📋 What the Auto Video Thumbnail Generator does

Video-to-thumbnail with AI:

• 🎬 Video input. Upload MP4, MOV, or other video formats.
• 🖼️ Reference image. Optional image to influence the thumbnail style.
• 📝 Topic and custom prompt. Guide the AI with a topic and/or detailed instructions.
• 🔢 Multiple variations. Generate 1-10 different thumbnail options per video.
• 📏 Aspect ratio control. Choose 16:9, 1:1, 4:3, 9:16, or custom ratios.

Each output includes the generated thumbnail image URL, the video source, prompt used, and timestamps.

💡 Why it matters: designing a thumbnail by hand takes 15-30 minutes per video. This Actor generates multiple professional options in seconds, so you can test which one gets the best click-through rate.

⚙️ Input

Input	Type	Default	Behavior
videoFileUrl	array	[]	Video file URL(s). Supports MP4, MOV, and other formats.
referenceImage	array	[]	Optional reference image to influence thumbnail style.
mainTopic	string	""	Main topic or theme for the thumbnail.
numberOfImages	integer	3	How many thumbnail variations to generate (1-10).
customPrompt	string	""	Specific instructions for thumbnail generation.
aspectRatio	string	"16:9"	Aspect ratio: 16:9, 1:1, 4:3, 9:16.

Example: 3 thumbnail options for a cooking video.

{
    "videoFileUrl": ["https://example.com/my-cooking-video.mp4"],
    "mainTopic": "Easy pasta recipe for beginners",
    "numberOfImages": 3,
    "aspectRatio": "16:9"
}

Example: thumbnails with reference image and custom prompt.

{
    "videoFileUrl": ["https://example.com/tech-review.mp4"],
    "referenceImage": ["https://example.com/style-reference.jpg"],
    "customPrompt": "Bold text overlay, high contrast, tech aesthetic, include product image",
    "numberOfImages": 5,
    "aspectRatio": "16:9"
}

⚠️ Good to Know: providing a reference image and custom prompt gives the AI more context and produces more targeted results. Without them, the AI generates thumbnails based on the video content and topic alone.
