인코딩 이후 동영상 스킵시(재생바에서 마우스로 앞뒤로 몇초 이상 이동) 화면이 일시 정지한 느낌으로 1초~2초 정지가 되었다가 다시 정상적으로 나옵니다.'
어떤 지점은 0.1초 어떤 지점은 1초 등등 이동 지점에 따라 정지되는 시간은 다릅니다.
동영상 플레이어는 "팟플레이어" 그리고 "Mpc-be" 이고, 탐색시 "키프레임 단위로 이동"은 해제된 상태입니다.
하지만 해제된 동일한 조건에서 원본에서는 딜레이가 안생지만, 인코딩 된 영상에만 딜레이가 발생합니다.
"키프레임 단위로 이동"을 체크하면 정지되는 시간이 0.1초~0.2초 정도 아주 짧게 정지됩니다.
원본이나 인코딩본 모두 스킵 없이 그냥 볼때에는 끊김이나 딜레이 없이 정상적으로 나옵니다.
회원님들의 도움이 꼭 필요합니다.
인코딩할 자료는 많은데...
모두 좋은 하루 되세요.**
참고적으로 저와 같은 문제가 발생해서, 다른 회원님이 이미 질문을 올렸는데 미해결 같습니다.

MediaInfoLib - v19.09
구간설정 미리보기에서 I프래임을 크릭할 경우 자동으로 I 프레임...
4k영상 인코딩 설정 한번만 봐주세요~! (너무 오래 걸립니다 ㅠㅠ)
팟플레이어, MPC-BE에서 동영상 탐색 시 지연 발생은 해당 플레이어에서 원하는 위치로 탐색하는데 걸리는 시간으로 보입니다.
키 프레임 단위로 이동하게 되면 키 프레임은 완전한 이미지를 가지고 있으므로 지연 시간이 적지만 키 프레임이 아닌 프레임을 탐색하게 되면 완전한 이미지를 가지고 있지 않으므로 완전한 이미지를 만들어야 하며 완전한 이미지를 만들 때까지 시간이 걸리게 됩니다.
이 시간은 해당 영상이 얼마나 높게 압축되어 있고 어떤 코덱인가에 따라 다르고, 키 프레임 간격에 따라서도 다르며 하드디스크와 여러 가지 하드웨어 상태에 따라 시간 차이가 발생하게 됩니다.
키 프레임 간격이 길면 이론적으로 용량이 적어지며 탐색시간이 길게 되고, 키 프레임 간격이 짧으면 용량이 많아지며 탐색시간이 짧아지게 됩니다.
샤나인코더 빠른 설정에서 키 프레임 변경 항목에서 설정 가능하며 단위는 초 단위입니다.
샤나인코더 5.0 버전을 사용하는 것으로 봐서는 샤나인코더 5.1 버전부터 추가된 기능인 정확한 탐색 기능이 없으므로 샤나인코더 자체 문제는 아닌 것으로 보입니다.
샤나인코더 5.1 버전부터 미리 보기, 파일 재생, 구간 설정에서 키 프레임 탐색이 아닌 정확한 탐색 기능이 추가되었고 기본적으로 키 프레임 탐색이 꺼져 있으므로 해당 버전으로 업그레이드 한 다음에 샤나인코더 5.0 버전으로 인코딩된 파일을 추가하여 목록에서 오른쪽 버튼을 누르고 파일 재생을 한 뒤 탐색을 해보세요.
(샤나인코더 5.1 버전에서 환경 설정 -> 키 프레임 탐색 사용을 통해 키 프레임 탐색 여부를 선택할 수 있습니다.)
샤나인코더 5.1 버전에서 키 프레임 탐색 사용에 체크가 되지 않은 상태(정확한 탐색 사용)로 파일 재생 시 지연 시간이 발생한다면 하드웨어 성능에 따른 지연으로 보입니다.
