Archiving Event Highlights for Research

Hello event planning professionals! I manage logistics for a large-scale international conference circuit, and a significant portion of our post-event evaluation involves studying how attendees, speakers, and sponsors document live happenings on social channels. We want to archive public media highlights, behind-the-scenes clips, and venue spotlights to review for our next annual planning summit. However, trying to manually record or screenshot every single temporary update across dozens of separate public profiles during the live event is practically impossible for our small team. Are there effective methods to review and save these public event media logs efficiently?
