Unity Integration Examples

Example 1: Cutscene Generator

public class CutsceneGenerator : MonoBehaviour
{
    public async UniTask<VideoClip> GenerateCutscene(string description)
    {
        return await description
            .GENVideo()
            .SetDuration(15f)
            .ExecuteAsync();
    }
}

Example 2: Background Video

public class BackgroundVideoGenerator : MonoBehaviour
{
    public async UniTask SetBackground(string environment)
    {
        VideoClip bg = await $"Looping {environment} background"
            .GENVideo()
            .SetDuration(30f)
            .ExecuteAsync();
        
        // Apply to video player
        videoPlayer.clip = bg;
        videoPlayer.isLooping = true;
        videoPlayer.Play();
    }
}

Prompt Tips

✅ Good Prompts

// ✅ Specific and descriptive
"Smooth camera pan across medieval castle at golden hour"

// ✅ Include motion details
"Slow zoom into glowing crystal, particles floating around"

// ✅ Describe timing
"Quick cut between city scenes, fast-paced montage"

❌ Bad Prompts

// ❌ Too vague
"video"

// ❌ Too complex
"entire movie plot with multiple scenes and characters"

Limitations

1. Duration: Typically limited to 10-30 seconds

2. Quality: May not match professional video

3. Consistency: Character/object consistency across frames

4. Cost: Expensive compared to image generation
