CPU / GPU comparisons at the new ends for Venetian Blinds (width 1, width
and feather 32000), Radial Wipe (feather 32000), Grid (border 2000),
Scatter (1000), Beam (4000), Change Color (1710 degrees) and Turbulent
Displace (seed 100000). The comparison counts infinity on both sides as
equal, so Levels (Individual Controls) gets a direct check that the GPU's
output is finite at the ends of its ranges. The Noise HLS test asserts the
spec's ranges, so it fails without them.
The 1e6 bound also capped curves that were finite before (gamma 0.1 on an
HDR value 4 x Input White is 4^10, about 1.05e6). The bound is now 1e30:
1e30 times the widest output range (2e4) is still finite, and every curve
below it renders as before. A test pins 4^10.
Random Seed takes 0..100000, After Effects' recorded valid range (and what
the other effects' Random Seed already takes). The CPU and GPU hash it the
same way with wrapping u32 arithmetic, so any seed costs the same.
Default and slider are unchanged.
Scale Height and Scale Width take -30000..30000 %, After Effects' recorded
valid range in the same units. The CPU and GPU share the matrix
(transform_matrix_px) and the buffer growth, which is capped at 16 Mpx
(transform_grow; the CPU test already renders 100000 %), so larger scales
stay bounded.
Default and slider are unchanged.
Starting and Ending Thickness take 0..4000, After Effects' recorded valid
range in the same units (pixels). The CPU and GPU renderers draw the beam
per pixel from its distance to the segment, within the layer's buffer, so
a thicker beam costs the same.
Default and slider are unchanged.
Scatter Amount takes 0..1000, After Effects' recorded valid range in the
same units (pixels); the slider stays 0..127. The CPU and GPU renderers move
each pixel by one random offset of up to the amount, so a larger amount
costs the same; samples outside the layer are transparent.
Default and slider are unchanged.
Feather takes 0..32000, After Effects' recorded valid range in the same
units. The CPU and GPU renderers evaluate the feather per pixel in closed
form (a Gaussian of the distance to the wedge, radial_wipe_alpha), so a
wide feather costs the same and stays finite.
Default and slider are unchanged.
Width takes 1..32000 and Feather 0..32000, After Effects' recorded valid
ranges in the same units (pixels). The work stays bounded: the renderers
floor the width at 1 buffer pixel, sum at most 40 Gaussian terms per
pixel, and above 8 widths the feather is the even veil
(venetian_cover; the GPU hands that case to the CPU, as before).
Default and slider are unchanged.
Border takes 0..2000, After Effects' recorded valid range in the same units
(pixels). The CPU and GPU renderers compute the border per pixel in closed
form, so a wider border costs the same; one wider than the cells covers
them.
Default and slider are unchanged.
Hue Transform takes -1800..1800 degrees, After Effects' recorded valid range
in the same units. The CPU and GPU renderers wrap the hue (rem_euclid /
fract_euclid), so five turns render like the hue they end on, at the same
cost.
Default and slider are unchanged.
Hue, Lightness and Saturation go up to 1000 % and Grain Size down to 0 (it
keeps its wider maximum, 100), After Effects' recorded valid ranges in the
same units. Noise HLS Auto shares the controls and widens with them.
Defaults and sliders are unchanged.
The renderers need no change: hue wraps, lightness and saturation clamp per
pixel after the noise is added, and Grain Size is floored at 0.1 px on the
CPU and the GPU, so the new values cost the same and stay finite.
The amounts were written as "percent" in keyframe text because their range
was 0..100, and Grain Size would become "percent" at 0..100; UNITS rows keep
the units they had.
Blend goes up to 10000 (it keeps its minimum of 1, below After Effects' 5)
and Jitter up to 500 %, After Effects' recorded valid ranges in the same
units. Defaults and sliders are unchanged.
The CPU and GPU renderers capped Jitter's dither at 100 %, so higher values
would be stored but render as 100. Both now take it from one function,
four_color_jitter, which keeps the dither linear up to 500 %. Blend 10000
is a finite softening (Blend squared) at the same cost.
Jitter was written as "percent" in keyframe text because its range was
0..100; a UNITS row keeps that unit.
Input/Output Black and White of every channel take -10000..10000 and Gamma
goes down to 0 (it keeps its wider maximum, 10), After Effects' recorded
valid ranges in the same units (the .aep mapping is Conv::Plain). Defaults
and the 0..1 / 0.1..3 sliders are unchanged.
Gamma 0 renders as the existing 0.01 floor, an exponent of 100, so an HDR
value a few times Input White would overflow f32 and an infinite curve
times an empty output range is NaN. The curve is now bounded at +-1e6 on
the CPU (Lv::apply) and the GPU (fxt_lv), so the output stays finite over
the whole range; values below the bound are unchanged.
The engine regression (tests/effect_ranges.rs) sets both ends of each row
through prop.set, checks undo/redo, save and reopen, and that a project
saved with the narrower ranges opens with the new ones and its values.
Past 1024 followed files, the trim kept only files with a cached LUT and
dropped the one being noted (its LUT is cached right after), so a later
edit to it went unnoticed. The tests start from an empty folder.
The watcher stamped only the files whose parsed LUT was still cached, so
with more LUTs than the cache keeps, an edit to an evicted one left the
viewer's frames stale. The cache now remembers the stamp each LUT file was
last read with (bounded separately), and keeps at most 64 LUTs and 512 MiB
of tables. Frames finishing while the viewer empties its cache are refused.
load_lut kept the first result for a path for the life of the process: an
edited file, or one created after a failed load, was never read again.
Each file-backed entry now keeps the file's size and modification time and
is read again once they move; inline .cube text stays cached by content.
The cache keeps at most 32 LUTs (least recently used goes first).
* Effects: cap Camera Lens Blur and median radii
Camera Lens Blur built its iris table (one row per pixel of radius) from an
uncapped Blur Radius before any size check, and the median window is filled
(2r + 1)^2 per row from an uncapped Radius, on the CPU and the GPU. The
radius is now capped where the work is built: 2000 buffer pixels for the
lens iris (UI max 500) and 512 for the median window (UI max 255), on both
paths.
* address review: cap camera lens reach with the spans
* Simulations: cap the steps a layer time can ask for and bound checkpoints as they are made
* address review: keep the requested sim state when trimming checkpoints
* address review: drop only the excess sim checkpoints when trimming
* Roto Brush, Object Matte: decode frozen mattes only at the layer's full-resolution grid
* address review: frozen matte size mismatch falls back to computed matte
* address review: frozen-size-mismatch test compares against a render with no cache
* Puppet: clamp an imported Expansion before padding the outline grid
* address review: non-finite expansion compares with zero expansion in test
* address review: trace over-budget puppet outlines at a coarser resolution; NaN expansion test
load_lut took any source containing "LUT_" for inline .cube text, so a
path like /luts/LUT_Rec709.cube was parsed as text, failed, and the
effect passed the image through. A .cube can only parse with a size
header and data rows on separate lines, so a newline (after trimming,
as the path already is) is what tells text from a path.
#2944 (497a056c) normalises each box-blur mean in f64 and rounds once
(it was rounded to f32 first, then scaled), and counts repeated edge pixels
with one multiply instead of adding them one by one. Its PR states results
change only by float rounding, and it added the focused regression test the
golden-test rule asks for (box_row matches a direct sum). The golden hashes
are only enforced on aarch64 macOS, so Linux PR CI passed, and every
completed macOS CI run on main since #2944 has failed (497a056c's own run
was cancelled by a newer push).
Bisected on an M5: the golden tests pass at ed085bd4 and fail at 497a056c
with the same 52 hashes macOS CI reports. All 52 are 32 bpc frames of
effects that blur through box_plane/gauss_plane (Lightning, Advanced
Lightning, Inner/Outer Key, Caustics, Paint Bucket, Vegas); every 8 bpc frame
is unchanged. All 52 frames differ by at most 4.8e-6 per channel, with no new
non-finite values.
Only the pinned hash values change; LIBM_VARIANTS is untouched.

