Hi Everyone

Well, we have purchased studio basic, and have a duel kinect set-up. We have done a day of capture, but now cant seem to capture anything more because of an I/O buffer overflow error. I can record about 20 secs of video in ipi recorder then I get the overflow error ("sudden stop of recording" window).
The thing is it was working perfectly the other day, we have the exact same set-up (in fact the kinects have stayed plugged into the machine) but now I cant record anything. Nothing has changed and I have plenty of disc space, I have restarted, but to no avail.

Anyone else experienced this? any advice?, help would be great

thanks
Rob

Hi again

I think I have solved the buffer problem; I simply defragmented the drive and it works a lot better, I haven't run a full test, but it seems to work fine now with the buffer indicator staying in the green.

As workflow practice a very regular defragmentaion regime seems to be needed to keep the I/O speeds up. It surprises me as the target machine is clean and uncluttered, but a lesson has been learned.

bye for now

Nope didn't work! the buffer stays green for a while longer but it only runs for about 22secs before cutting out and getting the IO buffer error.

So whats going on? the other day it worked flawlessly, now it doesn't work at all.

Please ipi, give me a clue as to whats going on

Are you recording directly to the system drive? Unless it's an SSD, normally you should be recording to a second drive.

In my case, I use a separate SSD dedicated to iPi Recorder capturing, though a fast hard disk should work well enough if it's a secondary drive.

If you absolutely must record to a system hard disk (which generally isn't recommended,) check that there are no processes running that could interrupt Recorder's ability to write to this disk.

It seems some other software has started to take I/O bandwidth from this hard drive. As Greenlaw mentions, the dedicated HDD is preferred for video records. That is, it should not contain any files which may be accessed by other programs during recording - no program files, no swap file etc.
FYI the v2 release will feature the new record format which significantly decreases I/O bandwidth requirements.

Thanks guys

I downloaded service pack 1 (vista) and it seems the problem has sort of stopped again, and I can record for a fair amount of time. I am going to get a dedicatied drive for this now as I have been using the system drive and clearly there is a pontential problem with this.

Thanks for the help
