Software Dev / Re: Chronos V0.4.0 Beta - Debian and Networking

Stupid question: Can you keep various versions each on their own uSD card and just swap them around? For example to use the 40k FPS mode in version V0.3.2 then swap the card for V0.4.0 to try the various new features?
Yes, this is possible, just like swapping SD cards in a Raspberry Pi ;D

I've done this but had issues saving to an SD card that had older footage from version 0.3.2 on it. After I tried the new software version and had issues I reinserted the old card, but I couldn't save to the SD storage card. It would tell me "file already exists, rename and try again" when I tried to save. Removing the SD card with the old video files on it and replacing with a blank USB key solved the problem.

I was referring to swapping the firmware SD card. But even then, having a file storage SD card formatted by each firmware version and marked as such and swapped when the firmware SD card is swapped wouldnít be a big deal. That said, if there are firmware version/hardware limitations for example having network capable firmware results in sacrificing speed or some other feature it would be advantageous to have multiple firmware versions so if you need a specific feature you swap in the version with that feature while giving up another. Speed for networking, or whatever. It would allow the user to taylor the application as needed and add versatility to the hardware. And simplify things too by keeping menus simple and not trying to cram everything into one all encompassing version.

Unfortunately, we have decided to remove the 100kpfs feature because of the artifacts at high framerates (around 50kpfs or higher). Starting in the next update, it will no longer be available for the 1.4 or 2.1. The max framerate will be back to 40kpfs for the Chronos 1.4, and 24kpfs for the Chronos 2.1.


Couldnít it be left in place as an experimental firmware version with appropriate caveats? I can understand not shipping new production units it. But it would be cool to experiment with something on the fringes especially if itís just a matter of swapping the uSD card and rebooting.

Flying Bee @ 5899 fps  https://youtu.be/FsSZM7V7td4

Can you give us more details on that lens configuration? The canon video is impressive!

Thank you! For this videos I used a Sigma 18-35mm F1,8 DC HSM  for Nikon with a Photodiox (incl. manual aperture) adapter.

What are your thoughts on the Topaz Labs software that youíre using and specifically how it applies to slo-mo work? Have you processed/cleaned up video without upscaling it?

Hello again,

because nobody can visit me during easter time, I just shot all my painted easter eggs :D
And I also tried out the 100,000k+ Framerate of the 1.4. Very impressive! I will do a more detailed video of that in the future.

How are you getting the 100,000 FPS frame rate? More info on the lens & lighting?

Hi there,

I use the 4.0 Beta version. This will allow for nearly 110.000 fps.

Lens: Samyang 35 mm 1.4 with a cmount Canon EF Adapter
Not that cheap at all :'D 500Ä

Lights: 2 x godox sl 150W

:)

You can See the whole rig in my 40.000 fps Video in the beginning. Nothing changed that much since this day :)

Thanks! I wasnít aware that the V4 firmware had that capability since someone made a post re. the loss of 40k/s option. What is the resolution at 100k/S? (Waiting on a 1.4 or Iíd know the answer)

NVM I found it in the 2.1 thread 320x32

Thanks all for the kind replies. I clearly have a lot to learn so I'll keep reading and watching.

These are what I was referring to. The are 120W and 6000K color temp so that probably isnít the best for CRI. 5000K I would think would be better. My application is primarily going to be machine and mechanical diagnostics which the monochrome model would be best suited for but I donít want to limit myself so Iím planning to go with color.

Chronos User Discussion / Lighting question
« on: April 04, 2020, 10:47:23 PM »
Been reading the various threads on lighting and the discussion on the LED modules. I was wondering if  anyone has tried using those LED light bars that they sell for vehicles? They are obviously 12V. I have two 24Ē versions mounted on my tractors roll bar and they are blinding bright. I paid something like $55 for the pair. Iím thinking of lighting a scene where you might normally use one or more of the halogen work lights.

I didnít want to start a new thread so Iím asking here. Iím considering the purchase of the 1.4 and trying to decide between monochrome and color. Ideally it would be great to have both. The main application will be for technical & R&D work and I know the monochrome is generally recommended for that application. Iíve watched a great number of videos from this thread and Iíve only seen one side by side comparison between color & mono back on page 8 and it was of flames. Iím curious if anyone has done a side by side preferably of something detailed, mechanical in a frame rate of 8000fps or higher and had a video that they could share, Iím mainly interested in comparing the detail resolution. Or if anyone has a collection of mono videos. I understand the difference in light requirements etc.  Thanks.
