Text-to-video is the narrowest and hardest job in AI video: no reference image, no source footage, just a description turned into moving frames that have to stay physically coherent. That coherence is the whole game. Cheaper models produce a convincing first second and then drift — limbs detach, faces reset, objects pass through each other — which is why motion consistency, not resolution, is the honest benchmark. Clip length compounds the problem, since holding a scene together for sixteen seconds is significantly harder than for five.

The newest development worth understanding is audio. Until recently every text-to-video model returned a silent clip you had to score separately; Vidu's Q3 model generates dialogue, effects and music synchronised with the footage in a single pass, and Google Veo 3 produces native audio at the top end. If your content has a voice, that removes an entire production step. If it does not, prioritise motion quality and clip length instead, and treat audio generation as a bonus rather than a deciding factor.
