Part 2. How to Generate Image or Text to Videos with AI

Knowing the correct process involves understanding the workflow from a simple prompt to a finished export. Using Kling AI as an example, you can transform a static image into a cinematic masterpiece.

Step by Step Guide for Kling AI:

• Select Input Mode: Choose between “Text to Video” or “Image to Video.” For the most control, upload a reference image to lock in your subject’s appearance.

• Enter Your Prompt: Describe the action clearly. Use descriptive words for lighting, camera angle, and motion (e.g., “Cinematic slow motion, golden hour lighting, hair blowing in the wind”). And also add sound effects.

  

• Adjust Settings: Select between Standard Mode and Professional Mode. Choose the clip duration (5, 10, or 15 seconds), the aspect ratio (16:9 for YouTube or 9:16 for TikTok), and the generation count.

  

• Generate and Refine: Hit “Generate” and wait for the render. If the motion is slightly off, use the “extend” feature or re-prompt to fix artifacts.

Choosing the right text to video AI tool depends on your project needs. In 2026, you should consider the following criteria:

• Visual Output Quality: Determine if your project requires 4K resolution (Runway, Veo) or if 720p is sufficient for social media (Pika, Hailuo).
• Physics and Motion: Platforms like Kling and Hailuo are superior for human movement, while Luma excels at camera pans.
• Audio Features: If you need synchronized sound, prioritize platforms with native audio engines like Pika or Veo.
• Control and Customization: Professional workflows benefit from “Motion Brushes” and “Camera Controls” found in Runway and Luma.