* Box blur: count repeated edge pixels instead of visiting them, and bound the radius
* address review: box blur first mean ignores an unused edge term (inf * 0 gave NaN)
The pixel it read was inside the cylinder at 400 % too. Put the axis on the left
edge and read a pixel past the 400 % radius, with a 400 % run showing it is empty.
The Radius parameter was limited to 400 %, so a larger value was clamped and drew
a smaller cylinder than After Effects' CC Cylinder, whose range the report gives
as 0 to 30000 %. Raise the hard maximum; the slider's visible range is unchanged.
* WebAssembly ABI 2: neighbouring frames for effect plug-ins (#2773)
A wasm plug-in can export ec_api_version 2 and ec_render2 to receive the layer's previous and next frames, their layer times and validity flags. Neighbours come from PluginHost::input_at, are resampled onto the current grid, and are zeroed when absent. ABI 1 modules (ec_render) load and render unchanged; the manifest api stays independent. A layer with an ABI 2 plug-in keys the render cache on layer time; the Plug-in Library accepts ABI 1-2 releases. Docs, help text and tests updated.
* Fix ABI 2 neighbour times on NTSC frame boundaries
ime * fps is often a few ulps off an integer at rates such as 24000/1001. The old boundary test then took the bracket branch and passed the current frame back as prev (or
ext). Treat a near-integer as a frame boundary within 1e-6 frames, and test 2400 frames at 24000/1001: every boundary must get the frames either side. Also document the loader helpers for the docstring coverage check.

