GlennHasABeard tests directional prompts with local MiniMax H3

GlennHasABeard’s local MiniMax H3 tests replace a failed block-collapse prompt with sideways sliding and give growing lace a directional path. He reports roughly 50 minutes per clip in ComfyUI.

TL;DR

A cat stays offscreen throughout the purring-box clip. A comb turns marbling into a galaxy in another experiment, with an explicit instruction against muddy water. ComfyUI’s H3 documentation also describes native stereo audio generated alongside the video.

Sideways blocks

GlennHasABeard says his first version collapsed a tower and asked every piece to land in order. His smartest revision kept the blocks supported and let them slide.

  • Prompt excerpt: “each block slides a short step to the right along the top of the block beneath it”
  • Camera: Locked, side view.
  • Timing: The tower becomes stairs in twelve seconds within a 15-second clip.

Amber lace

GlennHasABeard aligns the pitcher’s travel with the lace pattern’s growth, so the transformation follows one continuous direction.

  • Prompt excerpt: “it cools into a lacy amber pattern like frost on a window”
  • Camera: Locked, slightly above the tray.

A school of paper fish

Rather than specifying an exact fish count, GlennHasABeard uses “about a dozen” and “swimming together” in the paper-fish thread. His explanation: treating the school as one object helps it hold together.

  • Prompt excerpt: “a small school of folded paper fish swims out of it and circles the kitchen”
  • Camera: Locked, counter height.

Offscreen cats and clean marbling

  • Purring box: “a soft deep purr comes from inside it.” The governing rule is “No cat appears,” with the camera locked at rug height.
  • Marbling galaxy: “the pattern it pulls resolves into a spiral galaxy with a bright core.” GlennHasABeard adds “Never mixes into muddy water,” with a locked, top-down camera.

Lamp light and timed sound

GlennHasABeard also specifies which side of an object receives light and how sounds unfold within a shot.

  • Paper in orbit: “lit on the side facing the bulb and dark on the other side.” The desk lamp acts as the sun; six seconds of crinkling precede a hum. The camera stays locked at desk height.
  • Dessert skater: “a tiny ice skater in a red scarf glides slowly in wide circles.” Two cracks precede nine seconds of blade-on-ice sound, as he describes in the skater thread. The camera stays locked overhead.

RTX 3060 renders

GlennHasABeard renders the 15-second clips locally in ComfyUI and takes them to 4K with Topaz, as he describes in the lace post. His roughly 50-minute render report comes with these machine specifications:

  • GPU: NVIDIA GeForce RTX 3060, 12 GB.
  • CPU: Intel Core i7-8700K, 3.70 GHz.
  • RAM: 32 GB.

That reply does not specify the model variant or sampling settings. ComfyUI’s official workflow guide lists version 0.30.0 or later for native support.

Model downloads are packaged in Comfy-Org’s H3 repository, while MiniMax’s resource hub links local setup guides and hosted access.

Overnight queues and thumbnails

GlennHasABeard loads test prompts and leaves them running overnight and while he is at work, building up clips for weekday posts.

His thumbnail post also collects four illustrated designs for “The Scarves.”
