What is a video thumbnail generator?

A video thumbnail generator is a specialized tool that extracts still images from a video file at specified timestamps. The video thumbnail generator at Tool.Video allows users to select frames from any point in a video to create high-quality preview images without needing to load the entire video file.

What video formats are supported?

The platform accepts a wide variety of MP4 video files for processing. This includes standard MP4 video encoded with common codecs, such as H.264, to ensure maximum compatibility for uploading and thumbnail generation from your source videos.

How many credits does it cost?

Generating a thumbnail image at a random timestamp does not incur any cost. However, creating a custom thumbnail by specifying a particular second within the video will require one credit per thumbnail generated. The exact pricing for credit packages can be found on the Tool.Video platform.

What image formats can I export?

After generating a thumbnail, users can choose to download the image in their preferred format. The video thumbnail generator supports exporting the final thumbnail in both JPG and PNG formats to suit different project needs and quality requirements.

Can I create AI-generated cover images from thumbnails?

Once you have generated a thumbnail, further AI-powered creative options are available. Using the thumbnail image as a base, you can employ the AI Image Generator available on Tool.Video to create AI-generated cover images and other artistic variations for your content.

What is the maximum number of URLs I can process?

For free users, up to 10 video URLs can be processed in one go using the thumbnail generator tool. To process a larger batch of URLs simultaneously, users can explore the Playground API options offered by Tool.Video for more scalable solutions.

What is the maximum thumbnail resolution?

The system extracts and generates thumbnails with a maximum resolution of 4096x3072 pixels. This ensures high-quality, crisp images suitable for most professional uses, including high-definition displays and detailed previews.

Can I process URLs concurrently via API?

Yes, concurrent processing of multiple video URLs is supported through the Playground API. The platform can handle large volumes of requests efficiently, allowing for scalable, multi-threaded thumbnail generation to streamline your workflow.

What timestamp format should I use?

Timestamps should be entered as whole numbers representing seconds. For example, entering '5' will generate a thumbnail from the five-second mark of the video, while '125' would correspond to the two-minute and five-second mark.

Are there API usage limits?

The platform includes rate limiting on API requests to ensure fair usage and system stability. If you exceed these limits, your API calls may be temporarily throttled. For specific details on rate limits and quotas, please consult the official Tool.Video documentation.

How long are thumbnails stored?

Generated thumbnails are stored indefinitely on the platform's servers, ensuring your images remain accessible. You can retrieve your generated thumbnails at any time by signing into your account and accessing your generation history.
