/beats?path= returns bpm, a phase-locked beat grid, downbeats (4/4) and an honest confidence, using only stdlib + ffmpeg: decode to PCM, log-energy onset flux, harmonic-enhanced autocorrelation with an octave check, comb phase search, weighted LS grid refit. 4-min track analyses in ~0.5s, cached after. Audio in/out now honoured at mux in both scene renders and film beds via one resolve_audio() path. Found en route: on this ffmpeg build the obvious atrim/asetpts + amix/apad chain yields an aac stream with ZERO samples, rc=0, no warning - trim moved to the input side; and the test helper would have passed on that empty stream, so it now refuses to answer on a window that decodes nothing. Tempo bias fixed after orchestrator ground-truth check: decoding at 22050 discarded the HF transient, and since the attack's HF share grew across a file the surviving LF onset landed progressively later - a per-beat-varying lateness that reads as tempo error. BEAT_SR now 44100/512 (same 86fps envelope). Second bug found by sweeping: harmonics outside the lag table counted as zero and the parabola was fitted on a slope, so 118 BPM read 114.79. Verified vs independent ground truth: 120.030 vs 120.003 true, 128.020 vs 128.004; worst offset from the true grid 6.0/10.1ms over the whole file (was 45/52ms). Tests now assert whole-file DRIFT, not average BPM, incl. a 200s track and hftick.wav (16kHz tick over a 60Hz body) which pins BEAT_SR. 18 groups green.

SCENEGOD — machinima director's sandbox
Drop characters, Mixamo clips, and photo backdrops onto a 3D stage; keyframe transforms, cameras (with cuts), and lights on a timeline; render an mp4 with muxed audio. The Movies / Source Filmmaker energy on the GODVERSE stack.
Run
.venv/bin/uvicorn scenegod.server:app --port 8020
# → http://127.0.0.1:8020
Assets live in assets/{characters,animations,props,backdrops,audio}/
(plain folders, scanned live — files sharing dir+stem are one entry; a
same-stem image becomes the thumbnail). Scenes save to scenes/*.json,
renders to renders/ (reaped after 48h).
What works (v1)
- GLB/FBX/OBJ characters & props; spec-gloss (Character Creator) GLBs are converted on load. Image backdrops: flat plane, corner, or 360 dome.
- Mixamo-style clip retarget onto any mixamorig-named skeleton, client-side (world-space rotation-delta bake, ported from MESHGOD rigroom).
- Timeline: transform + param keyframes with easing, clip blocks with
trim/loop/crossfade, multiple cameras + cut list, keyframable sun/ambient,
audio tracks (Web Audio preview; server-side ffmpeg mux in the final mp4),
viseme/morph track with Rhubarb JSON import (
GET /rhubarb?path=if the rhubarb binary is installed). - Render: draft webm (MediaRecorder) or deterministic PNG-sequence → ffmpeg h264 (+aac) mp4 at any resolution.
