dropped frames

Postby tjodork » Sat Jul 07, 2012 8:53 pm

Hi... I'm capturing video from a Sony Digital 8 camcorder via firewire to my core i7 system with an external hard drive (Seagate GoFlex 3TB drive)
I think the drive is 5400 but I can't seem to find that level of detail in windows 7.
While the drive supports USB3, my computer only supports USB2.
Over the 2 hour capture using WinDV program, I will typically have 1000 dropped frames. I tried going to my internal SATA drive and had no dropped frames.

It seems to me that if the drive can keep up most of the time, why can't it keep up all of the time?
I've ordered a USB3 - PCI card to see if that helps but curious if others can save from firewire to external USB 2 drive OR what else I could do.
Note I did plug the drive directly into the PC (in case the USB2 hub was causing a problem).
Thanks
Tim

I agree. I'm not sure a USB3 would necessary resolve your situation. The throughput to an external drive simply isn't always fast enough.

So you could capture to your hard drive and then just copy the files to your external, and it should be fast enough for editing. (This works on my Mac, but when I run my Mac in Windows mode, it doesn't -- so it's worth test driving.)

well some good news....i bought a usb3 pci card and installed last night. My first transfer to the external usb3 drive had ZERO dropped frames. Will try the next but I'm hopeful that it will be a permanent solution since copying 27GB files from internal to external each time is a pain.

(be aware it needs a floppy drive connector plugged to it for power -which my dell core i7 did not have .... I had to cut a floppy drive power cable off of an old cable and splice it to one of the sata power cables. oh one last thing....DONT ever plug a pci card into a system that still has the power cable plugged in...even when system is off...it can cause major damage as it did on my previous Dell 8400 and could have again when I stupidly did the same thing.
