Maestro v1.8.0 is Live! MiniMax-H3 Sol Engine Speed ups & LTX-2.5 Support!

v1.8.0 (2026-08-13)

LTX-2.5 and next-generation LTX workflows

• Added native local LTX-2.5 with synchronized audio. Distilled is enabled by default, while Dev and NVFP4 variants can be enabled in Settings.
• Added the official Distilled 8-step base pass, learned latent upscaling, and 3-step full-resolution refinement, with persistent model reuse for faster follow-up generations.
• Added first and last frames, timed frame injection, audio-driven video, control-video audio, native audio, and compatible LTX-2/2.3 LoRAs from the existing shared library.
• Added LTX-2.5 to compatible Director Music Video, Short Film, and seamless-generation workflows.
• Fixed LTX-2.5 LoRAs producing noise on INT8 ConvRot checkpoints and added a choice between the fast video decoder and optional NAD diffusion decoder.

LTX multi-window sequences

• Added one consistent Multi-window Sequence workflow to all LTX video models, with AI-planned or exact one-prompt-per-window manual modes.
• Added duration and window counts, early prompt validation, editable generated window prompts, and chronological prompt planning that advances the story instead of repeating it.
• Improved LTX-2.5 continuation so full motion and matching audio history cross each window boundary cleanly without distorted seams or a slowdown in camera movement.

Audio, saved settings, and performance runtime

• Fixed slowed-down generated audio across MiniMax H3 and LTX and repaired standalone soundtrack routing when loading older settings.
• Load Settings now restores LTX window choices and geometry plus H3 Turbo, Sol Engine, First Block Cache, text encoder, and their associated values.
• Made the tested Sol-capable Python 3.11 / PyTorch 2.10 / CUDA 13 environment the normal Install, Update, and Start runtime on compatible RTX 40- and 50-series systems, while retaining safe fallbacks.
• Reordered the Studio sidecar to Duration, inputs or Omni references, H3 Optimizations, then Multi-window Sequence.
