# LTX 2.3 INT8 Director Control
## Summary
`LTX 2.3` Director workflow with INT8 optimization. This is the timed multi-keyframe control path from the same-day `javawock7618` pack.
## Model Family
- `ltx`
## Status
- `imported-only`
## Source
- Workflow pack page: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows>
- Workflow file: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows/resolve/main/LTX2.3_int8_Director-javano2607.2.json>
- Original publisher: `javawock7618`
- Date imported: `2026-08-09`
## Developer notes
- This is the Director / multi-keyframe variant from the pack.
- The source README describes it as the visual timeline / camera choreography workflow.
- It shares the same base requirements as the other LTX 2.3 pack workflows.
## Our notes
- This is the most interesting new LTX import if you want to push composition and scene timing, not just plain prompt-to-video.
- On an `RTX 3070`, this is still more of a careful test than a casual one, but it is the right kind of control workflow to keep.
- Good watch item for future character-sheet or shot-planning style builds.
## Required custom nodes
- `ComfyUI-KJNodes`
- `ComfyUI-LTXVideo`
- `keyframeflf` / `flf` helpers used by the pack
## Required models
- `lightricks/ltx-2.3` distilled GGUF or INT8 weights, depending on the local setup
## Notes
- Best same-day LTX workflow for timeline and camera-control experiments.

# LTX 2.3 INT8 Multi-Subject Reference
## Summary
`LTX 2.3` multi-subject reference workflow with INT8 optimization. This is the one from the `javawock7618` pack that matters most for reference-heavy scene building.
## Model Family
- `ltx`
## Status
- `imported-only`
## Source
- Workflow pack page: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows>
- Workflow file: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows/resolve/main/LTX2.3_int8_MSR-javano2607.2.json>
- Original publisher: `javawock7618`
- Date imported: `2026-08-09`
## Developer notes
- Comes from the same-day `javawock7618` LTX 2.3 workflow pack.
- The pack describes this as the `Multiple Subject Reference` path, with up to five input references.
- INT8 is the main reason to keep this one around instead of treating it as a novelty pack.
## Our notes
- This is the strongest new LTX import for character, object, and multi-reference consistency.
- It is probably still heavy on an `RTX 3070 / 8 GB`, but the INT8 path makes it the most practical version of this idea to keep testing.
- Good candidate for later comparison against the repo's simpler LTX character-sheet workflows.
## Required custom nodes
- `ComfyUI-KJNodes`
- `ComfyUI-LTXVideo`
- `keyframeflf` / `flf` helpers used by the pack
## Required models
- `lightricks/ltx-2.3` distilled GGUF or INT8 weights, depending on the local setup
## Notes
- Best same-day LTX workflow for reference and subject-composition work.

# LTX 2.3 INT8 Video-to-Video
## Summary
`LTX 2.3` video-to-video workflow with INT8 optimization. This is the practical edit path from the same-day `javawock7618` pack.
## Model Family
- `ltx`
## Status
- `imported-only`
## Source
- Workflow pack page: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows>
- Workflow file: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows/resolve/main/LTX2.3_int8_v2v-javano2608.1.json>
- Original publisher: `javawock7618`
- Date imported: `2026-08-09`
## Developer notes
- The source README describes this as the INT8 `video-to-video` workflow.
- It is the closest match in the pack for edit, transform, and motion-transfer use.
- This is a better fit than the more novelty-ish LTX audio paths for everyday local work.
## Our notes
- Likely the most practical of the new LTX pack imports for normal local testing.
- Still not light, but the INT8 path gives it a real shot on the `3070` compared with heavier reference-heavy variants.
- Good baseline for edit-quality comparisons against the simpler LTX workflows already in the repo.
## Required custom nodes
- `ComfyUI-KJNodes`
- `ComfyUI-LTXVideo`
## Required models
- `lightricks/ltx-2.3` distilled GGUF or INT8 weights, depending on the local setup
## Notes
- Best same-day LTX workflow for day-to-day video editing and motion transfer.

