GlennHasABeard fixes a reversed paw print in local MiniMax H3 clips
GlennHasABeard uses constrained prompts and locked cameras for local MiniMax H3 clips in ComfyUI. He reports fixing a reversed paw print, while generation takes about an hour per 15-second clip before Topaz upscaling.

TL;DR
- A local MiniMax H3 retake fixes a double tap and reversed paw print, according to GlennHasABeard's production notes.
- Locked framing limits the cat to ears and eyes in the box clip, reducing the anatomy the model has to maintain.
- Generation takes about an hour per 15 seconds in the creator's account; his clip notes specify local ComfyUI rendering followed by Topaz upscaling to 4K.
A marshmallow ghost succeeded where an earlier sheet-to-ghost attempt had only billowed. A spider dunked like a teabag initially went headfirst into the cup, then flipped underwater to climb out.
One press, one paw print
The first pie take touched down twice and left the print facing the wrong way. The gloriously fussy correction gets one touchdown and an impression aligned with the approaching paw, using a locked camera slightly above the pie.
The posted prompt excerpt: “leaves one clean paw print in the filling.”
The filling's displacement impressed the creator too.
Ears, tails and silhouettes
Three cat shots deliberately limit the details H3 has to maintain:
- Ears and eyes: Each box flap gets its own second and side in the box shot, with only ears and eyes emerging over the rim.
- Tail: A right-facing bag opening gives the tail a clear exit in the bag clip, shot side-on at floor height.
- Silhouette: Removing fur and facial detail lets the creator show a whole cat without a reference, as he explains in the moon clip.
Transformations in place
GlennHasABeard repeatedly specifies where a transformation originates:
- Soap curl → bat: The bat forms from the shaving on top of the block, with no new creature flying into frame, according to the soap-cutting thread.
- Marshmallow → ghost: The change stays on the skewer in the roasting test.
- Orange → jack-o'-lantern: The tiny pumpkin occupies the fruit's original position in the peeling clip.
- Leaf → moths: The prompt identifies the moths as the leaf itself, rather than insects arriving from elsewhere, in the leaf test.
Zippers, fog and body orientation
The motion notes constrain travel paths as well as transformations:
- Zipper direction: The zipper runs left to right across the pumpkin's front in the pumpkin reveal, giving the pull one route before the upper half opens like a lid.
- Opening direction: The left half moves left and the right half moves right in another fog clip, giving the vapor a single outlet along the fold.
- Material behavior: Describing fog as pouring “like milk” keeps it moving downward in the pouring test, although the pour still misses the bowl.
- Body orientation: The revised spider setup holds the animal head-up throughout, dipping only its back end into the water.
- Travel endpoint: The broom prompt specifies one long stroke across the porch and off its open end in the sweeping clip.
Counts still slip
The crow-and-pumpkin prompt asked for one tap and one answering knock. The render produced several taps and two knocks; GlennHasABeard wrote that H3 “still won't hold a count,” while accepting the exchange as a successful conversation.
About an hour per 15 seconds
GlennHasABeard reports roughly an hour of generation for a 15-second clip. He queues a week's worth of tests, lets them run, then picks the takes he likes best.
The timing reply gives no GPU model.
Weights, resolution and commercial rights
- Files: ComfyUI publishes native H3 workflow templates and repackaged model weights.
- Resolution: The official H3 model card specifies a default 768-pixel short edge at 24fps; the 4K delivery in GlennHasABeard's pie clip comes after the Topaz pass.
- Rights: Commercial use of locally generated outputs requires a MiniMax commercial license, according to ComfyUI's H3 guide; the guide says Comfy Cloud generations include commercial rights.