Related to #1365. Display labels only; effect, command, parameter, panel and serialized ids and the AEP/script match-name tables are unchanged.
- 69 Cycore CC effects, Key Light, Mocha shape, Lumetri Color/Scopes and the Mercury renderer labels get descriptive names; the old names stay case-insensitive lookup and search aliases.
- Backend::parse accepts the new renderer labels, so reported settings round-trip.
- Display names are unique per language in every effect catalog (new test).
- Warp Stabilizer and Roto Brush keep their names until RFC-0029 settles.
- Mapping in docs/feature-naming.md.
After Effects' Channel Info kind 2 "(copy)" was imported as R, G, B or A.
EffectCraft's EXtractoR resolves those names through the footage's aux planes
first, and an OpenEXR keeps its own R/G/B/A planes, so "(copy)" read the
original file plane and dropped what an earlier effect did to the channel.
"(copy)" is now a reserved EXtractoR channel name (EXTRACTOR_COPY) that the
CPU and GPU renderers never look up in the aux planes: it is the input's own
channel of the same position. The importer writes it for kind 2.
Render regression: a modified input buffer with same-named R/G/B/A aux planes
of other values; GPU parity case with (copy) on an aux scene with R/G/B.
* Echo: swap Composite In Back and Composite In Front (#3124)
After Effects 2026 renders of the importer sample (opaque test card with a
moving square, one echo at -1/30 s) show Composite In Front keeping the
layer on top (the output equals the current frame) and Composite In Back
putting the echo over the layer. EffectCraft had the two the other way
round, which made ~0.5 % of the pixels differ at the moving edge. The CPU
and GPU (fxn_echo) arms are swapped together.
A regression test rebuilds row 130 of the test card and checks Add,
Maximum, Minimum, Screen and both Composite operators against the measured
After Effects row. Blend is left unchanged: the sample (one echo, intensity
1, decay 1) cannot tell its normalisation apart.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Echo: Blend sums the weighted frames like Add (#3124)
New After Effects 2026 renders (our own 1110-extra sample, 16-bit PNGs,
opaque test card with a moving square) show that Blend does not normalise:
- 3 echoes at intensity 1 and decay 1 give four times the layer.
- 2 echoes at intensity 0.5 and decay 0.5 give alpha 0.875
(0.5 + 0.25 + 0.125).
EffectCraft divided by the number of frames. The division is gone on the
CPU and in fxn_echo_fin on the GPU.
The same sample pins Composite In Back with three echoes: each older echo
goes over what is there with its weight as opacity, so the oldest is on
top, as the branch already does. Composite In Front with three echoes
equals the current frame.
A regression test checks four measured 16-bit rows within 4 codes (24 on
square-edge pixels): Blend 3/1/1, Blend 2/0.5/0.5 with alpha, and both
composite modes at 3 echoes, -0.08 s, decay 0.5.

