Subject: [PATCH 01/54] Render: drop the blanket layer cover from effect
 stacks; effects pay only what they need (#1205)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since #659 every text or shape layer with an enabled video effect grew its
effect buffer to the comp-sized layer rectangle before the stack ran, so
glow and blur — which only need their own margins — allocated a 1920x1080
RGBA32F texture per layer per frame in flight (~5 GB peak VRAM in parallel
export, measured on an RTX 3090).

Effects that actually place pixels outside the painted content already
grow the buffer themselves by exactly what they need (CC Tiler, CC Smear,
CC Mosaic sharp via layer_cover_pad / Buf::pad), on CPU and GPU. The
blanket target.cover(layer_size) in Renderer::run_effects_on, the
FxTarget::cover trait method with its CPU default, and the GPU
GpuTarget::cover texture allocation are removed; Buf::cover/cover_plan
stay as the effects-crate helpers they were designed as.

The #659 regression tests (tiling across the layer region, centred-shape
edge pinning) and the render/effects/gpu suites pass unchanged.

Subject: [PATCH 03/54] Render: ask the effect spec whether a stack can skip
 the layer cover

Matej's follow-up kept the known-margin set as SKIPS_COVER and the renderer looked the ids up. Ask EffectSpec::skips_cover instead so a new margin effect opts in on the spec rather than in run_effect_stack. Tests pin align_plan to cover_shift mod 64 and that Twirl still takes the full cover.

Subject: [PATCH 04/54] UI: rescan system fonts from the font menu; Linux scan
 smoke test (#1089)

Fonts installed after EffectCraft launched (dnf, GNOME Font Viewer, a
drop into ~/.local/share/fonts) stayed invisible until restart: only the
startup background scan ran, and the report in #1089 could not tell
discovery gaps apart from a stale scan.

- The font menu's filter row gains a Rescan Fonts button (Character and
  Properties panels share the popup) that runs the existing
  text.fonts {rescan} command and reports the number added in the status
  line. The press doesn't flip the Variable-fonts filter (the button is
  above the row's click area and closes the popup on top of it).
- system_scan_finds_fonts now asserts, on a native fontconfig desktop
  (any machine with /etc/fonts, which includes the Fedora reporter's and
  the CI runner), that the scan lists installed families rather than
  silently returning only the bundled fonts: 870 faces in ~10 ms on an
  Arch box.

Tests: ui_font_search 4 passed (new rescan test drives the real popup);
effectcraft-text lib system scan green; fmt and clippy --all-targets -D
warnings clean. Translations for 'Rescan Fonts' in all six catalogs.

Subject: [PATCH 05/54] Keep the font rescan off the filter label and off the
 UI thread.

The 180 px font menu pinned Rescan Fonts over "Variable fonts only", and the click walked every fontconfig directory on the frame thread. The button is now its own row, and the scan runs on a background thread that the frame polls. The Linux face-count assert is left to the native-fonts gate.

Subject: [PATCH 07/54] =?UTF-8?q?i18n(ja):=20panels=20and=20dialogs=20(300?=
 =?UTF-8?q?=20rows;=2027%=20=E2=86=92=2039%)?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The panel catalog behind the menu bar translated the dialogs and
Preferences, but much of the work area was still English: panel tabs, form
fields, panel context menus, the tracker and graph controls, text-panel
options, the File panel's footers and the credits. Add 300 rows to the
Japanese catalog — and the matching Simplified and Traditional Chinese
sources the tests keep it in step with (the other languages may lag, an
untranslated row falls back to English):

- panel tabs (dock.rs / dock_ui.rs titles), the Project panel's columns,
  footer tooltips and column menu;
- form and dialog labels and choice options (the forms the panels open —
  import, interpret footage, render queue, trackers, text animators…);
- panel context menus (timeline layer/property menus, graph editor);
- the tracker, graph editor, text-panel, animator and Content-Aware Fill
  labels;
- the Preview panel's transport tooltips, credits table headers and sort
  options, the composition-settings tabs and the About links;
- the engine's text-animator menu labels, added as a data source like the
  settings pages (they are interface text the panels draw).

