Text layers: the name follows the text until the user renames the layer
2026-11-08 15:44:58 +01:00
vangel76 5f73e5b5e9 Time stretch: hold a loaded or imported stretch to ±1 % to ±9900 %
A project file, an .aep, a timeline document or a Lottie file could give a
layer a time stretch of 1e-300 %, 0 or 1e300 %. Layer and comp time divide
by it and the audio mix read about usize::MAX source samples for one block,
which overflowed or tried a huge allocation and aborted the app.

- limits::stretch brings a stretch within After Effects' range (±1 % to
  ±9900 %, Layer.stretch in the scripting guide), sign kept; 0 and NaN are
  100 %. Opening a project file corrects each layer and says so; a stretch
  written as null (NaN in an auto-save) now opens instead of failing.
- .aep import and Lottie import clamp and report the stretch; timeline
  import clamps the clip speed and warns.
- layer.timeStretch refuses a non-number and more than 9900 %; the Time
  Stretch dialog's ranges match.
- Layer::layer_time / comp_time and the audio mix use the clamped stretch,
  so a value set in memory can't divide by zero or read without bound.

vangel76 61af9e5b72 #3233: a text layer's name follows its text until the user renames it
A text layer's name followed its Source Text whenever the name started with "Text", so a user's
"Text Title" was replaced by the next text edit. The layer now records whether its name follows
the text (`name_follows_text`, optional in the project file). A new text layer named after its
text follows it; a name given at creation or by Rename (Enter, layer.rename, a script's
layer.name, Layer Settings' name) is the user's and stays; renaming to an empty name shows the
text again and follows it; committing the unchanged name changes nothing; copies keep the state.
On-canvas typing and layer.setText share the rule. The name is the text's first paragraph, which
ends at a line feed or a bare carriage return (After Effects' paragraph break).

Projects saved without the state keep the old rule for the names that followed: a name that is
empty, the text's own, or "Text"/"Text 2"... follows; any other name stays. AEP import records a
stored layer name as the user's and no name as following, and names an empty text layer without
a name "Text" instead of "Layer"; export writes no name for a following layer and keeps the name
the user gave, even when it equals the text.

611a282bea Plug-ins: external effect helpers (safe, out-of-process native effects) + plug-in API 2 (#889)
* Plug-ins: API 2 (PluginHost, padding, layer_span)

Split out of the OpenFX work so it can be reviewed on its own. Additive; the WebAssembly ABI
stays at 1.

- point3 / layer / text / hidden parameters, integer sliders, parameter groups.
- EffectPlugin::padding (transparent pixels around the buffer, at most 4096 per side).
- EffectPlugin::render_v2 with a PluginHost: the input at other times, other layers, parameters
  at other times, frame rate, per-instance key, the layer's source range.
- EffectEnv::layer_span from the renderer; MAX_PLUGINS 1024.
- plugin_error: a plug-in effect's last render error, for the UI.

* Plug-ins: external effect helpers (crates/helper-host)

Native plug-in formats run in separate helper programs, never in EffectCraft's process
(docs/adr/0001-external-effect-helpers.md). New safe-Rust crate effectcraft-helper-host (L3,
native only, unsafe forbidden): it finds helper programs, starts each as a child process and
registers its effects through plug-in API 2, so the UI and command surface need nothing new.

- Protocol v1 (docs/external-helpers.md): JSON lines over stdin / stdout (helper replies are
  prefixed so plug-in chatter is ignored); pixels go through a frame exchange file (/dev/shm on
  Linux), never through the pipe. Render-time callbacks for the input at other times, other layers
  and parameters at other times, with nested renders through the same helper.
- A helper that exits, hangs past its timeout or breaks the protocol is stopped. The render fails
  with a message, the frame is left as it was, and the helper restarts for the next render. An
  effect that stops its helper 3 times is turned off (helper_blocklist.txt).
- Opt-in: nothing starts helpers unless the user asks (Effect > Scan for Effect Helpers), or opts
  in to starting them at launch with EFFECTCRAFT_HELPERS=1, an environment variable, so writing
  to the settings folder alone can't run code. effect.helpers.scan / load are refused for
  confined agent sessions (confine.rs), like file.executeFile.
- Discovery: helpers/ next to the app (Contents/Helpers on macOS), helpers/ in the settings
  folder, EFFECTCRAFT_HELPER_PATH.
- Commands effect.helpers.list / scan / load; Effect menu entries (translated); the last render
  error of an effect shows as a warning sign after its name in Effect Controls.
- serve(): the helper side for Rust helpers. tests/it/main.rs runs the whole protocol (render,
  padding, callbacks, nesting, threads, crash, restart, block list, hang) against a fake helper,
  with nothing to install.

