MiniMax H3 Lightx2v 4Steps LoRAでさらに爆速

いやはや、どこまで速くなる。

MiniMax H3の4steps LoRAを試してみました。

うちの環境は4060ti16GBとRAM32GBです。

これです。

２種類あって、

ですが、違いはよくわかりません。下のほうが圧倒的にサイズが小さいのでそれでいいかなって感じです。

FL2Vってなってるけど、R2Vで試してみます。

R2VのワークフローにLoad LoRAノードを追加します。

SageAttention + Sol_Attn + EasyCache の前に「Load LoRA」のノードを挿入しました。

Strength は0.75です。

モデルカードには、

と書いてあるので、場合によってはもっと落とせってことでしょう。

次に、Samplerは、「er_sde」か「sa_solver」を使うようですが、er_sdeだとセリフがよく破綻したので、sa_solverの方が良さそうです。

ステップは4です。あとはそのままです。

今回は、このストーリーボードでやってみます。ChatGPT-Image2.0で書いたものです。

これをプロンプトガイドを置いたChatGPTのプロジェクトでプロンプトを生成します。

subject_definitions:
<Subject 1> is Honeybee as depicted in <Picture 1>, a beautiful cybernetic bee-themed female combatant with very long blonde twin-tail hair, vivid pink-red eyes, black-and-gold biomechanical armor, horn-like black-and-gold head ornaments, translucent segmented insect wings with amber-violet iridescence, and glowing orange-gold energy accents.
<Subject 2> is Honeybee's swarm of small black-and-gold bee drones shown throughout <Picture 1>, each with a compact mechanical body, glowing amber core, and rapidly moving wing-like appendages.
<Subject 3> is the pheromone-energy effect shown in <Picture 1>, consisting of luminous amber-gold particles, flowing ribbons of light, circular trails, expanding honeycomb patterns, and an increasingly dense glowing field centered on Honeybee.
<Picture 1> is the four-panel storyboard reference for the target video, defining the chronological progression of Honeybee's pheromone dance, her poses and rotation, the drone choreography, camera framing, dialogue moment, and the final queen-like composition.

summary:
[reference generation] The target is a continuous approximately 5-second cinematic sequence based on the four-panel progression of <Picture 1>. <Subject 1> begins with her arms spread as <Subject 2> forms around her, then performs one elegant full-body rotation while swaying her torso, shoulders, hips, arms, and fingers in a seductive but controlled dance. <Subject 3> intensifies around her during the turn. The camera moves into a close-up as she finishes the rotation and says, <d>[Japanese] 甘美な毒に、抗えるかしら？</d>, before pulling back to reveal the completed glowing pheromone field and drone formation.

retention_analysis:
<Subject 1> (appears throughout): fully_preserved - Honeybee's blonde twin tails, pink-red eyes, black-and-gold biomechanical armor, head ornaments, translucent insect wings, feminine silhouette, and elegant queen-like demeanor remain consistent with the storyboard.
<Subject 2> (appears throughout): fully_preserved - the black-and-gold bee drones with glowing amber cores remain synchronized with Honeybee and form circular and spiral flight patterns around her.
<Subject 3> (appears throughout): fully_preserved - the amber-gold particles, flowing energy ribbons, circular light trails, and honeycomb field progressively intensify during the dance.
<Picture 1> ([Shot 1]-[Shot 4] storyboard structure): fully_preserved - the four storyboard panels determine the progression from opening pose, through rotational dance, to close-up dialogue, and finally the wide queen-like completion pose.

detailed_description:
The target video uses a dark, luxurious sci-fi anime aesthetic dominated by black and luminous amber-gold light. Motion is fluid, elegant, hypnotic, and continuous, with Honeybee's dance reading as one uninterrupted choreographed movement rather than four disconnected poses.

[Shot 1] <Subject 1> stands centered in a medium frontal composition against a dark futuristic environment. Her translucent wings shimmer behind her with subtle amber and violet reflections. She slowly spreads both arms outward while gently swaying her shoulders and hips, beginning the pheromone dance. Her wrists relax and her fingers extend elegantly. <Subject 2> rises around her almost simultaneously and begins forming a loose circular formation. Tiny amber particles from <Subject 3> appear in the surrounding darkness. The camera holds nearly still with a very subtle forward drift.