Strings are wrapped where they are drawn with the existing `tr`/`tr_args`
mechanism (the label helpers already ask the catalog, so the data tables
need no new ids); the catalog tests keep the three complete languages
listing the same sources, reject duplicate or empty rows and keep the
placeholder counts. A new test assertion in
`japanese_rows_translate_the_panels` pins a sample of this step.

The panel catalogs are now 993 Japanese and 995 Chinese rows (the two
Chinese catalogs are the complete source list); with the 628-row menu
catalogs Japanese is 1,621 of ≈ 4,200 interface strings (39%, up from 27%).

Still English: effect parameter names (≈ 1,650 registry names, drawn from
the model, not the catalogs), Home-screen literals, tooltips drawn from
engine data, engine error messages, and the rows other languages lack.

Docs: localization-parity (header, per-language table, overall share,
revision history), ROADMAP (language table, progress log, revision history).

Subject: [PATCH 08/54] i18n(ja): add the missing panel rows and recount
 localization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review follow-up to the panel/dialog step: the composition-settings tabs
translate "Basic" and "Advanced" through `tr(variable)` and the Preview
transport translates "Play/Stop", but none of the three had a catalog
row, so they stayed English. Add them to the Japanese, Simplified and
Traditional Chinese catalogs and pin them in
`japanese_rows_translate_the_panels`.

The shared "Type" key means "kind" in the Project column and the Camera
Settings dialog, so the Chinese rows read 类型/類型 instead of 文字
("text").

Keep the graph button bar's automation labels English: translate only
the drawn label and tooltip, and translate the stored English strings
when the hidden-button menu draws them.

Recount the docs from the catalogs: 628 menu rows, 996 Japanese and 998
Chinese panel rows; count Simplified Chinese's 306 effect names in its
numerator (46%) and average the ten After Effects languages the table
actually names (21%, not the stale 27%). Update the measurement basis,
the cross-references in gaps.md and target-app-parity.md, and ROADMAP.

 1,626

1,626 is the Traditional Chinese total translated-string count; the panel
catalogs carry 998 source rows each (996 in Japanese), as
docs/localization-parity.md measures.

Subject: [PATCH 10/54] Scripts: the Startup and Shutdown folders run at launch
 and quit

Scripts in Scripts/Startup and Scripts/Shutdown in the settings folder
were never run. The desktop and web apps now run the Startup scripts at
launch, before a project opens, and the desktop app runs the Shutdown
scripts as it quits, after the project is closed. Each folder runs in
alphabetical order with case ignored, and files larger than 16 MiB are
not run. A Startup script that fails is reported in a toast and in the
log, a Shutdown script that fails is reported in the log, and the next
one still runs.

A Startup script that waits in a modal dialog goes on when the dialog
closes, while the next scripts run. A Shutdown script's dialogs close
as if canceled. With the settings folder on disk, each script runs as
its file, so #include, $.fileName and $.evalFile resolve against the
script's own folder.

The new commands file.runStartupScripts and file.runShutdownScripts
return the scripts that ran, those still waiting in a dialog, and those
that failed. Like script.run, both are refused in confined automation
sessions, in batches and in script steps, which now read one list of
script commands (RUNS_SCRIPTS). The list also holds window.scriptPanel
and window.restoreScriptPanels, which run ScriptUI panel scripts and
were not refused on main either. The apps still call
window.restoreScriptPanels at launch. plugins.md, scripting-parity.md,
gaps.md, target-app-parity.md and agents.md describe the folders. Each script
still runs in its own global scope, so a Startup script's variables are
not available to later scripts.

