MOV kuya 3GP Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-MOV ibe yi-3GP ngaphandle kokubuyisela umbhalo ongezansi wevidiyo?

Uma ama-MOV ne-3GP amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-3GP ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB MOV ku-3GP ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. I-MOV ivame ukuthwala i-H.264 noma i-HEVC yokudlulisa, noma i-ProRes uma iyi-editor master, kanye ne-AAC noma umsindo we-PCM ongacindezelwa. 3GP igcina H.263 noma MPEG-4 Ingxenye 2 ividiyo nge AMR narrowband ukukhuluma umsindo, zonke tuned for minimal bitrate hhayi quality.

Ingabe MOV ingaguqulwa ibe 3GP ngaphandle kokuphinde ubhale kabusha ividiyo?

Yebo, futhi yindlela esheshayo. MOV ne 3GP zihlanganisa isakhiwo sebhokisi esifanayo esingaphansi, ngakho ividiyo nesandi sokushayela zikopiwe nge-byte-by-byte futhi isiqoqi sokushayela kuphela sibhale kabusha. Akukho okuqokwa futhi akukho okucindezelwa, ngakho ihele lezici ezide liqedwa ngaphansi kwemizuzu endaweni yehora elilodwa, nekhwalithi yesabelo esifanayo nesomthombo. MOV Apple's QuickTime isitsha, ethunyelwe ngo-1991 futhi akazange ashintshe ifomu iPhone, iPad noma Final Cut Pro timeline ubhala ngokuzenzakalela. I-3GP iyibhokisi le-3GPP elijwayelekile lefoni ephathekayo, lapho ividiyo idinga ukuhambisana ne-176x144 screen ne-2G data plan.

Yini ezoba nezinhlamvu zesihloko esingezansi kuhele lwami MOV?

Ngakhoni ukuhlala bekhethwa, ngoba 3GP ayikho i-soft-subtitle stream egcina isihloko. Kunezindlela ezimbili zokuzikhipha: ukufaka kuvidiyo ngesikhathi sokuguqulwa, okuzozenza zihlala zihlala futhi zingashintshwa, noma ukuthumela ngaphandle njenge.srt ehlukile ecaleni le 3GP ukuze umdlali alayishe. Umguquli utshela ukuthi yini eyayenza ngaphandle kokushiya isihloko ngokucophelela. I-3GP iphele ngezinhlamvu eziphansi kanye nesandi sokukhuluma esisezingeni eliphansi; ukuphakama kwayo ngeke kubuyisele imingwane engazange ithathwe.

I MOV yami inezinhlamvu zomsindo eziningi — zingaba zonke zihlala ngaphakathi kwe 3GP?

Akunakuthembeka. MOV igcina imisindo eminingi njengezingoma zohlobo lokuqala, kodwa 3GP uxhaso lokudlala ngaphezu kwengoma yokuqala akulingani, ngakho abadlali abaningi bazoveza kuphela eyodwa. Khetha ingoma oyifunayo ngaphambi kokuguqula; abanye bakhishwa kahle kumafayela abo ngaphezu kokushiya emgodini ofihlayo. MOV yifomethi abashicileli abaqeqeshiwe bacela, ngoba ihlala iphinda i-round-trips nge Final Cut Pro, Premiere ne DaVinci Resolve ngaphandle kokulahlekelwa kohlobo.

Yini ekwenzeke ku-5.1 surround audio uma uguqula MOV ku-3GP?

Kuxutshwe phansi ku-stereo, ngoba 3GP ayikho indlela ethembekile ye-multichannel. Ukuvala ngezansi kusetshenziswa izilinganiso ezijwayelekile ze-ITU ukuze ukuxhumana engxenyeni ye-channel ihlale icacile futhi izimo zifike ezingeni eliphansi kune-elingafihli. Noma yini esekelwe ekubekeni kwe-channel ehlukile idlule ngemuva kwalokho.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa MOV kuya ku 3GP?

Yebo — wonke umculo ohambayo ku MOV (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku 3GP lapho isiqoqi esizosiza umsindo ohambayo oningi. MKV ne MOV ziphatha umculo ohambayo ongenasiphelo; MP4 isekela abaningi kodwa abanye abadlali behardware babona umculo 1 kuphela; WebM iphele ku-Opus / Vorbis umculo owodwa.

Ingabe amabhayisikobho esihloko esingezansi agcinwa uma kuguqulwa MOV kuya ku 3GP?

