🎬 ABOUT THIS VIDEO

Tired of AI video drift, awkward cuts, and losing environment consistency between shots? In this tutorial, I’ll show you how to generate LONG, seamless MiniMax-H3 video continuations inside ComfyUI with 100% visual context consistency!

I built custom nodes specifically to solve the biggest problem in multi-shot AI filmmaking: quality degradation. Instead of re-encoding compressed MP4 files (which causes dark artifacts and generational loss), this workflow saves and chains the raw video latents directly—giving you seamless, continuous scenes without visual drift. In this video,

you'll learn:

✅ How to set up and prompt MiniMax-H3 using custom system prompts in Gemini

✅ The secret to chaining shots using saved latents (with zero quality loss)

✅ "Seed Video" vs. "Seed Ref Video" — how to maintain wide room layouts and subject positioning

✅ Pro-tips on subject weight balancing when introducing new characters

✅ Auto-trimming and stitching clips together into one continuous master take

✅ A quick sneak peek into the Version 2 one-shot pipeline I'm currently building! Both the custom nodes and complete workflow are 100% FREE to download
