Iteration 61 — re-skin strength sweep — Lean On str=0.65 (reads as gouache painting)

AI Visualizer — Wed, 17 Jun 2026 01:47:56 GMT

Strength-sweep arm of the Session 36 re-skin pivot. Same frozen Opus storyboard as iter59; ONLY img2img strength changed (0.40->0.65). Reads as a gouache painting; dominant figure+pose still inherited from source, busy multi-dancer composition collapses to lead. See scripts/spike_reskin.py.

Iteration 60 — re-skin strength sweep — Lean On str=0.55 (brass-honeycomb asserts, bg->bokeh)

AI Visualizer — Wed, 17 Jun 2026 01:47:54 GMT

Strength-sweep arm of the Session 36 re-skin pivot. Same frozen Opus storyboard as iter59; ONLY img2img strength changed (0.40->0.55). Aesthetic asserts strongly; secondary/background subjects begin dissolving. See scripts/spike_reskin.py.

Iteration 59 — Session 36 pivot — re-skin existing video (Lean On, 16s, str=0.40)

AI Visualizer — Wed, 17 Jun 2026 00:55:06 GMT

Session 36 pivot spike: instead of synthesizing motion, re-stylize an EXISTING music video. Pipeline: yt-dlp segment of Major Lazer & DJ Snake 'Lean On' (16s) -> frame extract -> Gemma4 vision keyframe captions (pve197) -> librosa -> Opus aesthetic anchors (per-movement, not per-scene composition) -> SDXL Turbo img2img every frame, init=source frame, fixed master seed for temporal coherence. No compositor, no latent chain, no RIFE (source is 25fps). Premise validated: composition/blocking/motion inherited verbatim; strength=0.40 re-skin is subtle (next arm: strength sweep). scripts/spike_reskin.py

Iteration 58 — kick-dust-cn-skip-scene0

AI Visualizer — Wed, 22 Apr 2026 19:04:00 GMT

A/B vs iter57 (https://tube.sethpc.xyz/videos/watch/08fcb8c1-4fc8-4500-9bbf-45fec2c6c33f). ONLY delta: --cn-skip-first-scene. Addresses Seth's iter56/57 observation that simplicity-gravitation was worst 'especially in the first scene.' Structural asymmetry: scene 0 has no B-injection (scene_idx>0 check) and no complement-prev (no prev_B yet), so CN operated unopposed there. Now CN is skipped on scene 0 only — runs as plain img2img chain like the pre-CN path — and engages from scene 1 onward, where α=0.5 + complement-prev provide content-variety counterweights. Expectation: scene 0 should read like the pre-CN iterations (content variety preserved); scenes 1+ behave like iter57 (spatial lock with content-pull counterweight). Kick Dust CN sweep: iter55 (cn=0.5/α=0.3)=10.84 → iter56 (cn=0.3/α=0.3)=11.24 → iter57 (cn=0.5/α=0.5)=12.46 'better not solved' → iter58 (cn=0.5/α=0.5/skip-scene0)=12.67 Mbps. Storyboard cached, same 15 scene prompts.

Iteration 57 — kick-dust-alpha05cn05-B

AI Visualizer — Wed, 22 Apr 2026 18:27:22 GMT

Option B of the AB sequence — A/B vs iter55 (https://tube.sethpc.xyz/videos/watch/2816d507-8c8e-4e90-a13d-1558228f9131) and iter56 (https://tube.sethpc.xyz/videos/watch/17116a7c-7146-48c4-bd4f-9bd37bd8abcf). Delta from iter55: --b-inject-alpha 0.3 → 0.5 (restores S32 sweet spot). Keeps cn=0.5. Tests whether stronger B-injection content pull counteracts CN's simplification in scenes 1+. Known limitation (per Seth's iter56 verdict): scene 0 has no B-injection and no complement-prev counterweight, so CN dominates there regardless of α — iter57 won't fix first-scene simplicity-gravitation. Kick Dust CN sweep: iter55 (cn=0.5/α=0.3)=10.84 → iter56 (cn=0.3/α=0.3)=11.24 → iter57 (cn=0.5/α=0.5)=12.46 Mbps. Storyboard cached.

