Carry property, Font and Media Replacement overrides into the collapsed nested EvalCtx so nested layers render beyond the precomp frame instead of falling back to a clipped, flattened image. Key the layer cache on instance overrides to keep distinct collapsed instances isolated.
Much of a layer buffer is often transparent (a stroked ring, a glow-padded
text layer, a precomp canvas), yet every destination pixel sampled it
bilinearly, and 8/16 bpc comps then re-quantised the layer's whole rotated
bounding box.
- Bilinear warps skip 16x16 source tiles whose pixels (and a one-pixel
apron) all have zero alpha: their samples are transparent and were never
drawn.
- The fast affine warp reports the rectangle it changed and, given the
comp's levels, quantises each pixel as it blends it, so draw_comp has
nothing left to re-quantise for that layer. quantize_px moves to
effectcraft-raster for this.
- quantize_rect skips runs of four all-zero (+0.0) pixels, which quantise
to themselves.
- to_rgba8 / to_rgba8_over convert row by row instead of per 4-byte item.
Every pixel stays bit-identical: tests compare the warp against the
reference path, fused quantising against quantising after blending, and
the zero-run skip against per-pixel quantising.
With the previous commit, demo comp to H.264 (`cargo xtask bench --scenario
demo --format h264 --frames 300`, 11 interleaved runs on a 16-thread Ryzen):
wall 9.26 s -> 6.97 s median (-24.8%), 8.55 s -> 6.55 s min (-23.3%); CPU
time -23%. Output byte-identical.

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.
On an adjustment layer Motion Tile kept the comp-sized buffer whatever the
Output Width / Height, and the adjustment draw dropped any stack result whose
size differed from the canvas. After Effects grows (or crops) the comp
rectangle there as on any layer, so a Transform after it brings the extra
tiles into view, as in the frames attached to #1727 and #1409.
- motion_tile_frame: one output frame for the CPU and GPU effect; on an
adjustment it grows about the comp rectangle on whole pixels, keeps the
buffer at 100 % and past 16 384 pixels a side.
- adjustment_crop: the CPU and GPU adjustment draws put a stack result whose
frame changed back onto the canvas instead of dropping it (Enc::crop on
the GPU).
Tests: the #1727 After Effects frames (910 x 340 % and 90 x 340 % then
Scale 12 %), tiles past the frame and cropping on CPU, GPU vs CPU for
adjustment and full-frame layers.

Review: styled() kept the buffers it rendered instead of the ones LayerCache::insert returned, so
without a blending-space conversion concurrent misses still returned separate body and pass
buffers (and the GPU uploaded each).

Preview workers that start together miss the layer cache together, and each kept its own copy
of every layer; on the GPU each copy was uploaded and packed into its own Classic 3D atlas, which
ran the device out of memory on a cold start. LayerCache::insert now keeps the first buffer of a
key and returns it, and the renderer goes on with the returned buffer, so the workers share one.
Renders don't wait for each other: on the shared frame pool a blocking wait could end up beneath
the work it waits for (tried, it stalled playback for the wait's timeout).

After Effects 2026 in a 32 bpc project, Levels (Individual Controls) with RGB
(0.1, 0.9, gamma 1.5, 0.05, 0.95), Red Gamma 0.8, Green Input White 0.8 and
Blue Output Black 0.2 on grey steps 0..255 (case 904 E07): every step matches
"each channel's controls, then the RGB controls" with nothing clipped
(values below Input Black end below Output Black, above Input White above
Output White). EffectCraft ran RGB first and clipped "Off for 32 bpc Color"
(it could not see the bit depth): up to 27/255 off on 95 % of the grid; now
0 grid points off, max 1/255, CPU and GPU.
EffectEnv gains float_depth (the renderer sets it for 32 bpc projects), so
"Off for 32 bpc Color" clips in 8 / 16 bpc projects as before. Unclipped
values below 0 take the gamma mirrored through 0. Plain Levels keeps its
order (its channel controls were not measured); its clipping follows the same
rule. EffectCraft's own projects default to 8 bpc and are unchanged.

