AI Video Editor Tool - Magic Hour Docs

​

Overview

​

How It Works

1. Upload a source video - Use the file upload API and copy its file_path
2. Describe the edit - Provide a prompt such as “Change the car color to blue”
3. Choose the clip range - Set start_seconds and end_seconds
4. Create the job - Submit the edit and poll until its status is complete
5. Download the result - Retrieve the edited video from downloads

​

Use Cases

• Object removal - Remove distracting people, props, logos, or background details
• Scene changes - Replace backgrounds or add new visual elements
• Color and lighting edits - Change colors, lighting, and other scene details
• Creative restyling - Turn footage into cinematic, illustrated, or branded variants
• Ad variants - Produce multiple edits from one source clip

​

Best Practices

• Write one clear edit - A focused instruction is easier to apply consistently than several unrelated changes
• Name the subject - Identify the object, person, or region you want changed
• Describe the result - State the desired color, object, environment, or visual style
• Use clear footage - Stable motion, good lighting, and visible subjects improve consistency
• Review the full clip - Check transitions and fast-moving details before using the output
