Settings ▸ Project ▸ Project Files ▸ Save Compact Project Files (off by
default) saves .ecproj files as compact JSON: smaller, faster to save and
open. Off, they stay indented, one value per line, so they read and diff
cleanly in version control. XML copies are not affected; auto-saves were
already compact. The project.ecproj inside exported template and Motion
Graphics template packages is written compact.

Conflicts came from upstream splitting crates/project/src/lib.rs and moving the
frames tests. Re-applied the branch's change in the new places:
- Layer::same_pixels_with now in crates/project/src/layer.rs
- Comp::same_pixels_with, same_settings(o, with_markers), pixel_form_with and the
timing-marker helpers in crates/project/src/comp.rs (same_pixels_ignoring_markers
stays removed)
- Project::reads_markers in crates/project/src/item.rs
- crates/ui-egui/src/frames.rs uses reads_markers/same_pixels_with; the branch's
two marker tests replace the old ones in crates/ui-egui/src/frames/tests.rs

render: upstream moved the tests_*.rs modules into crates/render/src/tests/; the branch's
tests_mask_feather.rs now lives at tests/mask_feather.rs and is registered in tests.rs.
path: rect() keeps the branch's explicit-outline version with an added NaN guard on the
roundness clamp bound (main's fix for the same panic).

After Effects lists Targa among its still-image output formats; EffectCraft
imported Targa (#745) but could not render to it.
- OutputFormat::TargaSequence ("Targa Sequence", `.tga`, numbered like the
other sequences; `tga` / `targa` as a format name or output extension).
- Written by the `image` crate's Targa encoder (its `tga` feature, already
enabled in effectcraft-media; no new crates, Cargo.lock unchanged), with
run-length compression off: an 18-byte header, top-left origin, 24-bit BGR
for RGB, 32-bit BGRA with 8 alpha bits in the image descriptor for
RGB + Alpha (straight or premultiplied), 8-bit grey for Alpha.
- The render queue's size estimate counts the uncompressed bytes.
- CLI usage, the renderQueue command specs, README, architecture.md and
file-format-parity.md name the new format.
Tests: each Targa frame holds exactly the pixels of the PNG sequence of the
same job, with the expected header, numbering and size; the frames read back
through the Targa importer as the same picture (straight, and premultiplied
when interpreted so); the image-sequence round trip, the format parser and
the renderQueue commands cover it too.
upgrade_shape_contents now visits nested groups with a work list, so a
project with very deeply nested shape groups does not run out of stack
while Wiggle Paths gains Spatial Phase. The new test nests a Wiggle
Paths 100,000 groups deep and upgrades it on a 2 MiB stack.
Wiggle Paths had Size, Detail, Points, Wiggles/Second, Correlation,
Temporal Phase and Random Seed, but no Spatial Phase, which After
Effects lists among its properties (ADBE Vector Spatial Phase). Spatial
Phase now moves each point's own displacement along its subpath: 360
degrees is once around, and a fraction of a point is interpolated
between neighbors. At 0 degrees a path draws as before.
A project saved without the property gets it at 0 degrees, after
Temporal Phase, when it opens. Scripts can read and set every Wiggle
Paths property by its match name.
Conflicts in project/src/lib.rs and ui-egui/src/frames.rs: Comp::same_settings
takes with_markers and is shared by same_pixels_with and changed_span (#1641);
frames identity uses same_pixels_with/reads_markers and drops
same_pixels_ignoring_markers and project_has_expressions.

- New `crates/project/src/file_check.rs`: a no-output `Serializer` that walks the value once. It refuses non-finite numbers and nesting past 127 levels, and it allocates only on error.
- `to_file_json_with_view` runs that check, then writes the file. It also refuses a project schema newer than this build, the remaining thing `from_json` would reject in a file we wrote.
- **Debug builds still reparse the text as well**, so a new kind of mismatch still shows up in tests.
The bytes written are unchanged.

The Smooth feather is three separable box passes of 2 round(0.37 F) + 1
pixels (a quadratic B-spline reaching ~1.11 F either side), fitted to
After Effects 2026 renders of feather 100, 300 and 1000 (rows, columns,
corner diagonal, case 398): max error under 1/255, where a Gaussian of
any width misses by 3/255 or more (it was sigma = F / 2). The coarse
grid for wide feathers picks the step whose three windows add up
closest to the full-resolution ones. Linear is unchanged (unmeasured).

Layer times were already saved and read back as exact ticks; the values in
the issue are 34f, 315f and 3033f at 59.94 fps. The viewer was black because
the playhead wasn't saved: a reopened comp started at 0, before its layers.
The project file's view (`activeComp`, `openComps`) now also records each
comp's current time (`compTimes`), restored on open within the comp's frames.

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.

