Runway's generative video models and editing suite are aimed at filmmakers and creatives who want control over motion and style.
Keep in mind: Credit-based; iterating on a shot can use credits fast.

The best AI video generators
AI video generators fall into two groups: generative tools that create new footage from a prompt or image, and avatar tools that turn a script into a presenter-style video. Know which one you need before comparing.

The picks, in detail
Luma's Dream Machine generates realistic short clips from prompts or still images, and is easy to start with in the browser.
Keep in mind: Clips are short; longer stories mean stitching scenes together.
Pika makes it simple to animate images and create short stylized clips and effects, popular for social content.
Keep in mind: Better for short creative clips than long, consistent scenes.
Synthesia turns a script into a video with an AI avatar presenter in many languages, without cameras or studios. Common for training, onboarding and internal comms.
Keep in mind: Designed for presenter videos, not cinematic generation.
HeyGen creates avatar videos and translates existing videos with voice and lip sync, useful for marketing and multilingual content.
Keep in mind: Avatar realism varies with the avatar and script; preview before committing.
How to choose
- Decide first: generated footage, or a talking presenter?
- Compare the same prompt across tools; results vary a lot by subject.
- Check commercial-use rights and watermark rules on free tiers.
- For presenter videos, pair with a strong voice (ElevenLabs integrates with many workflows).