* Effect helpers: address review (start failures, frame file mode, nextest listing)

- A helper that can't start (not installed any more, restarting too often, no frame exchange
  file) is reported but no longer charged to the effect being rendered: it is Failure::Refused,
  not Failure::Broken, so it never counts toward turning that effect off. New check in
  tests/it: once the helper is out of restarts, renders of an effect fail without blocking it
  (fails without the fix: the effect was turned off after 3 such renders).
- The frame exchange file is created owner-only (0o600) on Unix: it holds the user's frames and
  /dev/shm is shared. Asserted in the frames unit test.
- tests/it (harness = false) speaks the libtest listing protocol cargo-nextest uses:
  `--list --format terse` prints `helper_protocol: test` (nothing with `--ignored`), and
  `helper_protocol --exact` runs the checks.

* Effect helpers: bound writes to a helper, drain stderr, keep callbacks in step

- Writes to a helper go through a writer thread with the request timeout: a
  helper that stops reading its stdin (hung with a large callback answer or
  render request pending) no longer blocks the render thread forever while
  holding the helper.
- stderr is drained as bytes (lossy, in 64 KiB pieces) to the end: output that
  isn't UTF-8 stopped the reader, closing the pipe under the helper (EPIPE /
  SIGPIPE on its next write); lines were unbounded.
- Callback images that can't be written are answered with `null` instead of
  failing the render while the helper waits (which left the protocol out of
  step); a frame that can't be written before the request is sent is not
  charged to the effect.
- Mid-render calls use the render's own process: no respawn or heartbeat ping
  while the helper is waiting for an answer.
- Waiting for a busy helper is bounded (load timeout) instead of forever;
  status() no longer blocks on a running render.
- Reap the child when start-up fails after spawning; cap the block list read.
- Scripts start helpers only with Allow Scripts to Write Files and Access
  Network on (they run native code), as for File.execute().
- helper-host declares the workspace's no-panic crate lints; the desktop
  main() keeps its doc comment.

* Effect helpers: rustfmt the fake provider, build the test session in its initializer (clippy)

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Plug-in Library: offer WebAssembly API 1 releases only; a helper already stopped mid-render isn't charged again

- WasmPlugin loads only modules at the WebAssembly ABI version, which stays 1 while
  PLUGIN_API_VERSION is 2: share it as effects::plugin::WASM_API_VERSION and have the
  library's compatibility check use it, so it never installs an API 2 release that
  can't load.
- with_running: a process that is already gone was stopped by what broke it (a nested
  render, charged there), so this render fails without charging its own effect.

* frames: plug-in effects count as reading other frames (plug-in API 2)

With main's narrowed frame invalidation (#2795), an edit inside a precomp under an
effect that reads its layer at other times must reach the layer's whole span.
Plug-in API 2 gives every plug-in effect the input at other times, so any effect
outside ec. counts.

30d6c6e1d3 Frames cache: edits keep the frames they can't reach (#2795)
* frames: keep cached frames an edit can't reach

Nudging, trimming or splitting a layer re-rendered the whole comp. The RAM
preview now carries every frame whose stack of active layers is unchanged
to the new comp identity; only the segments an edit touches re-render.

* disk cache: never drop frame writes; save frames kept after edits

Frames get their own write lane (bounded by bytes, written before layer
buffers), so a burst of layer writes no longer drops frames and leaves gaps
in the blue bar after reopening. Frames an edit kept in RAM are written to
disk under the comp's new content key when idle.

* frames: music and hidden layers keep the caches

Layers that can't change pixels (audio-only footage, AV layers with Video
off, when nothing reads them and there are no expressions) no longer count
for the RAM preview's dirty segments or the disk cache's comp and footage
keys. Adding, trimming or moving music keeps both caches.
RENDER_VERSION bumps to effectcraft-render-3 for the new key formula.

* ui-egui: background caching benchmark

cache_bench fills a comp's RAM preview the way idle caching does and
prints frames/s with decoder, footage-cache and disk-cache counters.

* frames: soloed music and hidden layers aren't silent

Solo hides every other layer, so soloing a music track or a layer with
Video off changes the picture. silent_layers no longer drops soloed
layers, so the RAM preview and the disk cache see Solo toggles.

* disk cache: audio files a layer reads stay in the layer salt

Audio-only footage left the disk layer salt so importing music keeps the
keys, but Audio Spectrum and Audio Waveform draw from an audio layer.
Footage another layer reads (or any, when a read layer is a precomp)
counts again, so overwriting that file doesn't reuse stale buffers.

* disk cache: retry frame writes the queue refused

put_frame reports whether the frame is on disk or queued. persist_missing
forgets the key of a refused write, so a full frame lane no longer leaves
RAM frames that are never written.

