Version 6 Beta

Hi. I'm the sole UI3 developer. I have no plans to do a new interface or a major redesign of UI3. UI3 is a hobby project for me and I'm quite happy with its current state, for the most part.

And you do a Damn good job at it also. Really appreciate all your hard work. UI3 is on all my phones and monitors, and I live by it.

Hi. I had the same problem. Changing Profile from "default" to "main" solved it.

Best regards
Thanks for the response, but I'm not sure what you are referring to. Profiles in Blue Iris are user defined and I don't have a "default" or "main".
Found it, thank you!!

Today's .99 re-release includes H.265 software encoding and direct-to-wire support in UI3-306. H.265 can be enabled either in Blue Iris's streaming profiles or UI3's Streaming Quality profiles, or both.

A few notes about H.265 support.

  1. Direct-to-wire streaming may fail to play because Blue Iris sends the wrong codec string in the video metadata, causing UI3 to use the wrong video decoder. I'd expect that to be fixed in the next BI release.
  2. H.265 is not as widely supported as H.264, and so far I've found a number of browsers will say they support H.265 but then fail to actually play it.

    Here's my compatibility matrix so far for H.265 in UI3 based on my own testing:

As BP2008 has already noted (link), Ken updated the V6beta file (detected by a change in the file size).

You can direct download it here:

I've also posted it to the forum's Downloads folder as 5.9.9.99-v6betaR4
The naming mirrors Ken's version nomenclature in the changelog.pdf.

Ken did freshen the changelog PDF in this iteration (see below).

[5.9.9.99 r4] – 2025-11-15

Added
• UI3 support for H.265 including direct to disk

Changed
• Video encoder settings now use a mix of quality and bitrate with the option to favor one or the other
