MiniMax H3 Unified — Lip-sync, Scene Prompts and Resumable Video

Workflow: MMH3_Unified.json
Guide updated: 8 November 2026

Create a performance video from an existing recording, or generate video and audio from text and images. Both paths use the same render loop, with a prompt for each scene, an accumulated preview, and saved runs you can continue or replace from a selected part.

The optional reference-video analysis finds scene boundaries and describes the movement between them. You can use those results directly or enter all timings and prompts manually. Optional YuE2 and MiniMax Music 3 groups can create a soundtrack; lyric extraction and animated captions are also included.

Recommended first test: Use a short excerpt, leave music generation and captions off, and generate one part per queue. Keep Disk and Keep in output enabled so you can continue from the result.

Choose what you want to make

Lip-sync: animate a reference image to an existing song, dialogue or other vocal recording. Use manual scene prompts or copy the editing rhythm and gestures from a reference video.
Native H3: generate from text, a starting image, first/last images, different images for different scenes, or visual references. Supply a soundtrack or let H3 generate the sound.
Resume: continue an unfinished saved run without generating the completed parts again.
Replace: keep the beginning of a saved run and generate a new version from a chosen part onward.
Load: reuse a saved run for captions or another export without sampling the video again.

The workflow is organized into groups and subgraphs. Open a subgraph when you need its additional controls; most everyday changes are on the main canvas. The groups share their values through Get/Set routing.

Install and open the workflow

Use a ComfyUI build with native MiniMax H3 support. The working setup for this guide uses ComfyUI 0.42.1. YuE2 and MiniMax Music 3 support is needed when enabling their optional groups.

Install or update these Nova packs, including their dependencies in the Python environment used by ComfyUI:

ComfyUI Eclipse Nova — input panels, scene analysis, planning, the render loop, saved runs, previews and captions.
ComfyUI Smart Model Loader Nova — H3/music loaders, loader presets, LoRA presets and Download Manager.
ComfyUI SmartLLM Nova — reference-frame descriptions and optional music/lyric prompting.

The optional patch groups contain nodes from ComfyUI-sol-attn, including Diff-Aid. Vocal separation uses Audio Separation Nodes. Install those packs to have every included node available; their processing groups can stay muted for the first test.

Restart the ComfyUI backend after installing or updating Python nodes, then refresh the browser and open the workflow. The render and analysis loops are provided by Eclipse Nova; Easy-Use is not required.

Replace the example image, video and audio selections with your own files. An unavailable example saved-run selection is harmless in New run mode. Resume and Load require a run that exists on your computer.

Models, presets and downloads

Switch the generation path and both presets

In START HERE, choose Lip-sync or Native H3. Then select the matching setup in both Smart Model Loader and LoRA Stack:

Lip-sync: MiniMaxH3_LipSync in the loader and the separate LoRA preset list.
Native H3: MiniMaxH3_TFL2VA in both lists.

These presets belong to Smart Model Loader Nova. Use its current template files, or save your own versions after choosing your local models. Loading the workflow preserves its embedded settings, but your local preset list is managed separately.

Check when switching: The generation-path buttons do not automatically load model or LoRA presets. Check all three selections before queueing. The analysis task and appearance option are separate choices too.

H3 files used by this setup

Both paths need an H3 diffusion model, the MiniMax H3 Qwen3-VL 32B text encoder, the H3 video VAE and the H3 audio VAE.

Saved native model: minimax/h3ErosMax_beta7_3329966.safetensors. Its exact Civitai AIR is already stored in the loader's source details:
urn:air:minimaxh3:diffusionmodel:civitai:2851079@3429412+3329966
H3 ErosMax — saved model version
Lip-sync preset model: minimax_h3_fl2va_pruned_int8_convrot.safetensors, available from Comfy-Org/MiniMax-H3. Store it in ComfyUI/models/diffusion_models/, optionally in a minimax subfolder.
H3 text encoder: the workflow calls its local file qwen3-vl-32b-minimax-h3-int8-convrot.safetensors. The official INT8 ConvRot file uses underscores and has the same SHA-256. Download it into ComfyUI/models/text_encoders/ and select its actual filename in the loader.
Video VAE: minimax_h3_video_vae_fp16.safetensors.
Audio VAE: minimax_h3_audio_vae_fp32.safetensors.

Both VAEs are in the H3 VAE folder; place them in ComfyUI/models/vae/.