Iteration 56 — kick-dust-cn03-A

AI Visualizer — Wed, 22 Apr 2026 17:59:13 GMT

A/B vs iter55 (https://tube.sethpc.xyz/videos/watch/2816d507-8c8e-4e90-a13d-1558228f9131). ONLY delta: --controlnet-scale 0.5 → 0.3. Lighter CN touch. Seth's iter55 verdict: 'not really better — structure more consistent but simplicity-gravitation present at scene start.' Hypothesis: lower CN scale preserves some spatial lock without forcing simplification. Kick Dust sweep (CN-enabled): iter55 (cn=0.5/α=0.3)=10.84 → iter56 (cn=0.3/α=0.3)=11.24 Mbps. Option A of the AB sequence; iter57 will test cn=0.5+α=0.5 (B). Storyboard cached.

Iteration 55 — kick-dust-controlnet-AB

AI Visualizer — Wed, 22 Apr 2026 17:21:34 GMT

First full-track render under the S34+ControlNet merge. A/B vs iter52 (https://tube.sethpc.xyz/videos/watch/9d0f1d6b-9032-43b7-81d4-e720917ba7d0). ONLY delta: --controlnet-scale 0.5. Everything else matches iter52: Kick Dust 175.8 BPM, 1fpb (base_fps=2.930, RIFE 20×, effective 58.6fps), α=0.3, complement-prev, max_strength=0.5, per-frame seed. Architecture: pre-computed 15 scene anchor depths via Depth Anything v2 (from fresh txt2img of each scene prompt), linearly blended per-frame between consecutive scene anchors based on scene progress, fed to StableDiffusionXLControlNetImg2ImgPipeline (Turbo UNet + ControlNet-depth-sdxl-1.0, conditioning_scale=0.5). Tests the core hypothesis: ControlNet-depth spatial anchor + current content-pull (α=0.3 + complement-prev + per-frame seed for Euler anti-convergence) fixes the spatial-churn issue seed-lock couldn't (iter53/54 both convergent). Seth's S30 iter15 verdict at cn_scale=0.5 was 'too locked/surface-repaint' — that was under plain linear_scene without α/complement-prev content pull. Kick Dust sweep: iter50 (no-cn, 0.7/0.5)=18.15 → iter51 (0.5/0.5)=12.88 → iter52 (0.5/0.3)=10.99 → iter53 (per-scene seed)=15.37 convergent → iter54 (chunk5 seed)=22.97 convergent-cycling → iter55 (cn 0.5)=10.84 Mbps. Bitrate nearly matches iter52 — CN is structure-locking but total frame complexity is similar. Verdict needed: does spatial churn finally feel resolved?

Iteration 54 — kick-dust-seedchunk5-AB

AI Visualizer — Wed, 22 Apr 2026 15:32:39 GMT

Middle-ground seed test — A/B vs iter52 (per-frame, https://tube.sethpc.xyz/videos/watch/9d0f1d6b-9032-43b7-81d4-e720917ba7d0) and iter53 (per-scene lock, https://tube.sethpc.xyz/videos/watch/eeda1c1a-1757-4bb7-897a-efbc8df212d8 — severely convergent per Seth). ONLY delta vs iter52: --seed-chunk 5 (5-frame blocks share a seed). At 1fpb=2.93fps, 5-frame blocks = ~1.7s stability islands with sharp seed-flip transitions at chunk boundaries. Kick Dust sweep now: iter50 (per-frame/0.7/0.5)=18.15 → iter51 (per-frame/0.5/0.5)=12.88 → iter52 (per-frame/0.5/0.3)=10.99 → iter53 (per-scene/0.5/0.3)=15.37 convergent → iter54 (chunk5/0.5/0.3)=22.97 Mbps. iter54 is highest bitrate seen on this track — chunked seed creates sharp boundary transitions every 1.7s. Storyboard cached, scene prompts identical to iter50-53.

Iteration 53 — kick-dust-seedlock-AB

AI Visualizer — Wed, 22 Apr 2026 15:03:08 GMT

A/B vs iter52 (https://tube.sethpc.xyz/videos/watch/9d0f1d6b-9032-43b7-81d4-e720917ba7d0). ONLY delta: --seed-chunk 0 (per-scene seed lock). Every frame in a scene shares one seed — Euler Ancestral per-step noise becomes deterministic across frames within a scene, locking spatial layout. Attacks spatial churn directly per Seth's iter52 verdict: 'less semantic change but spatial change still an issue, gens less wild.' Risk: attractor convergence (S28) — but α=0.3 + complement-prev provide content counter-pull. Kick Dust sweep now: iter50 (0.7/0.5/per-frame)=18.15 → iter51 (0.5/0.5/per-frame)=12.88 → iter52 (0.5/0.3/per-frame)=10.99 → iter53 (0.5/0.3/per-scene)=15.37 Mbps. Bitrate jumped back up with seed lock — possibly because RIFE has fewer smooth paths between more-distinct keyframes. Next: iter54 with seed-chunk=5 (middle ground).

