I7-9700F No Quick Sync

[Ripdis85]

I have a Dell Optiplex 7070
I7-9700F processor
32GB DDR4
7 Amcrest 4K Cameras

The 9700F does not support quick sync. Does quick sync really make a difference on the CPU usage?
Recording would be done direct to disc and utilizing sub streams.

Any thoughts?

Definitely makes a difference in CPU utilization, I believe the 9700F has no integrated GPU, therefore no Quick Sync

I stopped using Quick Sync earlier this year because I think it was causing stability issues and Blue Iris was automatically disabling it on random cameras once in a while anyway. Sub streams more than make up for the lack of hardware acceleration.

Aren’t the sub streams intended to use lesser bandwidth though?

If anything the bandwidth, network utilization, will go up a bit since you may have to actually enable and "broadcast" the sub stream along with the main stream. What it does do is reduce the bandwidth through the processor, less video to process in the sub stream, and drop CPU utilization significantly.

What if the end user is recording 24/7 on Blue Iris and doesn't have any other piece hardware to process the the main stream video? Wouldn't CPU utilization go up significantly? In this case, would it be ideal to disable the sub stream then?

The CPU doesn't process the raw video other than encoding it into .bvr. That is a very low overhead operation. If you're using sub streams and HA, try shutting off HA and see how little the CPU utilization goes up.

CPU utilization will go up significantly without substreams.

Hardware acceleration is separate and the end user can still watch video without a graphics card or intel quicksync.

My computer cannot use HA with H265, but I can watch H265 just fine, just cannot use Hardware Acceleration with H265...
