Getting Started with AI Video Generation [2026] — The Post-Sora Landscape, Veo/Kling, and Prompt Tips
Type some text and a video with sound is born in seconds — what would have been science fiction not long ago became reality in 2026, and the situation is changing at a frightening pace. OpenAI's Sora, which had dominated the conversation, shut down its app and web in April 2026 (with the API to follow in September); in its place Google Veo, Kling, and Runway took the lead. This up-to-date (June 2026), tool-agnostic guide covers what AI video generation is (creating moving footage from words or an image, with audio sync, 1080p–4K, and image-to-video now standard), the 2026 landscape (the Sora shutdown — reported background of compute and cost pressure and falling users — and the current leads Google Veo 3.1, Kling 3.0, and Runway Gen-4.5, with per-second pricing the norm), how it works (diffusion models extended into the time dimension; text-to-video and image-to-video), the shared 5-step workflow (choose a tool, prompt/image, set length/ratio/audio, generate and pick, join in editing), the core video-prompt tips (subject + motion + camera work + style + length + audio, with verbs and camera the keys, one cut one action, use image-to-video, run the count), what it can and cannot do yet (long pieces in one shot and full consistency remain hard, and per-second cost adds up), and the rights, watermarks, and ethics essentials (SynthID and C2PA make AI provenance standard and unremovable, purely AI output is weakly protected with country differences, commercial use depends on terms, and deepfakes of real people are off-limits). Make cuts and join them in editing rather than aiming for a long piece in one shot. Because the field moves fast, always confirm the latest officially.
