AJA IO HD won't recognise SD Component input
on Apr 4, 2008 at 12:10:55 pm

Hi,

Just wondering whether anybody has run into a situation like this. I am trying to capture from a PAL VHS deck (I know, I know!) via the component analog inputs on the IO HD but, in the control panel, the input format is shown as 1080i29.97 and I can't get it to recognise the input as PAL SD. If I plug the component cable directly into the monitor, I see a perfect (albeit it nasty) PAL SD signal, but even looping this back into the IO HD inputs doesn't work. Since the VHS deck either uses the component or the composite outputs (but not both) I can't cheat a ref signal into the IO HD, but it should be OK without one, shouldn't it?

I've deleted and reinstalled the IO Drivers, checked that I have the latest firmware, and trashed the FCP prefs... but no change.

So does anybody know how to force the IO HD to recognise an SD analog input?

Thanks,
Matthew

RIght click on the frame buffer icon in the control panel and change it to 625i25.

Hi,

Yeah, that's set to 625i25 OK, but the picture is scrambled. The analog input still shows as 1080i29.97, so the IO HD seems to downconverting what it thinks is a HD signal to SD, resulting in a mess...

Checking further though, it looks like the deck outputs a progressive signal (it's a combo VHS/DVD deck) and I wonder if that is what is upsetting the IO HD.

Thanks for the tip though, I hadn't realised I'd could set the frame buffer format like that.

Let me rephrase that.

Have you opened FCP and tried this?

DO you have another signal that you can send the ioHD instead of VHS? How do oyu get a component signal out of VHS player anyway? Fancy.

Also, right click on the analog input icon and choose 625i, primary.

Hi,

Yeah, other analog input signals have worked fine in the past - it's just this damn deck being awkward.

Anyway, having realised that the deck was outputting a progressive SD source I thought that might be the problem. And indeed, changing the deck output to interlaced resulted in the IO HD immediately recognizing the analog input as 625i25.

So I'd just like to thank Toshiba for not putting the output format option in the setup menu, nor on the remote control, but via a switch hidden behind a small flap on the machine itself!

Thanks for your help though!

Matthew

Good thing you found it as I never would have guessed that.

Cheers to you.

It's a very good thing I found it as, having already spoken sternly to the deck about cooperating, the next step would have been to slap it around a bit!

[Matthew Keane] "the next step would have been to slap it around a bit!"

Yes, I know that method. At the end of it, you hope that all those switches that needed flipping have been flipped.

Glad I'm not the only one who talks to my gear.