Subject: [PATCH 11/54] Interpret Footage: Cineon Settings convert DPX and
 Cineon log scans

DPX and Cineon footage showed its log code values as stored, with no
way to convert them. Interpret Footage now has the Cineon Settings that
After Effects' help page describes: Logarithmic Conversion, the
Converted Black and White Points, the 10 Bit Black and White Points,
Current Gamma, Highlight Rolloff and Units. With Logarithmic
Conversion on, the code values of each decoded frame are converted
from printing density to the Current Gamma between the converted
points, before Separate Fields, Frame Blending, Interpret As Linear
Light and the working space use them. With it off (the default), the
values stay as stored.

file.interpretFootage and file.interpretProxy take the settings as
parameters and report them. They return an error for out-of-range
values, and for Cineon parameters when none of the items is a DPX or
Cineon file. Apply Interpretation copies the settings between DPX and
Cineon files.

Subject: [PATCH 12/54] Interpret Footage: the Footage panel, thumbnails and
 tracking show Cineon Settings

The Footage panel, the Project panel thumbnail and the native-size source
frames that tracking, mask tracking, scene detection and auto-trace read took
DPX and Cineon frames straight from the file, so they showed the log code
values while a composition showed the converted ones. Each now applies the
footage's Cineon Settings, as the composition renderer does.

Subject: [PATCH 13/54] Docs: Cineon Settings white point converts exactly only
 without Highlight Rolloff

The footage page said the 10 Bit White Point becomes the Converted White
Point. That holds with Highlight Rolloff at 0; at the default 20 the top of
the converted range is bent into a curve, as in the Cineon Converter effect,
and the white point converts to a lower level.

Subject: [PATCH 14/54] CC Bubbles: bubbles at the layer's edges refract its
 edge pixels, not a pale fill (#2024)

Near the borders a bubble's refraction (liquid) or reflection (metal) sample
lands outside the layer. sample_bilinear returns transparent there, so the
pale stand-in colour for transparent pixels showed through, a band of washed-out
bubbles along every edge. Sample with edge pixels repeated instead, on the CPU
and in the GPU kernel; the pale colour stays for genuinely transparent pixels.

The CC Bubbles golden hashes are re-pinned (the half-resolution cases pad the
buffer with transparent pixels and are unchanged).

Subject: [PATCH 15/54] Shapes: add the Wiggle Transform path operation, which
 wiggles paths and each Repeater copy

A shape layer's Contents > Add menu had every After Effects path operation
except Wiggle Transform. It is now a shape item (layer.addShapeItem kind
wiggler, "ADBE Vector Filter - Wiggler" for scripts) with Wiggles/Second,
Correlation, Temporal Phase, Spatial Phase, Random Seed and a Transform
group whose Anchor Point, Position, Scale and Rotation set how far each
transformation wiggles.

The values come from the Wiggly selector's noise, with each Repeater copy
as one unit: the copies of a Repeater above the operation, in its group or
a nested one, wiggle independently as far as Correlation allows, and the
copies of a Repeater below it wiggle the same way. A paint above it whose
paths all move by one matrix moves its gradient and stroke scale with them.
The layer cache keys a layer with a Wiggle Transform by time.

 ## Progress log
 
+- 2026-10-24: Shape layers have the Wiggle Transform path operation (Contents ▸ Add, or
+  `layer.addShapeItem {kind: "wiggler"}`): it wiggles the anchor point, position, scale and
+  rotation of the paths above it by random amounts that change over time, up to the Transform
+  values it holds. The copies of a Repeater above it wiggle independently as far as its
+  Correlation allows; with the Repeater below it, they wiggle together.
 - 2026-10-16: Convert To Bezier Path turns a shape layer's Rectangle, Ellipse or Polystar
   path into an editable Path 1 with the same geometry, as After Effects does; it used to
   apply to mask RotoBezier only, so a parametric shape path could not be converted at all

Subject: [PATCH 16/54] =?UTF-8?q?Scripts:=20File=20=E2=96=B8=20Scripts=20e?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Edit ▸ Keyboard Shortcuts now lists the scripts File ▸ Scripts lists, under
File ▸ Scripts, and a key given to one runs it as its menu entry does. The
key is bound to the script's file name (file.runScript {"name": ...}) and is
saved with the preset. File ▸ Scripts and the macOS menu show it.

