# MiniMax H3 Turbo FP8 I2V
|
|
|
|
## Summary
|

|
|
|
- `minimax`
|

## Developer notes
|
|
|
|
- The graph runs the `MiniMaxH3ImageToVideo` node with optional first and last frames.
|
|
- It uses the same FP8 / NVFP4 / audio-VAE model stack as the t2v template.
|
|
- The workflow keeps the `17k+5` frame rule and exposes the keyframe inputs plainly.
|
|
|
|
## Our notes
|
|
|
|
- This is the most practically useful of the three templates for identity lock and frame-to-frame control.
|
|
- Good fit for reference-driven tests, but still a heavy ask on an `RTX 3070` with `8 GB` VRAM.
|
|
- Worth keeping next to the existing MiniMax first-frame and reference workflows.
|
|
|
|

- Best same-day MiniMax H3 import if you want a simple first/last-frame graph.
