What Is an Explainer Video? Types and Ideal Lengths
AI video
An explainer video makes one idea clear in about 60 to 120 seconds, pairing a spoken script with simple visuals. AI video tools render one from a script, PDF, or URL as a narrated 1080p MP4 with word-synced captions, which is also how faceless YouTube channels, training videos, and camera-free video podcasts get made.
