Added

  • A new Overlay effect family: Tessera, Fenestra, Reticle, Bezel and Astrolabe. HUD-style
    chrome — tile reveals, snapping panels, targeting crosshairs, border instrumentation, and
    a full-frame targeting-array set piece — builds accelerate them, drops strobe them —
    rendered with real transparency and locked to the beat and bar clock rather than the
    wall clock. Layer them over other Fosfora effects, or over anyone else's content in
    Resolume/OBS via Spout, Syphon or NDI with Output alpha set to Passthrough. They live
    in their own Overlay group in the effect browser.
  • Overlays that see what's beneath them: Limn and Intarsia. A new @backdrop input
    hands an effect the live composite of every layer below it — Limn traces the content's
    edges with dashes marching in time, Intarsia fills its color patches with beat-revealed
    mosaic tiles that take their colors from what they cover. Layer them over any effect or
    media layer; solo they draw nothing (there is nothing beneath to see).
  • The output can carry real transparency. Settings → Output alpha adds Auto /
    Opaque / Luma key / Passthrough: Passthrough sends the scene's actual (premultiplied)
    alpha to every sink — NDI, Spout and Syphon all transport it, so Fosfora can be keyed
    over other content in Resolume or OBS without chroma tricks. Auto keeps existing
    setups exactly as they were. See docs/alpha.md; the v4l2 virtual camera stays opaque
    (the format has no alpha).
  • Shaders can now count bars and beats. The uniform block gains bar_index and
    beat_index — monotonic counters that step exactly when bar_phase / beat_phase
    wrap, so multi-bar patterns (bar_index + bar_phase as a running bar clock) are
    expressible for the first time. ABI: PhosphorUniforms grows 432 → 448 bytes; shaders
    using the auto-injected block need no changes, hand-declared copies must append the
    two fields plus two pad slots.

Fixed

  • Beat-length scene transitions now run at the right speed. A cue with
    transition_beats set resolved its length against a normalized tempo value, making
    transitions 300× too slow — at 120 BPM a 4-beat dissolve took 10 minutes instead of
    2 seconds, silently, live and in --render-scene.
