Ultrastudio Pro Dropped frames

Hello,

I recently bought an Ultrastudio Pro and connected it to a PC but i'm getting some dropouts... even while not recording; i've got all drivers updated... Even the renesas USB 3.0 (Driver 2.1.36.0 - Firmware 3028)

i'm using the Ultrastudio to record a feed from a Panasonic AV-HS450N, and start editing immediatly after, on Premiere CS5.5.

i'm recording 1080i / 50 - DVCproHD

This is my setup:

Motherboard: Gigabyte GA-X58A-UD5 Rev. 2.0
Processor: I7 960 - 3.2Ghz
RAM: Kingston 2x 4GB DDR3 1333 CL9
Graphic: VGA Asus ENGTX550 Ti DC (on lane x16 gen2)
HDD (system): WD 1TB 64Mb - 6GB/s
OS: Win7 Pro 64-bit
HDD (record) - Stardom RAID 0

I'm really out of ideas / solutions...

What could it be?

Hey PAlex

By dropout are we talking about dropped frames? Capture and playback ... using which software/utility? Have you checked your scratch disk/media drive speed? Do you have an alternative drive you can test with? And if/when you take the UltraStudio Pro out of the equation then all ok?

Sorry, I don't have a USP I can test with but these seemed like some pertinent questions.

Best of luck
Andy

Hello Andy,

Yes, we're talking about dropped frames...

I tried with Media Express (latest version) and with Premiere Capture... it happens even when the system is idle...

I tried with two RAID 0; one from Stardom and other from G-Tech and both are able to record 1080i50 - DVCProHD codec...

i can't take the Ultrastudio out because i don't have any other Capture device with SDI In...

Thanks

Paul
