> Quick answer: Define your hook first. Feed your brand data to an AI platform. Export at 9:16 for Reels, Feed, or Stories. Add captions for silent viewers. Test variants to find what converts.
Why AI Video Generation Works for Instagram Ads
Video now accounts for over 60% of user time on Instagram. AI cuts production from days to minutes without sacrificing brand consistency.
Video dominates Instagram engagement
More than 60% of user time on Instagram goes to video content. Static images and text posts compete for a fraction of that attention. Short-form formats like Reels also receive priority placement in the feed algorithm.
AI acceleration cuts production time and cost
Traditional video production takes days and costs thousands. AI generation handles scripting, visual creation, and caption drafts in one pass. You go from idea to draft in minutes.
Authenticity and native format matter more than slickness
Over-produced ads feel out of place in a Reels feed. Platform-native creative performs better than broadcast-quality content. AI tools trained on your brand data keep the tone genuine and the style familiar.
Platform Specs Before You Generate. Instagram Video Placements
Wrong dimensions mean rejection or cropped content. Lock in the specs before you start generating.
Instagram Feed videos
Per Meta's Ads Guide, Feed video ads require MP4 or MOV format at 9:16 aspect ratio and 1080x1920px resolution. Duration runs from 1 second to 60 minutes. File size limit is 4GB.
Instagram Reels
Meta's Ads Guide specifies 9:16 aspect ratio at 1440x2560px for Reels ads. Duration caps at 15 minutes. Safe zones are critical. keep all content out of the top 14%, bottom 35%, and 6% on each side.
Instagram Stories
Per the Meta Business Help Center, Stories ads use 9:16 aspect ratio at 1080x1920px. Vertical fullscreen is the recommended format for maximum impact.
File size limits and safe zones
Every placement caps at 4GB. Reels safe zones are the most restrictive. Always preview the exported file in portrait mode before uploading.
The AI Video Generation Workflow
Six steps take you from blank screen to a ready-to-launch video ad.
Step 1. Define your hook
The first 0-3 seconds decide everything. Plan a bold visual, unexpected motion, or a direct text question before you open any tool.
Step 2. Feed your brand info and product URL to AI generation
Use Coinis Image Ads to pull in your product URL. The platform reads your product details and Brand Profile to inform tone, messaging, and visual direction automatically.
Step 3. Let AI generate script, visuals, and captions
AI handles scripting, asset selection, and caption drafts together. Coinis routes each task to cutting-edge AI models so you don't have to configure anything.
Step 4. Add captions or sound
Captions are not optional in practice. Meta recommends them for Reels and Stories. Silent viewing is the default behavior for most users. Write captions that carry the full message on their own.
For Reels, you cannot use licensed music. Use original audio or tracks from Meta's Sound Collection instead.
Step 5. Export in the right aspect ratio and file format
Export as MP4 at 9:16. Match the resolution to the placement. 1080x1920px for Feed and Stories, 1440x2560px for Reels. Run a silent preview to confirm captions and safe zones are clear.
Step 6. Test variants and measure performance
Generate at least two or three versions with different hooks or caption styles. Performance data tells you what to keep and what to cut.
Critical Best Practices for Sound-Off Viewing
Sound-off is the default. Design every video for it first.
85% of viewers watch without sound
Research confirms that 85% of Instagram users scroll with sound off. Captions and on-screen text are your primary message delivery channel, not audio.
Use text overlays sparingly
One clear message per screen beats three competing text blocks. Keep overlays inside the safe zones. Cluttered text fails on small screens.
Visual storytelling trumps voiceover alone
Show the product in action. Show the transformation. Motion and visuals carry the story when audio is absent.
Original or royalty-free audio only
Reels ads reject licensed tracks. Use original audio or Meta Sound Collection. This rule applies to music beds and featured tracks alike.
Generating Video Variations for Testing
One video is a guess. Multiple variants become a strategy.
AI tools let you generate multiple hooks, scripts, and styles
Coinis Image Ads generates multiple creative directions in one session. Different hooks, different caption tones, different visual styles. All from the same product URL.
Test Reels vs. Feed format to find what drives engagement
Reels and Feed attract different viewer behaviors. Test both before committing budget to one placement type.
A/B test captions, visual styles, and CTA placement
Change one element per variant. Caption position, CTA copy, hook style. Isolate the variable to trust the result.
Use Brand Profile to keep voice consistent across variants
Coinis Brand Profile learns your tone, color palette, and messaging priorities. Every generated variant stays on-brand automatically.
From Generation to Launch
Final checks matter as much as the generation step itself.
Review exported video for brand alignment and safe zones
Watch the full video in portrait mode. Check the Reels safe zones. Confirm the hook lands before the three-second mark.
Test captions and audio in mute mode before uploading
Mute your phone and watch the video. If the message lands without sound, the ad is ready to upload.
Use Campaign Launcher to publish and track performance
Coinis Campaign Launcher publishes directly to Facebook and Instagram. You track CTR, completion rate, and conversion data from the Advertise page.
Iterate based on CTR, completion rate, and conversion data

It depends on the placement. Feed video ads support 1 second to 60 minutes. Reels ads cap at 15 minutes. Stories ads are optimized for short, vertical fullscreen clips. For paid ads, shorter content with a strong hook in the first 3 seconds typically drives better completion rates.
