- 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.

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.
