Chronos User Discussion / Re: Chronos 1.4 and 2.1 lowering bit depth to increase frame rates?

« Last post by B.H.V on December 08, 2023, 08:06:30 AM »

I've been digging into this bit depth upgrade thing. From what I've gathered, a firmware update for the 1.4 and 2.1 to boost frame rate sounds awesome, but unfortunately, it doesn't seem like it's in the cards. I wish they could pull it off, but as of now, it looks like it's a feature exclusive to the new models.

Yeah, Sanjay already got back to me and said it's not possible. : ( I'm hoping they at least can bring out an HDR or log profile for the 1.4 and 2.1 to get better highlight and shadow detail. If I recall correctly it was supposed to be planned in the early days of the 1.4 release but it was scrapped for some reason.

Getting that download time is crucial, especially for high-speed flows. I'd recommend checking the user manual or reaching out to the manufacturer directly.

Chronos User Discussion / Re: Has anyone tried this lens ?

 I haven't tried that exact lens, but I've used other Laowa lenses, and they're usually pretty solid. The f/0.95 aperture sounds like a dream for low light. If you're into fast lenses, I'd say give it a shot.

Chronos User Discussion / Re: Continuous saving of single frames

Syncing with the propeller's rpm might need some tweaking, but continuous recording at 1 fps should be doable. Check the settings, and maybe play around with the triggering options. Also, make sure your smb-share setup can handle the speed.

Chronos User Discussion / Re: OLPF filter for Chronos cameras to reduce Aliasing/Moire?

I feel your pain with the filter juggling act. Been messing with external filters on my setup too. It's a hassle swapping them out for different focal lengths, right? Your shots look solid, though. I've been eyeing the Chronos 4K12 myself, but you're right.

Software Dev / Re: Chronos V0.7.0 Full Release

« Last post by B.H.V on December 07, 2023, 10:12:15 AM »

Once we begin shipping the Chronos 4K12 (Feb 2024) and Chronos Q12 (Mar 2024), the software team will continue to make updates. We're working to make the remote control app backwards-compatible with the 1.4 and 2.1-HD, and may also add some more features at that time, so please stay tuned for February regarding potential software updates and new features.

I am experiencing similar problems as user EB described. When trying to update the camera via the internet connection I get the error that the packages cannot be authenticated and that "-y was used without --force-yes". My camera is running on version 0.7.0 Firmware version 11. I would greatly appreciate any advice on this problem.

When trying the SD card update, my camera doesnt boot properly. The fan briefly runs then the camera goes into some form of idle state, where the power button is lit but nothing else happens. Every minute or so, the power status indicator flashes in red and the camera seems to reboot, again briefly turning on the fan.

You may need to update your camera manually (writing the image to the SD card) for now as we are experiencing a few issues with our package servers at the moment. We are looking into it.

Thanks Sanjay! Is there a way the team can look at the aliasing problems I encounter with texts and specular highlights with the Chronos. I know the proper solution would be an anti-aliasing filter in front of the sensor. My workaround right now is using an anti-aliasing filter on top of the lens but it's not ideal. Appreciate all the hardwork the team is doing! : ) Also, can we get the 100,000 fps back in the official firmware for the 1.4? I'm weary of compiling the code myself.

Btw, this is an example of the aliasing I'm seeing in anothers video. Look at the 15:20 mark with the lettering on helmet. That's one of the situations where the aliasing pops up. Only way I can reduce that kind of aliasing is using anti-aliasing filters on top of the lens with my 1.4 but again it's not ideal.

UPDATE: Sanjay btw, I know in the early days of the Chronos 1.4 being released, the team was trying to see if an HDR mode or Log Profile could be implemented to maybe get better highlight and shadow detail. Can that be looked into again once you guys start looking at possible firmware updates for the older Chronos models?

Chronos User Discussion / Kronos 2.1 brand new but not showing any image on screen

« Last post by eric ritter on December 07, 2023, 06:41:46 AM »

hello everybody, i just received a kronos 2.1 hd, i booted it up and disabled the shipping mode, however the screen is just black. i removed the cover and fitted a lens to it, i can see the red mirror/ sensor  when i had the lens cap off so i know its not blocked.

i tried doing the black calibration, i did see some lines and things while it was doing that but no luck, i also changed the settings on the white balance but that also did not resolve it.

i cannot find a single thread or indication in the provided manual about this happening did i get a defective unit?

thank you for reading

eric
