Yintoni inombolo nganye
Isantya samakhasi yimifanekiso emingaphi eboniswa ngemizuzwana enye. Ezine ozidibana nazo kakhulu:
Apho kuvela khona i-0.1%
23.976 = 24 × 1000/1001, kwaye 29.97 = 30 × 1000/1001. Loo 1000/1001 yintsalela yokongeza umbala kwi-NTSC: ukufaka umbala ngaphakathi ngaphantsi ngaphandle kokuphula abamkeli abamnyama nabaqabukayo, isantya samabala sehla ukusuka ku-60 Hz ukuya ku-59.94 Hz (60 × 1000/1001), kwaye isantya samakhasi sehla kunye naso.
Isiphumo: iimuvi ziboniswa ku-23.976 kwiindawo ze-NTSC endaweni ka-24. Umahluko ngu-0.1%, okanye imizuzwana engu-3.6 kwisixa seyure enye — kuphantse kungabonakali ngesiqu saso, kodwa musa ukuyidibanisa ne-4% engezantsi kwaye ungaqinisekisi ukuzidibanisa zombini kubalo olunye.
Apho kuvela khona i-4%
Iindawo ze-PAL zibonisa ku-25 fps. Iimuvi zishicilelwa ku-24 fps kwaye zidlalwa nje ku-25 — akukho khasi linyusiweyo okanye licinyiweyo, ngoko ukudlala kuqhuba ngokukhawuleza ngo-4% (25/24 ≈ 1.0417). Imuvi yemizuzwana engu-100 iqhuba imizuzwana engu-96 kwinguqulelo yayo ye-PAL.
Yiyo loo nto ungcambu lwe-progressive drift: i-subtitles ezenzelwe umthombo nevidiyo kwinguqulelo ye-PAL zihambelana ngokuchanekileyo ekuqaleni kwaye ziziimimitha ezine ngamakhredithi. Akukho tshintsho lwehlabathi lonke olungasindisa loo nto; kufuneka ilinganiswe ngomlinganiselo.
Uyiguqulela njani
Ukuguqulela kuthetha ukuphindaphinda ngomlinganiselo omnye osebenza kwiimuvi zonke:
Ukwazi ukuba unayiphi
Endaweni yokuqikelela umlinganiselo, fumana amaxesha amabini oqinisekileyo ngexesha lawo — ngokuqhelekileyo imigca yokuqala neyokugqibela yoncoko — kwaye uxelele isixhobo "lo mgca kufuneka ube ku-00:00:12 kwaye lowo ku-01:35:40"; yolula imuvi yonke ngokuthe ngqo phakathi kwaloo manqinda mabini. Obu ngubizo "lwamanqinda amabini", kwaye aludingi sibalo sesantya samakhasi kuwe.
Ukuqinisekisa isantya samakhasi ngokwakho, hlola isidlali sakho okanye isixhobo solwazi lwemidiya. Xa igama lefayile lifana no-`1080p.WEB` lingabonisi nkcazo yesantya samakhasi, ukubethelela kwamanqinda amabini yindlela ekhuselekileyo.
Izixhobo ezihambelanayo nezikhombandlela
Ukuguqula isantya samakhasi ngokwaso — Subtitle frame rate conversion; ulungiso lwesantya — Subtitle speed conversion; awuqinisekanga ukuba kungcoliseko lwehlabathi lonke okanye i-progressive drift — Subtitles drifting further out of sync.
