VELVET VICE — MiniMax H3 I2V Studio · Native / GGUF · Audio · Vision Director

## v1.5.0 — Quality Refine, Re-Encode Refinement, Persistence &amp; UI Polish### New — Quality Refine / Second Sampler- Added an optional Quality Refine second sampling pass for improved sharpness, fine detail and overall image clarity- Quality Refine is integrated directly into the H3 System Hub- Added a dedicated ON / OFF switch- When disabled, the second sampler is completely bypassed and only the normal H3 sampling pass runs- Refine Steps are freely adjustable by the user- Added LIGHT, HIGH and CUSTOM refine modes- LIGHT uses a conservative <code>0.12</code> denoise preset- HIGH uses a stronger <code>0.20</code> denoise preset- CUSTOM allows manual denoise control from <code>0.01 – 0.35</code>- Added optional Preserve Base Audio to keep the original first-pass audio while refining the video latent- The second pass uses <code>res_multistep + simple</code>### New — Optional Decode → Upscale → Re-Encode Refinement- Added an optional Decode → Upscale → Re-Encode path before the second sampling pass- Allows the first-pass result to be decoded, resized and encoded back into the H3 latent before refinement- Upscale factor can be adjusted by the user- The H3 <code>[video, audio]</code> latent structure is rebuilt correctly before Pass 2- Audio can remain untouched through Preserve Base Audio### Improved Image Quality- Noticeably improved detail retention and clarity, especially at resolutions such as 720p- Reduced the soft / washed-out appearance that could remain after the primary H3 sampling pass- Fine structures, textures and edges remain more defined- Refine remains optional so users can choose between maximum speed and additional quality### H3 Vision / Prompt Director- Fixed the Prompt Director mode resetting to MANUAL after switching between workflows- Selected modes such as STANDARD VISION, ADULT ASSISTED and ADULT FULL AUTO now persist correctly### UI / Design- Restored a consistent Midnight Violet / Obsidian design across the H3 workflow- Removed unwanted green / teal execution coloring from node headers and status bars- Prevented dynamic render-state colors from breaking the unified Velvet Vice visual design- Quality Refine controls are now part of the System Hub instead of appearing as a separate floating control node- Fixed manual resizing for DOM-based H3 control panels- H3 POWER LoRA AV can now be resized correctly using the visible bottom-right resize handle### Release Synchronization- Civitai workflow/package version: <code>v1.5.0</code>- GitHub package version: <code>v1.5.0</code>- Comfy Registry package version: <code>v1.5.0</code>- ZIP version, workflow version, GitHub version and Registry version are now fully synchronized- Canonical Registry / Manager package ID remains:<code>velvet-vice-minimax-h3</code>- Preserved Native / GGUF routing, H3 audio/video generation, Turbo / Distilled LoRA, Power LoRA AV, profiles, live preview, Temporal Anti-Ghost, RIFE interpolation, watermarking and finishing tools
