When is a user video scanned by Content ID to see if it matches any delivered reference material?

Content ID scans user videos as they are uploaded to immediately identify potential matches with copyrighted reference material. This proactive scanning helps prevent unauthorized use from the moment a video goes live. Additionally, Content ID performs scans at intervals later on. This ensures that if new reference material is delivered to Content ID, or if a video is edited, it can still be identified and matched against the expanding database of copyrighted content. Placing an ad or reaching a view count are not triggers for Content ID scanning. Scanning only at first upload would miss subsequent matches from new reference material or video edits.
