tools/films is a Remotion project that renders the 30-second film "Export before 16 October", the third part of the launch campaign. It tells people who use the Microsoft Whiteboard app with a personal account to export each board before the app retires on 16 October 2026, and shows SQLBI Whiteboard opening the exported ZIP. Like tools/AssetGenerator, it sits outside Whiteboard.sln.

Remotion is used under its free license, because SQLBI has fewer than four employees. The README records this with the license URL.

Rendering

cd tools\films
npm install
npm run studio       # preview
npm run stills       # review stills of every shape, into out\stills
npm run render:all   # every rendition and the poster, into out

There is one script per rendition: render:16x9, render:1x1, render:4x5, render:9x16, and render:poster. Each shape renders at twice its size into out\master (3840 × 2160 for 16:9), and ffmpeg scales it down to the rendition. Rendering runs on Windows, because the type is Segoe UI Variable Display from the installed fonts. Remotion's own Chrome Headless Shell finds the real font; out\stills\font-check.png measures it against Segoe UI Variable Text, Segoe UI, and a monospace fallback.

The four shapes come from one composition. A landscape frame puts the text in a navy panel on the left, as the social card does. A square or portrait frame puts the window at the top and the text in a navy panel below it.

Captures, voice, and music

• Captures go in tools\films\captures\ under the names in the README's shot list (C1 to C4). Until a file is there, the film shows a navy placeholder with the capture's name and what it will show. src/film1/captures.ts sets where the film starts reading each capture, its speed, and where the numbered callouts sit. The callout positions are estimates for a 2560 × 1440 capture at 150 % scaling, so they need checking against the real captures.
• The voice goes in tools\films\audio\film1-vo.mp3. audio/film1-vo.txt holds the script to paste into ElevenLabs and the phrase each beat covers. Until the file exists the film carries a silent track of the same length.
• Beat start times are in src/film1/beats.json, so aligning the film to the voice is an edit of that file. The README gives the ffmpeg command that lists the pauses between phrases.
• The music bed goes in tools\films\audio\film1-bed.mp3. It plays 22 dB below the voice and fades out under the end card. No music was present, so these renders have none.

Captures, audio files, node_modules, and everything under out are gitignored.

Renditions

These were rendered with the placeholders and the silent track, so the files will grow once real captures are in.

Each video is H.264 High, yuv420p (limited range), 30 fps, 900 frames, with an AAC track at 128 kbps and the index at the start of the file. ffprobe reports 30.000 s for the file, the video, and the audio, and the audio starts at 0 s. The review stills at 2, 6, 10, 14, 20, 25, and 29 s were checked for every shape: text inside the safe area, nothing clipped, and the font is Segoe UI Variable Display.
