매장시연 영상때문에 이런종류의 영상을 다수 가지고 있습니다.

 

해상도는 4k uhd 이구요

 

이런걸 30fps 20000Kbps (20Mbps) FHD 로 변경하려고 합니다

 

형식은 TS나 TP 코덱은 MPEG2 으로 할꺼구요..

 

근데 리사이즈 필터를 잘못골랐는지 아래처럼 깍두기 현상이 일어납니다 ㅠ_ㅠ

인코딩한 경로는

 

Wondershare Video Converter Ultimate 인데

 

이걸 Xvid , 풀HD, 비트레이트 30000Kbps (30Mbps) 로 인코딩후

 

샤나인코더로 TS, MPEG2, 풀HD 비트레이트 18000Kbps (18Mbps)로 인코딩을 했습니다.

 

필터는 neighbor 로 했구요.

 

기본값 bicubic 으로 해도 좀 별로인거 같아서... 인코딩느리면 당연히 연산을 많이해서 지글지글한거 없이

 

깔끔하게 보여질줄 알았는데 그게 아니네요 ㅠ.ㅠ

 

인코딩시간 정말 오래 걸려도 좋으니 20Mbps, TS, 풀 HD로 했을때 화질 정말 좋게 인코딩할수 있는 방법이 없을까요?

 

안그러면 샤나인코더에서 UHD (4K) 영상을 바로  풀HD로 할수는 없는건가요 ㅠㅠ?

 

 

20Mbps로 제한하는 이유가

이 기계를 통해서 HDMI 분배기로 영상을 나눠주거든요. 그래서 이 기기가 TS나 TP형식으로 20Mbps MPEG2 로 하면 안끊기고 잘됩니다. (인코딩은 고정비트레이트로 해야됨)

 

그런데 AVI XVID 18Mbps 로 하면 (아마 연산처리능력이 딸리는지) 영상이 끊기더라구요..

 

고수님들 제발좀 부탁좀드립니다 ㅠ 도와주세요 ㅠ

 

 

원본영상 끊기시는부는 다음팟 64비트설치후 화면에서 오른쪽클릭후 필터에서 내장 DXVA 선택하시면 안끊길껍니다.

 

참고로 저는 i5 4460 , 메모리 16기가에 GTX960 입니다.
