| Use Video | BOOLEAN | true | ON = v2v: the video is loaded and is the reference for megapixels/width/height. OFF = i2v: no frames are loaded, the Picture_1 input is the reference. Exception: with Choose Audio latent = Audio From Video, a selected Video File still supplies its soundtrack (audio only). Set Video File to None for silence. |
| Video File | COMBO | None | 1 options: None |
| Choose Audio latent | COMBO | Custom Audio | Where the sound of the clip comes from. MiniMax Audio = like the official MiniMax H3 ref2v template: no bypass, the model's own audio latent goes to the sampler and the model generates the sound itself (voice, effects, music). A Custom Audio File / video soundtrack, if any, is then only sent as a reference (use <Audio 1> in the prompt). Audio From Video = the video soundtrack is encoded into the audio latent and frozen (silence if none). Custom Audio = the Custom Audio File is encoded into the audio latent and frozen (silence if none): the model never invents sound, the picture follows your music. Custom Audio also decides which audio Next Segment On Run moves through: the song is cut into chunks as long as the real video segment (frames / fps: duration 5 s = 124 frames = 5.17 s), one chunk per Run (works with Use Video OFF too); the segment counter at the top of the node decides which chunk is next (Jump). |
| Custom Audio File | COMBO | | 1 options: None |
| Audio Stem | COMBO | Full | Which part of the Custom Audio File is used. Full = the whole mix. Vocals / Guitars / Drums / Bass = only that stem (Guitars is Demucs' 'other' stem: guitars + keys + synths). The first time a stem is chosen for a NEW song, Hybrid Demucs separates all four (about 13 s for a 2 minute song) and saves them to output/<Song>/stems/<Song>_<Stem>.wav. After that every Run just reads the file. Needs a Custom Audio File. |
| megapixels | FLOAT | 0.20.1–1 | Target size. Use Video ON: the video sets the aspect ratio and width/height. Use Video OFF: Picture_1 does. The other pictures always keep their own aspect ratio. |
| duration | FLOAT | 5.00–10000 | Duration in seconds. Also sets the video segment length when Use Video is ON. durationS = this value unchanged; durationF = Minimax frame count. |
| Next Segment On Run | BOOLEAN | false | ON: every Run moves on to the next segment (video frames, and/or the custom audio chunk when Choose Audio latent = Custom Audio). OFF: the same segment on every Run: the first one, or the one you chose with Go in the panel (the counter does not move). |
| prompt | STRING | | MTV_Prompt: the prompt, e.g. the output of the IronLeo78-MTV-Omni-Prompt-Generator. Refer to references as <Picture i> (the connected Picture_n inputs) / <Video 1> / <Audio j>. Numbers count only what is actually sent: an empty picture slot is skipped (Picture_1 + Picture_3 connected = <Picture 1> and <Picture 2>). Audio order: video soundtrack first (if any), then custom audio. The status output lists the exact mapping. |
| Guide | BOOLEAN | false | OFF by default (v0.6.2). Only works with Next Segment On Run = ON. ON: the last frame of the previous run is used as a guide for the first frame of this segment, so the clips continue each other. The first segment (or a run with no saved frame from the segment before) runs without a guide. OFF: no guide. |
| Save Latent | BOOLEAN | false | OFF by default (v0.6.2). ON: the sampled latent (video + audio .latent files) and the conditioning (.conditioning: prompt + pictures, no guide) are saved in the song folder, named like the clip (see the filename output), so you can refine / upscale it later in another workflow. OFF: no latent files. (The clip itself is saved by the Save Video node you link.) |
| Latent overlap | BOOLEAN | false | EXPERIMENTAL, OFF by default. ON: the last seconds of the loaded video (Use Video ON) are pinned inside the sampled latent (latent noise mask), so the new clip really continues them: same pixels, motion and speed across the cut. The clip is sampled with the overlap in front and the overlap is cut off again, so each clip costs about 40 % more sampling. Needs Use Video ON and Choose Audio latent = Custom Audio with a song (the song then also covers the overlap). Replaces Guide for this clip; Save Latent is skipped (the saved latent would not match the clip). |
| Overlap (s) | FLOAT | 2.01–4 | Latent overlap: how many seconds at the end of the loaded video are pinned (rounded up to the model's frame rule). 2 s is enough. |
| LTX Continue | BOOLEAN | false | OFF by default. ON: after the clip is made, LTX 2.5 extends it by about 20 s in the same Run (whole segments, so the next Run starts where the extension ends). The last 49 frames of the clip start the LTX pass, the Huihui LLM writes the LTX prompt from your prompt and the last frame. A song (Custom Audio) or a video soundtrack (Audio From Video) goes through RAW for the whole clip and also guides LTX; with MiniMax Audio, H3 and LTX each keep their own sound. Needs the LTX files of the IronLeo78 LTV node. If the extension fails the H3 clip is kept. |
| modelsopt | IRONLEO78_MTV_MODELS | | Optional. Plug in the IronLeo78 MTV Omni Model Loader to replace the hardcoded diffusion model, custom LoRAs, text encoder, VAEs and step counts. Nothing connected = the hardcoded defaults. |
| Picturesopt | IRONLEO78_PICTURES | | Optional. All nine reference pictures on one wire: connect the IronLeo78-MTV-Omni-Prompt-Generator's Pictures output. Empty slots are skipped (the <Picture n> numbers count only the filled ones). |
