+# MiniMax H3 Contex Loop 3070 Compact 30s
+
+## Summary
+
+Compact `MiniMax H3` imported-video extension master tuned around the smaller
+working stack Chris validated today.
+
+This variant keeps the `Contex Loop` existing-video flow, swaps in the lighter
+`w4a8` transformer and compact video VAE, points the stock source to `1.mp4`,
+and stretches the generated extension to `30` seconds total across two `15`
+second scenes.

+- `ethanfel/ComfyUI-MiniMaxH3-Contex-Loop`
+- `example_workflows/MiniMax H3 Extend Existing Video Model Workflow.json`

+- `minimax\\minimax_h3_fl2v_lightx2v_turbo_4step_v0.1_comfy.safetensors`
+
+## Main changes
+
+- set generated duration to `30s` total via two `15s` scenes
+- kept `5` step defaults for the compact stack
+- set source video to `1.mp4`
+- disabled source prepend so the extension target stays `30s`
+- kept `context_length=22`, `encode_mode=video`, `anchor_mode=head`
+
+## Notes
+
+- This is the saved repo version of the optimized flow.
+- For unattended queue testing, the live queued run uses the compact MiniMax
+  prompt graph directly so it can enter the Comfy queue immediately while other
+  jobs are still running.