* ui-egui: cache_bench measures idle caching; checks --comp and --slots

Frames go through request_background with one slot per frame thread, as
Cache Frames When Idle does. An unknown --comp is an error (the active
comp is used only without --comp), --slots is at least 1, and the disk
report flushes queued writes instead of sleeping.

* disk cache: RENDER_VERSION effectcraft-render-6

This branch changes the cache-key formula (silent layers, Solo, read
audio in the footage salt), and upstream #2759 already took render-5
for the clip-clock change, so entries from either must not be reused.

* frames: rewrite RAM frames the disk cache evicted

persist_missing kept every disk key it ever queued, so a frame the disk
cache evicted later was never written back. The disk cache now tracks
frame writes still queued or in progress (frame_pending), and
persist_missing only remembers keys while it converts them.

* frames: idle passes continue while RAM frames wait for disk

persist_missing reports whether there may be more to write (a content key
being computed, frames being converted). Cache Frames When Idle then
schedules another pass, so a refused write is retried without waiting for
a UI event, and the passes stop once every frame is on disk or queued.

* frames: rewrite an evicted frame once, not on every idle pass

A disk cache smaller than the RAM preview, or a frame too large for it,
made idle passes write, evict and rewrite the same frames every 500 ms.
Each disk key is now written at most twice under one disk limit (the
write and one rewrite after an eviction); a new limit resets the count.
The persist test waits for the conversion to forget its keys before
checking that no work is left.

* frames: the work area doesn't change pixels

Setting the work area (B, N) cleared every cached frame, in RAM and on
disk: it was compared with the comp's pixel settings and hashed into the
disk key. It is a preview and render range only, like the Resolution, so
it no longer counts.

* frames: audio edits keep frames unless something draws the audio

Changing a clip's Audio Levels, its audio effects or its Audio switch
cleared the clip's cached frames, and the comp's disk cache, although
nothing drew that audio. The audio now counts only for the layers whose
audio is heard (Project::heard_layers): those a layer picks in an effect
(an Audio Waveform or Spectrum, even on itself), the layers of a picked
precomp, and every layer while an expression (which can read Audio
Levels) exists. Music in a precomp that a waveform in the outer comp
picks is no longer treated as silent either.

* frames: an expression only reaches the frames of its own layer

One expression anywhere in the project made every edit clear the
comp's whole cache, and so did editing a layer another layer reads
(its parent, matte, or a layer it picks). Expressions can read
anything, but they only draw in their own layer: an edit now re-renders
the frames where it changed something, plus those of the layers with an
expression and of the layers that read a reached layer. With
expressions, an edit elsewhere (another comp, an item's name, a marker,
music) reaches only the expression layers' frames.

* frames: an edit inside a precomp re-renders only where the precomp shows it

Editing anything inside a precomp cleared every cached frame of the
comps that nest it, even a music level in it. Project::dirty_spans now
follows precomps: it takes the spans their comp changed in, shifts and
scales them by the precomp layer's start and stretch (its whole span
under a time remap or Responsive Design timing), and keeps the outer
comp's other frames. Layers that read a changed precomp (a matte, a
waveform) re-render where they are active.

* disk cache: keep the frames an edit can't reach

The disk cache keys frames on a hash of the whole comp, so every edit
lost the frames that were only on disk (the blue bar), even a rename;
only those still in RAM were written again under the new key. When an
edit keeps RAM frames, it now also queues a disk carry: on the frame
pool, each kept frame of every disk series in use for that comp is hard
linked (or copied) to its new key with DiskCache::link_frame, oldest
edit first. The old entries stay, so undo finds them too.

* frames: a keyframe edit re-renders only around the keys it changed

Changing one keyframe (its value, interpolation or ease, in the
Timeline or the Graph Editor) re-rendered the layer's whole length, so
a key on a full-length layer cleared the whole cache. A layer that
differs only in keyframes of its Transform properties now re-renders
from two keys before the first changed key to two after the last
(auto-Bezier and continuous tangents reach the neighbouring segments),
to its in or out point past the first or last key. Static values,
expressions, roving keys, time remap and time effects still reach the
whole layer; effect keyframes do too for now (simulations and time
effects read other frames).

* frames: music volume keeps frames while no expression reads audio

Any expression in the project (a wiggle on another layer, even a
disabled one) made every layer's audio count as read, so changing a
music layer's Audio Levels re-rendered every expression layer and
changed the comp's disk key. Audio now counts for expressions only when
one may read it (Heard::audio_exprs): its text names audio or walks
properties by index. An audio-only change nothing reads no longer counts
as a change elsewhere in dirty_spans either.

