What Are AI Video Tools?
AI video tools use artificial intelligence to automate or enhance video creation/editing. They can generate videos from text prompts, images, or audio, and edit existing content with effects, transitions, and avatars.
Categories of AI Video Tools
1. AI Video Generators
Create entire videos from scratch using text, images, or audio.
Examples: Runway Gen‑4, Google Veo 3, Kling AI, Pika Labs.

- Google Veo 3: Google’s DeepMind model now supports native audio generation—dialogue, sound‐effects, ambient noise—all in one
- Kling 2.1: Excels at image-to-video realism and motion coherence, seen as a challenger to Veo 3
- Pika Labs: Fast, accessible video clips (3–4 sec), ideal for creative freedom and quick outputs
2. AI Video Editors
Enhance or automate editing—adding transitions, subtitles, effects.
- Adobe Firefly: Text-to-video for B-roll and assets.
- Descript: Edit videos by simply editing the transcript.
