MosaicDiff for Windows

Each H3 sample now uses a crop from the mosaic boxes in that sample. A close-up no longer stretches the crop for the whole file, so a wider shot is not repainted from a small patch.

The H3 worker uses ComfyUI's INT8 attention when Sage Attention is not installed, and releases leftover video memory between samples.

The detector still runs on the GPU. Unpack with 7-Zip and run MosaicDiff.exe.

Portable ComfyUI cannot build the nvidia-vfx source package because pip cannot import wheel_stub.buildapi. This build installs the binary wheel from NVIDIA's index.

The detector still runs on the GPU. Unpack with 7-Zip and run MosaicDiff.exe.

BasicVSR++ was dropping 4 frames at every 90-frame chunk. On a longer clip the H3 step then stopped with VSR video ended before H3 frame(s). This build keeps every frame.

The H3 worker now finds the context-window node that ships with MosaicDiff. Sage Attention is turned on only when that package is installed.

The detector still runs on the NVIDIA GPU. Unpack with 7-Zip and run MosaicDiff.exe.

MosaicDiff for Windows

The mosaic detector now runs on the NVIDIA GPU. The log should say Detector model on CUDAExecutionProvider.

v1.0.0 shipped the CPU-only ONNX Runtime, so detection stayed on the CPU and was very slow. This build uses onnxruntime-gpu 1.30.0 and the CUDA libraries already included with the program.

Unpack with 7-Zip and run MosaicDiff.exe. ComfyUI is still a separate install. BasicVSR++, Eros Max, the text encoder, and the video VAE still download on first Start.

MosaicDiff for Windows

Download MosaicDiff-windows.7z and open it with 7-Zip. Run MosaicDiff.exe.

ComfyUI has to be installed separately. The mosaic detector and the H3 LoRA are in this download. BasicVSR++, Eros Max, the text encoder, and the video VAE download the first time you press Start.
