W Player는 원활한 전환을 위해 Back Page layer와 Front Page layer에 총 2개의 페이지를 로드합니다. Back Page layer와 Front Page layer에 위치한 비디오 개수가 3을 초과하는 경우 정상적으로 재생되지 않으므로 비디오 개수를 3개 이하가 되도록 조정하세요. 만약, 저작 시 Web content 속성 중 sync timeline을 설정하면 Front page layer에서만 (play 단계) video를 load 함으로 재생 제약을 극복 할 수 있습니다. 단, play 단계에서 재생 시점에 깜박임이 발생 할 수 있습니다. ▶ W Player API 설정하기
