Layisha phezulu ifayili yakho MP4 kwaye umguquli uqhuba i-CRF-esekelwe kwakhona-ukukopela ukujolisa kwi-visually-lossless DivX imveliso (CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne DivX isiqulathi seefayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 ye-newer pipelines. I-MP4 eninzi eluhlaza yi-H.264 yevidiyo enesandi se-AAC; isiqulathi seefayili sigcina ngokusemthethweni i-HEVC, i-AV1 ne-VP9. Imixholo ye-DivX yi-MPEG-4 Inxalenye ye-2 yevidiyo, eqhelekileyo ijikelezwe kwi-AVI, ene-MP3 okanye i-AC-3 yesandi ecaleni kwayo.

Yintoni eyenza i-subtitle tracks kwifayili yam MP4?

Ayikwazi ukuhlala ikhethiwe, kuba DivX ayinayo i-soft-subtitle stream ukubeka i-subtitles. Zikhona iindlela ezimbini zokuphuma: ukutshabalalisa kwividiyo ngexesha lokuguqula, okwenza ukuba zihlala zihlala kwaye zingatshintshwa, okanye urhweba ngaphandle njenge.srt eyahlukileyo ecaleni kwe DivX ukuze umdlali alayishe.

DivX iphatha yonke imijelo yesandi njengento ephambili, ngoko udidi lwesivakalisi sokuqala, i-dub kunye nomlawuli wengxelo ingaphila kwifayile enye nomdlali otshintshela phakathi kwabo kwisicelo. Abadlali be-DVD abaqinisekisiweyo be-DivX bahlala beqhelekileyo, kwaye i-codec ihlala i-floor yokulungelelanisa udidi olupheleleyo lwezixhobo zekhompyutha ezisetiweyo.

Ndingayifaka njani ifayili kwiphepha le-web emva kokuguqula i-MP4 ibe yi-DivX?

Ayi ngqo. MP4 idlala umgca kwisixhobo sokukhangela yonke; DivX ayisebenzi, ngoko ke iphepha elidibanisa ibuyela umva kwikhonkco lokulayisha okanye isakhelo somdlali ongenanto. Ukuba ifayile icwangciswe kwiwebhusayithi, gcina i MP4 kwi-web kwaye uthathe i DivX njenge-archive okanye uhlela ikopi.

DivX ihlala ibuyela umva kwisoftware yokukhowudi kwihardware efanayo - ubunzima be CPU obuphezulu, isixhobo esishushu, kunye neeframes ezikhuphekayo kwi-4K material. Kwisixhobo esimiselweyo, MP4 yindawo ekhuselekileyo yokugcinwa ehlala kuyo.

Ingaba i DivX iquka isiqulathi seefayili okanye i-codec, kwaye ngaba itshintsha into endiyifumanayo kwakhona?

Itshintsha into elindelekeyo kwifayile yemveliso. Icala elinye loguqulelo libiza ukukhowuda kunokuba ujikeleziso, ngoko oko kubuyela umva kukujikelezo lweebit ngaphakathi komgquba olungeleyo - ngokuqhelekileyo MP4 okanye MKV. Ulwandiso lubonisa umgquba; i codec yiyo eyaziyo ubungakanani befayile kwaye apho izakudlalwa khona.

WebM ikwi-browser-first. Iinketho eziphambili ziquka "ukulungelelanisa isixhobo" esimiselweyo esikhetha i-DivX codec / isiqulathi seefayili esikhuselekileyo so target yakho.

Ithatha ixesha elingakanani ukutshintsha i-MP4 yevidiyo yeyure enye ibe yi DivX?

I-Same-codec re-mux ikwindawo efutshane-imizuzu engama-30 ukuya kwengama-60 yefayili yeyure enye. I-codec epheleleyo iqhuba ngokuthe ngqo kwi-0.3-0.7x yobude bomthombo kwi-GPU yethu, ngoko ke i-1-hour MP4 → DivX igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.
