MiniMax H3 Contex Loop 3070 Safe 60s AWQ INT8

Summary

Server-safe MiniMax H3 imported-video continuation workflow built from the successful local 1024x576 ref2v run and adapted back into the Contex Loop lane for unattended 60s generation.

This variant keeps the Contex Loop existing-video flow, but swaps to the proven INT8 base model, drops the Heretic text encoder, disables the failing MiniMaxH3MemoryEfficientSageAttentionPatch, and expands the continuation plan to 6 x 10s clips with review pauses disabled.

Status

• server-safe-loop-60s-test

Workflow asset

• workflow.json

Built from

• optimized/image-to-video/minimax-h3-contex-loop-3070-compact-prepend-480p-3x10s/
• successful ComfyUI run cc74efa5-1a53-4b2a-9d7c-7170ea7eba5b

Key model stack

• minimax_h3_ref2va_pruned_int8_convrot.safetensors
• qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors
• minimax_h3_video_vae_int8_convrot.safetensors
• minimax_h3_audio_vae_fp32.safetensors
• minimax\minimax_h3_ref2v_lightx2v_turbo_4step_v0.1_resized_avg_rank_20_bf16.safetensors

Main changes

• switches from the w4a8 loop stack to the successful int8 ref2v base
• replaces the Heretic encoder with qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors
• keeps SolAttn, but bypasses MiniMaxH3MemoryEfficientSageAttentionPatch because it crashes on the current server
• sets prepend_original=false so the assembled output is a generated 60s continuation rather than source-plus-extension
• disables the review gate for unattended queue runs
• expands the plan to 6 x 10s continuation shots with continuity-first handoff

Notes

• Queue with a real server-side source video override because the placeholder 1.mp4 is not present on the live ComfyUI box.
• This is intended as the first unattended minute-long loop test, not the final quality-maxed master.
