v0.2.0
0347cc3

The Insta360 movement upgrade. v0.1.x reframed via static stock moves (orbit at
constant speed, dolly-zoom linear); v0.2 makes camera motion cinematic and
music-aware.

Added — Tier A: eased motion primitives

Every move (orbit, tilt_reveal, dolly_zoom, crowd_reveal) now uses
cosine ease-in-out instead of linear ramps. Two new combined-motion primitives:

  • counter_motion: yaw turns one direction while pitch oscillates and h_fov
    breathes. Three orthogonal motions from one cheap source.
  • dolly_with_drift: push-in plus slow yaw drift. Subject-lock effect.

Added — Tier B: music-driven moves

  • bpm_sync_orbit: yaw rotates exactly N bars per full turn, BPM-locked.
  • kick_pulse_fov: h_fov pumps at BPM frequency for subliminal beat sync.
  • drop_impact: 4-phase preset (freeze → whip → dolly-zoom → hold) for
    the moment of impact.
  • build_tension: quadratic-ease h_fov tightening into the drop.
  • breakdown_drift: ultra-slow yaw + slow pitch tilt for breakdowns.

Added — Tier D: stochastic move pools

  • lib/selector.pick_move_for_event: weighted RNG pick, intensity-biased,
    with 3-pick avoid-repeat window. Same set rendered twice → different cuts.
  • presets/styles/{aggressive,clean,signature}.json: weight overrides.
    aggressive ships drop_impact every drop + whip-pans dominating; clean is
    cinematic and slow; signature is the balanced default.
  • presets/references/{anyma,fisher,rinse}.json: artist-style packs.
  • --style, --reference, --seed CLI flags on dj-edit edl.

Fixed — codex round 1 + 2 (CRITICAL)

  • TI is normalized [0,1] in sendcmd, NOT seconds. Rewrote every move's
    math to use T (absolute seconds) instead of bare TI. The v0.1 expressions
    like 45*TI meant "45 degrees TOTAL" — not "45 deg/sec" as designed.
  • Commas inside sendcmd expressions break parsing (verified in ffmpeg
    n8.1.1). Replaced piecewise if(lt(x,a),b,c) with multi-line time-windowed
    commands (each command on its own line, no nested if). Replaced pow(T,2)
    with T*T.
  • Render cache only hashed EDL JSON, not cmd file contents. Tweaking a
    move generator while EDL JSON stayed byte-identical → cache served stale
    video. Now hashes EDL plus every referenced .cmd file's content.
  • _generate_move_cmd returned a relative cmd path. Broke when render.sh
    was invoked from a different cwd. Now returns .resolve() absolute path.
  • target_yaw or 60.0 made explicit target_yaw=0.0 impossible. Now uses
    target_yaw is None check.
  • load_pool_overrides silently fell back to defaults on --style typo.
    Now warns to stderr (with the resolved file path) for missing pack files,
    malformed JSON, or pack entries referencing unknown move names.
  • Intensity not clamped. Negative or >1 event intensities could produce
    zero or negative weights in pool selection. Clamped to [0, 1].

Added — Tests + CI hardening

  • 131 pytest tests (up from 41 in v0.1.x). Includes:
    • 21 lib/moves invariant tests (no-pow, no-if, no-commas, uses-T)
    • 14 selector pool-selection tests (weight bias, avoid-repeat, packs load)
    • 60 shipped-preset hygiene tests (12 presets × 5 invariants) — this
      test set automatically catches the codex round 1 regression class (where
      presets weren't regenerated after a lib rewrite).
  • Full quickstart --demo end-to-end smoke verified: drop detected, set_9x16
    • set_16x9 + highlight + per-drop clip all produced in ~8 seconds.

Verified end-to-end

All 12 generated .cmd files render through real ffmpeg n8.1.1 sendcmd (orbit,
drop-impact, build-tension, kick-pulse-fov tested with rgbtestsrc input;
frames at t=0 and t=1s have different md5sums → motion confirmed).
