Every file on iStock falls into one of two collections. Essentials (everyday favorites) or Signature (premium content, exclusive to iStock). If you purchase with à la carte credits, the cost to download your video will depend on the collection it belongs to: • Essentials video clip - 6 credits (view sample clips) • Signature video clip - 18 credits (view sample clips) With a Premium + Video subscription, every asset—whether it's a video, image, or music track—will use a single subscription download.
