• Maintain brand consistency: Never publish a generic-looking AI video. Always customize the output by adding your official logo, specific brand colors, and unique fonts to the template. Ensure every video ad reflects your distinct brand identity.
• Perform strict quality control: Always treat the AI-generated video as a draft. Scrutinize the script, voiceover, and visuals for complete accuracy, logical coherence, and brand-safe messaging. Apply final polish using the platform's or external editing tools.
• Leverage rapid A/B testing: Capitalize on the generator's speed to produce multiple ad versions quickly. Create variations with different hooks, calls-to-action (CTAs), and visual styles. Test these to instantly discover which creative work drives the highest conversions.
• Optimize for platform & format: Before exporting, ensure the final video is correctly resized for its intended platform. Use vertical formats (9:16) for reels/shorts and square (1:1) for feeds to maximize full-screen viewing and audience engagement on each social channel.
