Progressive 파일입니다만
파일을 재생해보면 장면에 따라 달라집니다.
파일은 하나인데, 장면에 따라 스캔타입이 i, ib, p로 바뀌어집니다.
유동적인데 이걸 어떻게 인코딩 해야하나 고민을 해보다가
다양한 의견을 듣고자 글을 작성해봅니다.
그리고 샤나인코딩 내 심플 정보표시에서는 progressive로 나옵니다.
아마 파일 내 정보의 스캔타입을 읽어 표시하는거라 progressive 로 나오는 거겠죠.
디인터레이스 필터를 보고 생각해봤는데
-vf "yadif=0:-1:0" 코드 중
가운데 -1이 Auto이므로, 장면에 따라 i, ib에 맞게 인터레이스 해주고
p 장면은 디인터레이스 필터가 off가 자동으로 되려나 생각도 듭니다.
아니라면 어떻게 인코딩해야할지 조언 부탁드립니다.
