What’s the difference between text-to-video and avatar-based generators?
Text-to-video generators (like Runway and Pika) create entirely new video content from text descriptions, generating scenes, objects, and movements from scratch. Avatar-based platforms (like Synthesia and HeyGen) use AI-powered digital humans to deliver scripted content, perfect for presentations, training videos, and marketing materials.
Which AI video generator offers the best free plan?
Pika Labs currently offers the most generous free tier with daily credits for video generation. Runway provides a limited free trial with watermarks. HeyGen offers 1 free credit monthly, while Synthesia provides a free demo but requires a paid plan for full access.
What’s the typical video quality and length I can expect?
Quality varies by platform and plan. Runway Gen-3 produces up to 4K resolution with 10-second clips. Pika generates 3-second clips at 1080p. Synthesia and HeyGen can create videos of any length (based on your plan) at 1080p or 4K.
Can I use AI-generated videos commercially?