The shortcut table lists the Scripts folder again when a script is installed
or uninstalled, when the editor opens and when shortcuts.list runs.
shortcuts.set and shortcuts.reset look a script up in File ▸ Scripts' list
as it is now, and a script it doesn't list is an error instead of a key for
Run Script File....

Subject: [PATCH 17/54] Scripts: a key changed to another key updates the
 native menu

The native menu's state key hashed only the number of shortcut
bindings, so changing a binding from one key to another left the
number the same and could keep the old accelerator on the item. The
key now hashes each binding and its keys.

Subject: [PATCH 19/54] Expressions: a layer is a callable property group

In After Effects a layer is a property group: thisLayer("transform"),
thisComp.layer("Other")("effects")("Blur"), thisLayer(1). In
EffectCraft's expression runtime a Layer was a plain object, so those
failed with "TypeError: not a callable function", including the
references the pick whip writes with Compact English off
(thisComp.layer("Other")("effects")("ec.noise.fractal")(...)).

A Layer is now callable like a property group (built as __mkGroup
builds groups), looking up its own properties by match name, name or
index, and keeps its methods, name and index. The places that took a
layer for a plain object (the result reading as the layer's index,
thisComp.layer(layer, offset), a Layer Control's value handed through
the property proxy) accept it.

Test: layers_are_callable_property_groups (fails before).

Subject: [PATCH 20/54] Expressions: a layer is made once per evaluation, and
 only functions are checked for being one

A Layer is now a callable function with its own prototype, which costs
more to make than the plain object it was. __layer(c, l) makes each
layer once per evaluation (kept in __S, which __begin resets), so an
expression naming the same layer many times builds it once. That covers
thisComp.layer(...) in a loop, .parent, a Layer Control's value and
thisLayer.

The checks for a layer (the result, thisComp.layer(layer, offset), the
property proxy) read __isLayer only on functions. Numbers and other
primitives are no longer boxed to look the property up.

Timing (release, Windows, medians of 2000 evaluations, PR vs main):
- one evaluation building one layer: about 22 vs 16 us;
- thisLayer.transform.opacity: about 200 vs 170 us;
- 20000 thisComp.layer(1) lookups in one evaluation: 95 vs 138 ms.

Subject: [PATCH 38/54] Cineon: Interpret Footage and the Cineon Converter
 share one log-to-linear function

effectcraft_project::cineon_log_to_lin does the log-to-linear conversion
for Interpret Footage > Cineon Settings and the Cineon Converter's Log to
Linear. Both raise the result to 1 / Gamma, so Gamma 1 gives linear light
and the same Gamma gives the same values in both. The converter's Linear
to Log, its Log to Log reference and the GPU shader use the same Gamma
scale, with a smallest Gamma of 0.01 / 1.7 (CINEON_MIN_GAMMA).

A test runs the converter at Gamma 1.7 (the default), 1 and 2.4 and
checks it against Cineon Settings at each code value.

Subject: [PATCH 39/54] i18n: the panel tabs, and the labels the call-shape
 scan cannot see
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two English surfaces the translation work so far could not reach.

The dock's tab titles: `PanelKind::title()` is drawn by `dock_ui.rs`'s `tab_titles`, which listed only
the tabs that name a comp, a layer or a script and let every other one fall back to `title()`'s English
- so every panel tab (`Timeline`, `Preview`, `Properties`, `Effects & Presets`, ...) stayed English. The
Window menu already carries a (`window.panel`, title) row in every catalog, so the dock reads that pair
and falls back to the panel catalog for `Markers` (the one panel only it names); `History` and
`ScriptUI Panel` have no row anywhere and keep their English names. `app.auto`'s labels and the dock's
serialized state keep the English title, which the control channel needs.

