It seems like you're looking for a way to add a vector background to a weather video. One possible solution is to use a library that can handle vector graphics, such as @upstash/vector.

Here's an example of how you could use it to download a product with vector graphics and then use the resulting image as a background in your video:

import io.upstash.vector.VectorClient;

// Create a new VectorClient instance
VectorClient vectorClient = new VectorClient("https://your-vector-db.com");

// Download a product with vector graphics
vectorClient.getVector("product-id", "png").then((response) -> {
    // Load the image from the response
    java.awt.image.BufferedImage image = javax.imageio.ImageIO.read(new java.io.ByteArrayInputStream(response.getBytes()));

    // Get the dimensions of the image
    int width = image.getWidth();
    int height = image.getHeight();

    // Create a new video with the vector background
    // (This part would require additional libraries and code, as it's not directly related to @upstash/vector)
});

Please note that this is just an example, and you'll need to adapt it to your specific use case. Additionally, you may want to consider using a more robust library for handling video processing, such as react-native-compressor or expo-video-processors.
