Downconvert on ingest

[Jeremy Garchow]

Have you chosen the 10-bit 625i preset in FCP?

Hi,

You simply apply a down-convert in the KONA Control Panel to the input you wish to downconvert. Jeremy is right, then of course you would set FCP with a KONA Easy Set-up for SD.

Thank you,

That’s the bit I’m having problems with! The Format menu (where I assume the down-convert’s applied) is greyed out. Is this not how I do it?

Definitely using a SD timeline, thanks.

Thanks for your help,

Tom

Select the FCP easy setup to AJA Kona 3 10 bit 625i or whatever it is, then open up your Kona Control panel. On the format tab, set your primary to 625i, and your secondary to 1080i/25. The control panel should detect that your input is 1080i and set a downconvert and whatever SDI input is active (1 or 2). The video input should say 1080i/25 and the frame buffer should say 625i.

Hmmm … just tried it on a second machine, being fed material directly from a JH3, and it worked like a charm. Precisely how I thought it was going to work: I was able to change formats instead of the drop-down menu being greyed out.

Will try again when the other machine becomes free. It was being fed by a Miranda HDV converter, but that shouldn’t make any difference should it? Still a valid 1080i stream going in.

Thanks for your help,

Tom

I don’t have any experience with the Miranda. What I would do is take the Miranda over to the machine that you got it to work with the JH3. If you can get that machine to work with the MIranda, then I’d say you have a bad/problematic Kona 3 card in the original computer. If you can’t get the Miranda to work on the second computer, then there’s something funky with the Miranda.

I have GOT to be missing something here. You want to downconvert on ingest, and you are using a JH-3. The JH-3 has DOWNCONVERTERS built into the VTR. Simply take the SDI out, or the Analog component out, or the analog composite out, and go into your AJA product (for Kona 3, take the SDI out, not the HD-SDI out from the VTR). Select the correct easy setup for SDI 525, and away you go – no control panel stuff !!!!!

Yeah – I was using the JH3 to test the workflow! Well aware it’s got a downconverter in – quite a good one, too. Some clients of ours bought in some HDV (eurgh) footage and our HD-Connect box was already being used. So we had to hire in a Miranda, which doesn’t have a downconverter and, well, that’s where we’re coming from.

Still haven’t been able to test it yet with the Miranda. Will post back if I have any more issues.

Thanks to everyone for their help,

Tom
