- Exported HEVC/AV1 nclx says BT.709 and limited range where the pipeline
means it, matching what the players we tested assume; the round-trip
tests pin the box values.
- The ffmpeg oracle helpers no longer read the flags column of
`ffmpeg -decoders` for "is a decoder" — every row of that listing is a
decoder, and the trailing D there is "supports direct rendering method
1", which a build's hevc decoder may legitimately lack. Decoders are
matched by the codec-name column alone.
- Fixtures a given ffmpeg build cannot actually encode (a listed encoder
that fails at run time: hardware backends without their device, the
noopenh264 stub) skip with a note instead of failing the run.
Accelerator::comp_frame_yuv420 (default None) renders a top-level comp frame and
converts it over the background to the H.264 export's 8-bit BT.709 limited-range
4:2:0, every byte within one level of the CPU conversion (the GPU kernel follows
it operation for operation, including NaN and half-away-from-zero ties, but a
driver may contract its arithmetic). A 4K frame then reads back 12 MB of planes
instead of 133 MB of RGBA f32.
The H.264 export asks the accelerator for planes when a frame needs nothing after
the render (progressive, project depth, no crop/resize, rendered at the output
size) and otherwise renders and converts on the CPU as before. Deferred
readbacks (a browser worker) keep the pass-based path. Sizes the kernel can't
take (width not a multiple of 8, odd height) are declined before any GPU work.
Like Cx::frames, h264_frames caps GPU frames in flight only while the
accelerator is up (map_frames_while with the same liveness check): once the GPU
stops for good, the remaining frames render on the CPU side by side instead of
one at a time.
rgba_to_yuv420 moves to effectcraft_raster::yuv so the export and the GPU tests
share one reference. The GPU tests skip without an adapter (tests::gpu()), as
the crate's others do.
H.264 and ProRes exports of a 60-frame comp (several render batches, a
rotating stroked ring, a fading solid at a fractional position, a
Screen-mode shape, 8 bpc) must keep the exact bytes main wrote before the
two previous commits.

Movie exports (H.264, HEVC, AV1, ProRes, uncompressed) rendered a batch of
frames on every core, then encoded it frame by frame while the render
threads waited. Each batch now encodes on a pool shared by all exports while the
next batch renders (Cx::frames_beside). With deferred GPU readbacks, or
where no thread can be started (wasm without threads), the two still take
turns. A panicking encoder becomes an export error.
H.264 frames are converted to 4:2:0 on the render threads, per frame, instead
of on the encoder's critical path. The conversion reads 8-bit levels from a
table and rounds without a libm call; both give the same values as before
(tested against the previous formula).
Demo comp (1920x1080, 300 frames) to H.264 on a 16-thread Ryzen, export
wall time -6% (median of 7 interleaved runs); output byte-identical.

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.
Poison recovery, OsStr::to_str and char predicates only; S4325 casts are
f64 to f32 and stay.

Review of #1763:
- With EFFECTCRAFT_CPU_INFLIGHT set, each window is the CPU cap instead of
one frame per thread, so rendered images held before encoding count
against the cap too (a cap of 2 on 16 threads held up to 16 images).
- Once the GPU stops for good, the GPU cap lapses and the CPU cap alone
applies, instead of the smaller cap (often the GPU default of 1) holding
for the rest of the batch.
The caps are now an `Inflight { gpu, cpu }` that `map_frames_while`
re-evaluates per window and chunk.

