The important part is generating the correct conditionings:<pre><code></code></pre><pre><code>context_latents = [
 encoded_chunk,
 tail_latent,
]</code></pre>This approach leverages the native Bernini architecture instead of duplicating an entire sampler, making the package easier to maintain and fully compatible with existing Bernini workflows.An automatic chunk executor may be added in the future, but it would depend on the exact node names and class implementations installed on each user's system.<hr /><h1 id="acknowledgements">🙏 Acknowledgements</h1>Built on top of Kijai's work and the Bernini models.Many thanks to the original authors and the open-source community.<h1 id="license">📄 License</h1>Apache License 2.0.

Each tile size is calculated automatically and aligned to Wan's required multiple of 16. A 1×1 grid means the entire image is used with no splitting.Tile Select (Bruxos) — Extracts tile N (connect the For Loop index) while preserving all video frames, which is exactly what Wan expects.Tile Merge (Bruxos) — Stitches the tiles back together using feathered overlap (no visible seams) and automatically detects upscaling. If the processed tiles are returned at 2× the original size, the merged output is automatically 2× larger as well.Real-world examples using a 1920×1080 source (<code>tile_padding = 80</code>):GridTilesCalculated tile size1×111920×1088 — full image2×241120×7048×864400×30416×16256288×240Since 1080 is not a multiple of 16, Tile Split pads the canvas to 1088 by replicating the image borders, and Tile Merge crops it back to 1080. Without this padding, 8 rows of pixels would be lost. A complete round trip (Split → Merge) reconstructs the original source exactly.Tiles: Tile Split / Tile Select / Tile Merge — Split by tile count (2×2, 8×8, etc.) with automatic tile sizing aligned to multiples of 16, feathered stitching (no visible seams), and automatic upscale detection. These nodes replace the entire "Tile Settings" subgraph.0.19 — Pixel-based tiling: run the entire pipeline on each tile, with the source image/video cropped alongside it. Tile position is never lost because the tile's content is its position—the model sees "a complete small video" (its own corner of the original) and edits that video directly. No global RoPE misalignment.To address tile-to-tile drift (my other concern), I reimplemented live stitching: within the overlap region, each tile receives the already-generated output from its neighboring tiles (left, top, and top-left corner) composited onto the source, with the mask set to zero in that area. The model therefore treats those pixels as "already finished" and matches its output to them. I verified in testing that the composited overlap strip contains the neighbor's generated output, not the original source.<ul><li>Installer redesigned: includes Bernini-R INT8 ConvRot models and LightX2V 4-step LoRAs, automatic CUDA detection for onnxruntime-gpu, and idempotent downloads.</li><li>Bernini paper features: Bernini Prompt Enhancer (self-text CoT via local Qwen), First-Frame CoT (self vision-language reasoning), Bernini Multi-Guidance (Equations 8–12, experimental), and <code>guidance_mode</code> in Infinity.
