- filmcraft_edit::frame_size::scale_motion: Sequence Settings' "Scale motion effects
proportionally when changing frame size". Every video clip's Motion Position maps through
p' = c1 + k(p - c0) and Scale / Scale Width multiply by k = min(W1/W0, H1/H0), static values
and keyframes: a plain proportional scale for the same aspect, and on an aspect change the old
frame fits inside the new one, centred. Automatic positions stay automatic, Scale to Frame
Size clips keep their Scale (the renderer refits them), Anchor Point and Rotation stay.
- sequence.settings: new dropFrame, maxRenderQuality, workingSpace, wideGamut, autoToneMap and
scaleMotion (default false, so existing callers are unchanged) params, in the same undo step;
returns {"scaledClips": n}. Drop-frame on a rate without it is refused atomically.

- 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.
