The scripts detect editor format (top-level + `nodes` and `links` arrays) and tell you to re-export via + "Workflow → Export (API)" (newer UI) or "Save (API Format)" (older UI). + +2. **Server must be running** — all execution requires a live server. + `comfy launch --background` starts one. Verify with + `curl http://127.0.0.1:8188/system_stats`. + +3. **Model names are exact** — case-sensitive, includes file extension. + `check_deps.py` does fuzzy matching (with/without extension and folder + prefix), but the workflow itself must use the canonical name. Use + `comfy model list` to discover what's installed. + +4. **Missing custom nodes** — "class_type not found" means a required node + isn't installed. `check_deps.py` reports which package to install; + `auto_fix_deps.py` runs the install for you. + +5. **Working directory** — `comfy-cli` auto-detects the ComfyUI workspace. + If commands fail with "no workspace found", use + `comfy --workspace /path/to/ComfyUI ` or + `comfy set-default /path/to/ComfyUI`. + +6. **Cloud free-tier API limits** — `/api/prompt`, `/api/view`, `/api/upload/*`, + `/api/object_info` all return 403 on free accounts. `health_check.py` and + `check_deps.py` handle this gracefully and surface a clear message. + +7. **Timeout for video/audio workflows** — auto-detected when an output node + is `VHS_VideoCombine`, `SaveVideo`, etc.; the default jumps from 300 s to + 900 s. Override explicitly with `--timeout 1800`. + +8. **Path traversal in output filenames** — server-supplied filenames are + passed through `safe_path_join` to refuse anything escaping `--output-dir`. + Keep this protection on — workflows with custom save nodes can produce + arbitrary paths. + +9. **Workflow JSON is arbitrary code** — custom nodes run Python, so + submitting an unknown workflow has the same trust profile as `eval`. + Inspect workflows from untrusted sources before running. + +10. **Auto-randomized seed** — pass `seed: -1` in `--args` (or use + `--randomize-seed` and omit the seed) to get a fresh seed per run. + The actual seed is logged to stderr. + +12. **Model-directory mapping awareness** — `CheckpointLoaderSimple` + only searches `models/checkpoints/`. Models placed in + `models/diffusion_models/` (e.g. LTX video transformers, Flux unet) are + invisible to that node. Check `/api/object_info/CheckpointLoaderSimple` + to see what the server actually sees. Move the file, or use a node pack + that reads the correct folder (e.g. `DiffusionLoader` for + `models/diffusion_models/`). See the table in "Post-Install: Download + Models". + + **Concrete example from session:** `ltx-2.3-22b-dev-fp8.safetensors` placed + in `models/diffusion_models/` is invisible to `CheckpointLoaderSimple`. + Even if moved to `models/checkpoints/`, loading it via + `CheckpointLoaderSimple` fails with `"clip input is invalid: None"` because + the file is a transformer-only diffusion model with no bundled CLIP/text + encoder. Use a node pack that provides a dedicated loader for the model's + architecture (e.g. `UNETLoader` or `DiffusionLoader`) and wire in the + correct text encoder separately. + +13. **Resize source images before VAE encode when targeting exact output dimensions** — + VAE latent space has fixed compression ratios (typically 1:8 for SD 1.5, + meaning a 512×512 latent decodes to 4096×4096). If you need an exact output + resolution (e.g. 720×720 for a video platform), insert an `ImageScale` node + (lanczos, crop=center) **before** `VAEEncode`. Resizing after decode produces + blurry results; resizing the latent via `LatentUpscale` requires the target to + be a multiple of the VAE stride. The pre-encode `ImageScale` approach is the + most reliable way to hit arbitrary exact dimensions while preserving composition. + +14. **Node enum validation is strict** — ComfyUI validates enum fields + server-side against the exact values the node declares in + `/api/object_info/`. Passing values that look intuitive but + aren't in the enum list causes silent workflow rejection or cryptic + validation errors. Always query the node's `input.required` schema to + discover the exact allowed strings (e.g. `working_dtype` may only accept + `['float16','float32','auto']`, not `'bf16'`; `working_device` may only + accept `['cpu','auto']`, not `'cuda'`). + +14. **Credential ambiguity — stop and ask.** When the user says something like + "SSH n8n - passw0rd", they may mean host, user, or password in any combination. + Probe once with the most likely interpretation. If the password is rejected, + **stop immediately and ask** rather than writing elaborate PTY scripts or + guessing credentials. Do not loop through multiple usernames; don't build + `expect`-style scripts when the user can clarify in one message. + This pitfall appears because the `terminal` tool can't run interactive + SSH sessions, and every PTY workaround adds fragility. + +15. **Version-file staleness after manual git checkout** — + `comfyui_version.py` is auto-generated during build. After a manual + `git checkout v0.18.3`, the file may still report `0.18.1`. The running + server reports whatever this file contains, not what `git tag` says. + Either regenerate it (`python setup.py`) or edit manually, or verify + functionality via a test run rather than trusting the version string. + +## Verification Checklist + +Use `python3 scripts/health_check.py` to run the whole list at once.