The scan's blind shapes: `converted_panels_have_no_unwrapped_literals` only sees a literal that follows
a call token, so a label passed to a helper, the third argument of `Painter::text`, a `(key, label, ...)`
table, a `let` binding and a `match` arm were all invisible. The two that can be checked without
guessing are added (`helper_and_painter_labels_are_translated`), with the same single-character
exemption the call scan makes, and the 25 sites they find now ask the catalog (`Apply`, `Analyze`,
`Cancel`, `Create Camera`, `Add Point`, `Remove Point`, `Clear`, `Render`, `Stop`, `Save Current as
Template...`, `New Composition From Footage`, the three search fields, `(no composition)`,
`per second`, `Waveform`, `steps`), with 15 rows added to the Simplified and Traditional catalogs in
the conventions those tables already use (Render 算圖, Apply 套用, Add Point 添加點).

The `uic!` labels and the Keyboard Shortcuts dialog are a different shape and are still to decide
(#1451).

Verified on Linux: cargo fmt --all --check, cargo test -p effectcraft-ui-egui (every suite passes),
cargo clippy -p effectcraft-ui-egui --all-targets -- -D warnings clean. Reverting the dock's catalog
lookup fails `the_dock_draws_every_panel_it_can_in_the_interface_language`; unwrapping a helper or a
painter label fails `helper_and_painter_labels_are_translated` ("panels/project.rs:434: the interface
text \"Search project\" that widgets::search_field draws is not in the catalog").

Also answers #1451's question about languages whose rows have no Simplified row to be a subset
of: six labels the Composition Settings dialog draws from a `(label, value)` table, a tab array and
a `match` arm (`Square Pixels`, `Basic`, `Advanced`, `3D Renderer`, `Black`, `Composition Settings`,
plus `White` from the same `color_name`) had no row anywhere, so every interface drew them in
English; they have Simplified and Traditional rows now, in the existing menu wording. The seventh,
`Lock Aspect Ratio`, is only an automation name - the drawn label is `Lock Aspect Ratio to {}`,
which already had rows, and `comp_settings.rs` built it with `format!` where `dialogs.rs` already
used `tr_args`, so that one is wired now too.

Review fixes (CodeRabbit): the scan now runs over the whole file with line comments blanked, so a
`.text(` call split across lines is still one argument list - which found five more labels the
per-line loop could not see (`No effects. Drag one from Effects & Presets.`, the colour-ring hint in
`fx_editors.rs`, the Learn blurb, the Script Console hint, the Templates blurb, plus
`Building waveform…` from the review), all wired with rows. And the New Composition title is back to
the English source: `modal_fit` keys the modal id and the drag offset on the title (its own comment
says the id stays on the untranslated source) and translates the heading itself, so `tr(..)` there
would have moved the dialog when the interface language changed.

And the argument list is bounded by the call's closing parenthesis: `args_of` used to flush a
trailing argument at end-of-string, so a last argument without a trailing comma carried the `)` and
the source after it, which made the check skip it as "not a literal". Reverting that one line is a
two-line test (a literal last argument in `header.rs` is caught now and was silent before).

The label scan also understands the two string forms a label can be written in: a plain string ends
at the first unescaped quote, a raw string (`r"…"`, `r#"…"#`) at a quote followed by as many `#` as
opened it, and `literal_text` decodes the argument before the exemptions run - so an escaped or raw
label is checked like any other instead of being skipped.

Two more scan fixes from review: `without_comments` tracks the escape state rather than the previous
character, so a string ending in a backslash (`"a\\"`) closes where it should; and the scanned range
ends at the test *module* - the first `#[cfg(test)]` followed by a `mod` - rather than at the first
`#[cfg(test)]`, because `dialogs.rs` keeps a test-only helper above its test module and production
code between them was not scanned.

And call tokens are looked for in a code-only mask: comments blanked, the contents of plain and raw
strings blanked too, with the quotes kept and every byte offset preserved (a blanked character
becomes as many spaces as its UTF-8 length, and a debug assertion pins the mask length). The argument
list is read from the original source at that offset, so a sample string that quotes a call cannot be
mistaken for one. Building the mask from chars instead of bytes shifted every offset after the first
non-ASCII character, which the debug assertion now catches.

