Myth: generating video with neural networks takes seconds like images

This is a myth because video is not a single frame, but a sequence of frames, and the model must generate not only the image but also motion, temporal consistency, lighting, and often sound. In practice, most services and reviews indicate that generating a short clip usually takes 1 to 5 minutes, and for more complex scenes, it takes longer; even where "seconds" are mentioned, it usually refers to the fastest models, short clips, or interface response time, rather than full video production.[2][3][4][6]

There are also stricter limitations on the result itself: many models in 2026 confidently produce only 5–10 seconds of video, and longer clips begin to lose stability, with physics and characters "drifting," requiring them to be assembled from several short fragments in editing.[1][4][5][7] Therefore, the comparison with image generation is incorrect: an image can be obtained almost instantly, while video is already a computationally intensive process where increasing the duration sharply increases the load and waiting time.[5][12]

If you need a practical takeaway, it's this: fast — yes, in seconds like an image — usually no. For short advertising drafts, test creatives, and animated scenes, AI is already useful, but for stable, long, and plausible video, you still need either a longer render, scene cutting, or subsequent human refinement.[2][4][11]