TenStrip cond-safe is the solution — purpose-built for I2V at 1.0. + +### Deep Research Dispatch for Artifact Investigation + +When artifacts persist after applying the ranked fixes above, dispatch a focused deep-research pass with the exact setup and prompts. The pattern: + +1. **Write the full research question to a file** — include: exact model chain, all render settings, all scene prompts verbatim, what's been tried (v4, v5), and specific research questions (e.g., "does ID LoRA cause artifacts on full-body action scenes?", "is fp8_scaled the worst variant?") +2. **Dispatch to research profile:** `hermes -p research -s deep-web-research chat -q "Read the full research question from ..." -Q --max-turns 600 --yolo` +3. **Expected output:** `/home/n8n/workspace/research/results/-ltx-2.3-artifacts-deep.md` +4. **Do NOT poll** — the `deep-research` skill's post-dispatch rule applies.

ComfyUI v0.27.0's `execution.py:1121` expects `_meta` to be a dict and crashes with `AttributeError: 'str' object has no attribute 'get'` when it encounters a string. Fix: strip `_comment` before submitting. The `run_workflow.py` script does NOT strip this automatically — pre-process the workflow JSON first: + ```python + import json + with open('workflow.json') as f: wf = json.load(f) + wf.pop('_comment', None) # Remove the string field + with open('workflow_fixed.json', 'w') as f: json.dump(wf, f) + ``` + +2. **Checkpoint name mismatch.** The bundled `sd15_txt2img.json` expects `v1-5-pruned-emaonly.safetensors` but the .202 server has `v1-5-pruned.safetensors`.

The root cause: the story didn't flow between scenes. Each scene was a standalone vignette (wake up → kitchen → porch → forest → stream → overlook) with no causal chain. LTX needs a narrative thread where each scene follows from the previous one. + +### Story Design Rules + +1. **Chain of events, not vignettes.** Each scene must be caused by the previous scene. "She discovers something → she runs → she hides → she chooses." Not "he wakes up → he makes coffee → he walks outside." +2. **One character, one journey.** Multi-character stories cause identity drift. The ID LoRA helps but isn't perfect across different faces. +3. **No dialogue, no plot twists.** LTX can't do dialogue well. Visual storytelling: action, reaction, environment, choice. +4. **6 scenes × 10s = 60s.** This is the sweet spot. Each scene is one beat in the story. +5. **Clear visual variety per scene.** Each scene should have a distinct setting, lighting, and camera language. This prevents the model from blending scenes together. +6. **Match LTX prompt style for EVERY scene.** See Prompting Rules above. Every scene prompt must have: shot type, camera movement, subject action (present tense, sequential), lighting, audio. No exceptions. + +### Story Template + +``` +Scene 1: INCITING INCIDENT — character discovers/encounters something +Scene 2: ESCALATION — the situation intensifies, stakes rise +Scene 3: REACTION — character responds, makes a decision +Scene 4: CHASE/STRUGGLE — physical action, pursuit, or confrontation +Scene 5: LOW POINT — character is isolated, vulnerable, reflects +Scene 6: CHOICE/RESOLUTION — character makes the final decision, walks toward outcome +``` + +### User Preference: Detail Over Simplicity + +The user initially asked for simpler stories, then reversed: "go back to your original." The detailed 4-story cyberpunk templates (Ghost in the Wire, Chrome Angels, The Last Human Job, Neon Baptism) are the preferred level of detail. Each story has: logline, chain of events, per-scene setting/action/camera, and start frame requirements. See `references/story-structure-guide.md` for the full 4-story templates. + +## Multi-Story Workflow (CRITICAL — session 2026-07-21) + +**Run one story at a time, end to end.** Do NOT batch all 4 stories. Complete each story fully before starting the next: + +1. Generate start frames → wait for queue drain +2. Build scene JSONs → submit render → wait for queue drain +3. Verify frame counts (241 per scene, not 249) +4. Concat → upload to TrueNAS +5. Save all artifacts (prompts, JSONs, stock) to TrueNAS +6. Update state file +7. Only then start the next story + +**Before scaling to a full 6-scene story, test with 2 clips first.