* frames: a keyframe edit with few keys or beside a self-contained expression keeps the other frames

Changing a Scale key of a layer with two or three keys re-rendered the
layer's whole length: with fewer than two keys before (or after) the
changed one, the span fell back to the in (or out) point instead of the
first (or last) key, past which the value holds. And any layer with an
expression re-rendered on every edit, so a wiggle on a full-length layer
cleared the whole cache. An expression layer is now reached by edits
elsewhere only when its text may read outside its layer (it names a
comp, layer, footage, the project or its source); its parent and the
layers it picks are still read through referenced_layers.

* viewer: the caching chip stays up between uncached frames, with a spinner

The "Caching frames…" chip showed only while playback waited for a
frame, so during caching it flickered on and off with every frame that
arrived. It now stays up 0.6 s after the last wait (and hides at once
when playback stops). It is also smaller and quieter: a spinner, then
"Caching frames" without the ellipsis in dimmed smaller text, on a
fainter chip sized to its text.

* preview: the Preview panel's cache bar counts the preview's Resolution

With a preview Resolution set (Half, Third…), the frames a preview
plays are cached at that scale, but the Preview panel's bar counted the
series the viewer shows. When playback stopped, the viewer went back to
the comp's Resolution and the bar dropped from full to the frames cached
there. It now counts the preview's own series (Auto still follows the
viewer). The viewer and the Timeline's cache bar are unchanged.

* Contributors: add nazar-gavrylyk's name

* frames: an expression reading its own layer's markers or audio re-renders that layer

With expressions in the project, a layer's markers count when comparing it, and its audio counts
when an expression may read audio, so a marker or volume edit re-renders the edited layer over
its own span. Comp markers still count only through layers whose expressions name thisComp.

* frames: a keyframe edit on a layer with an expression re-renders the layer

An expression on the keyed layer can read the keyed property at other times (Rotation reading
Position with valueAtTime), so the frames past the changed keys may change too.

* cache_bench: read decoder counters through effectcraft-media

Only crates/media, crates/export and crates/interchange may depend on the FilmCraft crates.

* cache_bench: clips end where the next one starts

* frames: write-back uses the worker's disk keys while a Roto Brush model is active

persist_missing keyed disk frames on FrameKey::opts, which also carries the Roto Brush model
stamp; the worker and disk_frames key on the render opts' hash alone. With a model active every
RAM frame looked missing, was written again under keys nobody reads, and recorded a second disk
series.

* frames: an edit two precomps down reaches the outer comp

A precomp layer whose comp Arc didn't change was skipped, but the comps nested in it may have
(an edit in Inner leaves Mid's Arc as it was), so Outer kept every frame. Every nested comp is
walked now, each once per edit.

* cache_bench: stop when the disk cache can't be cleared

* frames: one disk carry job at a time

carry_disk runs on every timeline paint and idle pass, and spawned a pool job whenever carries
were queued; during a drag the extra jobs waited on the carry lock and held frame-pool threads
from the viewer. A scheduled flag keeps one job, which drains the queue in order until it's
empty.

* frames: a panicking disk carry is skipped, not left holding the job

The carry job clears carry_scheduled only on its normal exit; a panic in a carry would have left
it set for the session, so no later carry ran. Each carry is caught like the content key's
hashing, so the job always reaches its exit.

* frames: an expression reading its own in point or index re-renders its layer

A trim or rename kept the layer's frames outside the cut when the layer
drew the same apart from its span, but an expression on it can read its
own inPoint, outPoint or name (a fade from inPoint), so every frame of
the layer changes. Such a layer is no longer treated as only respanned.

An expression reading `index` reads the layers above it too: a layer
added or removed there shifts it, so `index` now counts as reading
outside the layer.

* frames: an edit of a comp reaches the expressions of the precomps it nests

An expression in a precomp can read the comp that nests it
(`comp("Main").layer("Controls")`), but the walk into nested comps only
counted changes outside the edited top comp. Editing a hidden Controls
layer there (or any layer, when the precomp is time-shifted or reads it
at other times) kept every precomp frame in RAM and linked them all on
disk under the new key. Nested comps now see an edit of the comp above
them as an edit elsewhere.

* frames: an edit in a precomp under a time effect reaches its whole layer

A precomp layer running Echo, Posterize Time, Time Displacement or
another effect that reads the layer at other times shows a nested change
far from where it maps, but only the mapped span (a nested frame either
side) re-rendered. Such a layer now gives its whole span, like a time
remap. `reads_other_frames` lists those effects (every `ec.time.` and
`ec.sim.` effect and the others that call `self_at`); keyframe spans use
it too.

* frames: a keyframe edit beside muted keys re-renders the whole layer

Muted keys are skipped when a property is evaluated, so the keys that
play around an edited key can be any distance away, but the span counted
two stored keys either side. A segment from an earlier playing key kept
its stale frames. Muted keys now give the layer's whole span, like
roving keys.