CPU renders kept one frame per thread in flight with no cap, so heavy comps
could be OOM-killed. EFFECTCRAFT_CPU_INFLIGHT=N renders at most N frames at
once through the existing capped path; unset keeps today's behaviour. With a
GPU cap too, the smaller cap holds for the whole batch.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- The cap applied whenever an accelerator was attached, so Software Only
projects (which render on the CPU) rendered one frame at a time. It
now needs the project's GPU acceleration too, as #898 gates it.
- Only the render is capped: each window of max(cap, threads) frames
renders in chunks of the cap, then encodes in parallel, holding at
most one window of images.
- An invalid EFFECTCRAFT_GPU_INFLIGHT (0, negative, not a number, too
large) logs a warning before using the default.
- The default stays one frame: the GPU backend reports no free or total
device memory portably, so it is not sized from VRAM.
Three frames at once still filled an 8 GB card on the #879 project at
1080p (7.9 GB, the same as no cap); one frame peaked at 6.3 GB and two at
7.0 to 7.8 GB. One matches how the export scheduler in #898 renders image
sequences (one GPU worker, synchronous readback). EFFECTCRAFT_GPU_INFLIGHT
still raises it.
With a GPU accelerator every frame of a batch rendered in parallel, each
holding its own working textures, so a 30-frame 1080p batch could take
the whole card (20+ GB on an RTX 3090) and run shared-memory GPUs out of
memory. Cx::frames now renders GPU frames in consecutive chunks of 3
(EFFECTCRAFT_GPU_INFLIGHT overrides it), the same cap as the export
scheduler in #898; output order and the CPU path are unchanged.
Fixes#879
Problem: the Render Queue had no single-file uncompressed output, so
handing a render to an external encoder meant a lossy codec, ProRes,
or an image sequence plus a separate WAV.
Fix: add the "QuickTime (Uncompressed)" Output Module format. Frames
are stored as QuickTime 'raw ' samples: 8-bit RGB (depth 24, rows
padded to even bytes) or ARGB with RGB + Alpha (depth 32), written
through FilmCraft's existing QuickTime muxer with PCM audio
(16/24-bit or float) like ProRes. Format name `uncompressed` on the
control channel; disk-space estimate and Sample Format menu included.

Cause: pipeline::Cx rendered with Backend::Auto, which picks the CPU or the
GPU compositor for each top-level frame from measured frame times
(render::AutoPick: warm-up on both sides, a re-probe every 48 frames). The
two compositors differ slightly, so frames came out differently depending
on which side the timings favoured in that run, and two GPU exports of the
same frames differed.
Fix: the job renders every frame on the project's renderer, as After
Effects renders a job with one renderer: Backend::Gpu with Mercury GPU
Acceleration (frames the GPU declines still render on the CPU, as they do
in every GPU render), Backend::Cpu with Mercury Software Only. The viewer
and previews keep Auto. Docs (architecture, parity, web) say so.
Tests: render_settings::a_job_renders_on_one_compositor exports ten frames
with a stand-in GPU compositor that keeps Auto history and draws solid
green: with Mercury GPU Acceleration every frame is green and two runs are
identical (with Auto the warm-up sent frames to the CPU: it fails), with
Software Only the stand-in is never asked. The web worker GPU job test's
comment no longer describes Auto.

Cause: pipeline::Cx::render_at built the job's Renderer without a layer
cache, so every layer of every frame rendered from scratch (source, masks,
effects, styles), and the GPU compositor, whose uploads are keyed by the
cached buffers, uploaded every layer again on every frame.
Fix: each job (Cx) owns a LayerCache, the cache type the viewer uses, with
its default budget (1 GiB, the default Settings > Memory & CPU layer cache),
shared by the job's parallel frames and dropped with the job. With deferred
GPU readbacks it holds the accelerator's miss gate, as the job workers'
caches do. Cx::renderer builds the job's renderer (options, accelerator,
cache) for render_at and the test.
Tests: pipeline::tests::layers_render_once_per_job exports ten frames of a
solid animated only in Transform: the cache misses of the first frame are
the only ones (it fails without the cache: no layer is cached), and every
frame equals the frame rendered without the cache.

The Output Module offers 32 Bit Float for AIFF and the queue reports F32, but
audio_file silently wrote 24-bit PCM because plain AIFF has no float. Write
an AIFF-C file instead: FORM type AIFC, an FVER chunk (AIFC Version 1), and a
COMM chunk naming the fl32 compression type, with big-endian IEEE float
samples in SSND. 16- and 24-bit stay plain AIFF.

