Help ▸ About FilmCraft gets tabs About · Contributors · Models, following the craftrules standard
(standards/contributors.md): contributors/contributors.json is generated by
craftrules/scripts/contributors.py and baked into the binary by crates/ui-egui/build.rs as static

Export encodes H.264 on the CPU with the built-in encoder, which is most of the time
of an export (about two thirds of the busy CPU in a profile of a 20 s export). On
macOS the media engine can do it: a VideoToolbox compression session behind
`filmcraft_export::VideoEncoder`, registered by `filmcraft_platform::register()`.
- `ExportSettings::hardware_encoding` (`HardwareEncoding::Off` | `Auto`; Export > Video >
Hardware Encoding, `"hardwareEncoding": "off|auto"` in `file.exportMedia`, a boolean is
understood too), off by default: the built-in encoder's output is byte-identical on
every machine, a hardware encoder's is not.
- `videotoolbox_encode` (FFI, same containment as the decoder: SAFETY comments, no
panic across the callback, safe API) and `hardware_encode` (safe adapter and factory).
- The factory declines, so the built-in encoder is used, for other formats, MXF, two-pass
VBR, HDR, odd sizes, non-square pixels and any configuration VideoToolbox cannot create a
hardware session for. An encoder that fails mid-export stops it with an error: unlike a
decoder, it cannot hand a half-written stream to another one.
- No B-frames: on real 1080p footage the quality is the same with and without them
(+-0.3 dB at equal bitrate) and the bitrate lands closer to the target, and without
them every frame is presented at its decode time (no composition offsets, no edit list).
- `export::register_encoder` ignores a factory registered twice; `encoder_registered`.
Apple M1, 8 cores, single runs: a 9:29 timeline (camera clip, ProRes 4444 overlays with
alpha, AAC, loudness) exports in 311 s instead of 793 s (2.5x faster); its densest 134 s
in 84 s instead of 395 s (4.7x). The outputs compare at SSIM 0.990 / PSNR 46.5 dB. The encoder
alone runs 200 fps at 1080p (docs/performance.md).
Tests (tests/hardware_encode.rs): what is taken and declined, a round trip through our
software decoder, an export that decodes in our decoder and in ffmpeg, the fallback for
everything hardware declines, exact output sizes, an empty range, hostile configurations
and encoders dropped at any point; the engine's `hardwareEncoding` parameter.

New backend in crates/platform (media_foundation/): a Direct3D-aware decoder MFT is driven at the
level of single access units (Annex B), given the process's D3D11 video device through an
IMFDXGIDeviceManager so it decodes with DXVA, and its NV12 / P010 textures are read back through a
staging texture into planar Yuv8 / Yuv16. H.264 Baseline/Main/High and HEVC Main / Main 10, 4:2:0.
- Hardware is verified: non-D3D-aware or async MFTs, streams the GPU's DXVA decoder does not list,
and system-memory output (Microsoft's MFT software fallback) are declined or fail the stream so
HybridDecoder continues with our decoder.
- mfplat.dll is loaded at run time so Windows N editions still start.
- register() / registered() / hardware_decoder_for() cover Windows; perf.stats reports the backend.
- Tests (Windows): bit-exact parity with the software decoders at 640x360, 1080p and 2160p
(resets, seeks, flush), forced mid-stream failure, damaged input, concurrency, repeated init.
- Bench: runs on Windows (ffmpeg on PATH, process/thread CPU clocks), HEVC Main 10 2160p row,
hardware counters per row.

Fixes the Windows installer: the Start Menu shortcut and Add/Remove Programs icon were blank, and the shortcut description was wrong. Release builds no longer open a console window behind the app. Export can no longer panic (filmcraft-export never-crash).

- New crates/platform (filmcraft-platform, L5): OS media FFI only. The one
crate allowed `unsafe` (own [lints] with unsafe_code = "deny",
#[allow(unsafe_code)] only on the videotoolbox module, SAFETY comment on
every block, safe Result-returning public API). AGENTS.md §0.3 names the
exception; docs/adr/0001-platform-ffi.md records why and the rules.
- VideoToolbox decoder for avcC / hvcC, 8/10-bit 4:2:0 and 4:2:2: session from
the sample entry's parameter sets with hardware required, asynchronous
decode (2 in flight), biplanar CVPixelBuffer copied to planar Yuv8/Yuv16,
reorder buffer of the stream's own depth, RASL skipped after a starting CRA.
Output callback under catch_unwind.
- HybridDecoder: transparent mid-stream fallback to the software decoder
(replays samples since the last restart point, drops already-returned
pictures). New codecs::software_video_decoder (built-in factories only) and
codecs::hw (switch, counters, NalStreamInfo shared with software decoders;
vui_color / sar_par helpers now used by both).
- Settings ▸ Playback ▸ Hardware decoding: Auto / Off (engine applies it to
the codecs switch); desktop app, CLI/MCP and bench call register().
- perf.stats decode.framesDecoded and decode.hardware counters.
- Tests: bit-exact parity with the software decoders (H.264 High, HEVC Main
open GOP, Main 10; resets, reseeks, flushes), forced-failure fallback,
mutation fuzz of samples and parameter sets, cross-platform fallback with a
stand-in decoder, setting Off, HEVC 4:2:2 vs ffmpeg.
- Bench --hw auto|off; results in docs/performance.md (4K CPU/frame
~86-119 ms -> ~4 ms).

