Frequently Asked Questions
Can AI maintain consistent product appearance across video frames?
Quality varies by model and approach. Using image-to-video mode with a high-quality product photo as input significantly improves consistency — Runway Gen-4 and most other models support this workflow. Starting from a reference image anchors the product's shape, color, and details throughout the generated clip, producing much more reliable results than text-only prompts.
How much cheaper are AI product videos vs. studio shoots?
A 30-second AI product demo costs roughly $1.50 with Runway Gen-4 ($0.05/sec), $3.00 with Veo 3 ($0.10/sec), or $3.00 with Sora 2 ($0.10/sec). Traditional studio product shoots range from $300-$1,500 per video. Teams producing 20+ product videos per month can see significant savings, though expect to generate multiple takes per product to select the best results.
Which AI generator handles product text and logos best?
Text rendering in AI-generated video remains imperfect across all models in 2026. For reliable product names, logos, and feature callouts, add text overlays in post-production using video editing tools. Runway Gen-4's workflow integrates well with post-production editing. Focus the AI generation on the product visuals and motion, then layer text on top.
Can I use AI-generated product videos for ads?
Yes. Runway Gen-4, Veo 3, and Sora 2 all grant commercial usage rights on their paid plans. For ad platforms like Meta, Google, and Amazon, AI-generated product videos work well for A/B testing multiple creative variants quickly. The main advantage is producing dozens of product video variations at a fraction of traditional production cost and time.