The dock's display path has its own test now: `tab_titles` is called with `general.language` set to
Chinese and the labels a window shows are asserted (`Timeline` 时间轴 ...), plus `History` keeping its
English tab and the English interface keeping all of them. Reverting the dock to `PanelKind::title()`
fails it with "Timeline is not drawn in Chinese", which the catalog-only test could not see.

Subject: [PATCH 40/54] Cineon: the Cineon Converter keeps its Gamma scale

cineon_log_to_lin takes the exponent scale from its caller. Interpret
Footage > Cineon Settings passes 1 (Gamma 1 gives linear light) and the
Cineon Converter passes 1.7, as before, so the converter's output and
its default Gamma 1.7 are unchanged. The converter's Linear to Log, Log
to Log reference and GPU shader return to their earlier code.

A test checks the converter at its default Gamma and at 2.4, for all
three conversion types, against the earlier formula.

Subject: [PATCH 41/54] Fix #2573: New Composition From Footage creates a
 composition

The empty Composition viewer's button only ran File > Import, so the picked
file landed in the Project panel and no composition was made. file.import
now takes newComp: when the import lands (at once or when its background job
applies), what it made becomes one composition via New Comp from Selection.

the catalog tests, and the row-count report test is enough to reproduce them

Subject: [PATCH 48/54] Keyframes: mute keyframes without deleting them (#1894)

Add a muted flag to Keyframe. Muted keys stay in the Timeline and Graph Editor (dimmed, selectable and movable) but evaluation skips them, so the active neighbours interpolate as if they were not there; auto-Bezier and eases use the active neighbours. When every key is muted the property falls back to its static value.\n\nkeys.setMuted {muted} mutes or unmutes the selected keys in one undo step. The Timeline context menu offers Mute/Unmute Keyframes and the Animation menu has Mute Keyframes. Muted keys have no Bezier handles and motion-path points are dimmed.\n\nLottie export omits muted keys (with a warning) because Lottie has no mute state; scripting keeps seeing them in numKeys/key().\n\nTests: keyframe evaluation (linear, auto-Bezier spatial, all muted), serialization and value replacement, engine command + undo, Lottie export.

Subject: [PATCH 49/54] Keyframes: offer Unmute Keyframes in the Animation menu

The menu only carried Mute, so unmuting meant the timeline's context menu.
Add the second row bound to `keys.setMuted {"muted":false}`, its translation
in the ten catalogs, and a test that runs both rows through Session::execute
with undo and redo.

Subject: [PATCH 50/54] Import: an MP4 lasts as long as its video edit list
 shows (#2592)

The reader reports a track's media duration (mdhd). For H.264 with
B-frames that runs past the last shown frame by the encoder delay the
edit list trims, so a 75-frame 25 fps clip imported as 76 frames / 3.04 s.
The footage's duration now follows the video track's edit list when it
is shorter (never longer; a delayed start keeps the reader's duration),
as the frame rate is already corrected from the header.

 After Effects

Since #2107, Replace Footage keeps an item's kind by default, so
replace() on a sequence item brought the new file's whole numbered run.
In After Effects, replace() swaps in the one file and replaceWithSequence()
brings a run; replace() now asks for exactly that.

Subject: [PATCH 52/54] Render Queue: elapsed and remaining time tick between
 frames (#2593)

The job reports its times when a frame finishes, so with slow frames the
Current Render strip held the same Est. Remain long enough to look
stalled, then jumped. Between reports both times now count on from the
last one, as a clock does (remaining never below zero, a finished job
stands still), and the panel repaints twice a second while rendering.

 RUNS_SCRIPTS as classified

file.runScript and script.run moved from REFUSED to RUNS_SCRIPTS, which
check_command refuses too; the audit test now looks there as well.
