ioHD SD Codecs

Posted by Toby Risk on October 7, 2007 at 12:14 am

Hi
I am sure this one has been asked before but I can’t find the answers, I am tossing up between
buying the V3HD and the ioHD.

What Standard Definition codecs does the IOHD support?

Is the proress 422 codec a full 1920 x 1080 frame, it looks as if the V3HD only handles 1440 x 1080?

Thanks

Toby

IoHD will allow capture to any SD codec or uncompressed.

ProRes is full raster so 1080i would be 1920×1080, 720p would be 1280×720. The V3HD aspect ratio for HD is bound to DVCProHD so that is why it is not full raster.

to my knowlege, there is no DVCProHD Codec available for the I/O HD, and the I/O HD will CERTAINLY not do uncompressed HD.
The selection in the I/O HD menus will be for ProRes422 and ProRes422HQ only, for HD (all SD should be available – but what the hell do I know – I would love to see an advanced pdf manual).

With Uncompressed I was only talking about SD.

I was told at NAB in the AJA booth that DVCProHD would also be a capture option for HD. But I was also told they would be shipping in July 🙂

Bob, do you think we will need a black burst with this? 🙂 Just joking I think I know your answer to that.

With a fast enough machine, you will be able to both ingest and output DVCProHD with the ioHD. Yes, I know this isn’t in the documentation anywhere. Just trust me.

Any word yet when it will ship? I keep getting e-mails from AJA and they keep saying any day now.

I have the official answer –
“any day now”. Alternate answer – “very soon”.

Do I get a cookie ?

Thanks for the replies folks, the only other question is up to the AJA distribution people.

Yours waiting patiently

Taken from the AJA post on the ioHD shipping.

[AJA Sales Department] “- DVCProHD, 720 and 1080 formats, ingest and playout (CPU-based)
“

Just for the sake of follow through.

The IoHd supports capture in all FCP supported capture codecs for Standard Definition,
those include Uncompressed 8 bit and 10bit, DV50, DV25.