** A 2-clip test (shared background, camera pan between subjects) validates the model chain, prompt quality, and transition smoothness at minimal cost before committing to a full render. See `references/claude-live-ssh-inspection.md` for the pattern of having Claude SSH into .202 to inspect live state and build the test plan. + +### 2-Clip Test Pattern (Panorama + Frame-B Transition) + +Proven pattern for testing continuous camera motion across clips (2026-07-22, two iterations): + +1. **Generate one wide Flux panorama** (1536×512) with both subjects in a shared scene — guarantees identical background/lighting +2. **Crop 3 windows** (768×512 each): A (subject 1), B (center transition — EMPTY mid-room), C (subject 2) +3. **Clip 1:** Plain I2V from frame A, prompt drives a slow steady pan. Drop ID LoRA. +4. **Clip 2:** Plain I2V from **frame B** (the pre-rendered empty mid-room crop). Prompt continues the pan, reveals subject 2. + +**CRITICAL: Do NOT use true-extend (extract last frame from Clip 1 → use as Clip 2 start).** True-extend carries latent memory of subject 1 into Clip 2. LTX hallucinates a second figure at subject 1's location even though the start frame shows empty room. Confirmed 2026-07-22: Clip 2 generated a second woman stepping up from the couch where the man was. Fix: use the pre-rendered empty frame B as Clip 2's start frame — clean start, no latent memory. Small seam risk at boundary but eliminates hallucination. + +**Why frame-B transition, not FLF:** FLF (First-Last-Frame) decelerates toward its target keyframe — clip 1 slows down approaching B, clip 2 speeds up leaving it. This creates a velocity "hitch" at the seam. Frame-B transition uses plain I2V for both clips with the pre-rendered empty frame as Clip 2's anchor — constant velocity, no deceleration, no latent memory. + +Full plan at `~/workspace/general/plans/2026-07-22-2clip-test-plan.md`. See `references/2clip-test-pattern.md`. + +### Claude Live-SSH Inspection Pattern + +When you need a plan built from live system state (not from memory or docs), have Claude SSH into .202 and inspect before planning: + +1. **Write the question** to a local temp file, scp to 10.0.0.28 +2. **Include SSH credentials in the prompt** — Claude needs `sshpass -p 'passw0rd' ssh n8n@10.0.0.202` to reach .202 +3. **Tell Claude what to inspect** — model files, workflow JSONs, queue status, disk space, existing outputs +4. **Claude inspects live, then builds the plan** — it reads real workflow JSONs to understand node structure, checks which LoRAs are actually on disk, verifies queue is empty before submitting +5. **Claude writes the plan back** — it can scp files to 10.0.0.42 (the Hermes host) or save to .202 and have you retrieve them + +This pattern produced the 2-clip FLF panorama plan (2026-07-22) where Claude discovered: the Distilled LoRA on disk is the 384 variant (not 384-1.1), the ID LoRA is talkvid-trained (wrong for action scenes), and FLF example workflows exist on the box. None of this was in any state file — it was discovered by live inspection. + +**Pitfall:** Claude may error on first attempt (SSH timeout, tool failure). Resume the session with `--resume` and ask what went wrong — Claude self-diagnoses and recovers. The first attempt cost $1.05 (21 turns, is_error); the resume cost $0.11 (2 turns, success). + +**Save and document EVERYTHING.** After each story completes, upload to TrueNAS: +- `outputs/` — concat video +- `workflows/` — scene JSONs +- `docs/` — prompt documents, research +- `start_frames/` — Flux-generated frames +- `character_refs/` — stock reference images + +**Background wait pattern:** Use `terminal(background=true, notify_on_complete=true)` with a blocking poll loop on .202. The agent is notified when the queue drains — no manual polling needed. While waiting, prep the next story's prompts and stock. + +## Workflow Rules + +- **Always fp8.