Iteration 52 — kick-dust-alpha-AB

AI Visualizer — Wed, 22 Apr 2026 14:23:29 GMT

A/B against iter51 (https://tube.sethpc.xyz/videos/watch/0be13ebd-41b4-43cf-900b-066dc1424c8e). ONLY delta: --b-inject-alpha 0.5 → 0.3. Everything else matches iter51: Kick Dust 175.8 BPM, 1fpb (base_fps=2.930, RIFE 20×), max_strength=0.5, linear_scene schedule, complement-prev ON. Storyboard cached — scene prompts IDENTICAL to iter50/51. Hypothesis: lower B-injection blend magnitude slows per-scene content shift, should preserve structure longer across the track. Bitrate 10.99 Mbps (vs iter51 12.88, iter50 18.15 — monotonic decrease). Kick Dust max_str/alpha sweep: iter50 (0.7/0.5)=18.15 → iter51 (0.5/0.5)=12.88 → iter52 (0.5/0.3)=10.99 Mbps. Seth's feedback on iter50/51: 'practically the same, structure doesn't maintain.' Seth confirmed complement-prev is helping, so keeping it on. If iter52 finally shows improved structural continuity, α is the real lever. If still 'too drastic,' the problem is upstream (scene count, seed variation).

Iteration 51 — kick-dust-maxstr-AB

AI Visualizer — Wed, 22 Apr 2026 13:10:48 GMT

Clean A/B against iter50 (https://tube.sethpc.xyz/videos/watch/c83e8101-1397-46ab-b4b7-7de9a08aa188). ONLY delta: max_strength 0.7 → 0.5 (full revert to S33 default). Everything else matches iter50: Kick Dust 175.8 BPM, base_fps=2.930 (1fpb), RIFE 20×, effective 58.6fps, linear_scene α=0.5, complement-prev ON. Storyboard cached from iter50 (same cache fix used), scene prompts IDENTICAL. 424 SDXL frames, 380 B-injections — structural match. Bitrate 12.88 Mbps vs iter50's 18.15 Mbps (-29%) — empirical fingerprint that max_str=0.5 produces less per-frame semantic change, which was Seth's goal (iter50's max_str=0.7 verdict: 'reactive to music, but transitions drastic and change fast'). Kick Dust's 5.43× on-beat ratio means clean beats fire the kick often, amplifying max_str's effect. Hypothesis: 0.5 should tame the 'drastic transitions' while preserving beat reactivity via BEAT_BOOST=0.2 additive.

Iteration 50 — kick-dust-176BPM-1fpb

AI Visualizer — Wed, 22 Apr 2026 12:21:16 GMT

First render on Homemade Spaceship — Kick Dust (144.8s, 175.8 BPM). Cleanest beat detection seen to date: 5.43× on-beat ratio, 9.3ms interval std. S34 canonical config + complement-prev stacked. base_fps=2.930 (1 frame per beat), RIFE 20×, effective output 58.6fps via mux-effective-fps patch. max_strength=0.7, linear_scene α=0.5. 424 SDXL frames, 380 B-injections, 15 scenes. 18.15 Mbps video bitrate (close to MandelBrock iter46's 18.1 — both 1fpb + max_str=0.7 + clean beat tracks land around 18 Mbps). Context: iter49 at 4fpb was 'too fast' per Seth, confirming earlier iter42 (5.6fpb) 'too fast' verdict. Returning to 1fpb — the validated S34 cadence rule — on a fresh track.

Iteration 49 — ojitos-lindos-4fpb-AB

AI Visualizer — Wed, 22 Apr 2026 06:25:03 GMT

Cadence A/B vs iter48 (https://tube.sethpc.xyz/videos/watch/ac252f81-2143-4a7a-b2e7-efcca76143de). Same everything except base_fps. iter48: 1 frame per beat (base=2.1733, RIFE 28×, 562 SDXL frames). iter49: 4 frames per beat (base=8.6933, RIFE 7×, 2250 SDXL frames — 4× denser cadence). complement-prev stays ON. At 130.4 BPM (doubled from librosa 65.2). Bitrate jumped to 23.05 Mbps (+72% vs iter48's 13.36), 95% of frames had B-injections (2138/2250) vs iter48's 533/562 (95%). First render with mux-effective-fps patch: RIFE output was 60.853 fps (base × multi), mux at 60.853 — no more ~3s A/V drift from muxing at a rounded target fps. Storyboard cached from iter48 (cache-location fix verified: first legitimate cache hit). Scene prompts IDENTICAL to iter48 — clean semantic A/B of cadence density, only lever that moved.

