Why Polish Kills Conversion on TikTok and Instagram
In performance advertising on TikTok, Instagram, and YouTube Shorts, high-budget corporate commercials consistently get skipped. UGC (User-Generated Content) — videos shot on smartphone front cameras with casual natural lighting — converts 300% to 500% better.
Creating realistic UGC with AI requires you to un-learn cinematic perfection. You must instruct the AI to mimic smartphone camera hardware and candid creator behaviors.
The UGC Prompt Engineering Formula
To make an AI video look like real iPhone footage:
1.Specify Smartphone Hardware: Use terms like
iPhone 15 front selfie camera, 4k 60fps mobile recording, natural room ambient light, unedited raw vlog aesthetic.2.Add Micro-Movements:
Subtle natural hand tremor, subject adjusting the phone angle slightly, casual eye contact with lens.3.Avoid Overly Dramatic Lighting: Use
soft daylight coming through a living room window, ring light reflection in eyes, typical home interior bedroom.Ready-to-Test UGC Prompt
