- Describe lighting: Mention golden hour, overcast, neon-lit, or candlelit to set the mood
- Include motion verbs: Tell the model what should be moving and how
- Reference film styles: Mentioning cinematographic styles like "handheld documentary" or "Wes Anderson symmetrical" can influence the output
- Keep it focused: Prompts with too many elements often produce confused results
Iterating on Results
- Generate multiple variations of the same prompt to find the best result
- Use image-to-video for more control over the starting frame
- Chain short clips together for longer narratives
- Combine AI video with traditional editing for the best final product
Current Limitations to Be Aware Of
- Physics inconsistencies: Objects may float, pass through each other, or behave unexpectedly
- Temporal coherence: Characters and objects may subtly change appearance over the course of a clip
- Text and fine detail: Small text, detailed patterns, and intricate objects are often garbled
- Hand and finger rendering: While improved, hands remain a challenge
- Audio: None of these tools generate synchronized audio (you need to add it separately)
The Future of AI Video
The pace of improvement in AI video generation is staggering. Each major model update delivers noticeably better quality, longer durations, and more control. Several trends are shaping the future:
- Longer generation: Multiple companies are working toward generating minutes-long coherent video