[Shot 2] At 00:01.200, without interrupting the motion, <Subject 1> transitions into one graceful full-body rotation. She turns smoothly through approximately 360 degrees while continuing to sway her torso and hips. Her arms sweep around her body in flowing arcs, wrists rotating and fingers tracing delicate patterns through the air. Her long twin tails and translucent wings follow the rotational momentum with believable secondary motion. The camera performs a gentle orbit in the opposite direction, emphasizing the turn. <Subject 2> spirals around her and leaves luminous circular trajectories. <Subject 3> expands into multiple concentric amber-gold rings and faint honeycomb geometry.

[Shot 3] At 00:02.700, as <Subject 1> completes the rotation, the camera rapidly but smoothly pushes into a close-up. A bright ribbon of pheromone energy sweeps across the foreground. Honeybee turns her face back toward the camera, her pink-red eyes locking directly onto the viewer. She gives a subtle, confident smile while her body continues a gentle residual sway. <Subject 1> (S1) speaks in a soft, alluring, self-assured Japanese female voice, <d>[Japanese] 甘美な毒に、抗えるかしら？</d> The surrounding golden particles become denser and the pheromone field visibly pulses outward.

[Shot 4] At 00:04.000, the camera rapidly pulls back into a dramatic wide-angle frontal view. <Subject 1> opens both arms fully and spreads her translucent wings into a majestic symmetrical display. <Subject 2> locks into an organized circular formation around her while <Subject 3> erupts into a large radiant amber-gold honeycomb field and luminous halo behind her. Energy ribbons spiral outward and glowing particles fill the air. Honeybee remains perfectly centered as the queen-like focal point while the final pheromone wave expands toward the edges of the frame. Hold the completed composition briefly through the final frame.

overall_soundscape:
Soft mechanical wing buzzing from the bee drones surrounds Honeybee throughout the sequence. Delicate crystalline energy tones accompany the pheromone particles, followed by layered sweeping sounds during the rotation and a deeper resonant pulse when the final honeycomb field expands. Honeybee's spoken line remains clear and foregrounded over the effects.

non_diegetic_music:
Dark, sensual futuristic electronic music at a moderate tempo, beginning with a restrained pulsing synth texture and gradually adding shimmering high-frequency tones during the rotation. The music swells subtly during the close-up dialogue and reaches a short, powerful luminous accent as the final pheromone field opens.

では、いってみよう。

速い。1分49秒。

MiniMax H3を初めて触ったときに15分以上かかっていたのは何だったのか。

で、できた画像がこちらです。

じゃっかんセリフがあやしいですが、十分でしょう。

ちなみに、4Steps LoRAを使わずに20Stepsでもやってみました。

3分20秒です。

EasyCacheのログが表示されていて、

となっています。よく効いてます。

4Stepsのときは、さすがに効果なしでした。

20Stepsの動画がこちら。

声の調子はガチャですね。プロンプトには、

となっているので、これに従っているようです。

では、もっとセリフも増やして10秒でやってみよう。

プロンプトは、

subject_definitions:
<Subject 1> is Reina in the reference storyboard, a silver-haired female combat android wearing sleek white, black, and metallic armor with luminous blue accents, sharp blue eyes, wing-like mechanical structures, and a bright blue energy blade.
<Subject 2> is Honeybee in the reference storyboard, a blonde female combat android with a high ponytail, black-and-gold segmented armor, glowing amber energy patterns, insect-like golden energy wings, and a long amber stinger-lance.
<Subject 3> is the ruined nighttime cyberpunk battlefield in the reference storyboard, with rain-slick broken pavement, rubble, distant neon skyscrapers, drifting sparks, smoke, and hovering combat drones.
<Picture 1> is the four-panel storyboard reference defining the confrontation, Reina's interrogation close-up, Honeybee's provocative response close-up, and the final return to a two-character battle stance.

summary:
[reference generation] Create a 10-second cinematic anime-style confrontation following <Picture 1>. <Subject 1> and <Subject 2> face each other in <Subject 3>. Reina demands information about Honeybee's plan, Honeybee refuses with a confident taunt, and both fighters raise their weapons as the confrontation turns into the opening instant of combat.

