Resolve Meta Ad Aspect Error

Job ID: 40503412

Budget: ₹600 – ₹1,500 INR

My 9:16 ecommerce video keeps getting kicked back by Meta Ads Manager with an “incorrect aspect-ratio” warning even though the file itself is compliant. The clip is an MP4, I have already tried exporting it at several resolutions, and the rejection still happens. I suspect something in the file format or encoding is tripping the checker, but I need fresh eyes on the entire chain—creative, placements, and account configuration—to uncover the real culprit.

You would:
• Inspect the MP4’s metadata, codecs, and any hidden padding that could confuse Meta’s validator.
• Cross-check every ad-set setting (automatic placements, Reel eligibility, mobile feed, etc.) to confirm nothing forces a conflicting crop.
• Verify that the account’s catalog and pixel events align with a vertical-video campaign so nothing else blocks approval.
• Deliver a corrected upload that clears Meta review and starts spending without throttling.

Acceptance will be simple: once the creative is live, fully approved, and delivering impressions on Facebook Reels and Instagram Stories, the job is complete.

I’m only interested in someone who has already solved this exact headache before, so please reference a similar fix when you respond.