* 3D: Orientation and X/Y/Z Rotation turn Z first, keyed Orientation slerps, as After Effects
After Effects composes a 3D layer's (and a camera's) Orientation and its X/Y/Z
Rotation as Rx * Ry * Rz each, Orientation before the axis rotations; EffectCraft
used Rz * Ry * Rx. Measured on synthetic AE 2026 cases: Orientation [10,20,30]
(488) was 5.2 % of the frame off and now matches to the anti-aliased edge (0.03 %);
X/Y/Z Rotation 10/20/30 (800), Orientation + X Rotation (801) and one-node
cameras (804, 805) likewise.
Keyed Orientation moves along the shortest arc between the keys (quaternion
slerp, eased in time, angles written in [0, 360)): keys [0,0,0] -> [10,20,30]
read back [6.2643, 9.3531, 15.2190] half-way where EffectCraft gave [5,10,15];
[0,0,0] -> [60,80,40] linear and eased match AE's read-backs within 0.002 deg.
lookAt() returns AE's angles (z axis on the target, x axis level; two AE
read-backs within 1e-3 deg). The camera tracker, VR editor, Look At and orbit
commands use the new decomposition.

* Keyframes: a linear side next to an eased side has 16.67 % influence, as After Effects
In a segment that is Bezier on one side and linear on the other, the linear
side keeps the segment's average speed, but with the 16.67 % influence After
Effects shows for linear keys in the Keyframe Velocity dialog (and reports to
scripts), not 33.3 %. Measured on an After Effects 2026 time-remap render (a
square at x = 50 + 455 * remap): out of a key at 2 s (3.5, speed 0, influence
50 %) into a linear key at 4 s (0.5), AE plays 3.290 at 2.5 s and 2.657 at
3 s; EffectCraft played 3.308 and 2.629 (8 and 13 px off), now the same
square positions to the pixel.
LINEAR_SIDE_INFLUENCE is used by evaluation (scalar, per-dimension, paths and
spatial), side_ease (Graph Editor, velocity dialog, keyIn/OutTemporalEase) and
the Lottie export, so exported easing plays as EffectCraft does. Segments
linear on both sides stay straight lines.

* Timewarp: retime the layer's source without the effects above it, as After Effects
After Effects' Timewarp reads the layer's source (with its masks) at the
retimed times and ignores the effects applied before it: a red solid with a
Gradient Ramp and then Timewarp (Speed 25) renders as the red solid in AE
2026 (EXPORTER e2 read-back). EffectCraft retimed the layer with its
effects (mean difference 127.5/255 over the comp), now identical (0, CPU and
GPU). Echo, Posterize Time and the other time effects keep reading the
effects before them, as measured before.

* Image sequences: a gap in the numbering holds the previous frame, as After Effects
After Effects 2026 shows the last existing file across a gap in a sequence's
numbering (case 860: files 1, 2, 4, 5 show frame 2 at frame 3; VERIFY
read-back). EffectCraft drew colour bars there. The media pool now holds the
previous file (Footage::sequence_file_held); colour bars remain only where no
file precedes the frame. Missing-frame reports on import are unchanged.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Review: keyed Orientation uses LINEAR_SIDE_INFLUENCE for linear sides; real NaN assert
evaluate_orientation still gave a linear side (and the unreachable missing-key fallback)
1/3 influence while segment_value, side_ease and the Lottie export use
LINEAR_SIDE_INFLUENCE (1/6), so a keyed Orientation next to an eased key moved on a
different curve than every other property (CodeRabbit on #1876). New test:
orientation_linear_side_next_to_an_eased_side_matches_a_scalar (both directions).
The always-true NaN assert in keyed_orientation_slerps_as_after_effects now checks that
a non-finite key comes back as given; Property::value_at says why the match_id
"orientation" routing is safe.

