+# 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.
