-Makes a canvas for outpainting: drag the edges out to add room around a picture. The Source list shows the picture under the pointer. The new area can be a solid color, the average color of the nearest edge, the edge pixels smeared outward, a blurred copy of the picture, or a mirror of it. The card also has a seam feather, a canvas multiple and a megapixel budget, and **Exact padding** opens one control per side. A budget of 0 keeps the picture's size, and anything higher resizes the picture before padding. A picture wired into `source_image` is padded instead of the chosen file.

+Applies one rotate, crop and pad to every frame of a trimmed clip.

While you drag a trim handle, the node shows the exact first or last frame the run keeps. The bright part of the selection is what gets output.
 
 Fill, feather and the resize budget sit on the node face, and a new clip keeps them. That matters for video outpainting, because the black, hard-edged canvas the model needs survives a source swap. A fresh Clip node starts with that canvas, and the editor's **Reset transform** goes back to it. **Frames for** trims the end to the frame count the next video model takes: LTX (8n+1) or Wan (4n+1). Tap a ratio to pad the clip to it; a new clip is padded to the lit ratio too. The padlock keeps the shape while you drag a handle.
 
 It returns the frames, mask, audio, frame count, fps, size, duration, a `stitcher`, and the chosen `original` frames before the transform. **Inpaint & Stitch** in the editor sets the protected source area and previews the blend. After a video outpaint, wire the stitcher straight into **Stitch Inpaint**, with no Crop For Inpaint in between. It works in chunks to keep memory down.
 
-**Fixed frames** sets an exact output length: 120 frames at 24 fps is five seconds. Drag either handle, or drag the highlighted band to move the whole window. Type the count, or link a frame count into `fixed_frames`. 0 turns the fixed length off. The frame limit still caps the length.
+**Length** sets a number of output frames from IN. Drag IN or the small middle grip to move the window; drag OUT or type the count to change its length. The count stays when you choose a new clip, but the source can end before it is reached. For an exact count, link `fixed_frames`: 120 frames at 24 fps is five seconds. A positive value overrides OUT/`end_frame`, Length, `frame_load_cap` and Frames for; 0 turns it off. The source must be long enough, and IN can move earlier near the end so the window fits.

+Draw boxes on a canvas and say what goes in each one: a thing, or words to write in the picture. Wire `elements` to MOSS-Image Layout Prompt and the picture puts each thing where its box is. It shares the `background`, `bboxes`, `width` and `height` inputs with ComfyUI's own Create Bounding Boxes. For the same boxes, its first three outputs match, with `mask` added after them. It saves its boxes in its own `layout` text, and its canvas also works in the classic node look.
 
 Drag to draw a box, drag it to move it and its handles to size it; under the canvas each box gets **object** or **text**, its words and up to five colors. A picture on `background` shows under the boxes and sets the canvas size, `width` and `height` can come from Latent Size, and boxes on the `bboxes` wire fill the canvas when the workflow runs. **Grid** snaps the boxes as you drag them, starts off over a picture and takes its size from the gear, **Layouts** starts from a ready arrangement, the arrow keys move the chosen box one pixel at a time (ten with Shift), and Delete and Ctrl + D remove and copy it.