The EXR sequence writer and comp.saveFrameAsExr clamped colour to 0..1 before the sRGB decode, so a 32 bpc project lost every over-range value. The lower bound stays at 0 and alpha stays clamped. Tests cover Rgba and Rgb sequences and saveFrameAsExr.
AAC audio in an MP4/MOV whose sample rate differs from the mix rate
(a 44.1 kHz clip in the 48 kHz preview or export, or the reverse)
stuttered and sounded low-pitched in previews and in exported movies.
Cause: FilmCraft's MP4 reader, asked for audio at a rate other than
the file's, applied the edit list's priming offset (1024 samples for
AAC) twice when it resampled: each read started about 1024 source
samples early and extrapolated a ramp over its first ~940 samples
(peaks near 100 against a 0.5 tone). Export and the preview mix ask
for audio a frame or a device buffer at a time, so the ramp repeated
dozens of times a second. Same-rate reads take FilmCraft's copy path
and were exact. FilmCraft fixed this upstream in 5bf2203, 87 commits
past the pinned revision.
Fix: MediaPool reads footage audio at the source's own rate and
resamples it itself (linear, by absolute sample position, so a range
comes out the same however it is split into reads), for every
container.
Test: resampled_audio_read_in_frame_pieces_matches_ffmpeg (44.1 kHz
AAC read at 48 kHz and 48 kHz at 44.1 kHz in 29.97 fps frame pieces,
against ffmpeg's decode: max error 44 before, 0.002 after) and
movies_carry_resampled_footage_audio (a 29.97 fps comp with 44.1 kHz
AAC footage exported to MP4/AAC and MOV/PCM, decoded by ffmpeg: max
error 8.7 before, 0.03 / 0.002 after).

A frame whose last byte happened to match the superframe marker pattern
(0b110xxxxx, Annex B) was taken by decoders for a superframe with an
index at its end: ffmpeg rejected it ("Invalid le value at
frame_sizes[i]"), libvpx reported a corrupt frame, and later frames lost
their reference. In the reported WebM, 3 of 60 frames (10, 22, 24) ended
in 0xc8, 0xc0 and 0xca. The render still reported success.
Such frames now get a zero byte after the last tile; the last tile's
bool-coded data may end in zero padding (9.2.3).
Test: frames_never_end_in_a_superframe_marker encodes sequences until a
frame needs the padding, checks no frame ends in a marker byte, and that
the padded frames decode exactly with FilmCraft's decoder and with
ffmpeg (clean error log). It failed before ("96x64 q40 frame 22 ends in
0xde"). The ffmpeg IVF oracle is shared with the existing inter test.
Checked with the reporter's steps: 60/60 frames, no errors from ffmpeg's
vp9 or libvpx, RGB and RGB + Alpha.

These crates have no production panic sites: add the deny attribute so they stay clean
(geom, color, model, automation, host, export, plugin, and the desktop, CLI and web apps). The
plugin's wasm-only test module gets a separate cfg(test) attribute so clippy recognises it as
test code.

- GPU in browser job workers: each job worker opens its own WebGPU device
(deferred readbacks); the Render Queue export and the analyses' frame loops
are futures (render::passes, offload::run_request_async) whose frames
render in passes, awaiting the device between them. GPU particles and
Advanced 3D read back under keys too. workers.jobs reports passes and
readbacks; the smoke test measures them.
- Layer buffers in the browser's OPFS disk cache: frame workers back their
layer caches with a PrefetchStore; the page plans what to fetch before a
request from recent misses (LayerPrefetch over the shared DiskIndex).
- Templates embed footage (default on, size-capped with a warning) and
creating from a template extracts it next to the new project / into
browser storage.
- ICC LUT profiles (lut8/lut16/lutAtoB/lutBtoA, from the public ICC spec) in
Simulate Output > My Custom RGB, baked into a 3D LUT for the viewer.
