many chronically online, just couldn't wait for the dopamine that comes with showing off. All feedback is much appreciated.

Pretty wild, well done! Looks like you are using a single light?
Honestly, that is pretty amazing. Your movement slow and smooth enough, and lighting and focus clear enough that I think I could grade/purchase from those images without concern. Are there a few spots of improvement? Sure. Is that a pretty fantastic run? I certainly think so.

the other test vids on my channel are using a typical desk lamp off to the side
all the other vids use addressable LEDs to make the light move without actually moving the coin
the video above has the moving lights
the challenge moving forward is figuring out how to best move the lights around as the coin moves to show the coin in all its glory but also simulate tilting the coin in hand at your desk under a lamp
ultimately the goal is to build a kiosk that I can take to coin shows where you can walk up and stick your slab in and get a video made. Since programming the lights and coin motion have infinite possible combinations, it's tempting to have it be like a game where the player (if they want) can opt to control the motion and lights themselves with some joysticks and have some way for everyone to vote on whose video got the best results.

Here's the latest test footage - dark toners are hard!

Very impressive.
In this test the light stops moving when the coin tilts, to be more like when you have a coin in hand tilting it under your lamp at your desk. What do you think?

For when it’s just the light moving, I’d love to see if you could eliminate the glare from the slab that comes and goes by using the compass oil trick. But you probably already have a plan for dealing with that more professionally. But no matter what, you are onto something very cool, I think these are great 👍🏻

I've heard of using compass oil to get good photos of coins in scratched slabs, how would it reduce glare? I don't really see that being practical for a kiosk, especially not if I plan to automate it.
The Franklin was in a guardhouse flip, since the plastic isn't flat it's pretty much impossible to fully eliminate glare from the light source, but I did some tuning to make sure the glare wasn't over the coin, just around the edges.
The other glare I'm working on fixing is from the parts of the light fixture which are off but are partially lit by the part that's on. I need to design something like a honeycomb mesh so that the light is all directed towards the coin.
Thanks for the encouragement!

It might not work in a kiosk, just that it works wonders at preventing glare from the slabs. In the pictures below, you can see how the little “dome” of compass oil over top of the coin makes the light and glare “bend” around the coin and the reflection of the lights and glare is only visible around the periphery of the compass oil “dome”. Without the compass oil the reflections of the lights and the glare would be visible on the coin itself. Those are Ott led lights that are straight, not curved like in the reflections. Try it out sometime.

How often would you say coins are mounted in slabs at a weird angle? I'm trying to decide whether to change the design to allow the slab to be rotated so the coin is "right side up" or whether to just fix that with video editing or not at all (I really like the idea of being able to upload the files with no editing).

I feel like the videos are a little too dark in general. I don't know if it's due to the reliance on a single light source or the setup itself, but I think more light needs to be introduced into the system.
This reminds me of my process when I was first developing slab shots. With time you'll figure out the inputs that improve and you'll remove negative factors.
Here's a video I did today by hand, this is more what I think you could produce with more light.

I typically shoot 1/3 -2/3 a stop dark because it prevents the highlights from being blown out for maximum flexibility in editing, but didn't bother tweaking these clips.

I'm thinking it looks over a stop under.

Congratulations, that is very cool. And also a novel idea about taking device to coin show where people can produce videos of their own coins. You might also want to experiment with different lighting color especially to bring out features on darker toned coins.
