Downconvert Audio-Crackling

[Gary Adcock]

[Eric Sternberger] “I was under the impression that ProRes is 10 Bit! So why the issues? And what has it got to do with audio?
We recently upgraded to Control Panel 7.0. I´m not sure, but I think I havent seen this before that… “

Eric
this is one of those – I think you downloaded the driver, but forgot to update the firmware on the card.

the firmware update on the Kona 3 Card is a manual process.

Applications > Aja Utilities > Kona Firmware updater.

[Eric Sternberger] “When we switch the Video settings in FCP to 1080i 10bit we get nothing but garbage on our preview monitors. “

when you change the compression version you need to change the Video Out preset also

Question : why are you converting to UC when working with ProRes files- this is unnecessary the way ProRes was designed..

Hey Gary,

appreciate that you are still up 🙂
Just updated the firmware, it was already the 64bit Version but it was still outdated (I wasn´t aware there was a newer one)

But the problem persists: No Preview with 10bit Display-Setting, only works with 8bit…

BTW: I´m not recompressing to UC, I stay ProRes. It´s just the display-setting (in FCP)

and you are using the EASY SETUP for your flavor of video and ProRes.

this was an issue in the very first 6.0 driver, I have not seen it on the Kona 7.0 driver.

Make sure you DID NOT install the 64bit driver – correct?

The firmware now is: 2008/12/17
The footage was captured on another machine with the “HDV to ProRes”-Easy Setup.
It is 1440×1080 25fps Apple ProRes 422
On the editing-machine we used the AJA 1080i 25 ProRes 422 Easy-Setup for the project. With that we have no Preview. Only when stopped or during scrubbing we see a picture.
When we switch the display-settings to 1080i 8 bit, it works though, but we have crackeling sound…
I also uninstalled & reinstalled the 7.0 driver.
Or is the HDV-ProRes conversion the culprit? It was done with the proper easy setup though…
