- Record Promo Video
- Autonomously capture smooth, high-FPS gameplay footage of your Phaser game — ready for TikTok, Reels, Moltbook, or X. No human input needed during recording.
- Instructions
- Record a promo video of the game at
- $ARGUMENTS
- (or the current directory if no path given).
- 1. Pre-checks
- Verify these are available:
- Dev server
- Check if one is already running (
curl -s http://localhost:3000/
). If not, start one with
npm run dev
in the background. Note the port.
Playwright
:
npx playwright --version
. If not installed:
npm install -D @playwright/test && npx playwright install chromium
FFmpeg
:
ffmpeg -version | head -1
. If not found, tell the user to install it (
brew install ffmpeg
on macOS) and stop.
2. Generate the capture script
Load the
promo-video
skill for the full technique reference.
Read the game's source files to understand:
src/scenes/GameScene.js
— find death/failure methods to patch out
src/core/EventBus.js
— event flow
src/core/Constants.js
— input keys, game dimensions
src/main.js
— verify
GAME
and
GAME_STATE
globals are exposed
Create
scripts/capture-promo.mjs
adapted for this specific game:
Patch out ALL death/failure code paths
Generate input sequences matching the game's actual controls
Include entrance animation pause (1-2s)
Default viewport:
1080 × 1920
(9:16 mobile portrait)
Default duration: 13s game-time
3. Copy the conversion script
cp
<
plugin-root
/skills/promo-video/scripts/convert-highfps.sh < project-dir
/scripts/ chmod +x < project-dir
/scripts/convert-highfps.sh 4. Run the capture mkdir -p output node scripts/capture-promo.mjs --port < port
bash scripts/convert-highfps.sh output/promo-raw.webm output/promo.mp4 0.5 5. Verify and preview Extract a thumbnail at the 5-second mark and show it to the user: ffmpeg -y -ss 5 -i output/promo.mp4 -frames:v 1 -update 1 output/promo-thumbnail.jpg Read the thumbnail image and display it. Report duration, frame rate, and file size. Tell the user: Promo video recorded! 50 FPS, mobile portrait (1080×1920).
