MiniMax H3 Extender 3070 R2V 480p 60s Clip By Clip

Summary

MiniMax H3 Extender tuned for a local-safe Ref2VA minute-long continuation path on Chris's box. This variant keeps the validated clip_by_clip extender model, uses the lighter local stack, and stretches the chain to 60s total as six 10s clips so each segment can be reviewed and validated before the next one runs.

Main changes

keeps clip_by_clip validation instead of full_batch
keeps the lighter 864x480 local-safe canvas
keeps 5 steps and the compact local stack
expands clips_json to six 10s continuation clips for a 60s total chain
keeps prompt structure continuity-first so each clip hands off cleanly

Notes

This is the minute-long direct successor to the current local-safe extender starter.
It is intended for progressive validation, not blind unattended full-chain trust.
Start by validating clip 1, then continue through the chain as each segment holds up.
