Since this is likely a specific video file you've encountered, you can try these steps to find out what it is:
Direct download links from services like Google Drive or Dropbox sometimes use internal IDs in the filename.
If the video is from a public source, you can take a screenshot of a clear frame and use Google Lens to find the original post.
or tell me where you found the link? I can help you identify it if I have more context.
Right-click the file and select Properties (Windows) or Get Info (Mac) to see if there are any title or author tags.
Discord, Twitter (X), or Reddit often rename uploaded videos into similar alphanumeric strings.
Check the URL or the folder where you found the file; the surrounding text often provides the "topic."
