This is just the result of you using too small of a group frame size. Adjust it here.Is it possible to avoid this aliasing on the scaled video in UI3? If I view a single camera full size it doesn't have the jagged edges. Does UI Settings have a preference I can adjust for anti-aliasing? It seems like Blue Iris Options > Other > Advanced > Scaling doesn't appear to affect this in UI3. These cams are 4K 3840x2160. Thanks!
But when viewing just a single camera (instead of all cameras) it looks good:
bp2008, thank you! That fixed it and it looks great now. I set the group frame size to match my camera's native resolution. Performance is still good, too.
A few notes about this. The CPU % readout in the Blue Iris console is refreshed kind of slowly and the one in UI3 is refreshed even more slowly. Better to look in Task Manager.
That isn't a particularly fast CPU, so it is not surprising to me that encoding a 3 megapixel @ 10 FPS group stream would be a little taxing. What I would suggest for you is to try the ultrafast preset to see how much of a difference that makes, and consider reducing the group resolution from 2048 x 1536 to something lower, perhaps 1440 x 1080 which is the same aspect ratio but half as many pixels. Also while it won't affect CPU usage, the Maximum Keyframe Interval in Streaming 0 profile is best set to 300 (which is the maximum that field will take).
The VideoPostProc option for hardware acceleration may be hurting performance more than it helps. Try the Intel option without VideoPostProc. Remember to restart Blue Iris after changing this so it takes effect.
If you specifically experience the delayed video warning when mousing over clips or alerts, then I suggest you turn off the "Clip Preview Animations" feature in UI Settings > General Settings. This feature can be really expensive for Blue Iris's CPU usage because it requires Blue Iris to do a lot of extra seeking and video decoding.
I don't know of any other setting. This looks like a Blue Iris issue. I will mention it to the developer and see if he thinks the resolution of the group cycle stream should be the same as the group stream.I it possible to get a higher resolution with the cycle group? What settings do I need to change?
I have a 32" TV showing this signal, so a little bit better quality would be nice.
Blue Iris encodes frames from all the cameras into one. I've tried the approach of streaming from all cameras separately in the past, but performance is terrible compared to the composite stream.bp2008, When a group of 10 cameras is being shown, are there 10 separate streams being sent to UI3? Or is the entire group being encoded by BlueIris as a single video stream?
