Tips for Better AI Videos
- Be specific about camera movement: “slow pan right,” “tracking shot,” “zoom in on subject”
- Describe lighting: “golden hour,” “dramatic backlight,” “soft studio lighting”
- Specify duration and style: Include how long you want the clip and what mood
- Start with image-to-video: Upload a good starting image, then animate it
- Iterate and combine: Generate multiple short clips and edit them together
Current Limitations
AI video generation is impressive but has limitations:
- Clips are short (usually 3-20 seconds)
- Complex scenes may have artifacts
- Consistent characters across clips is challenging
- Perfect lip-sync is still evolving
- Fast-moving scenes can look unnatural
For professional content, use AI video generation as part of your workflow, not as a complete replacement for filming.
