[Michael Aranyshev] “How would one tell? I have a bunch of Alexa footage in ProRes 4444. What is a quick way to tell whether it is RGB or YCbCr?”
I used a spectrum analyzer from Tektronix, it is neither cheap nor quick.
It is my understanding that issue was only with the specific build on the cameras I was testing and that later release versions support both formats. I do not have confirmation from Arri (August is holiday time in Europe) .
I am going to go out on limb and assume that if you are shooting as Rec 709 you will be working with YCbCr materials since you have defined that material by working in the Video Rec, while if you are recording LogC you should be working with RGB content on the SxS cards.

It’s not just about a good chair, it’s also proper posture, correct keyboard position( lower than your armrests) monitor position and room lighting, all of which affect your ability to work lengthy periods of time.

[Steve Godun] “It should also be noted that this issue arises even if there’s NOTHING connected to the Kona3 card”
that makes no sense whatsoever- and if it is happening within the mac and has nothing to do with input/output.
What decks and connections are you using?
Are all the machines on the same versions of QT/ OS/ FCP.Does content still appear affected with no card in the machine?
Does a clean install of the systems and apps still show an issue.Have you tried running the AJA conflict catcher app? its in the aja utilities folder
“I don’t mean to sound ungrateful. This is just bothering the heck out of me”
you are also not giving us any kind of specifics to go on- I personally do not believe all of the machines are exactly the same- something is different and you need to stop and re-evaluate.
If there is no problem after a CLEAN INSTALL of the just the OS and the Kona Hardware- then you have some thing to go back to as a baseline.

Sorry, I meant to say what are your not using FCP or Aja’s VTR exchange app to capture.
What does the control panel say? Is it matched to your inputs?gary adcock

First off.
What app are you recording too? Why are you using FCP or aja’s VTR exchange app.on the mac or Machina on windows?
Secondly you do not say what you are trying to record over which type of connection. the Kona 3 is a digital only card, is your source hdsdi? Are you sure?gary adcock

Hen you need to present to them in real terms how much time it saves you. Corporate manpower is on of the biggest expenses.
Look at it this way, all post becomes simpler because you are now handling footage from a single source no matter which camera is used, that means no more overnight renders with HDV footage.
Studio usage includes automatic tape digitizing with certain deck/ tape combinations- thereby allowing you to
setup the KiPro to digitize camera master tapes, with
timecode into ProRes ( over hdsdi-)gary adcock

[Jeremy Garchow] “I’d call AJA support.”
yeah, I second that one.

[Tim Pendergrass] “Anyone having problems powering up the ki pro? I hold it down, hit it fast and still it takes several tries to get it to power up”
nope
are you on Battery or AC?
have you updated the firmware recently?

[Chris Wiggles] “Now you are simply attacking my credibility,”
Like you are not attacking my credibility?
By your own admission you are a newbie, both here on the Cow and as a video user?“entirely ignoring the camera specifications, framegrabs, and example clips that I referenced for you and for anyone else to test and examine entirely on their own without my (or your) credibility at all relevant.”
Correct- why would I take an unknown entity such as a first time poster and admitted newbie and trust my livelyhood on your word?
Better yet why would I trust anyone else’s random files posted on the internet?
Where are YOUR files?
Where are YOUR Test results?“By what method did you ascertain this? Did you record in 1080p60 mode? Did you know how to accomplish this with this camera?”
You obviously ignored my link to the Tektronix signal testing link I posted last time.
I test all signal path processing using industry standard diagnostic and analytic HARDWARE from both Leader Instruments (LV 5800, LV 5750 and a Phabix signal tester on loan) and various Tektronix units based on SMPTE specs for baseband video. I also used Aja’s Hi53G and HA53G converters to handle the HDMI x HDSDI conversion process, so that I was able to pass the baseband video signal out of the camera, just like I would with any other camera being tested for signal analysis.
“I have shot small amounts of 1080p60 with it myself.”
ROTFLMAO
so a camera newbie also? https://magazine.creativecow.net/article/camera-and-lens-roundupYour naiveté regarding how and why real cameras do what they do does little belay the fact that I am happy that this camera worked for you.
This camera did not pass what I required of it, but please be my guest to continue to call me a liar when you have naught to show, nor much if experience with this camera or for that matter any other camera that might actually be able to shoot 1080p60 as the specification is defined and I will assume that the over $1000 per day rental on the professional level cameras that shoot 60p are beyond your budget.

[Chris Wiggles] “However, your claim that consumer cameras simply inherently cannot support 1080p60 is bizarre, particularly given that such cameras do exist and are readily purchasable. “
as I stated here:
https://forums.creativecow.net/readpost/8/1095041
if you do not understand the nature of what the signal was engineered to do, how can you expect to understand the whether what you are working with is correct or not?“I don’t disagree with your criticisms of this camera that you made above in terms of its performance issues, but keep in mind it is simply a ~$1K consumer camcorder. “
Yes I understand that and even given such a low price point, I still tested the camera using industry standard tools for testing and analysis.
https://www.tek.com/Measurement/App_Notes/indexes/video_audio/registration/?lc=EN&PRODUCT=&returnUrl=ct=TI&cs=pri&ci=2210&lc=ENYou, by your own admission, tell us that you are new to the video world, I on the other hand am not.
I have never said that this camera did not take acceptable images- I stated that my testing showed that the camera was not outputting what SMPTE decides is a proper 60p signal, and that the signal i tested on an early camera model was a 60i signal that was line doubled- a common occurrence with the earlier HDMI consumer specifications, not the later 1.3a and 1.4 HDMI specs.
I did not trust my eyes, apples antiquated quicktime player or even FCP to handle that footage, just like I doctor I ran tests understanding what the baseline is, using tools designed to provide critical analysis of baseband video.
Since I have worked with virtually all of the current professional camera systems that can properly produce a recording at 1080 60p, my knowledge and client base force me to be more critical than others. I do not rely on ANY camera mfg’s specs for anything more than an assumption that it is correct, but I also know that specs written for a camera that sells for $1000 are not exactly written or even proofed by engineers, but more likely by some marketing intern.
I test a great many cameras and lenses, this camera did not meet my criteria in producing a proper signal that could be recorded according to the 1080p60 specifications for the work that I do, and as I told the last poster here- I am glad that this camera works for you and your needs, it is not up to my standards and expectations for what 1080p60 is supposed to be.
