Summary

  • Square by default. The picture-in-picture camera now starts square. The wide shape added nothing and took too much room.
  • "Rectangle" becomes "Original". It always followed the camera's own aspect (a portrait camera stays portrait); the label now says so. Renamed in the 15 app locales and on the 8 website locales.
  • Roundness default per shape: 70% for Square, 40% for Original. An untouched roundness follows the shape when it changes; a tuned one is kept. The slider's reset goes to the active shape's default.
  • Existing projects keep their look: a stored shape still reads with the rounding it drew. Only a project with no stored shape gets the new factory default.
  • Editor drag box fix: it was laid out from a fixed 4:3 camera while the native canvas drew the real one. Preview and scene now share webcamBoxSourceSize, so the box matches the picture (a portrait camera in Original gets a portrait box).

Test plan

  • tsc --noEmit (app + tests), Biome, i18n:check
  • Targeted Vitest: 1743 tests, incl. a new one on the roundness following the shape
  • Visual check in the app (Etienne)

Summary by CodeRabbit

  • New Features
    • Choose Square or Original for the picture-in-picture camera. Original preserves the camera’s proportions, including portrait orientation.
    • Square is now the default camera shape. Default corner rounding adjusts to the selected shape, while custom rounding is preserved.
    • Camera framing now reflects detected camera dimensions.
  • Documentation
    • Updated camera-shape guidance and defaults in supported languages.

… own proportions

The picture-in-picture camera now starts square. The other shape, which follows the
camera's own aspect (a portrait camera stays portrait), is labelled "Original" instead
of "Rectangle".

Each shape has its own default roundness, 70% for Square and 40% for Original. An
untouched roundness follows the shape when it changes; a tuned one is kept. Projects
saved with a shape keep the look they had.

The editor's drag box was laid out from a fixed 4:3 camera while the native canvas drew
the real one. Both now read webcamBoxSourceSize, so the box matches the picture.

Walkthrough

Webcam layout sizing now uses camera dimensions from the webcam-size cache when available. Webcam shape defaults to square, while Original preserves camera proportions. Roundness defaults and shape labels are updated in settings, translations, and documentation.

Changes

Native camera sizing

Layer / File(s) Summary
Calculate and apply camera source dimensions
src/native/sceneDescription.ts, src/components/ai-edition/PreviewCanvas.tsx, src/native/sceneDescription.test.ts
webcamBoxSourceSize applies crop settings to camera or probed dimensions, with a 960×720 fallback. PreviewCanvas subscribes to webcam-size cache revisions and uses the calculated size in composite layout. Geometry test fixtures now set the rectangle shape explicitly.

Webcam shape options

Layer / File(s) Summary
Define shape defaults and resolve stored settings
src/lib/projectDefaults.ts, src/lib/compositeLayout.ts, src/components/video-editor/types.ts, src/components/video-editor/projectPersistence.test.ts, src/lib/ai-edition/store/editorSettings.test.ts
Square becomes the default webcam mask, with roundness defaults of 0.7 for square and 0.4 for rectangle. Stored legacy shapes and roundness values are resolved, and finite stored roundness is clamped to [0, 1].
Update shape controls and labels
src/components/ai-edition/RightPanes.tsx, src/components/ai-edition/RightPanes.layout.test.tsx, src/components/ai-edition/RightPanes.tooltips.test.tsx, src/i18n/locales/*/settings.json, website/docs/*, website/i18n/*/docusaurus-plugin-content-docs/current/*
Settings labels the rectangle-proportion option “Original.” Shape changes update roundness to the new shape default when the existing value matched the prior default; otherwise, they preserve the custom value. Tests, translations, and documentation reflect the options and defaults.