For native endpoint modes, choose an FL2VA-compatible model. For reference_images, choose a Ref2VA-compatible model; the official H3 repository also provides minimax_h3_ref2va_pruned_int8_convrot.safetensors. Check the model author's supported modes when using a community model.

Two different language-model roles: H3's 32B encoder is part of video generation. The smaller vision model in Smart LM describes reference frames. Installing one does not replace the other.

Use a saved AIR in Download Manager

An AIR identifies the selected Civitai resource. The saved AIRs here include the version and exact file, so you can find the intended download even when the workflow's local filename is missing.

In Smart Model Loader, open the missing resource's Source / integrity controls. For a LoRA, use the row's i button.
Keep the saved CivitAI source and AIR, or paste an AIR into the source field.
Click Open in Download Manager. Review the listed file and its destination: diffusion_models, text_encoders, vae or loras, as appropriate.
Select the file and click Add Selected to Queue.
Open Queue, select the ready job and click Start Selected.
After completion, the originating field receives the downloaded filename and verified source information. Save the workflow and use Save… if you want to update your preset too.

Keep the workflow open while downloading if you want automatic assignment to the original field. If you reload the browser, select the completed file manually afterward. Opening a workflow or the download panel does not start downloads automatically.

For files without a saved AIR, choose Hugging Face, enter the linked repository or file URL, and follow the same queue/start steps. Model access may require your provider account; configure it through the pack's supported settings. See the illustrated Download Manager guide.

LoRAs and sampling

The saved native setup uses Euler / simple, CFG 1 and 8 steps. Its three LoRA rows are currently disabled:

MysticXXX_MMH3-V5.safetensors — AIR urn:air:minimaxh3:lora:civitai:2856467@3416478+3309543.
Minimax H3 Cinematic Look.safetensors — AIR urn:air:minimaxh3:lora:civitai:2908686@3289775+3174203.
minimax_h3_fl2v_turbo_8step_v1.0_comfyui_bf16.safetensors — available in the official H3 LoRA folder.

Disabled rows do not need their files downloaded for execution. Enable only the additions you intend to use.

The lip-sync presets contain a different setup: 4 sampling steps, with these two LoRAs enabled at strength 1:

minimax_h3_PDMD_DMAD_4step_r256_add_fro1_turbo_lora.safetensors — from Darksidewalker's MiniMaxH3 repository, in its LoRA files. This repository requires accepting its access conditions.
minimax_h3_turbo_v4_step600_pruned_comfyui.safetensors — publisher's file.

Place LoRAs in ComfyUI/models/loras/ and select the actual local filenames. These describe the supplied presets; they are not universal settings for every H3 model. When substituting a checkpoint or accelerator LoRA, use its author's compatible sampling settings and save that combination as your own preset.

Models needed only for optional features

Reference analysis / automatic prompting: the example Smart LM selection is qwen3-vl-8b-heretic-1.3.0-int8-convrot.safetensors using the ComfyUI backend. Its recorded file source is:

urn:air:qwen2:text_encoders:civitai:2955374@3347601+3234858

Use this AIR in the standalone Download Manager, download to models/text_encoders, then refresh and select the model in Smart LM. You can choose another supported vision model for scene analysis, including a configured Ollama model. Text-only lyric prompting does not require vision. Backend setup is covered in the SmartLLM README.

Lip-sync activity encoder: the included audio-encoder branch selects wav2vec2_large_english_fp16.safetensors. Put it in models/audio_encoders/; it is available in Comfy-Org's audio-encoder files. Native H3 generation does not use this separate encoder.

YuE2: select yue2_3b_int8_convrot.safetensors from Comfy-Org/YuE2 checkpoints, under models/checkpoints/. Its loader uses the checkpoint's included text encoder and VAE.

MiniMax Music 3: the saved local names are minimax/minimaxMusic_v30_fp32.safetensors, qwen3-8b-minimax-music-v30-3107729-bf16.safetensors and minimax_music3_dav.safetensors. For a setup from Comfy-Org/MiniMax-Music-3, select minimax_music3_dit_fp32.safetensors, minimax_music3_text_encoder_pruned_bf16.safetensors and minimax_music3_dav.safetensors in the corresponding diffusion-model, text-encoder and VAE folders. Select the downloaded files in the Music 3 loader rather than leaving unavailable example names.

Whisper and optional Qwen timing setup are described in the captions section below. Leave unused groups muted; their models are not needed for a basic video run.

