# FilmCraft Roadmap

Progress toward parity with Adobe Premiere Pro, with estimates. Updated as milestones land.

**Last updated:** 2026-10-05 · **Feature checklist:** ~87% · **Ready for real work:** ~50–60% · **Code:** 35 crates, 1605+ tests

Two numbers, because they answer different questions. The **feature checklist** counts whether
Premiere's menu items, effects, panels and formats exist in FilmCraft. **Ready for real work** is
our honest estimate of how close FilmCraft is to replacing Premiere for an editor on real
projects: depth, correctness, robustness, speed and the pro ecosystem. The gap between the two
is the work that matters most now. Agents: read [Where we are lacking](#where-we-are-lacking)
before choosing work.

## Honest assessment (2026-10-05)

### How the checklist number is made, and what it doesn't tell you

- **Partly measured.** The menu figure comes from diffing a dump of Premiere 26.5's menus against
  `filmcraft-cli commands`. The effects, transitions and audio-effects counts are checked by unit
  tests against Premiere's Effects panel tree (`premiere_26_video_effects_catalogue`,
  `premiere_audio_set_is_complete_and_foldered`, `premiere_26_transition_tree`).
- **Partly agent-reported.** The other areas' percentages are written by the agents doing the work.
  No automated parity check runs in CI (PhotoCraft has `cargo xtask parity`; we don't yet), so
  nothing stops a number drifting upward.
- **Presence, not quality.** An item counts once it exists. An effect described as an
  "approximation" counts the same as an exact one. Nothing compares our rendering with
  Premiere's.
- **Weights understate what users hit first.** Performance carries 5%. Plugins and AI features
  aren't in the scorecard at all.

### By dimension

| Dimension | Checklist says | Honest estimate | Evidence |
|---|---|---|---|
| **Feature breadth** (menus, commands, panels) | ~86–95% | **~85%** | Menu diff against Premiere 26.5; effect, transition and audio-effect catalogues complete by test. The long tail is mostly there. |
| **Correctness in depth** | not tracked | **~60–70%** | A first-time contributor found four real bugs in core paths within hours (#5–#8: AIFF import failed, Slide left linked audio behind, transitions didn't follow ripple trims, export ignored start/end times). User reports: Color Matte always grey with no picker (#29); ALSA audio error on Linux (#23). Settings are "most wired", not all. |
| **Codecs and media** | ~90% | **~75%** | Our decoders are bit-exact on conformance streams. Real camera and phone media (variable frame rate, damaged files, unusual containers) is far less tested. No camera RAW (RED, BRAW, ARRIRAW), no E-AC-3. |
| **Export** | ~92% | **~70%** | Delivery: H.264 only (ProRes, DNxHR and image sequences cover mastering). No HEVC or AV1 export. AAF and OMF have never been validated in Avid Media Composer or Pro Tools. Export renders and encodes on the CPU only. |
| **Performance and hardware** | ~62% | **~35–40%** | Premiere runs effects, decoding and encoding on the GPU and the hardware media engines. Here, hardware decode works on macOS only (VideoToolbox, #33; active in the desktop app only since #41, so releases up to 0.2.1 decoded in software). The GPU does compositing, blend modes (#32) and 31 common effects (GPU2): colour adjustments, crop/flip/transform, blurs, sharpen. Lumetri, keys, masks, the remaining effects, export and encoding are CPU. Linux and Windows have no hardware path. 8K and AV1 aren't real-time. The effect list shows Premiere's "GPU accelerated" badge, but only 31 effect ids run on the GPU here; the rest, Lumetri included, run on the CPU. |
| **Stability** | not tracked | **improving, unproven** | The never-crash pass (no panics in product code, last-resort guards) landed on 2026-10-04. There's no field record from real users' projects yet. |
| **Plugins and pro ecosystem** | not tracked | **~0–10%** | No audio plugin hosting (VST3 / Audio Units) and no third-party video effects (OpenFX). For many professional editors this alone rules FilmCraft out. Team Projects and Productions are out of scope by design. |
| **AI features** | partial | **~25–35%** | Speech to text exists but is off in default builds (the `whisper` feature). Enhance Speech is a DSP chain, not a model. Auto Reframe is approximate. No Generative Extend, and no media-intelligence search or auto colour. |
| **Platforms** | not tracked | **macOS solid; Windows and Linux thin** | Development and testing happen on macOS. Windows and Linux are built for releases but barely exercised at runtime. The web build is a compile target; the browser app shell isn't finished. |
| **UI fidelity** | ~85% | **~80%** | Agents compare with Premiere reference screenshots; this hasn't been checked independently. |

### Where we are lacking

In priority order. Agents should prefer this work over adding more checklist items.

