Thanks, I will have to bite the bullet and order it.  I find that the easy detachment is good because that way you can't leave it in place if on a wrist lanyard so the Loupe Sun Screen Burn problem is avoided.

Chronos User Discussion / 5" LCDVF adapted to the Chronos?

« on: April 09, 2021, 03:27:42 AM »

Looking at options to allow run and gun with the camera I came across this 5" LCD viewfinder for the Blackmagic PCC 4k and 6k that may fit the Chronos.

https://www.bhphotovideo.com/c/product/1547095-REG/kinotehnik_lcdvfbm5_viewfinder_for_blackmagic_pocket.html

Wondering if the dimensions will fit the Chronos as it looks a bit too wide and if anyone has experience with it? 

I did find an old thread with a Grid 5 viewfinder that had some success but doesn't look like an optimal solution as it needs modifications. https://forum.krontech.ca/index.php?topic=134.msg1123#msg1123

I believe this accessory if done well could be a killer part of the Chronos kit.

After my limited testing, it is clear the banding has been reduced a whole lot. It will still show up in the shadows and under exposed areas severely (Shows up as red and cyan vertical bands in shadows mostly).  However, given enough light and taking care to overexpose a bit it is fairly well reduced.   I was able to get Topaz Video Enhance AI to almost completely eliminate the shadow vertical banding after processing which really saved the day. 

I can't attest to the DR loss since I went straight to v6 for my testing but it will be good to try to preserve more of it.   All in all very stable release, no issues with saving multiple clips for about 4hrs.  I was also pleasantly surprised by the good quality h.264 output with lots of detail from the 2.1 camera which is in my view an order of magnitude better than what the 1.4 was able to achieve.  Of course, shooting DNG RAW remains unmatched.

I am so glad to see this improvement, I will install the patch and test it out. This really changes things as the banding was really problematic in my initial testing.   Thank you greatly!

Hi sanjay,

loving the update so far, zooming is very useful and an excellent addition.  Are there any plans to get the UI to be able to switch to top and down for 720p record mode (I am on the 1.4)  The screen real estate is eaten by the UI on the left or right but it would be extremely cool if we got to see the image preview in the full width of the screen which will be considerably larger.  The UI thread from DDR (which I am including the image) had this exact layout in testing. Just wondering if it's coming or scrapped?   
Great work on 0.5 team!

some chronos 2.1 fun to promote a fine dining restaurant that's now doing luxury home delivery.  Made primarily for Instagram. @atticamelbourne @lunecroissant @colinpagephoto

Excellent work and very clean, definitely some of the best out there with the 2.1!

I can see column banding becomes much more visible and still apparent at 0dB. My guess is that more calibration will help with that like it did on the 1.4

Excellent first tests, looks to be a really clean image that should perform well even at higher dB gain.  It is already crushing the best I have seen on my 1.4

« on: January 05, 2020, 05:58:17 PM »

So I finally got around to test this version after all the end of year madness, and have to report that it works very well.  I had an initial scare when I updated and all that was shown was a color chart with a lower right noise snow screen and nothing happened.   I promptly forced reboot and all was normal, with interface loading.

Black calibration worked fine and I find that it does a better job than before "Could be my eyes deceiving but could be better banding elimination algo" Or the changelog feature: (Automatic ADC calibration during black calibration, which should reduce column banding across a wider temperature range.)

The most annoying bug from the RC2 which was peaking making the camera crawl on an external HDMI monitor is gone and it works perfectly with no slow down or lock-up.   I recorded about 7 clips and no lockups which were a common thing in the last RC. I will have to test for longer standby and rec times but so far very stable.

I can't wait for the new standard UI to start rolling out to see a larger screen preview along with the info.  Great work team!

Cheers!

I used the latest beta RC2 and the lag on peaking with an external monitor is gone but now the camera hangs on displaying video at random junctures.  The interface somewhat works but the exposure bar and live feed are gone or frozen. Only fix is getting the camera to shut down and start back up.  Happened about 7 times in a 4hr period.  No idea what is causing it, I tried with and without HDMI plugged in and behaved the same way.   

The frame selector bar on play tries to adjust but it's pegged at 0 and frame 2 even when you try to scroll higher or lower. No image is displayed either.

I believe the current design you showed is excellent and a vast improvement that gives the frame much needed space. Very RED like and useful without digging  into menus. Would love to have it soon including the latest peaking fix so I can use my monitor with it again.

Interesting, thanks for the testing the camera is getting better every day!

Found another small problem.

In Firmware 0.3.1 the first frame of RAW DNGs was completely white and now Frame #1 is still full white and now new bug Frame #2 is the last frame of the recorded area instead of the second frame in the sequence as it should be. This is happening for all saved sequences. It is a minor inconvenience as I have to delete both 1,2 from the sequence before processing.

I did notice saving is much faster on SD cards for some reason on 0.3.2 RC1, I am getting 4.5-4.8fps instead of 3.8 as a maximum before.  Very welcome change!

Thanks so much, looking forward to the peaking patch, I miss the feature big-time since my monitor peaking is not as accurate as the one you guys have been able top include in-camera!