Find the main controls

START HERE · run mode + opt inputs: choose the generation path, then enable Images, Audio override, Reference video, Live analysis and LS vocal isolation as needed.
Shared H3 loader + separate LoRA presets: choose the model setup for that path.
Canvas + output folder · 24 FPS: choose aspect ratio, resolution and delivery folder. Keep H3 at 24 FPS.
Optional images / Reference video / Optional audio override: load your source material and set any excerpt.
Global prompts / Manual cut times + first / next part prompts: write the overall direction and individual scenes.
Part source / MMH3 Reference Analysis: inspect which prompt source is active and review generated scene text.
Run operation + saved-run selection: choose New, Resume or Load, storage, and the saved run.
Shared H3 render loop: set the render seed, part limit and native image mode; watch the assembled preview.
Shared result + save video: review part ranges and export, with optional lyric captions.

First run: lip-sync to your recording

Choose Lip-sync and load the matching loader and LoRA presets.
Turn Images on and load one image in Load Image Timeline. Choose the canvas size and check the crop.
Turn Audio override on and select your recording in Load Audio. For this first test, turn Reference video and Live analysis off and keep both music-generation groups muted.
Choose a short excerpt using Shared clip start (seconds) and the duration on H3 clip (shared caption trim). Duration 0 keeps the remaining recording, so enter a short duration deliberately.
Clear the example manual cut times and first/next prompts if you want one simple performance. Keep a short global direction such as: “The subject sings to the supplied audio with natural head movement and expressive eyes.”
Choose New run, Disk, and Keep in output. Set Parts per queue to 1 in Video loop · saved inputs + resume.
Queue and review the result. To continue a longer plan, select the saved run and follow the Resume steps below.

The lip-sync planner's saved strategy is warmup_reset, with a three-second warmup for later reset parts. Warmup gives the model time to settle into the next shot before those hidden frames are removed. The accumulated preview shows the retained result and its join with the previous part.

Opening pose: The first frame still comes from your reference image. If the prompt starts with hands beside the head but the image has hands at the waist, the model may first move them upward. For a very short opening scene, use an image already close to the intended pose.

First run: native H3 from text or images

Choose Native H3 and select the matching loader and LoRA presets.
For a manual text test, turn Live analysis, Reference video and Audio override off. Leave the music and caption groups muted.
Set reference_mode on Video loop · saved inputs + resume to text_only. Turn Images off too when you do not need them.
Write Native H3 global direction + sound, then the manual first-part prompt. Clear old next-part text and cut times for a single-scene test.
Set Duration in Total duration + maximum render window (native H3), for example 8 seconds. This duration is used when neither audio nor a reference video supplies the length.
Choose New run, persistent disk storage and one part per queue. Queue and review.

To use an image, turn Images on, select your file and change reference_mode to first_only. For endpoints, add two images and select first_and_last.

Native H3 builds longer videos from short renders. The saved Max clip frames = 362 is about 15 seconds at 24 FPS. Longer scenes split into additional renders while keeping their scene prompt and image assignment. Those renders are independent; a shared prompt or image does not guarantee continuous movement or generated sound at every join.

Generate, resume and replace parts

The operation dropdown has three choices: New run, Resume saved run and Load saved run. Replacement uses Resume saved run together with Restart part; it has no separate operation button.

Save a run that survives a restart

In Video Run Storage, enable Disk and Keep in output. The saved workflow uses the output directory runs, so working runs appear beneath ComfyUI/output/runs/. Each run gets its own folder. The final delivery video uses the separate Smart Folder destination, currently video/H3 with a date subfolder.

Disk + Keep in output: retains completed parts and the saved inputs needed to resume after restarting ComfyUI.
Disk + Temporary: reduces accumulated memory use, but the working files follow the temporary cache lifetime.
RAM: keeps decoded parts in CPU memory. It uses more RAM and is not persistent across a restart. Preview and final export still create video files.

Recommended: Use Disk + Keep in output while developing a video. Every completed part is saved, so a later interruption does not discard the earlier work.

New run

Select New run when starting a new video or changing its source material, prompts or timing plan. It resolves those inputs and begins a fresh run on each queue.

Parts per queue controls how much work happens before returning:

0 renders all remaining parts.
1 renders one new part for review.
A larger value renders that many new parts, or stops earlier when the plan is complete.

Important: Queueing New run again starts another run. To build on what you just generated, select its saved run and change the operation to Resume saved run.

