ComfyUI Node
[Legacy] H3 Continuum Sampler V3.2.4
Production H3 Continuum sampler with first/last-frame or image-reference conditioning and ComfyUI-native advanced widgets. Video/audio VAE decoding remains in ComfyUI Core.

Inputs (31)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | — | |
| clip | CLIP | — | |
| video_vae | VAE | Used only to encode image conditioning. T2VA does not use it; Continuum never decodes with it. | |
| sampler | SAMPLER | — | |
| sigmas | SIGMAS | — | |
| sequence_prompt | STRING | Connect one Text (Multiline) for the complete sequence. | |
| prompt_mode | COMBO | Auto | Auto accepts Fixed, list-separated, and timeline prompt styles. |
| chunks | INT | 31–16 | Number of sequential Continuum chunks to generate. |
| chunk_seconds | FLOAT | 5.04–15 | Target duration per chunk. Five seconds is the validated default. |
| width | INT | 134432–16384 | Output width. Use a multiple of 32. |
| height | INT | 76832–16384 | Output height. Use a multiple of 32. |
| continuity | COMBO | Balanced — 22 frames | Amount of prior video context retained at each chunk boundary. |
| base_seed | INT | 00–18446744073709550000 | Base seed used to derive deterministic per-chunk seeds. |
| audio_continuity | BOOLEAN | true | On passes prior audio context into continuation chunks. Turn it off only to isolate or replace generated audio. |
| diagnostics | COMBO | Basic | 3 options: Basic, Detailed Report, Off |
| reroll_from_chunk | COMBO | Auto | Auto resumes the longest compatible saved prefix. Choosing a chunk reuses earlier chunks and regenerates that chunk and everything after it. |
| reroll_nonce | INT | 00–4294967295 | Change only when regenerating an explicit chunk and you want a new variation with otherwise identical settings. |
| strict_compatibility | BOOLEAN | true | — |
| debug | BOOLEAN | false | — |
| show_preview | BOOLEAN | true | — |
| run_storage | COMBO | Off | Atomically save raw AV chunks and resume a compatible saved run. |
| run_name | STRING | Enter a stable name for this saved run. Compatible chunks are selected automatically. | |
| reference_size | COMBO | Match Output | Match Output is the practical default; Max Identity preserves more reference detail. |
| project_id | STRING | Optional. Leave blank to derive a stable ID from this sampler node. Run Name remains the explicit override. | |
| first_frameopt | IMAGE | Optional. Leave all image inputs disconnected for T2VA. | |
| last_frameopt | IMAGE | — | |
| reference_image_1opt | IMAGE | — | |
| reference_image_2opt | IMAGE | — | |
| reference_image_3opt | IMAGE | — | |
| reference_audio_1opt | AUDIO | — | |
| reference_audio_vaeopt | VAE | — |
