Best AI video generation quality available - Gen-3 Alpha produces genuinely cinematic clips
Full creative suite beyond just generation: green screen, inpainting, motion tracking, slow-mo
Image-to-video and video-to-video modes give versatile creative options
Academy Award-recognized technology trusted by film studios and agencies
Regular model updates with significant quality improvements between generations

Video clips limited to 5-10 seconds per generation - building longer content is costly
Credits burn quickly for video generation, making heavy use expensive
Text rendering in generated videos is unreliable and often garbled
No audio generation - you need separate tools for sound and music
Specific face control is limited - don't expect consistent character portrayals across clips

Fastest way to produce professional training and corporate videos - script to finished video in minutes
140+ language support with natural-sounding voices makes global content creation trivially easy
230+ avatars with convincing lip sync and gestures that actually look human
Custom avatar and voice cloning let you scale a specific presenter across hundreds of videos
Massive time and cost savings over traditional video production for repetitive content types

Limited to talking-head format - don't expect cinematic or creative video styles
Per-minute video costs add up fast for teams producing high volumes of content
Built-in editor is basic - complex projects need finishing in external tools
Some avatars still hit the uncanny valley, especially with complex facial expressions
No real-time generation - you submit a job and wait for rendering, which can take minutes
