Need help setting up Sub Streams

[fahl]

Looked at Wiki but cant make head or tail of it?
Help Please
Running BI 5.3.1.6x64
Have 6 onvif cameras,all working fine but a bit choppy.
Been trying to set up Sub Streams but totaly lost
Cameras are
2X Igeek
C6F0SgZ3N0P6L2

2x Tenvis
JPT3815W-HD

1x IGEEK

1X Tenvis?
TH692
Sub stream page cameras attached
First is Igeek cameras

You need to match FPS and key frame interval (try 15 for each) and then setup the substreams within Blue Iris.

Go to the camera settings and provide a screenshot of what the Video>Configure screen. You need to add stuff to the substream if Blue Iris didn't auto populate it:

That is unnecessary. The FPS and key frame interval almost never need to match. This is an old workaround for video corruption found in some cameras circa 2014, yet I see this advice still given out for all manner of unrelated problems. For most cameras today, having the keyframe interval match the FPS just needlessly reduces video compression efficiency.

A key frame interval anywhere between 1x and 4x the frame rate is perfectly acceptable. Most cameras I've dealt with set it by default to 2x the FPS, and that is just fine.

Why do you need sub streams for a 720P camera and a 1080P camera? I believe the purpose of Sub-streams in BI are meant to be used with 4MP and up for motion detection, to reduce the high load of CPU processing.

The Tevis is a 1 FPS, it will be choppy. On the lgeek, where is the bit rate specifed.

I will be having a play with this today.
Btw Igeek are the choppy ones but only on Blur Iris,not on tenvisSearch or any other of the many other softwares i tried last night,All the tenvis ones are fine.

Won’t you have issues with motion detection using such a low res substream? I use at min a 720p substream else I’ve found events get missed unless your doing generic motion detection

^That is weird - why isn't it showing the substream parameter input - which version are you running?
