I agree with the OP, and I’m not convinced the 4:4:4 colorspace is to blame. I don’t accept the projector explanation either. When comparing a DVD movie on a progressive screen to video shot 24p (either 720 or 1080) with the EX1, to me there is a huge difference in motion stutter and flicker. This has nothing to do with pulldown or projectors, as both sources are being displayed in native 24p. For some reason, the film source appears to have smooth motion, even in 24p, while the EX1 footage simply looks jittery. I’m glad I’m not the only one to notice this. I would like to figure this out because there are many advantages to 24p in regards to making a DVD, but so far the results I have seen simply don’t cut it.

I am having this same exact issue, except I am doing a multi-clip edit with two sources shot in 720p60 and one source shot standard def, 29.97i. Is After Effects the only program capable of creating an interlaced scan file from 60p, or are there others? I don’t have AE and it seems kinda expensive to buy it simply for that function.

What about 720p footage shot at 60p? Shouldn’t it be possible to recreate standard NTSC interlaced video from that? If not, can somebody please explain why? I’m currently trying to figure out how to interlace footage shot with the EX-1 at 60p in order to use it together with standard-def footage.

As I said, turning off the external reference had NO EFFECT. That was the first thing I tried. If it was something that easily fixed I would not have bothered posting the problem. I’m not being defensive…I just don’t appreciate being patronized. If you treat everybody like you know more than them you’re bound to get some people upset. My question was whether the card needed an external reference to capture, and that question was answered, before you bothered posting. Your post served no purpose other than to try to show off your “knowledge” of the situation. And by the way…the control panel reference options aren’t “internal” and “external”. The options are “Free Run” (the card itself generates house sync), “Ref In” (the card uses the composite reference feed for genlock timing) and “Video In” (the card uses the actual video input to reference its genlock timing). These options affect PLAYBACK ONLY. When capturing, the card can either be locked to an external reference or not. Generating a house sync when there is nothing else to time to that sync is utterly useless. None of the options in the Control tab of the control panel affect capturing whatsoever. At least, this is how it is with the latest Kona LHe control panel software. It is possible that the software is different for other models…I couldn’t say. My point is, stop acting like you know it all when you really don’t understand the situation yourself. I will stop now as I really don’t want to get into a flame war. This is all beside the point anyway as the issue has been resolved.

Um, I’m not stupid…I had the control panel open while I was working with the problem. Switching the reference option didn’t have any effect, and as far as I can tell it only matters for output anyway. The only way to fix it was to restart the computer. Please refrain from condescending comments when you don’t have all the information.

I think I figured it out. The genlock issue was showing up in the canvas as well, but I think it had to do with the fact that I had previously genlocked the card to the DVCAM deck. After turning the computer off and back on again the problem seemed to clear up. Apparently the card has to reset after it receives a reference before it will work without one. At last that’s as much as I could tell.

I’m new to these forums and have just purchased and installed a Kona LHe, to be used for a variety of applications. I am using a similar setup as the OP with a slightly different problem. I’m confident that the Z1 is set up correctly, but when i try to capture video via the component cables it looks as if the Kona card is expecting a genlock reference that isn’t there. In other words, there is an image but it contains no genlock. Am I doing something wrong here? Does the card require a composite feed into the genlock input in order to accept an HD component signal? BTW, I’m well aware of the advantages of having a reference while capturing, but as this is impossible with the Z1 (as far as I know) I’m stuck without it. And simply getting a deck isn’t an option at the moment for me…due to both budget and time restraints. I was under the impression that the Z1 could be hooked directly up to the card, but if this is not the case I need to know. Thanks!
