Any ideas what is causing this?

It seems to do it on my i5 laptop with 4gb ram windows 7... Freshly formatted with nothing on it too. It doesn't seem to do it on my beast i5 overclocked machine



I would say maybe the laptop can't handle the video, but it's really not THAT demanding. I have 3 1080p cameras running, 1 720 and 1 480

Seems to do it with all of them.

Direct write to disc btw
 
The happens with direct to disc so you need to tweak settings to make it go away...camera properties> video >configure change the receive buffer to 10mb.
Make sure your iframes match your frames per second. If that does not work try messing with cbr vs vbr... or increase your bitrate and see if there is any change..

I've tried both constant and variable. It wasn't doing this before.... very random.

match your set your i-frames to 15...if that doesnt improve things try constant bit rate instead of the variable.
 
i actually had it at 15. I just changed it to 15 because you said to lower it... I also had it at constant too
 
If it happens on one computer and not the other, why are we focusing on nvr/camera settings?
 
Could you delete your webrec file in programs and let the nvr reinstall new active x onto that computer? Could you watch cpu usage in task manager while the cameras are displaying?
 
This was kens response with respect to a cam-it user who emailed him about the issue.
"Easy fix ... this results from setting the FPS too low. With D2D, you need to set the FPS >= what is actually being received ... you cannot "drop" any frames otherwise there will be incomplete frames in the recording but not live. Ken"
I believe he is saying to adjust the frame rate in blue iris to higher than the incoming frame rate...the auto function may be screwing things up.
 
I'm bringing an old topic back up, but with a new computer, sitll having some issues. now I need to figure it out. so we're back in action. See the new thread...

Ok, let's see if this worked. I have the camera at 15, and I'll do 20 for BI. it was 15 before (so same)

edit: nope didn't help. What did help was going from D2D to re encode, but that's not something I really need as I have time stamps already, and it just uses up extra CPU