# MiniMax H3 INT8 First-Last-Frame
## Summary
`MiniMax H3` first-last-frame workflow from the same-day `javawock7618` pack. This is the controlled transition path for image-guided video.
## Model Family
- `minimax`
## Status
- `imported-only`
## Source
- Workflow pack page: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows>
- Workflow file: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows/resolve/main/MiniMax_int8_I2V-javano2608.6.json>
- Original publisher: `javawock7618`
- Date imported: `2026-08-09`
## Developer notes
- The source README describes this as the `First-Last-Frame` workflow.
- It uses INT8, Sol-Attn, Spectrum acceleration, Motion Context, Lightx2v LoRA, Turbo LoRA support, and latent upscaling.
- The pack says the FLF workflow is the one that uses Motion Context.
## Our notes
- Strongest new MiniMax import for controlled transitions and scene morphing.
- On a `3070`, this looks tight to heavy, but the INT8 path is the only reason it feels worth trying locally.
- Good candidate to compare directly against LTX first-frame or multi-reference workflows.
## Required custom nodes
- `ComfyUI-SolAttn_triton`
- `ComfyUI-Spectrum-MiniMax-H3`
- `ComfyUI-H3-Motion-Context`
- `ComfyUI-MiniMaxH3_LatentUpscaler`
## Required models
- `Comfy-Org/MiniMax-H3`
- `Kijai/MiniMax-H3_comfy`
- `drbaph/MiniMax-H3-Turbo-Lora-ComfyUI` if the turbo path is enabled
## Notes
- Best same-day MiniMax workflow for first/last-frame control.

# MiniMax H3 INT8 Reference-to-Video
## Summary
`MiniMax H3` reference-to-video workflow from the same-day `javawock7618` pack. This is the more direct character-consistency path.
## Model Family
- `minimax`
## Status
- `imported-only`
## Source
- Workflow pack page: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows>
- Workflow file: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows/resolve/main/MiniMax_int8_R2V-javano2608.7.json>
- Original publisher: `javawock7618`
- Date imported: `2026-08-09`
## Developer notes
- The source README describes this as the `Reference-to-Video` workflow.
- It keeps the same INT8, Sol-Attn, Spectrum, Lightx2v, Turbo LoRA, and latent-upscaler stack as the FLF workflow.
- Motion Context is not part of this one, which may make it the cleaner baseline.
## Our notes
- This is the MiniMax import most worth comparing against LTX reference-control workflows.
- It is still heavy for an `RTX 3070`, but it is the most practical way in this pack to test whether MiniMax H3 is becoming more than a curiosity.
- Good choice when you care more about reference retention than keyframe choreography.
## Required custom nodes
- `ComfyUI-SolAttn_triton`
- `ComfyUI-Spectrum-MiniMax-H3`
- `ComfyUI-H3-Motion-Context` is not used here
- `ComfyUI-MiniMaxH3_LatentUpscaler`
## Required models
- `Comfy-Org/MiniMax-H3`
- `Kijai/MiniMax-H3_comfy`
- `drbaph/MiniMax-H3-Turbo-Lora-ComfyUI` if the turbo path is enabled
## Notes
- Best same-day MiniMax workflow for reference retention.

# MiniMax H3 Turbo v4 8-Step T2VA
## Summary
`MiniMax H3` text-to-video-plus-audio workflow tuned for the Turbo v4 LoRA and an 8-step recipe. This is the practical fast-path the same-day `BennyDaBall` release is aiming for.
## Model Family
- `minimax`
## Status
- `imported-only`
## Source
- Workflow pack page: <https://huggingface.co/BennyDaBall/MiniMax-H3-Workflows>
- Workflow file: <https://huggingface.co/BennyDaBall/MiniMax-H3-Workflows/resolve/main/MiniMax_H3_Turbo_v4_8step_T2VA_BennyDaBall.json>
- Original publisher: `BennyDaBall`
- Date imported: `2026-08-09`
## Developer notes
- The source README says this workflow uses only core ComfyUI nodes.
- It is set up around the `minimax_h3_turbo_v4_step600_ema_pruned_comfyui` LoRA.
- The workflow bundles a prompt pattern for timed audio and dialogue control.
## Our notes
- This is the most immediately usable MiniMax release of the day for simple prompt-to-video testing.
- If MiniMax feels like a real option on the `3070`, this is the first workflow I would try before the heavier reference-control packs.
- Still likely tight on `8 GB` once you keep the official MiniMax model stack in memory, but the 8-step recipe is the main reason it is worth a look.
## Required custom nodes
- none beyond current official ComfyUI MiniMax support
## Required models
- `Comfy-Org/MiniMax-H3`
- `drbaph/MiniMax-H3-Turbo-Lora-ComfyUI`
## Notes
- Best same-day MiniMax workflow to test first.

