Chronos User Discussion / Re: Chronos 1.4 Footage Thread

Got some new footage:

https://www.youtube.com/watch?v=SPf6Pv2KeGk

It was on a German "outdoor" shooting range, so basically indoors... low light conditions. Still don't have constant light sources to illuminate the scene.

There are colored lines visible some times. I know this can happen when the memory is cold, but it was about 16 C, which I wouldn't consider cold. Is there any way to prevent this? I plan to do some more filming in early January, and don't want all of the footage to show these lines.

Also I got trouble with focusing. It seems like the adaptor ring doesn't have a good hard stop, and the backfocus needs to be set depending on the torque that was applied when mounting the lens. I still store the camera in its shipping box, because this is very well stuffed, but that means I need to take off the lens for storing.

Any ideas on how to get this fixed?

great to see someone getting some bird in flight shots!

Now that I have added my actual video link (LOL) you can check out some more.


I agree...great idea with the holosight!

I finally have a way to quickly aim and follow targets using a $40 Amazon gun sight, now I just need to find a way to quickly pull focus.

All the clips were shot with a 400mm lens (effective 1560mm) at ~f8-f11 and 6db gain on the camera.

Our forst couple of hours running around shooting anything that we could find that moved fast. LOL. Its funny, once you get to 1000 FPS its kinda hard to find something compelling to shoot.

As we are a firearms marketing firm ,expect more of that soon!

For now we wanted to get some time with the 1.4 and get sued to how it handles light and setting up shots,  working with the firmware and just general use and setup/teardown. So here is a nice relaxing slowmo vid comprised of local Prince Edward County Ontario attractions.

I bought a cheap 75ohm bnc cable on amazon and it fit and worked fine.

I also used a normally close button in my diy trigger (just used what I had laying around and didn't see this post in time) but it works fine. I just click the invert button in the trigger control panel.

Excellent footage, I see an absence of dark pixels in your video.  Did you get a second batch camera?  Everything I shoot is littered with dark pixels in the image on shadow areas.  Wondering if the batch has anything to do with it.

Also, the open source release is imminent, finally have a working build environment that doesn't have any of the NDA code in it! Hopefully within the week.

Awesome news! I'm really curious to take a look under the hood.

That mode to do exactly what you want isn't yet supported. The closest thing you can do is have the camera recording, and provide it a TTL signal to end record. You can set any desired trigger delay in frames if required. You'll need to manually select the appropriate range and then save the desired 400ms range.

Let me know if you have more questions on how to set this up.

David,

How complicated would it be to allow the user to select what resolutions we want in the drop-down menu?

Maybe we could have a few "user preset" slots in the drop-down menu? Or would this entail too many |UI changes, adding buttons etc for this revision?

That is quite easy, you could do it now manually in fact. If you put the OS SD card into a Linux system, add your resolutions, one per line, in /opt/camera/resolutions

resolutions is just a text file, the default content is:

Code: [Select]
1280x1024
1280x720
1280x512
1280x360
1280x240
1280x120
1280x96
1024x768
1024x576
800x600
800x480
640x480
640x360
640x240
640x120
640x96
