Basically it looks like the entire Final Cut 3 Suite is still emulating a 2.2 gamma…even with Snow Leopard set to a 2.2 gamma. Thus all previews are way to dark. When I reset the monitor gamma to 1.8 all the previews in Final Cut, Color, and Quicktime 7 Pro with 2.2 emulation setting, then match my SDI broadcast monitor. Anyway to fix or remedy this?

Am I alone in this? I need to know if this is a known bug or something quirky on my system. If so I will wipe my workstation and re-install. Though I think this is an issue specific to the new Snow Leopard Quicktime player. It’s so subtle it may have gone unnoticed.

Well I have further news and no solution. I have wiped my system and installed both Tiger with no updates and Leopard with no updates. Both bare bone installs with basic Quicktime installs (7.1 and 7.3 respectively) had the same stuttering playback in the quicktime player. However I have discovered a strange abnormality…if played in the upper half of the screen it plays back smoothly..if played in the lower half of the screen it plays back stuttery. VLC does a much better job of playback but does kick on rare occasion in the bottom portion of the screen. Again these stutters in playback only occur most notably in the quicktime player and in the bottom half of my screen with any and all quicktime files whether downloaded from quicktime or created in any pro app or encoder. None of the Pro Apps have these problems….FinalCut, After Effects, Combustion…etc… on either the preview windows or the SDI out of the Kona 3. Windows under bootcamp has no such problems. I am at a loss as to what this problem is! Any help would be great…though I think I am alone. I’m beginning to wonder if it is the slot the video card is in and whether there are some lanes in the PCI express slot that are damaged do to changing out the video card a few times, which in turn causes stuttery playback in the lower portion of the screen. Another thought is the Kona card maybe causing some resource conflict with quicktime player? Either way my laptop plays back everything fine…which shouldn’t be the case when my workstation is a Dual Quad 3.0GHz, 9GB RAM, 760GB System Drive, 2.0TB Raid 0 Media Drive, with a Kona 3.

It is certainly not an easy thing to do and I don’t think I would use Pacifist to do it. May be best to use Carbon Copy Cloner to backup your system drive to an external just in case…then try re-installing the OS and not running any Quicktime updates to see if that resolves it. I am going to probably try it this weekend. The annoying thing is that my laptop is on the same version of Quicktime but under Tiger and does not exhibit the problem…at least as frequently. I will post as soon as I know anything. Could you post a link to the sites where you have found people with similar issues? Thanks.

Glad to hear I’m not alone! So when you try playing the files in VLC or under bootcamp they play fine? I have checked everything, multiple hardrives etc…same issue. But my laptop under tiger does not have the issue. After my currrent projects are done I may wipe my system and re-install Tiger and see what happens. I’m surprised more people havnt noticed it…it is very slight though.

Okay that was funny and embarrassing all at the same time. Yeah I think your right. I am probably seeing exactly that and that is exactly the nature of a CRT tube. I’m going to check out the same image at a studio of a friend of mine who has a similar setup to varify my craziness. Thanks for your help and I will re-post when I know my diagnoses. 🙂

Okay I have now connected an LCD monitor to the Kona via Component and there is no problem whatsoever! When sending SDI from the Kona card or S-Video from the Canopus box to the broadcast monitor you can see the same subtle horizontal line flutter (probably a pixel thick almost like a field or static line). This line pops in and out in a fraction of a second and always at varying heights. I think I can see it on my consumer TV as well..but not as pronounce. So it’s not the Kona card because it is visible through the canopus box as well. So it is surely the Broadcast monitor, possibly a minute artifact of the tube’s gun? I’m now not sure if it is a problem with the monitor or a problem in that my eyes are to good. Barely anyone can see it! And if someone does they only see it once. If you sit at a normal viewing distance, instead of the 1 ft distance at my desk, it’s not noticeable. Does anyone have a 15″ JVC Broadcast monitor with SDI card and can sit really close and look at high contrast text on black and tell me if you see the same? In normal video footage, it is very difficult to see and has to be sitting still and again a high contrast difference area (White object with dark backing). I’m wondering if I’m to much of a perfectionist and just have an eagle eye and only recently noticed this possible natural side effect of a CRT tube based broadcast monitor?

It is not visible on the computer’s LCD screen at all, only on the output from the Kona on the broadcast monitor. Every piece of software that can utilize the kona output to the broadcast monitor has the same effect in the external monitor with any and all footage and formats(After Effects, Final Cut, Combustion, Color). I hooked up an external Canopus box that gets fed via FireWire and sends an S-video connection to the same broadcast monitor, and it shows the same effect. That makes me think its the monitor and not the Kona. I’m going to buy some bnc cables this afternoon and wire up an HD LCD via component from the Kona to make sure. I will re-post when I know more.

Thanks for the response.This happens in normal video though as well. Same effect, a horizontal flutter that looks like a line of static almost from right to left that flashes and distorts anything under it for that fraction of a second it flashes and then dissapears to flash in another area at a different horizontal height. Very difficult to see on video unless your close to the monitor and in high contrast areas…darkness seems to lesson the effect. I hope it’s as simple as a field issue and natural occurence of a field based tube monitor…but the fact that it’s not specific to text and it occurs regardless of placement on the screen and it distorts or flutters the video beneath it and it jumps around, I don’t think it is. Could it be an electrical disturbance? The SDI cable sits on two DVI cables behind my computer monitors before emerging on the other side to go into the monitor? I’m going to go by some component cables today and run them from the Kona3 to a LCD monitor to see if it is the Kona’s problem or the monitor. However that would only prove that the component outs of the Kona are fine and that it’s either the SDI outs or the Broadcast monitor. Any other suggestions or help would be greatly appreciated.
