Does product video hurt Core Web Vitals (LCP)?

Only if poorly integrated. A video that loads immediately and blocks LCP is a problem. Best practices: lazy-load the video (load only on scroll-to), use a JPEG or WebP poster image as placeholder, never autoplay with sound. Seegea ensures these rules are followed during media publication.

What is the ideal product video duration?

15 to 60 seconds for a product demo. Under 15 seconds: too short to show value. Over 90 seconds: drop-off rate climbs above 70%. 30 seconds is the sweet spot on mobile e-commerce, where 70% of views happen.

Does Google Shopping accept product videos?

Yes, since 2022. Google Shopping supports videos in product listings (via the video_link attribute in the XML feed). The video must be hosted on YouTube. It is displayed in product detail pages and can boost click-through rate by 15 to 25%.

How do I add a product video in Shopify without slowing the page?

Add the video in the Shopify product media gallery (Admin → Products → Media → Add video). Shopify transcodes and serves it via CDN automatically. For weight optimization, compress to a maximum of 50 MB before upload. Seegea manages video metadata (title, alt, position) from the catalog grid.

E-commerce product video: formats, weight and Shopify integration

Adding product videos to your Shopify store is a two-step process: technical integration (format, weight, hosting) and performance optimization (LCP impact, autoplay policy, mobile behavior). Getting both right simultaneously is what separates a video that converts from one that just slows the page.

Compatible platforms

Technical specs for product videos

Format and codec

MP4 with H.264 video codec and AAC audio. This combination works on all browsers and devices without polyfill. WebM is a valid alternative with slightly better compression but lower compatibility (no Safari on iOS 15 and below).

Resolution and weight

1080p (1920×1080) at 2 to 5 Mbps for a 30-second video. Target: under 30 MB for product demos. Compress with HandBrake (free) or FFmpeg before upload. Shopify re-encodes internally but starting from a clean source is better.

Autoplay rules

Chrome and Safari allow silent autoplay (muted). Autoplay with sound is blocked by default on all browsers. Always use a WebP or JPEG poster image to show on load — it prevents the blank video frame that hurts LCP.

Criterion	Without optimization	With Seegea + best practices
Video weight	200+ MB raw	20-50 MB (H.264, 1080p)
LCP impact	High (video blocks render)	Negligible (lazy-load + poster)
Mobile experience	Autoplay with sound (blocked)	Silent autoplay or click-to-play
Google Shopping	Not submitted	YouTube video_link in feed
Alt text / metadata	Empty	AI-generated from product attrs

Autoplay video with sound is blocked by Chrome, Safari, Firefox and Edge by default. If your theme enables autoplay with sound, it will silently fail for 95% of visitors while still loading the video file — maximum weight penalty, zero conversion benefit.

How Seegea handles product video metadata

Seegea does not compress or host videos directly — Shopify handles that via its CDN. What Seegea manages is the product media metadata at catalog scale:

Video position in the media gallery (main vs supplementary)
Video alt text for accessibility and SEO
Poster image selection — Seegea selects or generates the best frame as a WebP thumbnail
Bulk video linking — associate a YouTube URL to hundreds of products by column

Built in France between Annecy and Chantilly, Seegea manages all your product media — images and video metadata — from a single tabular interface, with immediate push to Shopify or PrestaShop.
