i installed the BI software on a server, but i noticed a large quality loss (i notice it when i zoom) when i try to watch the live or the recorded video with ui3
how i can watch a single camera at full quality/raw ?

Blue Iris - Web Site (Preview Cameras blurry)

When I login to Blue Iris over the website, the live preview camera feeds are choppy/blurry. If I click on the camera it's got a good image. Is there a way to improve the live preview?

that topic was talking about the multiview camera, i was talking on a single camera, the quality is "good" but not like it should be

  • On the single camera that you're not pleased with, have you set up the main stream and the sub stream in the camera's webGUI?
  • Can you post a screenshot of that cam in Blue Iris' "camera settings" => "Video" tab => "configuration" that shows the URLs for the 2 streams?
  • In UI3 what is the selected "streaming quality" on the left side?

UI3's streaming profiles with "VBR" in the name are configured to use relatively low quality and low bit rate limit in order to work more efficiently over slow or data-capped networks.

If you have the bandwidth to spare, the non-VBR profiles such as "2160p" are much higher quality.
Specifically the 2160p profile defines that the stream should use:
  • Quality: 50 (you will be tempted to set quality to 100 but doing so will not help meaningfully, and may cause stability problems)
  • Max Width: 3840
  • Max Height: 2160
  • Max Bit Rate (Kbps): 8192

You can edit this and other profiles via UI3's main menu > Streaming Profiles:

There's no way I know of where the camera will transmit raw uncompressed video. If you don't need to see the full frame, ROI can sometimes make a huge difference, as well as running the highest possible bitrate of course.

Yeah ROI (region of interest) can do amazing work when the camera is otherwise too limited by its own bit rate or simply has a badly tuned encoder. The problem is of course, for all the quality gains in the region of interest, you lose at least as much quality from everywhere else.