1. **Hardware acceleration** (#30), the most visible gap to users:
   - hardware decode on Linux (VA-API) and Windows (Media Foundation);
   - zero-copy decoded frames into wgpu;
   - the remaining effects on the GPU: Lumetri, keys, Vignette, Video Limiter, masks (31 common effects are done);
   - GPU export, then hardware encode (H.264 / HEVC).
2. **A measured parity number.** Add `cargo xtask parity`, run in CI. It should cover menus,
   commands, effects, transitions, panels, preferences and formats against the Premiere snapshot in
   `plan/premiere/`. It should report presence and fidelity separately (exact, approximate, stub).
3. **Real-world media corpus.** Phone, camera and screen recordings, variable frame rate, damaged
   files, long GOPs, odd containers. Each gets an import → edit → export round-trip test with an
   ffprobe / ffmpeg oracle.
4. **Workflow acceptance tests.** Scripted MCP sessions that do real jobs end to end: assemble and
   trim a scene, colour it, mix and loudness-normalise it, caption it, deliver it, round-trip
   through XML / AAF.
5. **Windows and Linux at runtime.** CI that runs the test suite and a headless playback/export
   smoke test on both, not just release builds. Fix the Linux audio path (#23).
6. **Delivery codecs.** HEVC and AV1 export: hardware encoders first, and `rav1e` (BSD-2) for AV1.
7. **Plugin hosting** (VST3 / Audio Units, then OpenFX). Needs FFI, so it falls under the isolated
   `unsafe` crate rule (AGENTS.md §0.3). **Owner decision needed** before starting.
8. **AI features** with openly licensed local models: transcription on by default, text-based
   editing, speech enhancement, reframing.
9. **The web app shell**: file access, WebCodecs, audio.

### Where we're going

**Next:** close items 1–5. Hardware acceleration fixes the gap users notice first (CPU-bound 4K playback and export). The
parity tool, media corpus and workflow tests make the progress number trustworthy. Windows and
Linux CI makes "runs everywhere" true.

**After that:** delivery codecs, plugin hosting (pending the owner's decision) and AI features,
measured with the same tools.

**Goal:** "ready for real work" at 85%+, measured rather than estimated, on all three desktop
platforms.

| **Weighted total** | | | **~87%** |

## Estimate to parity

This estimate is for the **feature checklist**. Closing the honest-assessment gaps (above) is the
"Robust on real-world material" row, plus plugins and AI features, which it doesn't include.

Measured throughput in the last work block (2026-10-01 night → 10-02): five Opus 5.5 agents in
parallel for ~4.5 wall-clock hours (~18 agent-hours including integration) moved parity by ~4 points
(≈4–5 agent-hours per point), on a machine that was heavily overloaded (load 150–300 on 14 cores) and
once ran out of disk. The remaining points are a long tail (each effect, dialog and preference page is
small, but there are many), so the estimate applies a 1.3–1.5× tail factor.

| | Opus 5.5 agent-hours | Wall-clock (4–5 parallel agents + integrator) |
|---|---|---|
| Feature parity by checklist (~19 points left) | ~90–125 | **~20–32 h** |
| Robust on real-world material (codec edge cases, 4K/8K performance, pro workflows) | +120–200 | **+30–50 h** |
| **Total to "100% and better"** | **~210–325** | **~50–82 h (≈2–3.5 days, 24/7)** |

The 2026-10-02 block moved parity ~62% → ~72% with six agents in ~6 wall-clock hours, despite the
disk filling twice; the remaining work is mostly panels (scopes, Metadata, Media Browser), export
presets/queue, codecs (MXF, image sequences, hardware decode), performance and graphics templates.

Limits on speed: CPU and disk on one machine (more than ~5 agents slows everyone down: each worktree
build is 6–7 GB and a full `cargo xtask ci` takes 20–60 min under load), and a single integrator
merging, resolving conflicts (e.g. two agents bumping the project schema) and re-running CI. With one
agent and no parallelism, multiply wall-clock by ~3–4.

Not reachable clean-room and locally: **Generative Extend** (needs a large video-generation model).
**Enhance Speech** and **Auto Reframe** are feasible only with openly licensed models we can ship.

## Running now

- **Hardware acceleration (#30):** landed: blend modes on the GPU (#32); VideoToolbox hardware decode + the `platform` FFI crate (#33); 31 common effects on the GPU (GPU2). Next: VA-API (Linux) and Media Foundation (Windows) decode, zero-copy upload, Lumetri on the GPU.
- **Next:** [Where we are lacking](#where-we-are-lacking) items 1–5. GPU export waits for the export-crate work (#19 and the never-crash follow-up) to land.

