Add it

Customize → Add section → search “Video carousel”. The internal section file is named story-videos.liquid.

Per-video block

• Upload video (Shopify-hosted) — the recommended path. Direct .mp4 upload; the poster image is auto-generated from the first frame.
• External video URL — fallback: a direct .mp4 link from Shopify Files or a CDN.
• Poster image (optional) — override the auto thumbnail. Leave empty to use the video first frame.
• Title / caption — displayed in the lightbox overlay.
• Linked product — attaches a “Shop” card inside the lightbox pointing to that product.
• CTA label — button text (“Shop this product” default).

Section settings

• Eyebrow + Heading + Subheading.
• Heading size — H1 / H2 / H3.
• Tile aspect ratio — 9:16 portrait (Instagram reel) / 3:4 / 1:1 / 4:5.
• Show navigation arrows — prev/next on desktop.
• Show pagination dots.
• Show caption on card — displays the video title under the tile.
• Autoplay video when lightbox opens — muted autoplay (browser policy).
• Loop video in lightbox.

The lightbox

Clicking a tile opens a fullscreen modal:

• Video auto-plays muted. The mute / unmute toggle is at bottom-right.
• Close X at top-right.
• Vertical progress bars on the left show position in the playlist. Click any bar to jump.
• Arrow keys / on-screen prev-next / swipe up-down to navigate between videos.
• The “Shop” card (if a product is linked) sits at the bottom with image + price + CTA.
• Escape closes the lightbox.

Tips

• Keep each video under 15 seconds for max engagement.
• 9:16 vertical is the most editorial format — record in portrait mode.
• Repurpose existing Instagram Reels here — they’re already the right format.