retention_analysis:
<Subject 1> (appears in [Shot 1], [Shot 2], [Shot 4]): fully_preserved - Reina's silver hair, blue eyes, white-black armor, blue luminous details, mechanical wing structures, and blue energy blade remain consistent.
<Subject 2> (appears in [Shot 1], [Shot 3], [Shot 4]): fully_preserved - Honeybee's blonde ponytail, black-and-gold armor, amber energy effects, insect-like wings, and stinger-lance remain consistent.
<Subject 3> (appears throughout): fully_preserved - the dark ruined neon city, wet ground, rubble, sparks, smoke, and surrounding drones remain the continuous battlefield environment.
<Picture 1> ([Shot 1]-[Shot 4] storyboard structure): fully_preserved - the four-panel progression and opposing character compositions define the shot order and dramatic escalation.

detailed_description:
The target video uses a high-detail cinematic anime action style with cold blue light around Reina opposed by warm amber light around Honeybee. Rain, sparks, glowing weapons, wet reflections, and shallow depth of field create an intensely charged nighttime atmosphere.

[Shot 1] A wide low-angle two-shot opens on <Subject 3>. <Subject 1> stands on the left with her body angled toward <Subject 2>, her long silver hair and mechanical wing structures moving subtly in the wind. Her blue energy blade points diagonally toward the wet pavement. <Subject 2> stands several meters away on the right, relaxed but ready, holding her amber stinger-lance low beside her body. Golden insect-like energy wings shimmer behind her. Small combat drones hover around both fighters while sparks and glowing debris drift through the rain. The camera slowly pushes forward between them.

[Shot 2] At 00:01.000, cut sharply to an intense close-up of <Subject 1> (S1). Reina raises her glowing blue blade toward the foreground, its luminous edge sweeping close past the camera and producing a strong blue flare. Her blue eyes lock directly onto Honeybee beyond the lens. With controlled anger she says, <d>[Japanese] あなたたちの計画は何か、私に話してもらうわ。</d> Her hair shifts across her face as blue energy pulses along her armor.

[Shot 3] At 00:03.500, cut to a medium close-up of <Subject 2> (S2). Honeybee tilts her head slightly, folds one arm loosely across her body, and gives Reina an amused, provocative smile. Amber energy crawls like luminous honeycomb veins across her black-and-gold armor and wings. A hovering drone drifts into the blurred background. She answers calmly, <d>[Japanese] ふふっ…そんな簡単に教えるとでも思った？</d> Her smile widens as her right hand tightens around the lance.

[Shot 4] At 00:06.000, cut back to a wide confrontation matching the final panel of <Picture 1>. Reina snaps her blue blade into a forward fighting guard while Honeybee lowers her center of gravity and brings the amber lance forward. <Subject 1> (S1) says, <d>[Japanese] ならば、力ずくで聞き出すまで。</d> <Subject 2> (S2) immediately replies, <d>[Japanese] それも面白い。やってみなさいよ。</d> Blue and amber energy rapidly intensify around them. The camera performs a fast accelerating push-in as both fighters suddenly launch forward. Their weapons swing toward each other and the video ends at the instant the blue blade and amber lance collide in a violent burst of blue-gold sparks.

overall_soundscape:
Steady rainfall, distant futuristic-city ambience, electrical drone hums, wind through rubble, sizzling energy weapons, armor movement, and drifting sparks. The final weapon collision produces a sharp metallic-energy impact followed by a powerful electrical crack.

non_diegetic_music:
Dark cinematic electronic-orchestral tension music begins quietly with low synth pulses and sustained strings, builds beneath the dialogue, then accelerates with heavy percussion during the final three seconds and peaks exactly at the weapon collision.

まずは20Stepsから。参照画像はこのストーリーボードのみにした。

どうかな。

7分15秒。5秒の倍以上かかった。

できた画像がこちら。

20Stepsでも途中のセリフがあやしい。

では、4Stepsでいってみよう。

速っ。2分31秒。

5秒に対しては、1.4倍くらいでできてる。

できた動画はこちら。

最後のセリフだけつぶれたけど、まぁ上出来です。しかし、10秒が2分31秒って。

このあと、12秒の動画に挑戦したら、VAE Decodeで落ちました。OOMです。RAM32GBの限界かな。

今後、メモリ不足に優しいノードが出てくることに期待です。

ではまた。
