| description | The three-field MiniMax H3 contract the APNext H3 Prompt Writer nodes emit for T2VA, I2VA, FL2VA and L2VA - integrated_multimodal_description / overall_soundscape / non_diegetic_music, the exact first-frame, first-and-last-frame and last-frame alignment lines, how the node's image batch maps to first_frame and last_frame, and how each mode develops from or converges onto its keyframes. Load with h3-prompt-director whenever the task is not Ref2VA. |
H3 base format (T2VA / I2VA / FL2VA / L2VA)
This is what the APNext H3 Prompt Writer and APNext H3 Claude Code Writer nodes
expect back. The node splits the text on these three labels, so they must appear exactly
once, in this order, each followed by one blank line:
integrated_multimodal_description: [Shot 1] <style>, <one continuous timeline> ...
overall_soundscape: ...
non_diegetic_music: ...
The stated visual style opens [Shot 1] (the node names it, or asks you to choose one).
Alignment lines
T2VA begins directly with integrated_multimodal_description:. The other modes put one
alignment line first, then exactly one blank line, then the three fields. Copy the wording
character for character; only N (the number of the final shot) and S.SS (the duration,
two decimals) change.
I2VA:
For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced.
FL2VA:
How the reference pictures align with the target video — Picture 1 (from Shot 1) aligns with the 0.00-second mark of the target video; Picture 2 (from Shot N) aligns with the S.SS-second mark of the target video.
L2VA:
How the reference pictures align with the target video — <Picture 1> (from [Shot N]) aligns with the S.SS-second mark of the target video.
The node's own directive repeats the right line for the chosen task type; if it and this
file ever differ, follow the node.
How the node's images map
The node sends whatever was connected to its image socket as an ordered batch and hands
the same frames back out as first_frame and last_frame for the video node:
- I2VA - the image is
<Picture 1>, the exact opening frame. Preserve its identity,
clothing, colours, key objects and geography, then develop forward from it.
- L2VA - the image is
<Picture 1>, the exact final frame, and belongs to the last
shot. Infer a plausible earlier state, then a transition path, then a gradual convergence,
then land on the image.
- FL2VA - frame 0 of the batch is
<Picture 1> (opening), the last frame is
<Picture 2> (ending). Describe the change between them and land exactly on the ending.
- T2VA with an image attached - the image is visual context to describe from, not a
keyframe. No alignment line, no
<Picture N> labels.
Describe what you actually see in the frames: subject, wardrobe, colour, light direction,
objects, spatial layout. Do not paraphrase the user's idea back when the picture already
answers the question.
