What Are AI Tools for Video Creators?

AI video tools use computer vision, speech recognition, and generative AI to automate the most time-consuming parts of video production: editing out silences and filler words, generating accurate subtitles, repurposing long-form content into short clips, writing scripts and descriptions, and even generating B-roll footage — work that previously required hours of manual editing.
