How it works
The resolution: "instagram-portrait" sets the canvas to 1080×1920 (9:16). Each scene plays a short clip (3-4 seconds) with fit: "cover" so the video fills the vertical frame regardless of source aspect ratio. The opening scene is shorter (3s) — short hooks retain better than long ones on social feeds.
Each step gets two stacked text elements: a big orange number anchored in the upper-left and a caption near the bottom. font-weight: "900" plus the bold sans-serif style makes the text legible against busy video backgrounds. Adjust y values to move captions if your subject lives in the lower third.
A single movie-level audio track plays underneath. volume: 0.7 keeps the music present but not overwhelming; combine with the automatic subtitles pattern if you want spoken voiceover layered on top.
Try it
Replace the 4 src video URLs with your own clips. For a different format (TikTok, Reels), the resolution stays the same (instagram-portrait). For YouTube Shorts use the same — it's the standard 9:16.