Stop at a useful review point

Click Render loop · stop after current part → Stop after current part on the main canvas, below the render seed controls in Shared H3 render loop. It lets the current part finish, saves it, updates the accumulated preview and then stops the loop. You can use it without opening the subgraph or queueing again. The button inside Video Loop Start works too. For predictable step-by-step work, set Parts per queue to 1 before queueing instead.

The preview contains all retained parts so far, including the latest transition. In lip-sync mode, use it to judge the movement and audio around the warmup-trimmed join, rather than judging the new clip on its own.

An immediate ComfyUI cancellation can interrupt the current generation. Previously committed parts remain saved; the unfinished part must start again when resumed.

Resume an unfinished run

In Load Video Run, click Refresh runs and select the run you want to continue. Check Run progress + saved path or Saved run / part ranges if several runs look similar.
In Video Run Storage, select Resume saved run. Keep Disk + Keep in output enabled for the new result.
Keep the matching Lip-sync / Native H3 path, H3 model and LoRA setup selected.
Set Restart part = 0. This means continue after the last completed part.
Set Parts per queue to 1 for another review step, or 0 to finish the remaining plan.
Change Render seed · change before queueing if you want a new seed for the next generated parts, then queue.

Resume restores the saved prompts, timings, reference images, canvas and audio. It does not request another reference-analysis pass. Loaded model objects are not stored with the run, so the selected model, LoRAs and sampling settings still matter.

A completed run resumed with Restart part 0 returns the completed media without generating more parts.

Replace a bad part and the remaining ending

Suppose parts 1–6 look good, but part 7 has an unwanted gesture or appearance change:

Stop after the current part, or wait for the queue to finish.
Select that saved run and choose Resume saved run.
Set Restart part = 7. Part numbers start at 1; use the part-range report to find the correct number.
Change the Render seed before queueing. Leave Parts per queue = 1 to review the replacement first.
Queue. Parts 1–6 are retained as saved media; part 7 is generated again.
Review the accumulated preview, including the join from part 6 to the new part 7.
Select the newly created run, set Restart part back to 0, and resume to continue its ending. To try part 7 again, keep the restart value at 7 and choose another seed.

Persistent resume writes a new run folder and leaves the original run available for comparison. Before the next continuation, refresh the list and select the new revision you want to build on.

Replacement scope: Restart part N replaces N and everything after it. It does not splice one replacement into an otherwise preserved ending. A long scene can contain several render parts, so scene numbers and part numbers may differ.

Do not delete individual part files to force a restart. Use Restart part instead; deleting files can make the saved run incomplete or unloadable.

Seeds and edits during resume

The Render seed is connected to generation independently of the upstream analysis and planning. Changing it before the next queue changes the newly rendered parts; it does not regenerate the retained beginning. Different seed per part varies the seed across part positions.

The current queue already has its settings. Editing the seed while it is running does not change the clips still being generated in that queue. Stop, adjust, and queue Resume again.

Saved-input rule: Resume uses the prompts, timings, images and audio stored with that run. Editing the manual prompt boxes does not rewrite its saved inputs. Use New run for a changed scene plan or new source material. The current replacement controls are for rerendering saved parts with a different seed or generation setup.

Load a run for captions or export

Select a run and choose Load saved run to reuse its media. This skips generation, analysis and fresh planning, so you can change caption styling or output settings and export again. The source audio loaders stay inactive; the saved run supplies its own recording.

Keep the whole run folder if you move or back it up. It contains the ordered parts, audio and input checkpoint. NumPy .npy files hold pixel or saved-input arrays; they are not independently playable videos. The manifest tells the loader how those files belong together.

To reuse a moved run, place its complete folder under ComfyUI's output directory and click Refresh runs. Older media-only runs can be loaded for export but need a render checkpoint to support Resume. Saved output runs remain until you remove them, so clean up unwanted revisions when you are finished.

Scene prompts and cut times

Each scene receives the global direction plus its own part prompt. A list of scene prompts is not sent as one long instruction to every clip.

Global prompt: the performance or visual direction that applies throughout.
Manual first part: the opening framing, pose and movement.
Manual next parts: one nonempty line per subsequent scene. Keep each description on one line; the workflow carries these as a list.
Manual cut times: comma-separated seconds from the start of the selected excerpt.

For a 40-second video, cut times 8, 23, 31 create scenes lasting 8, 15, 8 and 9 seconds. Use one first-part prompt and three next-part prompts.

In Native H3, blank cut times divide the duration equally between the supplied scene prompts. Explicit times, including measured reference-video times, take priority. For a single global performance, clear the cut times and all part-specific text.