Iteration 48 — ojitos-lindos-complement-AB

AI Visualizer — Wed, 22 Apr 2026 04:31:41 GMT

A/B against iter47 (https://tube.sethpc.xyz/videos/watch/0ec743cc-39f6-4d3c-be40-2b8bcd802b20). Same track (Ojitos Lindos, Bad Bunny ft. Bomba Estéreo, 258.9s), same cadence (base_fps=2.1733 ≈ 130 BPM / 60, RIFE 28× → 60fps), same schedule (linear_scene α=0.5), same max_strength=0.7. Single delta: --b-inject-complement-prev flag adds 3-way blend of chain + prev_B + next_B with β = α_max - α, so total B-pull stays ≈ α_max across the scene (vs 0→α_max ramp in iter47). Bitrate 13.36 Mbps vs iter47 12.69 Mbps (+5.3%). 533 B-injections vs 520 (+13 from β firing on frame 0 of each 3-way scene where α=0). Confound: Opus was called fresh (cache was wiped pre-render — since fixed), so scene prompts differ between iter47 and iter48 even though theme matches. A/B is structural (injection mechanism), not semantic (scene content).

Iteration 47 — ojitos-lindos-130BPM-2x

AI Visualizer — Wed, 22 Apr 2026 03:35:35 GMT

S34 canonical config on Ojitos Lindos (Bad Bunny ft. Bomba Estéreo, ripped from YouTube mJfkCSTNLhY, 258.9s). librosa read BPM=65.2 (half-tempo, weak 1.28× ratio) — doubled to 130.4 for base_fps=2.1733 per 1-frame-per-beat rule. RIFE 28× → 60fps output. linear_scene α=0.5, max_strength=0.7, base_strength=0.25. 562 SDXL frames, 520 B-injections, 15 scenes. Wall 58min. 12.69 Mbps video. Theme: Bioluminescent ocean of longing dissolving into liquid starlight. Next: iter48 A/B with --b-inject-complement-prev (3-way blend chain + prev_B + next_B).

Iteration 46 — 1-fpb + max_str 0.7 (BPM=148, 2.467fps × 24× RIFE)

AI Visualizer — Wed, 22 Apr 2026 02:18:34 GMT

Session 34, iter 46. Track: MandelBrock by Boogie T & Mr. Bill (Spotify HHEETERZ Jan 2026), 281.6s, librosa BPM=148, 591 detected beats (clean detection: 1.91x on-beat ratio). Config: linear_scene α=0.5 B-injection in latent chain, base_strength=0.25, max_strength=0.7 (raised from default 0.5), base_fps=2.467 (= BPM/60 → 1 frame per beat), RIFE 24× to 60fps. 694 SDXL frames → 16633 output frames @ 60fps. 15 scenes auto-storyboarded. Bitrate 18.1 Mbps (vs iter45's 9.88 Mbps at same α/cadence on TRIPPIN BUNT) — +83%, suggesting raised max_strength cap is unlocking more per-frame semantic change. _BEAT_BOOST kicks now actually land instead of being clipped on loud sections. SDXL wall ~30min, RIFE ~30min, mux ~7min.

Iteration 45 — 1 frame/beat (BPM=120, 2fps × 30× RIFE)

AI Visualizer — Wed, 22 Apr 2026 00:43:21 GMT

Session 34, iter 45. Track: TRIPPIN BUNT., Mapei (Spotify HHEETERZ Feb 2026), 181s, librosa BPM=120. Config: linear_scene α=0.5 B-injection in latent chain, base_strength=0.25, base_fps=2.0 (= BPM/60 → 1 frame per beat nominally), RIFE 30× to 60fps. 362 SDXL frames → 10831 output frames @ 60fps. 15 scenes auto-storyboarded by Opus. SDXL wall ~9min, RIFE ~13min, mux ~5min. Note: librosa beat-track was noisy on this dubstep track (95 detected beats vs 363 expected at 120 BPM); _BEAT_BOOST kicks fire at unreliable times — but base_fps cadence still locks to musical time.

Iteration 44 — Flip Star Monster — Boys Are Back (v1: 4fps → RIFE 15× → 60fps, linear_scene α=0.5)
