Frequently Asked Questions
Can AI maintain consistent product appearance across video frames?
Yes, but quality varies significantly. VidScore's object consistency benchmark shows Runway Gen-4 at 95%, Veo 3.1 at 93%, and Sora 2 at 91%. Budget models like Minimax Hailuo drop to 78%. For product demos, we recommend using image-to-video mode with a high-quality product photo as input — this improves consistency by 15-20% across all models.
How much cheaper are AI product videos vs. studio shoots?
VidScore's cost analysis shows AI product demos cost $2-$8 per 30-second video vs. $300-$1,500 for studio shoots. Runway Gen-4 costs approximately $1.20 per 30-second clip. Teams producing 20+ product videos per month save 90%+ by switching to AI generation, based on our ROI calculator data.
Which AI generator handles product text and logos best?
Text rendering remains a challenge for AI video in 2026. VidScore's text legibility test shows Sora 2 at 72% accuracy, Veo 3.1 at 68%, and others below 60%. We recommend adding text overlays in post-production for reliable results. Runway Gen-4's compositing tools make this workflow easiest.
