Can’t capture more than 20 sec
Hi everybody hopefully somebody can give me a little help with this. I’ve just installed a Kona 3 into my G5 quad and for some reason I can’t seem to capture any more than about 20 seconds at a time before the capture fails saying that there were dropped frames detected. If I try to capture clips shorter than 20 seconds everything is fine but larger clips will not work regardless of if they are attempted with the “Capture Clip” feature or logging them first and attempting a batch capture.
I’m trying to capture Digibeta via ‘SDI In 1’ on my Kona with embedded audio. My A/V settings are
Sequence Preset: AJA Kona3: 525 29.97 10 Bit
Capture Preset: AJA Kona3: 525 29.97 10 Bit
Device Control: AJA Kona3: 29.97 Sony VTR A
Video Playback: AJA Kona 525i29.97 10 Bit (720 x 486)
Audio Playback: AJA Kona
I’ve got all new cables and I’ve tried a few different ones just to be sure. Deck control is via 9pin and Blackburst is feeding the VTR before looping into the Kona3 breakout box where it is terminated by a 75ohm terminator.
The machine is a G5 Quad on 10.4.2, 6.5GB ram, FCP is 5.0.4 and I just installed the new drivers recommended by the AJA support site. I’m trying to digitize to an xServe Raid 5.6TB connected directly to my G5 via 2gig PCIe card from Apple. That’s all of the details I can think of if I’ve missed anything that could help to solve things please let me know.
Thanks in advance for any and all help.
Jeff

Is your array formatted correctly? We had a similar post just recently and it was the formatting of the array that was incorrect and there was a 2GB limit being hit on the drive. So FCP would stop digitizing when it hit the 2GB limit. Check that your array is properly formatted.

To be honest it was configured for me so I’m just now getting into the Admin and might not know just what to look for. It is striped RAID 50 and under the performance tab both controllers are set as follows.
Use Controller Write Cache = yes (checked)
Allow Host Cache Flushing = yes
Use Drive Write Cache = yes
Use Steady Streaming Mode = no (unchecked)
Read Prefetch = 8 Stripes (512 KB/disk)
The Fibre Channel Tab has speed and topology set to automatic for both controllers.
Does this all look kosher? Do I need to check elsewhere as well?

Turn off “Allow Host Cache Flushing”

I just got caught with that EXACT SAME THING !!!!!! Rudy Van Kol at AJA told me about this, and I posted a detailed thing about this (Along with the Apple notes on it) on the XSan forum on Cow. I sat there (back and forth) for a WEEK trying to figure out what it was, and it was just the Cache Flushing setting.
