FilmCraft is a non-linear editor for people who know Premiere: the same panels, workspaces, tools and shortcuts, so your hands already know where everything is. Underneath, it is new from the bitstream up. The H.264, HEVC, ProRes and AAC codecs are our own, written in Rust from the public specifications. A GPU compositor works in linear light. Frame math runs on exact integer time, so edits never drift. And every action in the app is a command that an AI agent can drive as precisely as you can.

_{The Assembly workspace, cutting a trailer for Night of the Living Dead (1968) with an insert from Carnival of Souls (1962).}

A timeline you already know. Source and Program monitors, bins with thumbnails, a multi-track timeline with patch and target buttons, sync locks and linked selection. The Editing, Assembly, Color, Effects and Audio workspaces are all there, and every panel docks wherever you want it.

• Three-point editing. Mark In and Out in the Source monitor, then insert (,) or overwrite (.) onto the patched tracks. Lift (;) and extract (') take ranges back out.
• Every trim. Ripple, roll, slip, slide, rate stretch and razor tools. Trim mode selects edit points as ripple, roll or trim, nudges them a frame at a time (⌥← ⌥→, ×5 with ⇧), toggles the trim type with ⌃T and extends them to the playhead with E. Q and W ripple-trim to the playhead. The Trim Monitor shows both sides of the edit, and dynamic trimming trims live while it plays: L forward, J back, K to stop and commit as one undo step.
• Exact time. Every edit is computed on integer ticks: 254,016,000,000 per second, which divides evenly by every common frame rate and sample rate. 23.976, 29.97 drop-frame and 59.94 are exact, not approximate.
• The details pros rely on. Markers with colours, names and durations; add edit (⌘K) on one or all tracks; nesting; copy, paste and paste insert; ripple delete and close gap; snapping; unlimited undo with a History panel.
• Your keys. A Keyboard Shortcuts editor (⌥⌘K) with a drawn keyboard, panel-specific shortcuts, conflict warnings and presets for FilmCraft, Premiere Pro, Final Cut Pro and Avid key layouts.
• Never lose work. Saves are atomic, auto-save keeps a rolling set of versions, and a crash-recovery journal written about a second after each edit brings back unsaved changes after a crash or power cut.

A complete Lumetri-style grading panel, in the order a colourist works:

• Basic Correction: temperature and tint, exposure, contrast, highlights, shadows, whites, blacks, saturation.
• Creative: eight built-in looks with an intensity control, plus faded film, sharpen and vibrance. The looks are colour transforms written in code, not LUT files.
• Curves: an RGB curve editor with monotone-cubic interpolation (no overshoot), and hue vs saturation, hue vs hue, hue vs luma, luma vs saturation and saturation vs saturation.
• Color Wheels: shadow, midtone and highlight wheels, each with its own lightness control.
• HSL Secondary: key a colour by hue, saturation and luma, view the key as a matte, and correct only what you selected.
• Vignette: amount, midpoint, roundness and feather.

The Lumetri Color panel. Basic Correction, Color Wheels and every other section, each with its own on/off switch.

Scopes that tell the truth. The waveform and vectorscope are computed from the graded frame. All grading happens in linear light, in 32-bit float.

_{NASA's Earth Views from the ISS with a look applied, and the Effects browser open on the dissolves.}

• Premiere 26's full Video Effects bin (93 effects in 16 folders), the Legacy bin and the obsolete effects old projects use, plus around 30 transitions. Blurs (Bokeh, Focus, Compound), keys (Ultra Key, Track Matte), distortions (Corner Pin, Turbulent Displace, Warp Stabilizer), Lights & Glows, Immersive Video (VR) effects on equirectangular footage, Posterize Time, Echo and more. Cross dissolve, dip to black or white, film dissolve, wipes, irises, pushes, slides, zooms, page peel, cube spin and more.
• Motion and opacity on every clip: position, scale, rotation, anchor point and anti-flicker, plus 26 blend modes.
• Keyframes like Premiere's: linear, Bezier, auto and continuous Bezier, hold, ease in and ease out. Effect Controls shows a keyframe lane for every parameter, and each animated parameter opens into value and velocity graphs with draggable influence handles.
• A GPU compositor built on wgpu (Metal, Vulkan, DirectX 12, WebGPU). It samples YUV straight from the decoder with footprint supersampling and blends in linear light. A CPU path renders the same frames, and the two are tested against each other.

_{An eased push-in on the title card: the value graph, the velocity graph and the Bezier influence handle.}

• Loudness meters to broadcast standards. Momentary, short-term and integrated loudness and true peak to ITU-R BS.1770 and EBU R128, alongside the peak meters. Our integrated reading matches ffmpeg's ebur128 filter to the tenth of a LU.
• Clip effects on our own DSP library: parametric EQ, high-pass, low-pass and band-pass filters, dynamics, a true-peak limiter, delay, reverb, DeNoise, DeHummer, invert and pitch shift. Parameters can be keyframed. Effects stay continuous across scrubbing, playback and export, with latency compensated.
• Audio Track Mixer and Audio Clip Mixer: faders, pan, mute, solo, five insert slots per track (pre- or post-fader), sends, submixes and a Mix track, all sample-accurate and latency-compensated. 24 tracks with three effects each mix about six times faster than real time on one core.
• Automation like a console: Read, Latch, Touch and Write modes recorded live from the mixer during playback, shown and edited as track keyframes on the timeline. Plus the Audio Gain dialog (set, adjust, normalize) and constant-power crossfades.
• Audio-clock playback. The sound card is the master clock, so picture follows sound and never the other way round.

