Video Crop + Rotate + Pad -> Clip / -> Frame:
- The rail under the preview is a timeline: playhead scrubbing on the node
face, frame-accurate IN/OUT handles that carry the playhead, Set IN/OUT
and I/O keys in the editor; js/shared/timeline_math.mjs mirrors the
backend's inclusion rule and emits hundredth-grid seconds.
- Scrubbing no longer flickers: storyboard tiles only stand in when nearer
than the frame on stage and are decoded at their target times; the scrub
session returns the frame it already decoded instead of the next one;
served previews are cached.
- Aspect lock on the format chips (pad, lock, clear) with lockPadding in
transform_geometry; Lock aspect in the editor.
- A new source keeps fill, feather, resize, Snap and Limit and re-pads to
the lit chip; a canvas row (fill, feather, resize) sits on the node face.
- The clip node declares a black fill and feather 0 as its defaults and the
editor's Reset all follows the node's own declaration, so a fresh node or
a reset never lands on the grey, feathered canvas the LTX IC-LoRA cannot
paint; image nodes keep grey/24.
Examples:
- LTX 2.3 Video Outpaint: Select Frame -> core Generate Text writes the
positive prompt; note rewritten with the tested rules (53 renders over
six clips: only fill #000000 + feather 0 decide painting).
- Core model loaders coloured and Workflow Notes grown to fit across the
other examples.
- Optional resize of the transformed output to a pixel budget, with core
Scale Image to Total Pixels semantics: megapixels x 1024^2, aspect
preserved, each dimension rounded to resolution_steps. The image uses
the chosen filter (lanczos/area/bicubic/bilinear/nearest-exact); the
mask always resizes bilinear so feathered edges cannot ring. The math
is mirrored py+js (scale_to_megapixels / scaleToMegapixels) and
fixture-tested on both sides; the new widgets append after the stable
V1 set so saved workflows keep loading, and IS_CHANGED fingerprints
them.
- A quick row under the node's canvas: Reset (rotation, crop, padding),
a Feather toggle that remembers the amount it turns off, and the
Resize toggle with its megapixel scrub box.
- The editor gains a Resize output section (megapixels and steps as
scrub controls, method select) and its status names the exact resized
size.
- The output size readout moved off the pixels: centered below the image,
flipping above when clipped, and showing the resize target.
- CHANGELOG entries for this round and the two commits before it.
The audit compared every node against ComfyUI core and the major packs;
this lands its outcomes in one branch.
On-node visual editing (the old Codex-pack interaction, rebuilt):
- New Load Image + Pad: image loader with whole-edge pad dragging on the
node canvas, align-to-multiple rounding, and a megapixel target that
rescales the source before padding so the mask seam stays binary.
- Pad Image gains the same handle canvas, fed by an execution-time
snapshot of its input; wireframe with diagnostic empty states before
the first run. Widgets, outputs, and saved workflows unchanged.
- Image Crop + Rotate + Pad's compact panel is now a live stage - crop,
pad, and rotate handles on the node, one shared implementation with
the full-screen editor so the two surfaces cannot drift.
Feature gaps closed against the ecosystem:
- Crop For Inpaint: target_megapixels, selectable rescale_algorithm
(recorded in the stitcher for the paste-back), and extend_* inputs
that grow the frame itself for outpainting.
- Save Video: format choice - mp4 h264, mp4 h265, webm vp9 with Opus
(resampled to 48 kHz); CRF drives all three.
- Load Video: every_nth thinning (fps output divides to match) and a
max_frames cap that ends the decode early.
- LoRA Loader: saved stack templates behind a bar button, and a console
warning when a LoRA's base-model family disagrees with the checkpoint.
- LM Studio Chat: history in/out for multi-turn chains and a json_schema
widget for structured replies.
- Drop Shadow: multiply blend and a shadow_mask output. Align Image:
offset outputs for un-aligning after sampling. Color Match:
first_frame reference mode as a one-node video flicker fix.
Removed (backed up in git history): Select Frame Range and the Video
Bundle family - core ImageFromBatch and the core VIDEO wire now cover
both jobs. Dead NODE_ID module variables cleaned out of every node file.
455 Python tests, 216 JS tests, validate_nodes.py green on 19 node files.
The rotation knob previously anchored to axis-aligned bounding boxes, so
under rotation or padding it floated in space, visually attached to
nothing. It now rides the actual top-right corner of the rotated image
quad (short stem, offset outward along the corner's radial direction)
and orbits with the image as the angle changes - the grab-the-object's-
corner model design tools use. Verified at 0/30/-60/135 degrees: the
drawn knob sits exactly at the computed rotated-corner position.
Feather quality of life: default is now 24 (a no-op until padding or
rotation creates generated area), and the slider is paired with a number
box with single-step arrows for granular control; both stay in sync and
values above the slider range remain typeable up to 4096.
The sidebar Preview now renders the feather fade live: it builds the
generated-area mask (padding, rotation corners, source alpha), blurs it,
draws it twice to match the engine's edge-pinned ramp, tints it with the
fill color, and overlays - so tweaking feather shows the real blend as
you type. Verified: preview pixels near the crop edge move measurably
toward the fill color as feather increases.
Review fixes verified against live ComfyUI 0.28.0:
- rotatedSize now reproduces Pillow's expand=True output exactly (transpose
fast path at axis angles, corner extents elsewhere). The previous formula
was 1px short on 34 of 78 sampled size/angle combos, so editor-predicted
output dimensions disagreed with queued results at most free angles.
Verified 0 mismatches across 6776 combinations and end-to-end on the
server (predicted 848x496 == queued image and mask at 77.7 degrees).
- decode_video_frame seeks to the nearest keyframe and decodes forward
instead of scanning from frame 0, with the sequential scan kept as the
fallback for files without usable timestamps. Scrubbing long videos no
longer decodes the entire prefix per preview request.
- Preview routes no longer serve arbitrary local paths to any HTTP client:
local-path previews outside ComfyUI's input/output/temp folders now
require AUSBOSS_TRANSFORM_LOCAL_PREVIEW=1, checked before touching the
filesystem so denied requests cannot probe path existence. Queued
workflows are unaffected.
- Editor: metadata is cached per source instead of refetched every scrub
tick, timeline seeks fetch only the frame with a 70ms trailing debounce,
AbortError from superseded requests no longer paints the error state,
and switching source mode before picking a file no longer resets the
transform.
- Tests: 13 -> 18 Python (seek vs sequential ground truth, time-mode seek,
out-of-range clamp, preview gate), 8 -> 9 JS (Pillow-verified rotated-size
fixtures including the odd/even transpose edge).