** Only fall back to Q4 GGUF if fp8 OOMs and user approves. +- **Prefer newest and best.** When choosing between an old proven path and a new better one, prefer the new one. But verify compatibility first — new doesn't mean compatible (e.g., the 2026-07-22 ComfyUI-LTXVideo update brought a better architecture that doesn't work with our fp8 models). +- **MANDATORY: Delegate ALL mechanical work to glm (NOT kimi-c).** Building workflow JSONs, running renders, extracting frames, submitting to queue, waiting for completion, concat, uploading — these are mechanical tasks that burn expensive deepseek tokens. Use `delegate_task` for ALL of these, targeting the glm profile. The calling agent stays lean for decision-making, validation, and user communication. This is a FIRM standing rule — do not do mechanical work yourself when a cheaper peer can do it. User directive 2026-07-22: "stop using ask kimi c for tasks, use glm instead." +- **File-based API submission.** Do NOT inline complex JSON in curl commands — Hermes' command parser blocks them. Write the workflow to a file (e.g., `/tmp/submit_ltx_render.sh`), then execute with `bash /tmp/submit_ltx_render.sh`. See `references/api-submission-pattern.md` for the complete pattern including polling, verification, and TrueNAS upload. +- **ALWAYS validate with glm after creating or updating anything.** Workflow JSONs, config changes, file writes — dispatch glm via `delegate_task` to read the file and verify correctness before submitting to the render queue. Glm catches wiring errors, missing nodes, and model file mismatches that would waste a 5-7 minute render. This is a quality gate, not optional. +- **Test one scene before rendering all 6.** +- **Verify frame count after every render (ffprobe).** +- **Save all artifacts to TrueNAS immediately** (user can only view videos on TrueNAS, not in LXCs). +- **Update state file as you go.** +- **Save learnings to fact_store proactively** — don't wait to be asked. +- **User prefers discussing design decisions before implementation.** + +### 1.

The research agent reports URLs; the dispatcher agent must manually download and upload. Future: extend `better-search-research` methodology to accept a `--target` parameter and auto-download top results to the specified stock directory. + +**Character reference sources (from better-search research):** +- freeaivideohub.com/character-sheets — 12 free photorealistic multi-view character sheets +- Pexels API — 700K+ free portrait photos, commercial use +- FFHQ — 70K faces at 1024×1024 (NVIDIA, non-commercial) +- CivitAI — community LoRAs and LTX workflows + +**Using stock as I2V start frames:** See `references/stock-as-i2v-start-frame.md` — pattern for using character stock images as direct I2V start frames without IC-LoRA Ingredients. Simpler, works with existing 6-fix baseline. For multi-clip character consistency, use IC-LoRA Ingredients instead. + +## Pitfalls + +- **CRITICAL: True-extend (extract last frame → use as next clip start) carries latent memory.** LTX remembers subjects from prior clips even when the start frame shows empty space. Confirmed 2026-07-22: Clip 2 hallucinated a second woman stepping up from the couch where the man was in Clip 1. Fix: use the pre-rendered empty mid-room frame B as Clip 2's start frame instead of the extracted last frame. Clean start, no latent memory. See §2-Clip Test Pattern. +- **ffmpeg last-frame extraction:** `ffmpeg -sseof -3 -i input.mp4 -vsync vfr -q:v 2 output.png` may fail. Working alternative: `ffmpeg -sseof -3 -i input.mp4 -update 1 -frames:v 1 -q:v 2 output.png`. The `-update 1` flag is needed for single-frame PNG output from video input. +- **CRITICAL: git pull on ComfyUI-LTXVideo may land incompatible native workflows.** The 2026-07-22 update (30K lines) brought a new native single-stage architecture (CheckpointLoaderSimple, LTXVScheduler, SamplerCustomAdvanced, GemmaAPITextEncode) that uses full checkpoints (46 GB), not our fp8 UNET-only transformer (23 GB). The new workflow drops LTXDirector entirely. Our fp8 chain (UNETLoader → LTX2LoraLoaderAdvanced → LTXDirector) is incompatible with the new architecture. **Before git pulling, snapshot the working state.