Describer Workbench 0.8.1 makes Public meeting mode (city and council meeting videos) write fewer, better cues.

What is new:

  • The model is told to skip small body moves (a nod, a hand on the table).
  • A filter drops cues that only say a small move or "nothing changed".
  • Each cue gets a second look: the model checks it against the picture and drops it if it is not true.
  • When a slide cue and a cue about a person overlap, the slide cue is kept.
  • Only meeting events (votes, speaker changes, slides, on-screen text) may pause the video.
  • A blank row from the model no longer breaks a whole chunk.
  • A vote found from the captions is not dropped by the second look.

Quality on 13 test videos (105 cues graded by hand, model gemma4:12b):

Measure 0.8.0 0.8.1 Target
Correct 29.5 % 67.6 % 60 % or more
Wrong or made up 15.4 % 3.8 % 5 % or less
Trivial (true, but adds nothing) 36.5 % 10.5 % 15 % or less
Spoken in a gap, or a pause for a meeting event 45 % in a gap 100 % 70 % or more
Extra length added (meetings) +6.0 s per minute +1.6 s per minute under 15 s per minute

The "spoken" target now counts a cue that pauses the video for a meeting event. A pause cue never talks over a speaker.

Known limits:

  • The model can still call something a vote when there is none. On one test video it said "An audience member raises a hand." and no hand was up.
  • Results change from run to run on the same video.
  • Some videos get very few cues (2 in 5 minutes on one test video).
  • AI output is a draft. Check every draft before you export.

Downloads:

  • Windows x64 portable ZIP: signed as Scott Converse with Azure Trusted Signing, timestamped, and checked with Authenticode and signtool.
  • macOS Apple Silicon DMG: ad-hoc integrity signature only. No Apple publisher certificate or notarization.
  • Linux x64 DEB and portable archive: unsigned.
  • unix-media-sources-arm64.tar.gz: source code for the media tools inside the Mac app.
  • Python wheel, source package and offline documentation.

The Mac and Linux files were added after the Windows release. They come from commit 7a2c402 (PR 58). That commit only fixes the version number in the Mac and Linux packaging scripts. The app code is the same as the Windows build.
