안녕하세요 샤나인코더를 사용하면서 발생한 문제점 때문에 이렇게 글을 작성합니다.
저는 기존영상의 화질 열화보다는 용량의 감소에 초점을 두고 이것저것 검색해보면서 알아낸 세팅으로 인코딩을 하였습니다.
(사실 인코딩이 뭔지 아직도 정확히 모르겠습니다만... 일단은 인코딩이라 하겠습니다.)
그런데 모든 영상이 그런건 아니지만 몇가지 영상의 경우 영상 초반에 짧게는 10분 길게는 영상 총 길이의 10% 가량이 검은화면으로 나오는 현상을 발견했습니다. 소리는 나오고 화면만 검은색으로 나오길래 제 딴에는 구글링을 열심히 해봤지만 저에게 정확히 걸맞는 정보는 나오지 않더라구요
그래서 이렇게 글을 작성하게 됩니다. 혹시 아시는분이 있다면 댓글 남겨주시면 감사하겠습니다 ㅠㅠ
(제가 인코딩 한 후에 샤나인코더를 바로 꺼서 '기록보기'는 안되네요 ㅠㅠ 필요하시면 다시 해서 올리겠습니다!)
혹시 모를 2줄 요약
1. 인코딩을 하면 소수의 영상들이 영상 초반 검은화면이 나옴
2. 아시는분 계신가요

미디어작성날짜를 유지하며서 인코딩 하는 방법은 없을까요?
