AJA Kona LH DV Playback – Distorted + Digital Noise

[Walter Biscardi]

Definitely don’t see any issues of this sort here with our Kona 2 and Kona 3 systems. Either capturing a source as DV or simply playing back DV material through the Konas.

What is the quality of the original Beta material?

Do you have a black burst generator?

I haven’t seen noise, but this week I noticed distortion in the picture after an up-rez recapture: Offline DV –> DVCPRO50 via LH.

For some reason some of the clips had the wrong aspect. After looking at the Motion tab, all I did was reset the aspect to 0 under the distortion option.

Other than that, captures and playback have been fine. As suggested, try trashing some preferences, maybe uninstall/reinstall Kona drivers.

Good Luck

the Kona LH does not do upconvert – you had to have done this is software which is why the aspect was off.

Correct sir, this was a recapture. I took the clips offline and recap’d with the DV50 codec. This is when some of the clips were distorted.

Might have something to do with the timeline and less to do with AJA hardware.

Hi All,

Thanks for all the replies.
This Kona LH has a PAL black burst reference input.
I’m going to trash the Kona pref files to see if its make a difference, as adviced by Kona Support.

Cheers,
Ben
