Cov lus nug nquag
Dab tsi yog qhov txawv ntawm transcoding thiab converting video ntaub ntawv?
Thaum feem ntau siv sib hloov, cov ntsiab lus no muaj kev hloov maj mam tab sis tseem ceeb sib txawv hauv cov ntsiab lus kev tshaj lij. Video hloov dua siab tshiab feem ntau yog hais txog kev hloov cov yees duab los ntawm ib hom ntawv mus rau lwm qhov, uas tej zaum yuav hloov lub thawv (xws li MOV rau MP4), codec, daws teeb meem, lossis lwm yam tsis. Nws yog lub ntsiab lus dav dav uas suav nrog ntau hom kev hloov pauv.
Kev hloov pauv, more specifically, refers to decoding a video from one codec and re-encoding it to another codec. This is a type of conversion that focuses particularly on the encoding process rather than just changing containers or metadata. For example, converting H.264 to H.265/HEVC would be transcoding.
Hauv kev ua haujlwm tshaj lij, koj tuaj yeem ntsib transmuxing (hloov lub thawv yam tsis rov encoding cov kwj video) thiab transsizing (hloov qhov kev daws teeb meem). Cov no yog txhua daim ntawv tshwj xeeb ntawm kev hloov pauv video uas cov kws tshaj lij paub qhov txawv raws li qhov tshwj xeeb hloov pauv tau ua thiab kev ua tiav yuav tsum tau ua.
