Honest Limitations of AI Video in 2026
- 5-10 second clips are the practical maximum on most providers
- Consistency across clips is hard (characters, settings, lighting drift)
- Text rendering in video is weak across all providers
- Hands and faces require careful prompting
- Specific brands/celebrities are restricted
- Audio sync for lip movement is limited
For feature-film quality and length, AI video in 2026 is not there yet. For social media, marketing, and short demos, it absolutely is.