• A real text engine: OpenType shaping with kerning and ligatures, bidirectional text, line breaking, tracking and leading, drawn in linear light and sharp at any scale or rotation.
• Type, Shape and Pen tools on the Program monitor: click to type, edit with a caret and selection, drag out rectangles, ellipses and paths. Graphic clips hold text and shape layers with fill, strokes, background and shadow, all keyframable, and edited in the Properties panel.
• Captions: caption tracks in Subtitle, CEA-608, CEA-708 and Teletext formats; import and export SRT, WebVTT and SCC with frame-exact timing; edit captions in the Text panel and burn them into exports.

No FFmpeg inside. The video codecs, AAC, Opus and the containers are our own Rust code, implemented from the public ITU-T, ISO and IETF specifications and tested frame by frame against ffmpeg as an external oracle.

MXF and hardware decode are next (roadmap).

_{Export mode, set to write the trailer as H.264 MP4.}

• H.264 MP4 with AAC, using our own encoders. A 6-second 960×540 render takes 1.3 seconds and decodes cleanly in ffmpeg with error concealment switched off.
• Also: Apple ProRes 422 HQ and Motion JPEG in QuickTime, MXF OP1a and Avid-style OP-Atom (DNxHR, ProRes or H.264 with PCM and start timecode), PNG sequences, animated GIF and WAV.
• Background jobs with progress and cancel, so you keep editing while it renders.
• Render previews: the render bar marks segments green, yellow or red; rendered previews are cached by content, so an edit only invalidates what it touches and undo brings the green back.

Move timelines between FilmCraft and every other editor:

• Final Cut Pro 7 XML (xmeml): the format Premiere and DaVinci Resolve exchange. It carries nested sequences, transitions, generators, Motion, Opacity, Time Remap and audio levels, with keyframes.
• FCPXML 1.9–1.11: the spine, connected clips as lanes, transitions, retiming and compound clips.
• OpenTimelineIO: the open interchange format of the film industry, round-tripping every FilmCraft detail through metadata.filmcraft.
• CMX 3600 EDL: the oldest format still in use, with drop-frame timecode, dissolves, wipes, speed changes (M2) and one EDL per track.
• AAF (Edit Protocol): for Avid Media Composer and Pro Tools. Video and audio tracks, dissolves and dips, clip volume with keyframes, markers and source timecode; audio embedded or as separate WAV / AIFF files, trimmed with handles, with clip effects rendered in and broken out to mono, plus an optional video mixdown. Import reads AAF back, extracting embedded audio.
• OMF 2.0: the audio-post handoff: the audio tracks with crossfades and gain, sample-accurate, with the audio encapsulated or alongside.

Import merges the document's bins, media and sequences into your project as one undoable step, and links each media file it finds on disk.

Every menu item, button, slider and drag in FilmCraft is a command with an id, typed parameters and an enabled state. There are about 135 engine commands so far, with the rest of Premiere's catalogue on the way. The UI, the CLI, a JSON control channel and an MCP server all dispatch the same commands, so Claude or any agent can cut, trim, grade, mix and export exactly the way a person does. The UI can also be driven at the level of mouse and keyboard: every widget has an automation id, and agents can click, drag, type and take screenshots.

// over the control channel (JSON lines on TCP) or as MCP tool calls
{"method": "engine.execute", "params": {"command": "timeline.place",
  "params": {"item": 1, "track": "V1", "seconds": 0, "sourceIn": 284298240000000, "duration": 1270080000000}}}

The trailer and the grades in these screenshots were built exactly this way, by an agent driving the running app.

• Native on macOS, Windows and Linux, with a native macOS menu bar.
• The web: every crate up to the engine compiles to wasm32; the browser front end is next.
• Swappable UI. The interface is one crate (ui-egui) over the engine, so a different front end can replace it without touching editing logic.

cargo run --release -p filmcraft                           # the desktop app, with a demo project
cargo run --release -p filmcraft -- --control 9876         # plus the JSON-lines control server
cargo run --release -p filmcraft-cli -- commands           # list every engine command
cargo run --release -p filmcraft-cli -- mcp                # MCP server (headless)

FilmCraft is young and moving fast: roughly 45% of the way to Premiere Pro parity, with editing, trimming, colour, keyframes, titles, captions, mixing, codecs and export working today. ROADMAP.md tracks every milestone with estimates.

A layered Cargo workspace:

Nothing below the front ends depends on a UI toolkit or OS API. cargo xtask ci checks formatting, lints, tests, the layering rules, asset attribution and the wasm build.
