When I put my video in my svg it loads successfully, but when I upload it to a live server the video doesn't load, although it works fine when it's not hosted dynamically.

There could be several reasons for this issue. Here are a few things you can check:

1. Check if the video file path is correct: If the file path is wrong, the video won't load. Make sure you have specified the correct path to the video file in your SVG code.

2. Check server settings: Some servers have restrictions on the types of files you can upload. Make sure your server allows you to upload video files.

3. Check MIME type settings: Make sure the server is properly configured to serve the correct MIME type for the video file. This can affect how the browser interprets the file and whether it can play it.

4. Check browser compatibility: Some browsers may have issues loading videos embedded in SVG files. Test your page on different browsers to see if the issue persists.

5. Check file permissions: Make sure that the video file has the correct permissions to be accessed by the server and the browser.

Overall, it's difficult to pinpoint the exact issue without more information about your setup. You may need to troubleshoot using the above suggestions or seek assistance from a web development expert.