Izihloko ezincane ezilula (izihloko ezikhethiwe) zihlala lapho 3GP zingazithwala: MKV igcina i-SRT, ASS, SSA, PGS, VobSub ngokusemthethweni; MP4 igcina kuphela i-mov_text (ifomethi ephukile). Ukushintsha MKV nge-ASS styled subs ku-MP4 kuzozikhuphula zibe yi-mov_text noma zizicwebezele. Izihloko ezinzima (zicwebezelelwe kwividiyo) zithwale ngaphandle kokungabaza.

Ingabe MOV kuya ku 3GP igcina iziphawuli zesiga-nyezi / ukuzula kwe-DVD-style?

Isigaba se-metadata sidlulisa phakathi kuka MOV no 3GP lapho izihlungi zombili zixhasa isiqephu se-atomi (MKV, MP4, MOV). I-WebM igcina iziqephu kwi-Matroska-compatible block, ngakho-ke i-MKV <-> isigaba se-WebM sihamba ngokuhlanzekile. I-AVI ayinasiqephu esicacisiwe, ngakho-ke ukushintsha i-AVI ibe yi-3GP kwenza ifayela elingahlukanisiwe ngaphandle kokuthi uhlanganise iziphawuli ngesandla.

Yini mayelana nezifakiwe ze-MKV (izifomethi, isigqoko somsebenzi) uma usuka ku MOV usuka ku 3GP?

MKV yindawo yokugcina eyinhloko kuphela egcina amafayela axhunywe ngokuzenzakalela (izifomethi ze-TTF ze-ASS subs, isithombe sokuzivikela se-JPG, izingeniso ze-PDF eziguqulwe nge-fan). Ukusuka ku-MOV kuya ku-3GP ushiya lezi zifomethi lapho i-3GP ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-MOV njenge-backup uma uhlala ubheke izifomethi ezixhunywe.

Yini i-codec esetshenziswa yi-3GP ngokuzenzakalela?

I-codec ejwayelekile ikhethiwe ukufana ne 3GP isitoreji ngokuzithandela: MKV ikhetha i-H.265 (HEVC) ukucindezela okuhle; MP4 ikhetha i-H.264 ukuxhasa isisetshenziswa esibanzi; WebM ikhetha i-VP9; AVI isebenzisa i-MPEG-4 ASP (DivX/Xvid lineage). Nciphisa nge-codec ethuthukisiwe engezansi — AV1 itholakala ku-MKV / WebM lapho ufuna khona ukucindezela okuphezulu futhi ungalindela ukucindezela. Amafayela we-3GP ancane futhi aguqula ikhodi ku-hardware encane kakhulu engingacabanga ngayo, ngakho-ke amafoni akhethekile nama-handset aphansi-end ahlala erekhoda.

Ingabe i-HDR (HDR10, Dolby Vision) ihlala isikhathi eside MOV kuya ku-3GP?

I-HDR metadata ehlala njalo (i-HDR10 mastering display values, max content light level) ihamba phambili ku-3GP uma izihlungi zombili ne-codec ekhethiwe ziyixhasa (HEVC, AV1 ku-MKV / MP4). I-Dolby Vision inamandla kakhulu — i-DV profile 5 / 7 / 8.1 ku-MOV ihlala kuphela ku-MKV nge-HEVC; ukushintsha ku-3GP isihlungi esingathwala i-DV layer ihamba phambili ku-HDR10.

Ingabe i MOV kuya ku 3GP igcina ifreyimu eshintshayo (VFR)?

MKV ne WebM zirekhoda ama-timestamps we-frame ngayinye futhi ziphatha i-VFR ngokusemthethweni, ngakho-ke i-MOV VFR ihlala i 3GP yalezi fomu ngaphandle kokuphindeka kokuhlolwa. I-MP4 igcina ama-timestamps futhi kodwa abanye abadlali bakholelwa ukuthi i-CFR; umguquli ubonisa "u forza CFR" ukushintsha okuphinda ukuhlolwa kwe-VFR MOV kuya ku-24 / 30 / 60 fps 3GP ngezinhloso ezinomthelela.

MOV

I-MOV iyifomethi ye-QuickTime ye-Apple, esekela ividiyo nomsindo wekhwalithi ephezulu wokuhlela kobungcweti.

3GP

I-3GP iyifomethi yesitsha semultimedia eyenzelwe omakhalekhukhwini be-3G. Ingagcina idatha yomsindo nevidiyo futhi ivamise ukusetshenziselwa ukudlalwa kwevidiyo yeselula.
