QastX for marketplace sellers: product videos that drive sales
AI clips your long product demos into short, punchy videos for Amazon, Etsy, Shopify listings and short-form feeds — driving more clicks and conversions.
Listings with short product videos convert dramatically better than image-only listings. The problem is production: hiring a video editor for every SKU is expensive, and doing it yourself takes hours. QastX makes product video fast. Record a demo of your product — unboxing, how-to, benefits walk-through — and QastX clips it into the right length for Amazon listing videos, Etsy video thumbnails, Shopify embed, and short-form platform ads. One recording session covers all your distribution channels.
