Dual Engine MiniMax-H3 + LTX-2.5

Summary

One ComfyUI graph with a switch between a continuous MiniMax-H3 chain and an LTX-2.5 scene pass. It is a useful compare-and-contrast workflow for deciding whether a shot wants one long take or an edited cut structure.

Developer notes

• The source README describes the graph as "one script, one switch".
• The MiniMax-H3 lane is for a single continuous take.
• The LTX-2.5 lane is for a scene that wants internal cuts.
• The source README points LTX-2.5 users to joeygambino/LTX-2.5-Quantized for the smaller builds.

Our notes

• This is the most interesting same-day hybrid workflow hit because it is not just another model dump.
• It is a better comparison tool than a first local run on an RTX 3070 / 8 GB; the full graph is more of a reference pack than a light test.
• If you want to judge H3 against LTX on grammar and continuity, this is the cleanest daily find.

Required custom nodes

• ComfyUI-H3-Multishot
• ComfyUI-Easy-Use
• ComfyUI-kjnodes
• ComfyUI-Impact-Pack
• ComfyUI-Ollama
• ComfyUI-GGUF if you use the quantized LTX lane
• RES4LYF

Required model files

• Comfy-Org/MiniMax-H3
• joeygambino/LTX-2.5-Quantized or an equivalent quantized LTX-2.5 build for the second lane

Notes

• Best treated as a benchmark pack for deciding which video grammar is worth pushing locally.
• The H3 lane is the more direct fit if you care about continuous takes.
