I will call you guys as soon as we ship the DLT on this project. I simply didn’t have time to figure this out for this project but I’m very curious to figure out what the issue is. Thanks.

I would do what Bob Zelin suggested and get somebody in your shop or call AJA Tech Support to find out what is going on. Downconvert is a very straightforward thing with everthing happening in the card. In 2 years of running the K2 I’ve never seen anything like that no matter what the originated footage.

Does anyone in the LA area have a system set up with a HD/SD switchable broadcast monitor and a Kona3 I could bring our DVCPROHD file over to and check it out? Let me know, and what you’d charge me. Thanks. If you have a Digibeta deck all the better so I can compare our output from Sunset Digital with what the Kona can do. Thanks.

I wonder if the problems you describe have anything to do with your viewing monitor. Depending on how it was calibrated and the model of the monitor used you will get vastly different results compared to what Sunset is using in their bays with the aid and support of a full time engineering staff.

HDV is 4:2:0 so I would expect to see some bad chroma artifacts after multiple generations.

I’m going to jump in the fray backing both Walter and Bob,

I have not seen any issues with the Down-convert from any of the Kona Boards, Walter and I both were amazed at the quality of the NAB 2K demo being shown at HD and NTSC rez with virtually no loss.

you are not trying to go to PAL are you???
you have checked your Kona Control Panel to make sure everything is correct?
did you check the cabling? ( and change them just to be safe)

The footage was shot DVCPROHD straight to disk from the HDSDI out of the XLH1. No HDV involved…
