Text-to-Video Creation Guide

The Text to Video feature is perhaps the most magical aspect of WanVideo, allowing you to manifest your imagination with just words. Here's how to get the best results:

Crafting Effective Prompts

The quality of your text prompt directly influences the quality of your video. Follow these guidelines:

1. Be Specific: "A red sports car driving fast on a coastal highway at sunset" works better than "a car driving"

2. Include Visual Details: Mention colors, lighting, weather, and atmosphere

3. Describe Movement: Specify how objects should move ("swaying gently," "racing quickly")

4. Set the Scene: Include background elements and environment details

5. Consider Style: Add artistic direction like "photorealistic," "anime style," or "cinematic"

Sample Prompt Template

[Subject] [action] in/on [location] with [details] during [time of day], [style reference]

Example: "A majestic eagle soaring over snow-capped mountains with sunlight glinting off its wings during golden hour, cinematic quality"

Adjusting Parameters

WanVideo allows you to fine-tune several generation parameters:

• Video Length: Typically 5-10 seconds (longer videos may lose coherence)
• Resolution: 480p is standard, with 720p available for premium users
• Guidance Scale: Controls how closely the AI follows your prompt (higher values = more literal interpretation)
• Seed: Save this number to recreate similar videos in the future

Iterative Refinement

Don't expect perfect results on your first try. The best approach is iterative:

1. Start with a basic prompt
2. Review the generated video
3. Refine your prompt based on what worked and what didn't
4. Generate again
5. Repeat until satisfied

Image-to-Video Transformation

The Image to Video feature allows you to animate static images, bringing photographs, illustrations, or AI-generated images to life. Here's how to use it effectively:

Choosing the Right Base Image

Not all images are equally suitable for animation. The best candidates have:

• Clear subjects with defined boundaries
• Some implied motion potential
• Good composition with foreground and background elements
• High resolution and quality

Avoid images that are already blurry, have multiple overlapping subjects, or extremely complex scenes.

Setting Motion Parameters

WanVideo gives you control over how your image animates:

• Motion Strength: Determines how dramatic the movement will be
• Motion Direction: Guides the primary direction of movement
• Focus Point: Indicates which part of the image should be the center of animation
• Duration: Sets how long the resulting video will be

Adding Supplementary Text

You can enhance your image-to-video conversion by adding descriptive text:

1. Upload your image
2. Add a text description of the desired motion and effects
3. Adjust parameters as needed
4. Generate your video

This combination of visual and textual input often produces the most impressive results.

Post-Processing Options

After generating your video, WanVideo offers several post-processing options:

• Adjusting playback speed
• Adding transitions
• Applying filters
• Incorporating text overlays
• Adding background music or sound effects

These finishing touches can elevate your creation from impressive to professional.