## Log

- **2026-10-06:** 21 community PRs landed (#19, #28, #38, #39, #41–#60). Highlights: hardware decoding is now actually on in the desktop app (#41: `register()` sat inside a `log::info!` that never ran, so #33's VideoToolbox path only worked in the CLI and benchmarks); decode memory on long timelines cut sharply (frame pool, shared GOP-cache budget, positional file reads); exports are byte-identical across machines (#19); crash fix for odd track names over MCP (#44); ripple trim, ripple delete and speed changes move split-edit clips once (#56–#58); Japanese interface using an installed system font (#38; no fonts bundled); MCP annotations, resources, export progress and cancellation (#28).

- **2026-10-05:** honest assessment added (checklist ~87% vs ready for real work ~50–60%). Hardware acceleration started (#30): blend modes on the GPU (#32); VideoToolbox decode + `platform` crate, the one crate allowed `unsafe` (#33). Community fixes landed: AIFF import, export start/end ranges, transitions following ripple trims, Slide moving linked audio (#5–#8).

- **2026-10-04 (later):** interchange + MXF export (M11.4/M6.6): own compound-file container (`crates/cfb`), AAF Edit Protocol import/export (embedded/linked/consolidated audio, video mixdown, handles, breakout to mono), OMF 2.0 export (Bento), MXF OP1a/OP-Atom writer (DNxHR/ProRes/H.264/PCM) as export formats. 1605 tests.

- **2026-10-04:** MPEG-2 (M9.15): own MPEG-2/MPEG-1 video decoder (4:2:2, interlaced, field pictures; IEEE 1180 IDCT), MPEG TS/PS demux (AVCHD .mts, .m2ts, .ts, .mpg/.vob/.mod), own AC-3 decoder (ATSC A/52), MP2, LATM AAC, Blu-ray/DVD LPCM, MPEG-2 in MXF/MOV/MP4/MKV. 1562 tests.

- **2026-10-03 (evening):** Project panel and Media Browser (M12.7): Freeform view (stacks, arrangements), Icon view hover scrub with In/Out, list columns from all metadata, ten view presets, multiple Project panels; Media Browser with Favorites/drives/recent, back/forward, filters, thumbnails, Edit Columns, ingest, drag to timeline; all as `project.*` / `mediaBrowser.*` commands. 1513 tests.

- **2026-10-03 (later):** graphics & captions (M10.7): `.fcgt` graphics templates (export/install/apply/edit, 8 original built-ins; Adobe .mogrt refused), Essential Graphics Browse/Edit, rolls/crawls, responsive design pins and time, per-character styles, Upgrade Caption to Graphic / to Source Graphic, MCC/EBU STL/TTML/DFXP, Replace Fonts; schema v12. 1479 tests.
- **2026-10-03:** 4K H.264 playback (M4.9): vectorised deblocking, branch-free CABAC bins and column-parallel inverse transforms cut H.264 decoding by 23 % (cycles per frame, bit-exact; 4K cold seeks −27 % CPU); opt-in draft decoding (Settings ▸ Playback) skips deblocking of non-reference pictures and uploads decimated planes while playing at 1/2–1/4, never for paused frames or exports; conformance runs 1, 3 and all threads. 4K plays 192/0 at load 100–140 (before: only at load ~90).
- **2026-10-03:** 4K VP9 / HEVC / AV1 playback (M4.10): VP9 frame threading (references published per superblock row, loop filter overlapping the next frames) plus a vectorised loop filter, column-parallel transforms and 16-bit MC cut VP9 work by 25 % single-threaded and 44 % with all cores (4K decode 8 → 27–34 fps at load ~200); HEVC −28 % (vectorised SAO, MC without per-block zeroing, batched bypass bins), AV1 −20 % (fixed-width MC, recycled planes); opt-in draft decoding for all three; bit-exact at 1, 3 and all threads. 4K VP9 and HEVC now play 192/0 at load ~200 (before: 0–58 of 192 shown).

- **2026-10-03:** keyboard parity (M3.12: 143 new commands on Premiere's default keys, table validated against the registry), audio (M7.8: 5.1 tracks/submixes/Mix, 5.1 panner, BS.775 downmix, 5.1 WAV/MOV/AAC export, voice-over record with punch-in, Remix, Clip Mixer Latch/Touch/Write). 1432 tests.

### Interface localization

Edit > Language switches English/Japanese and persists in UI state. Commands `app.language.english` and `app.language.japanese` are reachable through the control channel. Core native/in-window menu labels are translated; untranslated labels use English. Japanese text uses the Japanese fonts from [craft-fonts](https://github.com/storytold/craft-fonts) when FilmCraft is built with them (`CRAFT_FONTS_DIR`; all official releases, including the web build), otherwise a Japanese font already installed on the system; with neither, switching to Japanese is refused with a message. Dialog/panel translation coverage remains open. Existing vertical text support is preserved.