Write compact generation directions. For example:

Global: The subject performs naturally to the supplied audio with synchronized lip movements.

First part: Medium close-up with a static camera. Both hands are already beside the temples; the index fingers make small circles while the eyes widen.

Next part: Tight close-up. The subject lowers their chin slightly, holds eye contact and gives a brief sideways smile.

There is no need to write clip timestamps, warmup instructions or audio-priority rules into these paragraphs. The workflow handles timing and audio selection. A gesture already in progress should be described that way, especially when the scene is short.

Use a reference video for cuts and movement

Enable Reference video, load the clip and choose the excerpt you want. Enable Live analysis to measure its scene boundaries and describe the action inside each scene.

The workflow uses two separate passes:

Scene Detector finds visual scene changes on CPU at a low resolution. The saved longest side is 128 px.
Smart LM describes selected frames from each scene or window. Its separate Image handling → Longest side is 512 px in this workflow, preserving more detail for faces and gestures.

The saved analysis plan selects 8 frames per scene, with a maximum of 8 per window. Increase sampling when brief gestures are missing, while keeping the per-window limit manageable. Together: On lets Smart LM compare the selected frames in order.

Every Nth frame in Scene Analysis Plan samples original video frames. In Smart LM it subsamples the images it receives. Usually leave the LM stride at 1 if you already reduced the selection in the plan. Longest side 0 uses the loader's automatic model limits; a positive size is still bounded by supported limits.

Scene Cut Limit controls how dense the editing can be. The saved value 2 keeps boundaries at least half a second apart. 1 requires one second; 0 keeps all detected cuts. This removes boundaries without moving the retained ones, so reducing the limit merges some scenes and changes their descriptions.

Choose the description task for your purpose

Using a separate character image: choose Scene Motion Analysis in Smart LM and Exclude source appearance in Scene Analysis to H3. The focus is framing, pose, movement and expression.
Text-to-video with full scene descriptions: choose Scene Description (T2V) and Include source appearance. Clothing and other visible details can then be useful prompt content.

The saved workflow currently has the T2V task and include-appearance option selected. Change both when transferring motion to a separate reference image. Also read the selected global prompt and replace any instruction that does not fit your project.

Review before rendering: A vision model can still invent movement, miss finger gestures or include unwanted clothing. The task selection guides it but cannot guarantee compliance. Read the first/next prompt previews and compare questionable scenes with the source.

Live analysis has priority while enabled. To correct its output, copy the cut times and first/next prompts into the manual fields, edit them, then turn Live analysis off. The reference-video group can stay on to supply the original timing and audio. The manual fields remain available; you do not need to reload a saved analysis JSON for this route.

The analysis group also saves its results under output/scene_analysis/ for inspection or later reuse.

Reference images for native H3 scenes

Load Image Timeline provides one place to load, order and crop images to the shared canvas. Choose the assignment in Video loop · saved inputs + resume → reference_mode:

text_only — generate without using the loaded images.
first_only — use the first enabled image at the start of every clip.
last_only — use the last enabled image at the end of every clip.
first_and_last — use the first and last enabled images as endpoints. With one image, only the start is anchored.
first_per_scene — image 1 starts scene 1, image 2 starts scene 2, and so on. If there are more scenes than images, reuse the last image.
adjacent_pairs — scene 1 uses images 1→2, scene 2 uses 2→3, and so on. Once no next image remains, the last image supplies a start only.
reference_images — use up to nine visual references without fixing the opening or ending frame. Select a matching Ref2VA model; prompt tags such as <Picture 1> refer to enabled image order.

For three different scene starters, load three images, select first_per_scene, and define three scenes through cuts or scene prompts. Image slots do not create scene cuts by themselves. If one scene is split because of the render limit, its extra parts retain that scene's image assignment.

About fades: Image-timeline blending is not a crossfade between the final generated clips. The H3 assembly joins the planned parts. Lip-sync warmup helps prepare the next part; it is not a visible dissolve. This workflow does not provide a final clip-crossfade control.

Audio selection and timing

The shared audio choice follows this priority:

Audio override — an explicitly selected recording, or audio supplied by an enabled music-generation group.
Reference-video audio — when no override is supplied and the selected video has usable, unmuted audio.
H3-generated audio — in Native H3 when neither source supplies a recording.

