CapRust 0.9.0 — chroma key, multicam, screen recording

Chroma key, multi-camera groups, and screen recording. First minor
bump since the beta line.

Install

Windows 10 / 11, 64-bit.

1. Download CapRust-0.9.0-win64-setup.exe below.
2. Run the wizard. Per-user install by default (no UAC prompt);
   pick "Install for all users" if you prefer Program Files.
3. Launch from the Start Menu.

On first run CapRust offers to download a static FFmpeg build
(~110 MB) if ffmpeg / ffprobe are not on your PATH.

Highlights

• Chroma key (green screen) - per-clip key color, similarity,
  and edge blend. Preview and export go through the same
  filtergraph stage, so the keying you see is what you ship.
• Multi-camera groups - right-click 2+ selected clips to create
  a group. Switch angle from the Multicam dock panel; preview and
  export follow. Sync angles button correlates the audio
  envelopes and writes per-angle offsets.
• Screen recording - File -> Record screen. Native DXGI
  Desktop Duplication, H.264 mp4, cursor overlay (color +
  monochrome), monitor picker, duration, fps. Recordings land in
  %APPDATA%\CapRust\recordings\ and auto-import into the
  media bin.
• Silent-video export fix - clips whose source has no audio
  stream no longer break preview and export.

See CHANGELOG.md
for the full list.

Requirements

• Windows 10 1809 or later (x64)
• ~150 MB free disk space, plus ~110 MB for FFmpeg and more for
  AI models if you want auto-captions or narration.

Known issues

• Binary size is ~24 MB (target was 20). Size optimization is a
  post-beta pass.
• Auto-update check is manual (no silent background updater yet).
• Without code signing, Windows SmartScreen may show a warning;
  click "More info" then "Run anyway".