Engine part of viewer picking: replace / add / remove the top-coverage ID at a
layer-space point in one undo step, at the time the Selection was read. The
aux channels come from the render's own path (Renderer::layer_aux, shared with
the effect host; footage at its source time, 3D precomps) through a renderer
set up like Session::render (expressions, render prefs, layer cache). An
optional scale snaps the point to the pixel a preview at that resolution
samples. New effects::crypto_select quotes names and falls back to <hex> for
unnamed, wildcard-looking or ambiguous names. effect.cryptomatteAt is the
read-only hover query.
Turning Solo on or off hides or shows every other layer at every frame, so it
now recaches the whole comp. The kept span is widened by the comp's shutter
(phase and angle), since a frame's motion blur samples cameras, lights and
transforms up to three frames away. Comp::any_solo is shared with the
renderer so both read Solo the same way.

Guide layers render only in their own comp's viewer: a nested renderer (precomp, collapsed
precomp in 2D, Classic 3D and Advanced 3D, comps read by effects, aux passes, the GPU walk's
resident precomps) now runs with guides off (Renderer::nested_opts), so a precomp's guide
layers no longer show in the parent comp's viewer or in a "Current Settings" render.
The Timeline layer and Composition viewer right-click menus (shared layer_menu) gain a
Guide Layer item (a plain toggle, no check mark) acting on the selection, and guide layers show a guide mark
before their name in the Timeline.

In After Effects solo is not time-dependent: while any AV layer is soloed,
non-soloed layers are excluded at every time. The renderer, nested/collapsed
3D paths, engine viewer helpers and viewer hit tests only counted solo layers
active at the current time, so outside the soloed layer's in-out range the
whole comp reappeared. Drop the time condition (audio already ignored it).
Update the #66 viewer regression test to the AE behaviour and add a render
test for it.

Expansion was a fill plus a stroke 2·|expansion| wide, blended per pixel. Once the
expansion passed the shape's curvature radius the stroke's inner edge inverted: a
20 px circle expanded by 60 left a ring with the layer showing through the middle,
+600 cut only the original dot, and negative values left islands. The outline is
now offset with Offset Paths' geometry (round joins) and filled.

- Renderer: no cover step for adjustment layers (#686); their buffer is the comp below.
Restores a single CPU step in split adjustment stacks.
- Effect Controls rename (#953): focus the name field the frame it exists. Focusing an id
not yet drawn left AccessKit with a focus outside its tree (a panic in the consumer).
The tests double-click at 60 fps, within egui's double-click time.
- i18n: Russian, French and German entries for Copy Frame to Clipboard and the extrusion
Front/Bevel/Side/Back Color submenus added by today's other PRs.
- Tests: "fr" is now a valid language; the marker dialog's comment is focused on open
(#922), so Enter-is-OK is tested with the focus elsewhere; the toolbar gradient tests
give the selected layer its paint kind, since the toolbar mirrors it (#732).

- Footage sources: the cancellable wrapper (#784) forwards frame_with (#752 float curves)
and problem (#887); problem's default lives on the trait.
- Media: a called-off decode (#784) is not a footage problem (#887).
- Effect Controls rename (#953): Escape cancels (egui drops focus on Escape the same
frame), the Rename item is translated; regression test.
- i18n (#873): drop the /out-i18n/ ignore rule and the note about an uncommitted script.
- Tests: text range selector caps (#926) re-borrow the layer; the RAM preview test (#793)
sets the comp's own Resolution (#462).

Shape layers are always continuously rasterised, as in After Effects and
as text layers already are here: the contents are drawn at the layer's
effective scale (own transform and parents) whether or not the
Continuously Rasterize switch is on, so scaled-up shapes stay sharp.
Fixes#751

Problem: a movie whose profile the software decoders lack (H.264 High 4:2:2 / 10-bit)
probes fine, then every frame read fails; MediaPool logged the error per frame and returned
None, so the layer rendered black with no sign why in the viewer, Project panel or for agents.
Fix: MediaPool records the reason once per file (codec from the probe plus the decoder's text
without error wrappers; I/O errors stay with missing-footage handling), logs it once, and
exposes it through the new FootageSource::problem. The Composition viewer shows it on the
affected layer, the Project panel marks the item with a warning whose tooltip is the reason,
and project.summary / footage.info carry a "problem" field. Cleared when the file is
forgotten; only set when decoding really failed, so a hardware decoder that handles the file
shows nothing.