** If the pull lands new example workflows, do NOT assume they work with our fp8 models — verify compatibility first. The new architecture requires a full checkpoint that won't fit 24 GB VRAM. +- **CRITICAL: Upload to TrueNAS after EVERY render.** The user can only view videos on TrueNAS (10.0.0.117), not in LXC containers. scp from .202 to Hermes host, then smbclient to TrueNAS. Do NOT skip this — the user has no other way to review output. (Learned 2026-07-22: user said "I can only view videos on truenas, not in lxc's.") +- **CRITICAL: Do NOT interrupt a running Claude session.** If Claude is mid-build (background process running), do not scp new question files or send follow-ups unless the user explicitly says "tell Claude now." Wait for the session to complete. Mid-build interruptions can cause the session to error out. (Learned 2026-07-22: sent a fact_store instruction mid-build; user corrected: "I said when claude is complete.") +- **CRITICAL: Claude's intermediate errors are normal self-correction.** Claude will make mistakes, hit errors, then try a different approach. `is_error: true` on intermediate turns does NOT mean the session failed. Wait for the final turn output. Only diagnose after the background process completes. Jumping to conclusions mid-session wastes turns and money. (Learned 2026-07-22: killed a working session twice, $1.78 wasted. User: "you just need to wait for the final turn output. Not jump to conclusions.") +- **Transition LoRA uses LoraLoaderModelOnly, not LTX2LoraLoaderAdvanced.** Wiring it wrong silently fails — the workflow runs but produces no transition effect. +- **`zhuanchang` trigger word is required** for Transition LoRA to activate. Append to end of segment prompts. +- **CFG must be 1.0** for distilled model. Higher values cause artifacts. +- **Queue is sequential** — submitting 6 scenes means ~30-40 min total. Use the blocking wait loop from step 5. +- **`process(action='wait')` timeout is clamped to 60s regardless of what you request.** The configured limit on the Hermes host caps wait timeouts at 60 seconds. For renders that take 5-7 minutes each, a single `process(action='wait', timeout=900)` will time out after 60s with the process still running. Pattern: use `process(action='wait', timeout=60)` in a loop, checking `status` after each call. When status is still `"running"`, call wait again. When status is `"exited"`, the queue has drained. Confirmed 2026-07-22: 2-clip render took 3 wait cycles (~3 min total) despite requesting 900s. +- **Output files accumulate** — the Director workflow produces 2 outputs per scene (guide pass + main pass). Identify the final output by checking for `LoraLoaderModelOnly` in metadata (Transition batch) or by resolution (512×512 = fp8 batch). +- **Output directory varies by workflow prefix.** The `SaveImage`/`SaveVideo` node's `filename_prefix` determines where files land. Workflows with prefix `LTX_Director_` go to `~/comfy-ui/output/video/`. Workflows with custom prefixes (e.g., `LTX_2clip_test_C1`) go to `~/comfy-ui/output/` directly. When identifying new outputs, search both directories: `find ~/comfy-ui/output -name "*.mp4" -newer -type f`. Do NOT assume all outputs are in `video/`.\n- **CRITICAL: Template file naming — verify you're using the right base files before re-rendering.** The .202 `/tmp/` directory accumulates multiple generations of workflow JSONs with confusingly similar names: `api_2clip_C1.json` (old living room test), `api_cyberpunk_C1.json` (cyberpunk test), `api_2clip_01.json` (earlier living room variant). When modifying and re-rendering, ALWAYS inspect the timeline_data segment's `imageFile` and `prompt` fields to confirm you're working with the correct template. A one-line Python check: `python3 -c "import json; d=json.load(open('/tmp/api_XXX.json')); td=json.loads(d['prompt']['131']['inputs']['timeline_data']); print(td['segments'][0]['imageFile'], td['segments'][0]['prompt'][:80])"`. Confirmed 2026-07-22: pointed delegation at wrong template, produced living room output instead of cyberpunk. +- **cifs kernel module not available** on Hermes host — use smbclient for TrueNAS, not mount.cifs. +- **smbclient is NOT installed on .202** — scp files to Hermes host first, then upload to TrueNAS from there. Do not try to install smbclient on .202 (no root access). +- **State file is the crash-recovery artifact** — update `~/workspace/general/ltx-pipeline-state.md` as you go. A new session reads it to resume. +- **ComfyUI API requires `{"prompt": }` envelope.