> Quick answer: Film vertically in 9:16 at 1080x1920px, keep it under 30 seconds, add captions, lead with your product in the first 3 seconds, then set up a Conversions or Traffic campaign in Meta Ads Manager.
Instagram video ads show products in motion, in context, and in real use. That's what turns browsers into buyers. Here's how to build one that works for ecommerce.
Why Video Ads Work for Ecommerce on Instagram
Video stops the scroll faster than a static image. Movement triggers a response most images can't match.
Video captures attention faster than static images
A product image is easy to scroll past. A product in motion is harder to ignore. Video buys you the seconds you need to make the pitch.
Show product in action and in real-life context
Don't just show what the product looks like. Show what it does. Show it worn, used, eaten, or applied. That context builds purchase intent fast.
Build trust through authentic product demonstrations
Shoppers buy what they believe in. A short demo answers "does this actually work?" before a customer even thinks to ask.
Instagram Feed Video Ad vs. Reels: Which Format to Choose
Your format shapes your result. Pick based on the goal you're chasing right now.
Feed video ads: Best for driving direct clicks and conversions
Feed ads sit between organic posts. They reach people already in a content-consuming mindset. They pair well with the Conversions and Traffic objectives.
Reels ads: Best for reach, discovery, and brand awareness
Per Meta for Business, Reels ads offer high engagement and feel organic to the viewing experience. They're built for reaching new audiences who don't know your brand yet.
How to decide based on your goal
Driving purchases? Start with Feed. Building awareness with a new audience? Test Reels. Many ecommerce brands run both formats at the same time.
Video Specifications and Technical Requirements
Per Meta's Ads Guide, Instagram Feed video ads have clear technical requirements. Build to these specs from the start and avoid rejection.
Recommended dimensions: 9:16 (1080x1920px) for vertical
Full-screen vertical fills the phone screen completely. Nothing competes for attention. 1080x1920px is the recommended resolution for that format.
Supported aspect ratios: 1.91:1 to 4:5
Meta's documentation states the Feed supports aspect ratios from 1.91:1 to 4:5. For most ecommerce videos, 4:5 or full vertical 9:16 performs best.
File format and duration requirements
Use MP4 or MOV. Video duration can run from 1 second to 60 minutes. For ecommerce, under 30 seconds typically performs better. Maximum file size is 4GB. Minimum width is 250 pixels, though 1080px is strongly recommended.
Text, captions, and sound guidelines
Keep primary text to 125 characters or fewer. Captions and sound are optional but strongly recommended. Many viewers scroll with sound off. Captions keep them engaged when they do.
Step-by-Step: Creating Your Instagram Video Ad
Step 1: Plan your video narrative (product demo or lifestyle)
Choose one angle: product demo or lifestyle. Demos answer "how does it work?" Lifestyle answers "who is this for?" Pick the angle that fits your product and audience.
Step 2: Film or gather footage (product shots, close-ups, context)
Shoot close-ups of the product. Add context shots of it in real use. Film vertically from the start. Sideways or incorrectly rotated videos are rejected by Meta.
Step 3: Edit for vertical format and add captions
Crop to 9:16 or 4:5. Add captions. Drop in text overlays with your key message. Keep the edit tight and the pacing fast.
Step 4: Choose your campaign objective (Conversions, Traffic, or Awareness)
Conversions drive purchase actions. Traffic drives website clicks. Both are strong for ecommerce. Pick based on where the buyer is in your funnel.
Step 5: Upload and configure targeting in Ads Manager
Open Meta Ads Manager. Create a new campaign. Select your objective. Upload your video. Set your audience, budget, and placements. Launch.
Best Practices for Ecommerce Video Ads
Grab attention in the first 3 seconds
The first 3 seconds decide if someone keeps watching. Lead with your product or your hook. Not your logo.
Mix lifestyle footage with product close-ups
Alternate lifestyle shots with tight product close-ups. That combination drives both engagement and conversions for ecommerce.
Add text overlays and captions (especially for sound-off viewing)
Text overlays deliver the message when sound is off. Always add captions. Assume silence until proven otherwise.
Keep videos under 30 seconds for fast results
Respect the viewer's time. Short videos perform better for ecommerce. Aim for 15 to 30 seconds.
Include a clear call-to-action
One CTA. Clear and direct. "Shop now." "Get yours today." "See it in action." Pick one and commit to it.

Frequently Asked Questions
What is the best video length for Instagram ecommerce ads?
Under 30 seconds. Meta's Ads Guide supports video from 1 second to 60 minutes, but ecommerce video ads typically perform better when kept short. Aim for 15 to 30 seconds.
Do I need sound in my Instagram video ad?
No. Captions and sound are optional per Meta's Ads Guide, but both are strongly recommended. Many people scroll with sound off, so captions and text overlays carry the message when audio doesn't play.
Should I use Feed video ads or Reels ads for ecommerce?
Use Feed ads when your goal is driving direct conversions or traffic. Use Reels ads when you want to reach new audiences and build awareness. Many ecommerce brands run both formats at once.
What file format should I use for Instagram video ads?
MP4 or MOV. Keep the file under 4GB. Use 1080x1920px resolution for full-screen vertical, and avoid edit lists or special boxes in the file container.
