Maestro v1.6.0 is out! Major MiniMax H3 Improvements!

MiniMax H3 Omni Reference

Added MiniMax H3 Omni for generating new video and synchronized audio from ordered image, video, voice, motion, and sound references.
References can be reordered, labeled with their intended role, and used for identity, appearance, scene, motion, voice, performance, ambience, or music conditioning.
Added both recommended Pruned 20B and optional Full 33B Omni models.
Added Match Output reference preparation for consumer GPUs and an optional Maximum Detail mode for higher-memory systems.
Improved reference-video memory use with output-aware sizing, chunked projections, dedicated attention workspace, and safer model re-profiling.

Expanded H3 models and performance options

Simplified the model choices to First & Last and Omni, with clear Pruned 20B and Full 33B variants and concise explanations in the selector.
Added Full 33B support for both workflows, including ConvRot checkpoint loading, fused projection handling, and memory-efficient streaming.
Added selectable NVFP4-AWQ, GGUF Q2/Q4, Quanto INT8, and BF16 Qwen3-VL text encoders with hardware-aware recommendations.
Added support for the MiniMax H3 Turbo LoRA on compatible Full 33B models with true 4, 6, and 8-evaluation schedules.
Incompatible Turbo LoRA and Pruned-model combinations are rejected before loading instead of failing after a long generation.

H3 Studio workflow and prompting

Omni generations are limited to the native 345-frame maximum: 14.375 seconds at 24 FPS, displayed as 14.4 seconds, with sliding-window controls automatically hidden.
First & Last uses the same native 14.4-second maximum per window and can now generate longer videos by continuing each window from the preceding final frame.
Long First & Last runs preserve the requested duration, remove continuation overlap, keep synchronized audio aligned, and apply an optional end image only to the final window.
Fixed portrait and other selected aspect ratios being forced or decoded as 16:9.
Improved H3 Prompt Enhance for exact dialogue retention, stable speaker IDs, voice-reference intent, opening ambience, silent intervals, and reduced gibberish or invented speech.

MiniMax H3 in Director

Added model-aware Director workflows for both First & Last and Omni models.
First & Last can create prompt-only shots or use optional generated start/end frames, while Omni can condition shots on character, location, voice, video, soundtrack, and other project references.
Director no longer spends time writing or generating unused start images for H3 prompt-only workflows.
H3 shot prompts now carry the project world, location, wardrobe, character blocking, screen position, dialogue, soundscape, and continuity needed by independently generated clips.
Added stable project-wide speaker mapping, locked screenplay dialogue, duration-aware pacing, and multi-speaker exchanges with camera changes inside a single H3 clip.
Incomplete or altered local-LLM shot plans are repaired deterministically without silently truncating, moving, duplicating, or rewriting approved dialogue.
Dashboard repair and regeneration recreate the same H3 references and timing, including exact per-shot audio conditioning and one clean final soundtrack.

Compatibility and reliability

Director model lists now show only image and video models that support the selected automated workflow.
Native audio generation is distinguished from audio-reference input so incompatible models are no longer offered for audio-driven jobs.
Reduced console noise by hiding successful system-stat polling while retaining failures and meaningful API requests.
Interrupted saved Director jobs are now reported as interrupted instead of disappearing as missing projects.
Expanded automated coverage for H3 checkpoints, quantization, Omni reference packing, Turbo LoRA, Studio continuation, Director compatibility, dialogue planning, memory behavior, and UI contracts.