** Submitting bare workflow JSON returns `"no_prompt"` error. Always wrap in the prompt key. +- **241 frames is normal for 10s@24fps.** The Director may produce 241 due to a 1-frame rounding quirk. 249 frames means the wiring bug is present (guide frames leaked). Verify with ffprobe. +- **Duration control: set `segment[\"length\"]`, NOT `duration_seconds` or `segment[\"end\"]`.** The LTXDirector ignores node-level `duration_seconds` and segment `end` — it uses `segment[\"length\"]` as the frame count. For 5s@24fps: `td[\"segments\"][0][\"length\"] = 120`. Setting only `duration_seconds` or `end` silently produces the full 10s output. Confirmed 2026-07-21: two failed attempts before finding the correct field. +- **Story must have a causal chain.** Standalone vignettes (wake up → kitchen → porch → forest) produce visual inconsistencies because the model has no narrative thread. Each scene must follow from the previous one. See `references/story-structure-guide.md` for the full 4-story templates and design rules. +- **User prefers detailed stories over simplified ones.** When the user said "keep it simple" and then "go back to your original," the original detailed templates were preferred. Don't over-simplify — the 4-story cyberpunk templates with loglines, scene tables, and character descriptions are the right level of detail. diff --git a/media/ltx-video-pipeline/references/2clip-test-pattern.md b/media/ltx-video-pipeline/references/2clip-test-pattern.md new file mode 100644 index 0000000..6c1933f --- /dev/null +++ b/media/ltx-video-pipeline/references/2clip-test-pattern.md @@ -0,0 +1,71 @@ +# 2-Clip Test Pattern — Panorama + True-Extend + +Proven 2026-07-22.

User: "stock test was malformed. It worked 80% but face distorted and did not stay to image." This approach is useful for quick composition tests only. For character consistency, use IC-LoRA Ingredients. +- **Character description in prompt MUST match the canonical descriptions** in `references/character-descriptions.md`. Using generic descriptions like "stern boss" instead of "muscular boss with shaved head and goatee wearing a black suit" causes the model to blend between the stock image and its own training data. The user provided exact descriptions — use them verbatim. +- **White/light backgrounds in stock images** may cause LTX to hallucinate background elements or wash out the scene. The model was trained on varied backgrounds; a plain white background gives it no environment cues. Prefer stock with scene-appropriate backgrounds, or use Flux to generate a start frame that composites the character into the target environment. +- **Stock image aspect ratio** rarely matches 768×512. Resize with LANCZOS; avoid stretching (crop to aspect ratio first if needed). +- **This is NOT a character-consistency solution across clips.** Each clip gets its own start frame; there's no mechanism to keep the same face across scenes. For multi-clip consistency, use IC-LoRA Ingredients. diff --git a/media/ltx-video-pipeline/references/story-structure-guide.md b/media/ltx-video-pipeline/references/story-structure-guide.md new file mode 100644 index 0000000..9c74882 --- /dev/null +++ b/media/ltx-video-pipeline/references/story-structure-guide.md @@ -0,0 +1,134 @@ +# Story Structure Guide — LTX Video Pipeline + +## The Problem (v4 Post-Mortem) + +v4 rendered correctly (241 frames, no duplication, wiring fixed) but the user said "the videos had all kinds of inconsistencies."