Problem: scrubbing a long movie showed the frame under the pointer
seconds after the pointer stopped. Every viewer frame a free frame-pool
thread had started kept running: each seeked the movie's one decoder and
decoded up to a GOP, and the newest frame waited behind all of them on
the decoder's lock (45 min 1080p H.264/HEVC, GOP 250: 1.8-3.6 s for the
last frame of a drag; a single jump is 0.1-0.4 s). FilmCraft's decoder
already polls a cancellation flag, but nothing set one.
Fix: FootageSource::cancellable / called_off and CancellableFootage (a
per-render view whose frame reads run under the render's own flag, so
reads on other threads answer to the right render). MediaPool runs them
under filmcraft_media::cancel::with_cancel. The frame workers render
through it, and a newer viewer frame calls off the comp's running viewer
frames of other times. A called-off render is not cached (frames, disk,
layer cache). Drag latency is now 0.1-0.3 s.

Problem: with no working space and Working Gamma 2.4, a linear EXR still
converted with the sRGB curve (0.18 -> 0.4627, After Effects 0.4902):
float footage was sRGB-encoded at decode, before the render knew the
project's curve. Interpret As Linear Light on float footage then encoded
a second time (0.18 -> 0.7255).
Fix: FootageSource::frame_with asks for float footage with a FloatCurve
(sRGB, a pure 2.4 power curve, or as stored). The renderer asks for the
Working Gamma's curve when unmanaged, sRGB when managed, and the stored
values when Interpret As Linear Light encodes them afterwards.
MediaPool decodes float values that way (Preserve RGB still reads them
as stored) and caches each curve apart.

An authored layer's effect buffer spanned only its painted content — the glyph
bounding box for text, the drawn bounds for shapes — while the size the stack
measures from (effect_bounds) is the whole comp-sized layer rectangle. Tiling
and displacement effects computed correct output for pixels outside the painted
rectangle and then wrote them into the buffer that was too small, so CC Tiler
repeated only within the text box and CC Smear lost its liquid trail at the
glyph edge (#658). Buf::cover now grows the stack's input to the layer's
rectangle with transparent margins — what a sized source's buffer already is —
applied by run_effect_stack whenever an enabled video effect will run, and
natively on the GPU by reallocating and copying the texture. The placement and
the sized-source paths are unchanged; two regression tests (CC Tiler spans the
region, CC Smear trails past the text bounds) fail without the growth.
After Effects' `app.project.workingGamma` (2.2 or 2.4, ignored with a working space) sets
the curve an unmanaged project uses: at 2.2 the piecewise sRGB curve, at 2.4 a pure 2.4
power curve. EffectCraft always used sRGB, so linear EXRs (Interpret As Linear Light) from
a 2.4 project came out darker in the shadows (0.18 → 0.461 instead of 0.490).
- `ProjectSettings::working_gamma` (default 2.2, serde default for old projects).
- The colour pipe's unmanaged curve is the Working Gamma's (sRGB, or Rec. 709's pure 2.4
curve): Interpret As Linear Light encodes untagged footage with it and Blend Colors Using
1.0 Gamma linearizes with it; it is part of the pipe's cache key. The GPU path takes the
same conversions.
- `file.projectSettings {workingGamma: 2.2|2.4}` (other values are refused, as in AE),
`app.project.workingGamma` in scripts and a Working gamma choice in Project Settings.
Test: render test with linear 0.051 / 0.18 / 0.5 footage (0.290 / 0.490 / 0.749 at 2.4,
0.250 / 0.461 / 0.735 at 2.2, the values measured in AE), linear blending at 2.4, a working
space ignoring the setting, and the cache key.
