What are the best AI video generation tools in 2026?
The best open-source AI video generation tools in 2026 build on image diffusion: AnimateDiff adds motion to Stable Diffusion models, Deforum creates prompt-driven animation, and ComfyUI hosts the most powerful video workflows. For practical editing, tools like Whisper for transcription and TTS engines for narration complete the pipeline. These run locally for free, though longer/higher-res generation needs a capable GPU.
