AI for Explainer Videos (2026)

Explainer videos used to cost $5K and take 3 weeks; AI video platforms now ship a 60-second explainer in 30 minutes. HeyGen and Synthesia generate AI-avatar talking-head videos in 100+ languages; Runway and Pika handle scene-based generative video; D-ID animates static photos into talking videos. The win is replacing slow scriptwriter-to-storyboard-to-shoot loops with prompt-to-render workflows.