filmcraft-mxf gains a streaming writer (ST 377-1 partitions, primer, header
metadata, VBR index segments with temporal offsets, RIP; ST 378 OP1a
frame wrapping, ST 390 OP-Atom clip wrapping) for VC-3, ProRes, AVC byte
stream and PCM with start timecode and caller-supplied package UMIDs, plus
write_opatom_pcm. filmcraft-export adds mxf-op1a / mxf-opatom formats
(DNxHR, ProRes or H.264 + PCM; OP-Atom writes one mono file per channel),
presets, the engine mxfVideoCodec parameter and CLI .mxf inference.
Tests read our files back and check them against ffprobe / ffmpeg.

Shared mob-style composition model; AAF objects in structured storage over
filmcraft-cfb; OMF objects in a Bento container; embedded / consolidated audio
supplied by the caller (essence::audio_needs, MediaOptions).

- HEVC inverse transform: sum basis rows of non-zero coefficients with a
const-generic size (bit-exact, tested against the direct product);
SAO edge offset gets a check-free interior loop. HEVC CPU/frame -60%.
- H.264/HEVC/VP9 planes are moved into VideoFrames, not copied.
- Catch-up decoding: frame jobs tell sources which frames are late
(filmcraft_media::cancel::with_catch_up); the GOP cache skips
non-reference samples of late frames (H.264 nal_ref_idc 0, HEVC
sub-layer non-reference pictures). Scrubs keep the last 2 s decoded.
- perf.stats: engine query + UI/control method (decode counters,
playback shown/dropped, frame-worker decode/render ms, cache use).
- Timeline waveform source peak cached; bench seek section and --only.
- docs/performance.md with before/after results.

- assets/app-icon/: canonical SVG + light SVG, 1024 PNG, macOS runtime PNG, .icns, .ico,
hicolor theme, LICENSE.txt and README (palette, geometry, provenance, regeneration).
- packaging/icons.sh regenerates everything with resvg, iconutil and the new `cargo xtask ico`.
- Native app sets the window icon (with_icon) and the Wayland app id; build.rs embeds the .ico
and VERSIONINFO into filmcraft.exe on Windows (winresource, Windows-host build-dep only).
- packaging/linux/ai.storyteller.filmcraft.desktop with Icon=ai.storyteller.filmcraft.
- Web app: favicon.svg replaced by favicon.png from the same artwork; sidecars and
ATTRIBUTION.md updated.

- crates/speech (L2): Transcriber trait, FixedTranscriber, Whisper model catalogue (pinned,
SHA-256 verified) with optional downloader (feature `download`: ureq + rustls + RustCrypto),
pure-Rust Whisper inference on candle with word timestamps (feature `whisper`), log-mel, VAD
word tightening, MFCC speaker clustering. Both features off by default and for wasm.
- project: per-media-item transcripts (Project::transcripts); schema v9 with a no-op v8->v9
migration and a v8 fixture.
- edit::transcript: sequence transcript derived from clip transcripts, search, paragraphs,
word ranges, pause/filler detection, ripple delete of many ranges, caption layout.
- engine: transcript.* commands (generate, set, delete, inspect, search, select, extract, lift,
renameSpeaker, removeFillers, removePauses, createCaptions, models, downloadModel);
Session::transcriber for hosts/tests; features `whisper` / `speech-download` (also on the
desktop and CLI apps). Without whisper, transcript.generate fails with a clear error.
- ui: Text panel Transcript tab (Transcribe button, speaker paragraphs of clickable words,
Shift+click selection -> In/Out, extract/lift/remove fillers/create captions, search) with
text.transcript.* automation ids; headless UI test.
- docs/transcripts.md, crates/speech/README.md, architecture and project-files updates.
whisper-tiny measures 12.2% WER over 797 words on local samples.

