ComfyUI Node
Mpi Video Sampling Preview
Live RGB sampling previews for video models ComfyUI cannot preview. Formats like MiniMax H3's name no taesd decoder, so their previews fall back to blocky latent2rgb blobs. Wire a tiny TAEHV VAE (taeh3) into `vae` and this decodes the in-progress latent for real, streaming frames on the standard binary preview channel so a host app sees them with no extra plumbing. Sits anywhere on the model wire before the sampler; passes the model through untouched.

| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | — | |
| vae | VAE | A TINY TAEHV decoder, not the model's real VAE — taeh3 for MiniMax H3. Load it with MpiTinyVaeLoader: a plain VAELoader CANNOT build taeh3 (see that node). Handing over the full VAE here decodes at full cost every step and will crawl. | |
| preview_rate | FLOAT | 8.01–60 | Playback speed in frames per second, announced to the consumer with the clip. Every step decodes the whole clip (a temporal decoder cannot skip frames), so this paces playback, not cost. |
