Maestro v.1.7.0 - BIG UPDATE! Long multi-clip videos in FL & REF models

v1.7.0 (2026-08-10)

MiniMax H3 native multi-window generation

• Added native multi-window continuation to both First / Last and Omni, carrying recent motion and synchronized stereo audio into each following window for smoother transitions.
• Added shared Multi-window controls with total duration, editable per-window prompts, optional AI planning, and independent hard-cut sequences.
• Improved H3 sequence planning so actions, dialogue, camera cuts, sound, and story events advance across windows instead of repeating or finishing in the first clip.
• Added exact-duration assembly, model-aware overlap handling, and saved runtime prompts so long generations can be reviewed, edited, and reproduced.

New H3 media workflows

• Added multiple timed frame injection for First / Last generations.
• Added audio-driven video from an uploaded soundtrack or a control video's audio.
• Added video-to-audio generation that preserves the source pictures while creating a new synchronized soundtrack.
• Added H3 video-to-video editing for the whole frame, inside a mask, or outside a mask, with adjustable denoise and mask strength.
• Fixed Omni music and performance references restarting from the beginning in every sequence clip; each window now receives the correct timeline segment while voice references remain reusable.

Memory, performance, and RTX 50 support

• Added VRAM-, model-, and resolution-aware H3 window recommendations with a native 14.4-second ceiling and saveable user overrides for proven hardware combinations.
• Improved transformer residency, activation workspace, streaming VAE decoding, RAM budgeting, and LoRA fallback behavior for Full and Pruned H3 models.
• Added a dedicated RTX 50 / Blackwell runtime with Python 3.11, PyTorch 2.10, CUDA 13, compatible acceleration kernels, automatic migration, startup diagnostics, and one-click repair.
• Preserved the established runtime for RTX 20/30/40 systems while applying hardware-specific setup only where required.

Workflow and interface reliability

• Added early validation for incompatible H3 media, prompt counts, durations, and sequence settings before expensive model loading begins.
• Fixed Omni reference uploads on iPhone and iPad so supported audio files are selectable even when iOS reports unusual file types.
• Generation cards now show active generation time in minutes and seconds, excluding time spent waiting in the queue or loading models.
• Expanded regression coverage for H3 continuation, reference packing, audio timing, frame injection, video editing, memory recommendations, RTX 50 setup, and the shared multi-window interface.