- filmcraft-media: ByteReader/ReaderOpener (open containers without reading the whole
file) and the pending flag for asynchronous (web Blob) reads.
- filmcraft-codecs: MP4/MOV and Matroska open from a ByteReader; registry of reader
openers (platform sources first).
- filmcraft-engine: Services::reader / export_in_memory; streamed imports; media pool
never caches a still-loading file as offline; Session::pump_jobs advances stepped
exports on hosts without threads.
- filmcraft-export: Exporter (one batch per step, re-renders on pending reads) used by
export(); OutputSink for in-memory output.
- filmcraft-ui-egui: FrameServer::pump (time-budgeted cooperative frame jobs on wasm,
retries jobs whose media is loading); screenshots as base64 on wasm; web-time.

Decoder::stats() reports frames, tiles and the busy time of setup, tile decoding,
deblocking, CDEF, superres, loop restoration and output. The ignored perf test
measures single-threaded throughput with the thread CPU clock (robust to machine
load), prints ms/frame per stage, and the all-cores wall-clock rate next to the
load average. Adds high-quality and 4x2-tile 1080p fixtures. Decoder::with_threads
and flush() are added as the API the threaded decoder will use.

Agents' ui.* requests used ViewportCommand::Focus, so the user's typing in another app landed in FilmCraft as shortcuts (stray Extract, Mark In/Out, markers…). Verified live: the frontmost app stays frontmost through launch, ui.click, ui.key and ui.screenshot, and the requests still take effect.

Av1Decoder in filmcraft-codecs: feeds the av1C configuration OBUs before the
first sample (and after every reset), converts pictures to 8/16-bit planar
YUV with the stream's colour description, and reports random-access points
from the first frame header of each temporal unit (shown key frame) so GOP
seeking ignores bogus container sync flags. Matroska V_AV1 tracks map to an
av01 sample entry; MP4 labels show the AV1 profile.
All-intra 8-bit MP4 and 10-bit WebM files seek sample-exactly against
libdav1d. Inter frames still return "unsupported" until inter prediction
lands.

New L0 crate filmcraft-dnx, written from SMPTE ST 2019-1:2016 + Amd 1:2023
(tables extracted from the standard's text by tools/extract_tables.py).
Decoder: every compression ID (DNxHD 1235-1260 incl. field-coded and
macroblock-adaptive interlace, thin rasters, RGB 4:4:4; DNxHR 1270-1274
LB/SQ/HQ/HQX/444), 8/10/12-bit, 4:2:0/4:2:2/4:4:4, DCT and lossless alpha,
macroblock rows in parallel. Matches ffmpeg within IDCT precision (max 2 LSB,
<=50 per million beyond 1, 87-99% identical) on 22 ffmpeg fixtures; follows
ffmpeg where it departs from the standard's text (reconstruction offset,
CID 1271 weights, 4:4:4 signalling) - documented in the README.
Encoder: DNxHR LB/SQ/HQ/HQX(10/12-bit)/444, CBR at the eq. 7.1 frame sizes,
uniform-qsf binary search + per-macroblock refinement; ffmpeg decodes every
profile with -xerror (HQ luma PSNR 58.8-66.3 dB).
Wiring: MOV AVdn/AVdh import (codec label from the CID), export
Format::DnxHr (MOV AVdh, dnxProfile lb|sq|hq|hqx) in the export dialog and
file.exportMedia.

- media.createProxies: background job (jobs.list progress) transcoding with our own
encoders — ProRes 422 Proxy ¼/½, ProRes LT ½, H.264 ¼/½ (audio included) — into
<media dir>/Proxies or a chosen folder; attached when the job finishes
(Session::poll_persistence applies finished media jobs).
- media.attachProxies (duration ±1 frame and frame rate must match; size/aspect may
differ), media.detachProxies, media.reconnectFullRes, media.toggleProxies
(Preferences ▸ Media ▸ enableProxies; bumps the view revision without dirtying the
project), media.proxyPresets.
- Proxy frames are smaller; ProxySource reports the original size and the compositor
derives its pixel scale from the frame, so Motion and effects render the same
picture (44 dB PSNR vs full res with Motion + Gaussian Blur, 48 dB at ½).
Export always renders full resolution.
- ExportSettings::prores_profile (proxy / lt / standard / hq).
- project.ingestSettings + file.import: copy (fingerprint-verified), transcode,
create proxies, copy and create proxies.
- UI: Toggle Proxies button on both monitors (lit when on), Create Proxies dialog,
Project panel Proxy submenu and P badges.
- Measured (one core, 4K H.264 testsrc2): CPU composite 201 → 35 ms/frame at ¼ with
ProRes Proxy ¼, 277 → 131 ms at ½ with H.264 ¼; decode 9.2 → 0.7 ms with H.264 ¼.
- Tests: create+attach+toggle same composite modulo scale, attach checks, export
ignores proxies, ingest copy + proxies, ignored 4K benchmark, headless UI test.
