Kona 3 as a DDR?
I am trying to use Mac Desktop + Kona 3 as a single/dual link HD-SDI player/recoder, since this setup is much cheaper than HDCAM/HDCAM-SR decks and even quality is better. Then, I confronted an issue: How to control Final Cut Pro or Kona TV to be slaved to the other machine?
I tried a bit, but failed. I had to use it as a non-controllable device. Any thoughts?

The real issue is it more practical on location a portable SRW-1 HDCAM SR machine and the answer is no except if in the studio.
Try lugging your mac, hard drives etc out to the beach on the sand and see if that setup will be ideal.
Cheap comes with a tradeoff in the harsh world of location shooting.

I know, I know… I am talking about a less mobile solution, like as a playing server kind or used in telecine suite.
For acquisition, I hope that single or combined 2.5 inch SATA hard drive catridges storing 2K resolution wavelet codec compressed file would do the magic in near future. Considering people use DVCPRO HD 720p24, which is highly (DCT-based) compressed 8 bit media, as an acquisition format for many purpose right now, 1080p24 10 bit (linear) wavelet codec media will not be too shoddy for various uses. This could be more compact solution than HDCAM SR, if wavelet encoding unit is implemented successfully.
Still, as a not-so-mobile player/recorder solution, Kona 3 equipped Mac desktop is attractive in cost.

Wow, somebody did the homework. Thank you for the information!!!

have you tried the Kona TV app? its free and it is used quite a bit as a playout server.

Funny you should ask……we have been doing this for years with the AJA products. Konas, Xenas or OEM boards, they are all the same to us.
Designing and developing a robust DDR has been lots of work but very rewarding (the people we get to work with). The RS422 alone will keep you chasing your tail (you would not think this to be the case). But a DDR, like a deck must connect to anything and be controlled by anything without flaw and again run like a rock. With the help of many studios worldwide we have done this with RaveHD. The entire code base (including the I/O driver) is our own so making something work efficiently is easy.
Now onto portable.
This has been the question for several years. Understanding that we are entirely uncompressed, the question or rather problem of getting it down to a portable unit has been a goal. Again a robust portable solution. HD can run off several drives, so slapping a few drives in a MAC or PC might seem like a good idea (and will most of the time work) but remember your needing to replace that SR deck that doesn’t work most of the time, it works all the time.
Sooooo having said this. We are currently involved with a very high-end project with multiple cameras and a technical team that is as cutting edge as they come. The combined effort is allowing us to tackle this portability issue head on and at the same time allowing us to introduce features such as native DNx and OMF support as well as removeable 2:3 on the fly to name a few.
Taking an off the shelf software package will only get you about 80% of the way for what you need, we all know it’s the last 20% that is the hardest.
Please don’t hesitate to drop me a line I would be more than happy to answer your questions. Watch for news on the on-set project later this year.

Thank you for commenting on current status of RaveHD. I have known your product for years.
If I need serious and reliable DDR functions, I would have been contacted your company. For the specific purpose I need this time, the Kona 3 equipped Mac has also some benefits over hard-core DDR’s, such as your RaveHD or other Cineform codec based one. And the cost itself is sometimes not an issue, but sometimes not-so-big difference could be critical.
You are very correct about off-the-shelf software capability. When I need your experty, I will remember that you are there. Thank you.