The RAM preview keyed every frame by one identity of the whole comp, so any
edit (a cut, a trim, a nudge) made every cached frame a miss and the whole
comp recached. When only some of a comp's layers change, frames outside their
In-Out span now move to the new identity. Settings changes, reorders,
expressions, and edits that reach other layers (parents, track mattes, effect
layer pickers) still recache everything.

The roi quad is stored raw from the control channel (crop.useRoi passes
serde_json's [f64;4] straight through, unlike the sibling edge fields,
which are clamped to plus/minus 20 000) and nothing repairs it on load.
Crop::edges converted it with round() as i32 and subtracted raw: an x of
-1e12 saturates to i32::MIN and w as i32 - l overflows in debug builds,
wrapping to a wrong-but-bounded crop in release.
Clamp each converted edge to the same plus/minus 20 000 the sibling
fields use and subtract with saturating_sub in edges() and frame_size().
Regression test: hostile_roi_cannot_overflow_crop_math — panics at
crates/project/src/render_queue.rs:774 on main; with the fix the hostile
quad degrades to a 1x1 frame and the sane-ROI behavior is unchanged.
Project::comp_contains recursed through precomp layers with no visited
set or depth limit. A damaged project with a precomp cycle that doesn't
pass the queried comp (A and B nesting each other, C unrelated) recursed
until the stack ran out, which aborts the process ("stack overflow,
aborting"): it can't be caught as a command error, so unsaved work is
lost. layer.addItem checks it before adding a precomp, and the renderer
calls it for every nested comp and its audio. A long chain used the
stack the same way, and comps shared by many paths were walked once per
path (exponential for nested diamonds).
It is now an explicit stack with a visited set: same answers (a comp
contains itself; a target reached through a cycle is found), each comp
visited once, no recursion. The renderer already skips a precomp that
contains the comp being rendered, so a cyclic project now renders
instead of crashing; nothing is repaired on load.
Tests: project comp_contains_ends_on_cycles_long_chains_and_shared_
precomps (cycle with an unrelated target, self-nesting, a target through
a cycle, 40 levels of diamonds, a 20 000-comp chain); engine
a_project_with_a_precomp_cycle_opens_adds_and_renders_without_running_
out_of_stack (file.open, layer.addItem both ways, render). On main the
engine test aborts with a stack overflow.

pixel_form_with borrowed the comp unchanged when it held only comp markers and no layer
markers, so a lone plain comp marker still reached the disk key. Tests: a lone comp marker
keeps the key; a protected marker with a duration (and its duration) on a stretched precomp's
source changes the key of the comp that nests it.

Upstream's #1167 fix and this branch both stop marker edits from invalidating
cached frames. Kept this branch's shared Project::reads_markers/same_pixels_with/
pixel_form_with (viewer frames, disk cache, nested comps) and folded upstream's
rules into them: any expression counts as reading markers, protected time
markers with a duration still change the frames.

Adding a marker replaced the comp, so every cached frame stopped matching and the preview had to
re-render before its audio could carry on. Plain markers change no pixels; protected time markers
with a duration still do (Responsive Design). Markers count in full again when a project uses
expressions, which can read them.

Guides can store a percent of the comp so they follow comp-size changes
(View > Add Percentage Guide, Convert Guides to Percentage / Pixels); an
effect instance has an optional colour label (effect.setLabel, Effect Controls
header bar and Label menu). Both are serde-defaulted, so old projects load.

Project::reads_markers and Comp::pixel_form_with are shared by the RAM and disk frame caches.

Markers counted as pixels in a comp's frame identity, so every marker edit
dropped the cached frames; the playing preview then hit an uncached frame
and stopped its sound. They now count only when an expression mentions markers.

File > Import > EffectCraft Project (and .ecproj/.ecprojx given to File > Import)
merges the project into a folder named after the file, with every id shifted past
the open project's, in one undo step. Relative footage resolves next to the file;
the result lists comps, root comps, primaryComp and missing media.
offset_ids now shifts tracker Motion Targets and saturates instead of overflowing;
fix_next_id saturates too, so a damaged file can't overflow on open or import.
Menu entry translated in all ten menu catalogues.
Rebased onto current upstream main for the split of #858 (test module list in
engine lib.rs; es/pt-br/ru/fr/de/cs menu translations).

Right-clicking a footage item or solid in the Project panel offers
"Replace with Precomposition (used N times)": the item goes into a new
composition of its size, pixel aspect and frame rate, in the same folder, and
every layer in every composition that used it switches to that composition,
keeping timing, transforms, effects and masks. One undo step. Agents run it as
`file.replaceWithPrecomp`.
The Project panel's details header also shows how often the selected item is
used ("Name ▾, used 3 times"); the ▾ lists and opens the comps that use it.
`Project::item_users` and the `project.usedIn` query back both.