Conflicts with the Cryptomatte import (#3109), the quick wins (#3119) and

* AEP import: map the Cryptomatte plug-in to EffectCraft's Cryptomatte
The importer reported every instance of the free Cryptomatte plug-in
(match name `Cryptomatte`) as a lost effect. It now becomes
`ec.3d.cryptomatte`:
- CryptomatteData decodes the plug-in's Settings data (its own
little-endian layout, documented in docs/aep-format.md 3.7): the
Cryptomatte layer name and the selection text, both carried verbatim.
- Output maps to Display / Matte Only (Colors -> Colors, Matted RGBA ->
Matte, Matte Only -> Matte Only). Matted Colors, Selection Mode when on,
keys or expressions and anything else stored are reported, and
unreadable data is reported as damaged.
- EffectCraft's Cryptomatte gains a Layer Name text parameter. A layer the
footage has under exactly that name wins; otherwise the Layer popup
decides as before. The CPU, GPU and pick paths share one resolver
(AuxChannels::resolve_crypto_layer_named). Without it, plug-in layer
names such as Crypto_Material would silently fall back to the first
layer.
On a real production project this takes the effect losses from 132 to 44.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* AEP import: check Cryptomatte against an After Effects 2026 sample of our own
A sample made in After Effects 2026 (plug-in 2.6.6: a fresh effect,
Selection Mode on, each Output item, with read-backs and renders)
corrected three points of the mapping:
- Selection Mode on was dropped silently: After Effects writes it as a
default-state record (tdsb 3) holding 1, which the general reader does
not take. The Cryptomatte step reads that record itself and reports it.
- No Output record is now the plug-in's default Colors, also for an
instance that borrows the project's definition (every instance after
the first), which was reported as having no reliable default and fell
back to EffectCraft's Preview. Keyed or unreadable Output values fall
back to Colors too, still reported.
- Matted Colors imports as Display Matte (the same matte over the layer's
own colours) instead of Preview, still reported as an approximation.
docs/aep-format.md 3.7 gets the sampled Output default, the tdsb 3
Selection Mode record and the real fresh Settings data (an empty text of
length 1 and its MurmurHash3, twice, not cry1 and zeros); docs/aep-import.md
the render comparison with After Effects (Matted RGBA matches; Matte Only
differs in alpha; Colors with no layer chosen shows another layer).
Tests: the exact fresh Settings bytes, tdsb 3 Selection Mode, borrowed
definitions, and an opt-in test against the sample once it is in the
corpus (aep/cryptomatte.aep, ignored until the corpus pin includes it).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* AEP import: write Cryptomatte's popup items in the test as After Effects does
The injected Cryptomatte definition wrote `pdnm` and `fnam` as `LIST`
chunks. After Effects writes them as plain chunks whose body is chunks
(`NESTED_IDS`), and the reader only looks there, so the tests never read
Output's item names: they passed through the fallback for a definition
with four items and no `pdnm`, which uses the plug-in's own list.
The harness now writes both as After Effects does. New tests check that
the injected definition reads back with its items and instance name,
that Output is mapped by the item the stored index names (items in
another order, case, an unknown item), and that the fallback without a
`pdnm` still works. With the old `LIST` form, or with the mapping
ignoring the items, the new tests fail.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* AEP import: check Cryptomatte's layer and selection against presets of our own
The After Effects 2026 sample 1400 now has two preset compositions that choose a layer and
pick one object (box_red on CryptoObject) or one material (mat_paint on CryptoMaterial).
CryptomatteData reads both as they are; the picked tokens are the EXR manifest's hashes,
which EffectCraft's selection grammar reads the same as the names.
- The u32 at 108 is MurmurHash3 of the selection text with its NUL (three texts).
- A unit test pins the 127-byte preset data; the sample test now covers all eight
compositions with their layer and selection.
- Render check: EffectCraft's matte covers exactly the pixels After Effects draws as
selected, edge coverage within 0.0002. docs/aep-format.md 3.7 and docs/aep-import.md.

* Cryptomatte import: report damaged Settings and Selection Mode records
Review follow-ups for #3109:
- CryptomatteData refuses a selection text without its NUL and checks the zero byte
at 112 for an empty text too.
- A Settings record without its data, and a Selection Mode record whose value cannot
be read, are reported as damaged data, not taken as the default.
- Layer Name is the effect's last parameter, so the earlier parameters keep their
indexes and upgraded instances have the same order as new ones.
- A Cryptomatte layer name is matched as given before it is trimmed.

