In a recent exchange on Threads, Instagram boss Adam Mosseri confirmed that the platform downgrades the video quality of older content in certain scenarios. “If something isn’t watched for a long time, because the vast majority of views are in the beginning, we will move to a lower quality video,” Mosseri explained.
