I’ve been using Schlieren to study firearms. Here is an article I did. Images captured with my Chronos.

Wow that's really nice! I wish I had access to firearms around here  :-\

Nice article!

More firearm high speed. This is an Altor Pistol. It shoot 9mm and .380 with a different barrel. Due to its design the cartridge is held on the face of the bolt. And the firing pin can strike the primer causing the unsupported case to explode and rupture.

Made a new video: https://youtu.be/IVFWbvu2Npc

only a short one. I moved houses in October, so there was no time for a video this month. I hope everything get's back to normal next month :D

Here’s an interpolation test going from 240 fps to 480 fps. I tested Final Cut Pro’s Optical Flow method, Interlake’s Overcrank (similar to Twixtor), and Topaz VEAI Apollos model. The Apollo model hands down is at another level compared to the two. There are a lot of stretching/tearing and morphing artifacts in Final Cut Pro’s Optical flow and Interlake’s Overcrank method, but are almost completely absent in the Apollo model making it look more natural. Programs like Twixtor were the king of interpolation more than a decade ago, but these new interpolation methods like DAIN, RIFE, and Topaz VEAI's Apollo are taking it up a notch.  Twixtor has always had trouble with subjects passing certain objects, but Topaz VEAI handles this pretty well in this example. I'm aware Davinci has a Speed Warp option, but I don't use Davinci so not sure of the differences between that and the Apollo model. For those that want a little bit more slowmo from their Sony A7S III 240 fps or Chronos 1.4/2.1, I think the Apollo model would be a nice one to test out.

While real frames will always be better when it comes to slow-motion, It will be interesting to see how interpolation methods like these will evolve in the next five to ten years as their machine-learning algorithms better. I find that 2X interpolation is the most I would recommend doing depending on the scene, subject movement, and what frame rate you shot at (the higher the frame rate, the better the interpolation will be) as going above tends to create blurring artifacts. Also, interpolating a one-minute 1080P clip to 2X using Topaz VEAI (non-power saver mode) takes around 36 minutes to complete on my 16” M1 MAX Macbook Pro 32GB RAM system.

Test sample of magination magnets at 800 fps clashing with water and collapsing. Plan to do higher frame rates of this soon. Enhanced and Upscaled with Topaz VEAI. : )

I love that so much! I had to watch it several times, even at 800fps to follow it.

Thank you! I'm glad you liked it. I have some samples of them collapsing at even higher frame rates that I'll post in the near future! : )

@BHV how are you filming at 700fps? I thought the 1.4 can only film as low as 1057 FPS?

Yeah, you can set the fps to any fps you want. I'll shoot at a lower fps to get more light.

Yeah, I've noticed that too with very low frame rates like 20 or 30 fps.

A little frame rate comparison with blank guns this time.
Don't know why, but the picture quality with 20,000 fps looks way better than the 5 to 10k footage.

Bit hard to tell, but unless you changed some major Thing about the Light on the Last Shot, i assume you used higher a Higher Gain Setting than on the lower FPS Shots.
 .
 When used in Moderation, a bit of Gain in the right Situation (especially if otherwise the Frame would just be too dark, and you cant change that by other means) can actually give you much better overall Image Quality. At least that is true for Firmware 5.xx / 6.xx and Later on the 2.1, assume its about like that on the 1.4.
 .
 While its ofc. always best if you just have enough Light to Shoot with no Gain at all, with the Newer Firmware you at least shouldnt be afraid to try bumping the Gain a little bit if the Frame is just straight up to dark.
