How to set up video reviews

The Video reviews block shows a row of customer review videos on the product page. Tapping one opens a full-screen vertical reel with the current product pinned as an add-to-cart card.

Each product reads its own videos from a metafield, so every product can show a different set.

Video walkthrough: add video reviews to product pages with Helix.

Step 1 — Create the metafield

In Shopify admin, go to Settings → Metafields and metaobjects → Products and click Add definition, then set:

• Name — Video reviews

• Namespace and key — modutheme.video_reviews

• Type — Video (File), list of values

Click Save.

Creating the video_reviews metafield definition in Shopify admin

The namespace and key must be exactly modutheme.video_reviews. Helix reads this fixed key — any other name is ignored.

Step 2 — Upload review videos to a product

1. Open a product in Shopify admin.

2. Scroll to Metafields → Video reviews.

3. Add one or more video files (upload new ones or pick from Content → Files).

4. Save the product.

Repeat for every product that should show review videos. Videos appear in the order you add them.

Step 3 — Add the block to the product page

In the theme editor, open a product template → Product information section → Details block → Add block → Video reviews, then save.

Adding the Video reviews block to the product Details block

Only MP4 videos are supported. A product with an empty Video reviews metafield shows no feed — the block stays hidden for that product.

Alternative: the standalone Video reviews section

To show the same reel on a page that isn't tied to a single product, add the Video reviews section instead and upload videos directly into its child blocks in the theme editor — no metafield required.
