Kona SD 10 Bit RGB issue

[Gary Adcock]

[Ian Cranston] ” I am unable to layback or play to the digibata using 10 bit RGB. it will play for about 4 seconds then freeze. I tried laying back with photo – jpeg and had no problems.”

your drives are not fast enough.

10bit SD needs an array to playback in real time == the data rate is over 30 mgs a second.

I have an array I forgot to mention its data rate is about 273 MB/s. I was able to playback and layback using FCP 4.5, but after I upgraded to FCP 5.1.1. it stoped. any other thoughts would be greatly appreciated.

You have a Kona SD card ??????? Then you have an old system, and probably an old drive array. I bet you have not updated the firmware of your drive array recently (like the Apple XServe RAID) – see the AJA support site for the link to the Apple Xserve RAID firmware update to resolve this issue -if you have a HUGE or Medea array, contact these companies for the update for your OS.

I am running the lastest update…any other suggestions??

[Bob Zelin]

you are running the latest update of what? I am not talking about the latest update of your MAC OS. What drive array do you have, and what firmware version is it running ?

10-bit RGB? NTSC is not an RGB format, it is YUV/Component or Composite. I don’t remember the old Easy Setups from that card, but shouldn’t there be a SMPTE NTSC 10-bit setup? I figured RGB settings were for 4:4:4 footage coming from HDCam-SR or from graphics files. If this is the case, and your sequence is also set as an RGB sequence, you are demanding more from the system than simply a SD signal. Since I can’t see your settings, I don’t know if this is relevant, but no one else in this thread has mentioned it.
