ComfyUI-AusBoss is a curated collection of polished nodes designed to streamline the ComfyUI workflows I use most. Each node replaces repetitive setup with focused controls, compact graph footprints, and only the outputs needed downstream. Larger visual tasks open into dedicated full-screen editors, while experiments and one-off utilities stay out of the public pack.

Nodes

Image Crop + Rotate + Pad (AusBoss)

A Load Image-style node with a compact transformed preview and a full-screen editor for precise crop, rotation, padding, fill, mask feathering, and output-size alignment.

Video Crop + Rotate + Pad (AusBoss)

Targets an exact video frame from an uploaded input file or local path. The full-screen editor adds a long timeline, playback, exact frame steps, and the same transform controls as the image node.

Select Frame (AusBoss)

Returns one unchanged frame from an IMAGE batch using a clear one-based frame number. Out-of-range requests report the valid range instead of silently selecting the wrong image.

LaMa Inpaint (AusBoss)

Inpaints white mask regions with a TorchScript LaMa checkpoint, preserves pixels where the mask is zero, and processes large video batches one frame at a time to keep VRAM bounded. Place big-lama.pt in ComfyUI/models/lama/; the node never performs automatic downloads.

Load Video (AusBoss)

Loads a video as frames plus audio with frame_count, fps, width, height, and duration outputs. Its single responsive player includes a two-handle trim timeline: drag IN and OUT, preview exactly that window, and optionally loop it. Only the selected window is decoded. Optional custom width/height with aspect-preserving single-side mode.

Refine Mask (AusBoss)

Grows or shrinks a mask, optionally fills enclosed holes, and feathers the edge — returning both the refined mask and its inverse from one compact node.

Save Video (AusBoss)

Encodes frames to an H.264 mp4 with optional muxed audio and the workflow embedded, so saved files drag back into ComfyUI. The responsive in-node player previews the encoded result with loop and reload controls. Wire fps from Load Video to preserve source timing; audio and video land in a single file.

The two transform nodes return exactly:

image — transformed ComfyUI IMAGE
mask — generated-area MASK, including source transparency, rotation corners, and padding

The operation order is always rotate → crop → pad. New sources start with zero rotation, full crop, zero padding, and a canvas multiple of 1.

Install

cd ComfyUI/custom_nodes
git clone https://github.com/ausboss/ComfyUI-AusBoss.git

Restart ComfyUI, then search for AusBoss. There are no additional Python dependencies; the pack uses Pillow, NumPy, Torch, and PyAV already distributed with ComfyUI. LaMa Inpaint additionally needs a TorchScript big-lama.pt checkpoint in ComfyUI/models/lama/.

After updating frontend files, hard-refresh the browser with Ctrl+Shift+R.

Quick start

Add either transform node.
Pick or upload a source. For very large videos, switch the video node to local path mode. Queued workflows always read local paths, but the editor's live preview of paths outside ComfyUI's own folders is opt-in: start ComfyUI with AUSBOSS_TRANSFORM_LOCAL_PREVIEW=1 to enable it. This keeps the preview routes from exposing arbitrary files to anything that can reach your ComfyUI server (for example on --listen).
Click Open editor.
Drag cyan crop handles, orange padding handles, or the green rotation handle.
Close the editor and connect image and mask downstream.

Use the matching examples in example_workflows as small starting graphs.

Editor controls

Eight crop handles with generous hit targets
Four visually distinct padding handles
Rotation handle with alignment grid and Shift snapping to 15 degrees
Free or ratio-locked crop
Mouse-wheel zoom; middle-mouse or Alt-drag pan
Reset view, reset padding, and reset all
Video first/last, ±1, ±25, ±50, ±100, playback, and timeline scrubbing

Settings

Under Settings → 🆎 AusBoss you can pick an AusBoss node color scheme (Graphite, Slate, Teal, Moss, Plum, Rust, Navy). It recolors every AusBoss node in the open workflow immediately and applies to nodes you add later. Nodes you have colored by hand keep their own colors, and Theme default returns everything to the stock look.

Compatibility

Classic V1 node definitions for broad ComfyUI compatibility
Classic canvas and Nodes 2.0 frontend support
API-mode execution does not require the editor to be open
Transform editors validated on ComfyUI 0.27.1; the pack scaffold was also validated on 0.28.0

No minimum ComfyUI version is declared. If a frontend update changes custom-widget behavior, please include your ComfyUI and frontend versions in the issue.

Development

python scripts/validate_nodes.py
python -m unittest discover -s tests -p "test_*.py" -v
node --test tests/*.test.mjs

See AGENTS.md for compatibility rules and docs/adding_a_node.md for the node checklist.
