However beware that hardware acceleration can cause a number of problems such as ghosting in the video or reduced stability of Blue Iris. If your Intel CPU is 6th-generation (such as i5-6500) or newer, then you can use hardware acceleration for H.265 streams as well since around mid-April 2020 (beginning Blue Iris 5.2.5 or so). Hardware accelerated decodingIf your CPU supports Intel® Quick Sync Video, then you can use hardware acceleration in Blue Iris to reduce CPU and energy usage with any camera streaming H.264. In case you need to reduce Blue Iris's CPU usage further, there are some other things you can do. Note: If you use sub streams, your CPU usage will likely be low enough that you can ignore this section and run whatever frame rates you want. This max rate setting is supposed to auto-adjust itself upward as necessary, but higher values of this setting directly impact your server's memory usage in a huge way, so don't let it be much higher than the camera's true frame rate. rate" option in camera properties on the Video tab to your camera's actual streaming frame rate, or just barely above. For best efficiency, it is recommended to use frame rates of 15 FPS or lower, as beyond about 15 FPS there is little meaningful improvement in video smoothness compared to the additional processing costs.Īlso set Blue Iris's "Max. This setting is configured individually for each camera in the camera's web interface. Each frame requires CPU time to process, so the lower the frame rates, the better. In most situations, this is a lot more than you need. Most cameras have a default frame rate around 25 or 30 FPS.
