Aja Kona vs BlackMagic Decklink HD
on Oct 11, 2007 at 7:58:14 pm

I'm comparing these two card lines:

http://www.blackmagic-design.com/products/hd/

http://www.aja.com/html/products_macintosh_kona_LHe.html


Would be destined for use with Final Cut Pro 6 in a MacPro tower.

Will still be doing mostly SD work, but preparing for future SD work. Making promos and commericals, some with a lot of compositing.

Wondering what the pro's and con's are from people out there using them. Does support for ProRes or other codecs differ at all with these cards? Do any of them have hardware-assisted chroma/luma keying?

Have you searched this forum first before posting? This issue has been pretty much discussed to death on this forum.

I know that this is supposed to be a happy, friendly forum, that is designed just for this type of question. But you would figure that if someone needed to research this information, they would spend 15 or 20 minutes, glancing thru the last few months of posts on the AJA and Blackmagic forum, to observe other users questions, and answers, and see what type of products these really are (in addition to the AJA and Blackmagic website). This is EXACTLY what I do when I look at http://www.reduser.net to research details on the RED camera, and its development.

"BUT I AM BUSY - CANT YOU JUST ANSWER ME". Well, sure. There are lots of people on these forums that would love to sell you their old Discreet edit, or Aurora Pipe card, or Pinnacle CineWave card. Maybe you should consider the DPS Velocity, or Edius, or maybe even Sony Vegas.

Want a real answer - how about reading this forum, and the Blackmagic forum (spend 30 minutes on each one). Then read the AJA website on the Kona 3 and I/O HD, and read the Blackmagic website on the Eclipse, Multibridge, and Decklink HD Extreme. Then come back and ask some questions, and I will be happy to answer them for you.

One thing i noticed to my surprise with the decklink line of cards and multibridge it seems that you cannot configure the two SDI outs differently as you can with aja cards, one SDI out can be feeding an HD monitor the other can feed an SD monitor (downconverted) or in my case an SD scope for now.

Hope this helps, BTW I read these post's thoroughly and I haven't seen mention of this, I hope some tells me I missing something because the Decklink and Multibridge line is very strong otherwise

The Blackmagic Eclipse is in fact a fine product. It thrills me that it is the same price at the I/O HD, because most of the people asking questions like this, see one product priced $200 less than the other, and their only real concern is "gee, if I get brand X, I can save 200 bucks".

The eclipse seems to be an incredible product so I guess at that price range you can configure each SDI out differently? can anyone confirm this?
-- one as HD and the other as SD

Thanks

I was very disappointed to see that Blackmagic does not have the Eclipse manual up on their website yet, even though the product is released. As you know, Bob, most of Florida uses AJA, so you don't see many people racing to order the Eclipse, even though it appears to be a fine product. Don't assume, however, that the Eclipse has the ability to seperate it's outputs like the AJA Kona and I/O HD (although it's possible - I just don't know !).

Well I've kept my head low for now to avoid it getting choppped off :-P

But I'm glad to see I at least sparked some discussion amongst others. And from that, I've formed a specific question now..

I'm wondering if y'all can nail down what 'support for ProRes' actually entails for the Kona and Decklink cards. My guess would be that it just means you can capture in ProRes via the card providing your Mac's processors are up to the task of performing the compression on the fly. I am assuming that these cards don't take on the burden of compression with their chips in any way. If I am right, am I further correct that units like the Aja ioHD completely take the load off the processor when dealing with ProRes?

Yes, this is my understanding of the process.

[Fongaboo] "If I am right, am I further correct that units like the Aja ioHD completely take the load off the processor when dealing with ProRes?"

Yes, this is my understanding of how the Io HD works. I'll actually have one here shortly to test out and then I'll have a better handle on exactly how it works and how it compares to the Konas.

I have experience with both AJA and Blackmagic products, but only with AJA on the HD side. I have owned a Decklink SP card, an HD Link, and an Intensity HDMI card. I have had problems with Decklink drivers for the SP, with intermittent display issues with the Intensity (could be an HDMI handshake problem, but a problem nonetheless), and I returned the HD Link after discovering that the unit did not do a good job of displaying SD video, only HD. Not that SD should look great on an HD LCD monitor, but it looked really bad. And the marketing on Blackmagic's website made it sound like a solution for both, but it was not.

I have never been disappointed with an AJA product. I can always get someone on the phone if I have an issue. When I did have a component fail in my IO, a replacement was shipped next day air so I had almost no downtime.

Lots of people use Blackmagic products and seem to like them. They may work just great for you. They have not for me. At the least I would recommend that you get information on their products firsthand from someone who uses them daily in the same situation as yours, rather than just reading their website.
