Hello, I'm John of Reading. An edit that you recently made to Digital video fingerprinting seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! John of Reading (talk) 07:42, 20 November 2023 (UTC)
