Buyer's Guide

AI video splits into two camps. Avatar/presenter tools (Synthesia, HeyGen) turn a script into a talking-head video — ideal for training, explainers, and social. Generative video (Runway) creates cinematic B-roll and effects from prompts. Choose by use case: pick an avatar tool for spokesperson content at scale, or a generative tool for creative footage. Key factors: avatar realism, voice/language coverage, editing control, render speed, and per-minute cost.
