Inputs (13)
| Name | Type | Default | Description |
|---|---|---|---|
| clip | CLIP | — | |
| vae | VAE | — | |
| context_latent | LATENT | AV latent output from a prior MiniMax H3 generation to continue from | |
| prompt | STRING | — | |
| length | INT | 1245–3600 | New frame count at 24 fps for the continuation only (excludes context_frames) |
| context_frames | INT | 21–64 | Trailing latent frames of context_latent carried over as context |
| pin_last_frame | BOOLEAN | true | Decode context_latent's true trailing pixel frame and pin it as this call's frame 0. Ignored if first_frame is connected. |
| audio_vaeopt | VAE | — | |
| first_frameopt | IMAGE | Hard-pin this call's frame 0 to an exact image (e.g. the prior clip's real last output frame) instead of pin_last_frame's decode | |
| last_frameopt | IMAGE | Pin this continuation segment's own final frame to an exact image -- e.g. to land precisely on a known next shot/keyframe instead of leaving the ending fully generated. Not part of the native fork's VideoExtend node (which has no end-anchor at all); added here since it's a natural, low-risk extension of the same PackedLayout mechanism first_frame/context already use. | |
| ref_image_sizeopt | COMBO | match | 2 options: match, max |
| ref_imagesopt | IMAGE | Reference image(s) -- connect a batch (e.g. via ImageBatch) for more than one; each frame becomes its own <Picture i> reference. Not the native node's per-slot Autogrow inputs -- this is a single batched socket. | |
| ref_audioopt | AUDIO | One standalone reference audio clip |