* Cryptomatte: the Layer popup lists the footage's Cryptomatte layers (#473)
The popup was the constant CryptoObject / CryptoMaterial / CryptoAsset. It now lists the
Cryptomatte layers of the layer's OpenEXR footage, and those three when there are none. The
stored value keeps its meaning (0-2 the standard layers, 3 and up the file's other layers in
name order), so older projects render the same.

* Color Stabilizer: sample the reference where the points were at the reference time (#3125)
After Effects 2026 samples the reference frame at the positions the
Black / Mid / White Points had at the reference time. With keyframed
points it therefore corrects even a static picture: our importer sample
(colstab-43-keys, Levels, Black Point (64, 90) -> (151, 99) over 1 s)
renders at 0.5 s as the Levels map out = a + b*v of the ramp with
b 1.2935..1.2965 and a -0.2365..-0.2350, which is the Black Point's
current sample (107.5, 94.5) sent to the reference sample at (64, 90).
EffectCraft sampled both frames at the current points, so the card
stayed unchanged (slope 1). The samples now read the points at the
reference time through the host (params_at), falling back to the
current points without one. CPU and GPU share the sampler
(color_stabilizer_maps).
Sample Size's unit is not pinned by the samples (every size 1..40 leaves
the card unchanged in After Effects; that only bounds the sampled area)
and is left as it is.

* Linear Wipe: After Effects' edge position and feather profile (#3125)
Measured on our importer samples (linwipe-*, 2026-11-05, After Effects
2026, 320 x 180):
- The edge sits at lo + completion * (hi - lo) whatever the feather (the
set-all render's 50 % line is at -5.25, predicted -5.266); 0 % keeps
the layer and 100 % clears it even with Feather 32000. EffectCraft
extended the travel by the feather, 13 px off at Feather 16.
- The feathered edge is the hard matte blurred with the layer's edges
repeated: three box passes of radius 6 per axis fit Feather 16
(sigma 6.35..6.6, taken as Feather / 2.5), including the extra
opacity where the edge meets the layer's left side. EffectCraft drew
a linear ramp Feather px wide.
- Without feather the edge pixel is anti-aliased (143/255; coverage
gives 0.6). EffectCraft drew a hard step.
set-all alpha: before max 195, 4646 px (8.1 %) off by more than 2/255;
after max 15, 529 px (0.9 %), all along the layer's left side (at most
2 elsewhere). Feather 0 renders: max 112 -> 10 on the edge column.
CPU: coverage matte, raster::gaussian_blur (3 box passes, edges
repeated); GPU: the same matte from gen_linear_wipe (new modes), its
gaussian_blur, then a multiply, so both match. Sigma is capped at twice
the layer's longer side; NaN values leave the layer as it is.
Projects saved before keep the old ramp: a hidden legacyFeather
parameter that migrate::legacy_default sets on upgrade (as for Ripple
and Block Dissolve).

* Linear Wipe on the GPU: 100 % clears the layer before the angle is read
A NaN angle left the layer unchanged on the GPU while the CPU cleared it.

After Effects 2026 accepts 0 to 200 for Brush Size of both effects (a
script setting 201 is refused with "out of range 0 to 200"); the range
here ended at 50. The slider keeps its 0 to 50 travel; larger values are
typed.

Take recorded_value from #3134 for ordinary effects in import_mapped; the ValueRecord switch is gone (stored_value now reads default-state records too).

* Grow the buffer to the pinned quad so Corner Pin draws outside the layer rectangle (#1938)
* Corner Pin: grow through pad_sides, skip adjustment layers, clamp to the pixel budget (#1938)
grow_sides returns the four sides for Buf::pad_sides on both paths, replacing grow_to/regrow and the inline GPU copy. Growth is skipped on adjustment layers, cut proportionally to the shared pixel budget (and 16384 per side) instead of giving up, and covered by tests for a far pin, an adjustment layer and a degenerate quad.
* Corner Pin: give the grow_sides test its own doc comment (#1938)
* effects: Corner Pin keeps a finite buffer for non-finite pins and grows without popping as a pin moves far away
* effects: rustfmt the Corner Pin non-finite pin test

The reference test now checks the bound the PR states in the code space of the renders
(the sRGB curve x 6553.5) instead of a linear 2e-3, which allowed about 28 codes at the dark end.