"Style contract: photoreal cinematic live-action, warm 1950s American diner interior, chrome counter, red vinyl stools, soft window daylight, natural skin tones. One single continuous locked shot, no scene cuts. A cheerful waitress in a mint-green 1950s diner uniform with a white apron and a small paper cap stands behind the counter facing camera; a slice of cherry pie on a white plate sits on the counter in front of her.\nTimed beats:\n0.0-0.6s: she wipes her hands on her apron, glancing down at the pie.\n0.6-1.4s: she slides the plate forward across the counter with a soft ceramic clink and looks up at camera with a warm smile.\n1.4-3.6s: (S1) says: <d>[English] Fresh out of the oven, sugar — careful, that plate's hot.</d> Her lips sync naturally to the line; she raises her eyebrows playfully on the word hot.\n3.6-5.1s: she rests both hands on the counter, tilts her head, smiling, steam rising gently from the pie.\nCamera: completely static and locked-off — no pan, no tilt, no zoom, no drift. Medium shot at counter height.\nAudio: at 0.0s quiet diner room tone with a faint refrigerator hum and distant clink of dishes; soft apron fabric rustle 0.0-0.6s; a ceramic plate slide and clink at 0.6s; her clear warm female voice speaking at 1.4-3.6s; a soft single counter-bell ding at 4.3s; room tone continues to the end. No music.\nNegative: no on-screen text, no captions, no watermark, no scene cuts, no camera motion, no morphing hands, no extra fingers, no second person, no music.",

"## MiniMax H3 + Turbo v4 LoRA — 8-step video+audio\n\nText → video with **native stereo audio** (voice, SFX, room tone in one pass), ~**1.9× faster** than the stock 20-step recipe. Verified with a same-seed A/B against the 20-step baseline: same choreography, healthy audio (peak ≈ −9 dB, zero clipping).\n\n**The recipe**\n- Turbo v4 LoRA at strength **1.0** via the built-in *LoraLoaderModelOnly* — this graph is 100% core ComfyUI nodes, no custom node packs\n- **8 steps · euler · beta** — no sigma-shift node needed; core defaults carry the dual video/audio clock at this step count\n- CFG-free (BasicGuider): there is no negative-prompt input — write a `Negative:` line inside the prompt itself (see the demo prompt)\n- **1344×768 @ 24 fps**. `length` is frames on a 17k+5 grid: **124 ≈ 5 s**, 243 ≈ 10 s, 362 ≈ 15 s (model max)\n- Seed is **fixed** so your first run reproduces the demo clip; set it to *randomize* for new takes\n\n**Tested / not tested**\n- Verified on 5-second clips at 1344×768. Higher res (1920×1088) and longer clips are untested with this LoRA — earlier turbo versions fell apart there, so treat that as experimental\n- First run: watch the console — you should see **zero** \"lora key not loaded\" warnings on the pruned int8 checkpoint\n- Few-step audio blowout is the classic turbo failure mode; this v4 @ 8 steps is the combo that passed. If you drop steps further, check your audio peaks\n\n**Prompt pattern that works**\nStyle contract → timed beats (`0.0-0.6s: ...`) → camera lock line → an audio timeline starting with room tone at 0.0s → `Negative:` line. Dialogue inside `<d>[English] ... </d>` is spoken verbatim with lip-sync. Give the first spoken line ≥1.2 s of lead-in and anchor t=0 with room tone.\n\n*LoRA: larryvrh's MiniMax-H3-Turbo-Lora (v4_step600 EMA), ComfyUI convert by drbaph.
