MiniMax H3高级配置·基础生成（Tlant）

Every video starts with the boring, load-bearing decisions: how long, what shape, what vibe. MiniMax H3高级配置·基础生成（Tlant） is where you make those in the Tlant MiniMax H3 family - the "basic generation" category of the advanced workflow, one of six config nodes that feed the Advanced Assembler.

Quick orientation: this node alone does nothing visible. It emits a typed config (基础生成配置) that only plugs into the Advanced Assembler's matching input. The assembler merges all six categories into a stateless English instruction for a remote LLM, which then writes your actual MiniMax H3 prompt. Leave this category unconnected and the assembler fills it with seed-stable random values instead - which is a fine way to work if you only care about, say, identity and camera. Connect it when the fundamentals matter to you.

The inputs, and which actually matter:

• 视频时长 - 4 to 15 seconds, MiniMax H3's official range. Worth setting deliberately; the instruction enforces that every cut and action fits inside it.
• 画面比例 - defaults to 跟随原图 (follow the source image). For image-to-video that default is usually right; the others are 21:9, 16:9, 4:3, 1:1, 3:4, 9:16, or a seed-rolled random pick.
• 主题预设 - the genre: dance, music video, TikTok-style, fashion editorial, cyberpunk, documentary, and a couple dozen more. The hover tooltips translate each to its English meaning.
• 自定义主题 - free text like "dark electronic club performance." The moment this is non-empty it completely overrides the theme preset - no merging, no appending. This is the escape hatch for every theme the preset list doesn't cover.
• 创意幅度 - conservative to wild; how far the video may drift from the static frame without breaking identity.
• 生成策略 - the stability-versus-diversity tradeoff (stable-first, balanced, diversity-first, or "bold experiments").
• 提示词详细度 - how dense the final H3 prompt should be (standard, detailed, very detailed).

Output: 基础生成配置, a custom typed port that refuses to plug into anything but the assembler. Chinese UI throughout, English output.

Gotchas

The one that bites: if you set a 自定义主题, don't also spend time fine-tuning the preset - it's ignored. And if you plug this into the wrong assembler slot, the connection simply won't take, which is the custom port type doing its job. Everything else is forgiving: any option you leave on its default either does the sensible thing or gets randomized reproducibly by the assembler's seed.
