Four extensions each carried their own copy of the toast-or-console
fallback, transform upload failures used a blocking alert(), and a
failed video drop onto Load Video only logged to the console. They all
go through showToast now, so every message looks and behaves the same.
The quick Reset under Image Crop + Rotate + Pad promised rotation, crop
and padding but ran the editor's full reset, which also restored fill,
feather and Align. It now resets only the shape, the same keys a source
swap resets. The editor's Reset transform tooltip names Align, which it
does reset.
The frontend hides a DOM widget below a zoom threshold unless it opts
out. The video transform nodes mounted their panel through the one
addDOMWidget call without hideOnZoom: false, so zooming out left an
empty box. A guard test now checks every DOM widget in the pack.
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.
Video Crop + Rotate + Pad drew its preview stretched after a resize. The
canvas is CSS-stretched to whatever box the panel is given, but
prepareCanvas() sizes the backing store from the element at DRAW time, so
a box that changes shape without a redraw shows the last frame at the
wrong aspect ratio.
The panel's ResizeObserver was created inside a `kind === "image"` branch,
grouped with the interactive drag handlers because the comment there
reasons about hit-testing. Hit-testing is only half of what it does. The
image node redrew on resize and looked right; the video node - a passive
preview with no other reason to redraw - did not.
Latent until panels started taking the node's leftover height: before
that the box could not change shape without a width change, and a width
change forced a relayout that redrew anyway.
The observer now runs for both kinds; only the drag handlers stay
image-only. Two tests hold the line - one fails if any canvas-painting
panel ships without a resize observer, one fails if this observer is
gated on node kind again. Verified by reintroducing the bug: the second
test fails and names the offending condition.
Dragging a node taller only ever widened its stage. The frontend
arranges widgets in one pass:
if (w.computeSize) -> fixed height, kept OUT of the split
else if (w.computeLayoutSize) -> joins distributeSpace(freeSpace, ...)
else -> one standard widget row
It is an else-if, so a widget declaring both is pinned by computeSize
and its computeLayoutSize is never called. Every stage, player and
filmstrip here derived that fixed height from the node's WIDTH, so the
extra height became dead space underneath. Compare was fixed by hand;
the other six had the same defect.
Adds js/shared/panel_layout.mjs with one fillNodeHeight() that deletes
computeSize and declares a floor with no ceiling - distributeSpace reads
a missing maxSize as Infinity, so the panel takes whatever is left.
Applied to Compare, Save Video, Load Video, Frame Chooser, Load Image +
Pad, Image Crop+Rotate+Pad, and the shared transform panel that Video
Crop+Rotate+Pad mounts. Removing computeSize also removed where those
nodes got their opening height, so Save Video, Load Video and Load Image
+ Pad now state a default; a saved size still wins through onConfigure.
Measured in the browser: all seven grow 1:1 with the node and clamp at
their own floor.
The panel audit now enforces it - a DOM panel is either a stage that
calls fillNodeHeight and never assigns computeSize, or is listed as
fixed by design - so a new panel cannot quietly reintroduce this.
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.
Implements the mocked-up sidebar refinements: each section header now
carries a small marker matching its on-canvas handle (cyan square for
crop, green rotate knob, orange diamond for padding), teaching the
editor's color language without explanatory text, and a Preview section
at the bottom of the sidebar renders the actual output composite - fill
background, rotated source clipped to the crop, padded canvas, no
overlays - live while dragging any handle.
Browser-verified: all three markers render, sections appear in order
(Crop, Rotate, Padding & mask, View & reset, Preview), and the preview
canvas resizes and repaints when rotation and padding change, with fill
color in the padding corners and image content in the center.
Feathering had two defects: the mask used max(original, blur), and a
blurred step edge sits at ~50% on the boundary, so the mask jumped
255->127 in one pixel - the visible seam line - and the output image was
never blended at all, ending in a hard cut against the fill. The mask
ramp is now pinned to full strength exactly at the edge (double the blur
and clip, then max with the original for thin slivers), and the visible
output fades into the fill color across the same ramp, so outpaints
blend smoothly in both the image and the mask.
The rotation knob now anchors to the outermost top-right corner of
source-union-output, so it stays visually attached when padding grows
the canvas instead of floating where the source corner used to be.
Save & close is now filled with the AusBoss accent; Reset all is styled
as a destructive red button.
22 Python + 9 JS tests pass, including new asserts that the mask ramp
holds >=200 on the first kept column (was ~127) and that the image
visibly blends into the fill. Live-browser verified: knob tracks the
outermost corner under 140/90px padding, buttons computed styles match.
Each playback tick awaits a frame fetch, and a Pause press usually lands
during that await. The tick only checked for cancellation at its start,
so after the await it re-scheduled itself anyway - a zombie loop the
button could no longer control, since the toggle keyed off the constantly
replaced timer handle. Repro was play, pause, play: from then on pause
presses landed mid-await and were overwritten.
Playback state is now an explicit `playing` flag (the toggle's single
source of truth) plus a session counter; ticks re-check both after the
await and die if the session changed, covering both pause and rapid
pause-then-play. Verified in a live browser with a deterministic harness
that clicks Pause at the exact moment a frame fetch starts: both race
cycles stop cleanly, no frame advancement while paused across 3s of
sampling, and normal play/pause still works.
Real-world scrubbing was still sluggish on large files for three reasons
the small test clip hid: decodes ran synchronously inside async route
handlers (stalling ComfyUI's entire web server, websocket included),
every request re-opened and re-probed the container, and mid-GOP targets
re-decoded from the previous keyframe each time.
- Route handlers now run decode/encode in worker threads.
- A persistent per-file decoder session keeps the container and codec
state alive: forward steps decode only the frames in between, backward
or distant jumps do one keyframe seek without reopening. Sessions are
LRU-capped and an idle reaper closes them after 60s so the file lock
is released (Windows users can delete/overwrite a clip they just
scrubbed) — a bug the test suite caught via WinError 32.
- A keyframe storyboard (up to 96 tiles) builds in a background thread
when a video is selected. Dragging the timeline draws the nearest tile
synchronously — measured 2.4ms input-to-pixels in a live browser —
and the exact decoded frame replaces it when it lands.
- The rotation handle emoji is replaced with a vector arc-and-arrowhead
glyph, crisp at any zoom and identical on every platform.
21 Python + 9 JS tests pass, including new coverage for session
forward/backward parity against fresh decodes and storyboard payloads.
Scrubbing previously used a 70ms trailing debounce, so nothing rendered
while the slider was moving and stale responses could rewrite frame_index
mid-drag (rubber-banding). Replaced with a latest-wins pump: the first
input fetches immediately, exactly one request stays in flight, and each
response re-reads the widgets so the next fetch targets the newest
position. Scrub frames download at 640px with widget sync off; drag
release, key release, and playback stop land one full-size frame that
snaps the widgets to the decoded position. Playback and held arrow keys
share the light path. Server side, per-file metadata is cached by
(path, mtime, size) so a scrub request opens the container once, and the
JPEG optimize pass is dropped for ephemeral previews.
Browser-verified on live ComfyUI: 41 burst inputs -> 23 fetches rendering
continuously during the drag, final widget lands on the last position,
and the displayed pixels match the exact final frame. Random-access
frame latency measured at ~18ms median on the test clip.
The rotation control moves from a stalk above top-center (stacked on the
pad_top diamond) to a rotate-glyph knob off the source's top-right
corner, with the help text updated.
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).