A reference video without audio can still supply the duration and scene timing. With neither audio nor a video, Native H3 uses the planner's Duration. A silent but present audio track still counts as supplied audio; mute that source if you want H3-generated sound instead.

Lip-sync needs a recording and reference image. LS vocal isolation can guide the performance with separated vocals while keeping the selected full recording as the final soundtrack.

When using reference cuts with a separate audio file, align their excerpts yourself. Cut times are relative to the selected start; they are not automatically retimed to another song or tempo.

Optional music generation

Enable either YuE2 or MiniMax Music 3 when you want to create the recording first. Enable Audio override and set the full-song Load Audio source to Auto to receive generated audio. For your own recording, use Selected file instead. Keep only your intended generator active so the audio source is unambiguous.

YuE2

Select the YuE2 checkpoint. With Auto Prompt off, write musical direction in Style and the sung words in Lyrics. With Auto Prompt on, describe the song in Smart LM; its selected text supplies the generator instead of those manual fields.

Enable ABC planning adds a musical-score planning pass before music generation. Smart LM prepares the style and lyrics; YuE2's native ABC generator creates the score. Leave both native generators in full mode for a normal song test.

The saved generation duration is 360 seconds. Lower it for testing. The group saves the full song as FLAC; the shared audio controls then select the excerpt for H3.

MiniMax Music 3

Choose its model, text encoder and audio VAE. With Auto Prompt off, use Caption for musical direction and Lyrics for sung text. With it on, edit the Smart LM request instead. The saved duration is 120 seconds; lower it for a short test. This group also saves its full song as FLAC before the H3 excerpt is selected.

Time-saving tip: Reduce the music generator's duration when testing. Selecting a short H3 excerpt afterward still requires generating the full requested song first.

Optional lyrics and captions

Enable lyric extraction when you need to transcribe an existing recording. Review the transcript and correct the wording before using it as lyrics. For generated songs, the generator's selected lyrics can supply the caption text; manual full-song lyrics and correction fields are also available.

Automatic transcription and lyric alignment use the local Whisper large-v3 conversion. Download these five files from the supported Systran revision into ComfyUI/models/whisper/large-v3/:

model.bin
config.json
tokenizer.json
vocabulary.json
preprocessor_config.json

These files are checked against that revision. The saved timing option also uses Qwen3 · compare only, an optional alignment comparison. It needs Eclipse's additional Qwen dependencies and model setup; select Whisper for a first test without that extra pass. Follow the lyric-caption setup guide for installation details.

Enable lyric captions, choose a font and adjust the style. Review Caption alignment report, Clip-relative SRT, Full-song timing JSON and Cleaned lyrics. If a word was not aligned, check the report before adjusting its timing manually.

The run saves the complete caption recording and the selected excerpt start. Captions use that saved pair, so changing the current source controls cannot trim a loaded run again. With H3-generated sound, the workflow reads the audio from the assembled video; transcription then waits until that sound is available. Demucs is optional.

Use Load saved run while changing caption appearance or re-exporting an already generated video. Leave captions off for a clean video. Older runs saved before caption recording/offset support use their saved soundtrack from zero; any manual timing JSON for those runs must match that recording.

Common fixes

The wrong model runs after switching mode: select the matching loader preset and the separate LoRA preset as well as the generation path.
A downloaded file still appears missing: select its real local filename. Provider names and your example subfolders can differ; a browser reload also clears pending automatic download assignments.
The first scene keeps repeating: check the selected first/next prompt previews. Each next scene needs its own nonempty line, and Live analysis overrides the manual source while enabled.
Clothing from the reference video appears: use Scene Motion Analysis plus Exclude source appearance, inspect the generated prose, and edit manually if needed. Check that your intended reference-image mode is enabled.
Smart LM returns incomplete JSON: increase Max tokens, particularly with Thinking enabled. Thinking and the final answer share that allowance. Fewer frames or a smaller longest side can reduce input memory use.
The run list is empty: generate with Disk + Keep in output, then Refresh runs. Keep the complete saved folder under ComfyUI output.
Resume makes no new video: a completed run with Restart part 0 is already finished. Set the part number to replace, or select an unfinished run.
A replacement looks the same: change Render seed before queueing; changing it during execution does not change that queued job.
Prompt edits do not affect Resume: it restores the saved inputs. Start a New run to use a changed plan or different prompts.
Memory runs out: use Disk, reduce generation resolution, and keep analysis windows bounded. Disk storage reduces accumulated decoded-frame memory; it does not remove the model's own VRAM requirements.
