Kona 2 problem – blue pixel dust-like interference
I’m getting intermittent blue pixels in my SDI video out. There is one every one to five seconds. They never appear in the same place twice.
This has happened before when watching 8bit footage when the easy Setup was on 10bit but changing it back to 8bit fixed it then.
I’m working in AJA KONA 2- NTSC 8 Bit UNCOMPRESSED, 29.97. I tried both SDI video outs. I have blackburst going into the Kona2. This happens on Apple Uncompressed & Blackmagic codec clips (Rendered by FCP & not rendered) & on footage captured with the Kona2, DecklinkHD & After Effects rendered Quicktimes. On playback & on “Edit to Tape”.
Well it seems to have started working correctly for now, even though I didn’t really change any settings. This is a problem we are running into more & more. Anyone else experiencing it?

Happened to me, too. Turned out it was a faulty card.

Are you sure these pixels are being laid back to tape? I’ve noticed that there are some odd blue and green pixels that appear during playback on my LCD monitor(s) (especially on HDV footage), but they don’t get laid back to tape. These aren’t the old typical dancing pixels with an LCD.
I thought it might be an issue with FCP, however I’m intrigued that this could be a Kona 2 card issue. Especially since I think it’s still under warranty…

Hi there,
Also having this problem…
The blue pixels appear and disappear randomly all over the screen – only really noticeable when the sceen is mainly black, but if they’re going to get layed off onto tape, then we’re in trouble. Haven’t got a recordable deck in yet, so can’t check this.
Luckily the specks don’t appear to be on the actual footage – a frame-by-frame analysis shows that thay’re never in the same place on the same frame. They’ll even disappear when parked on a still image.
I’ve played a HD tape directly into the monitor (great big Sony multiformat thing), and the specks aren’t there, so the problem must be coming from the card. Yes?
I’ve noticed that they don’t appear when playing a slug or matte generated in FCP – only on captured footage.
I’ve checked my Easy Setup, changed it back and forwards, but the specks are still hanging around.
Anyone managed to fix this? …or are we looking at a dodgy card here?
Many thanks,
Al
