Igenamigambi ryiza ryohereza hanze kuri Premiere Pro

Sobanukirwa na Premiere Pro yohereza hanze

Adobe Premiere Pro itanga imiterere myinshi yo kohereza hanze, ariko guhitamo igikwiye biterwa numushinga wawe ugenewe. Imiterere isanzwe irimo H.264 / MP4 yo gukwirakwiza muri rusange, H.265 / HEVC kubintu 4K bisaba ubunini bwa dosiye ntoya, na ProRes kubikorwa byumwuga bisaba kwikuramo bike. Buri format ikora intego zitandukanye – H.264 itanga ubwuzuzanye buhebuje mubikoresho hamwe na platform, mugihe ProRes ikomeza ubuziranenge kubikorwa byanyuma. Mugihe uhisemo uburyo bwo kohereza hanze, tekereza neza ibyo utanga. Gukwirakwiza urubuga, H.264 hamwe na MP4 kontineri itanga uburinganire bwiza bwubunini nubunini bwa dosiye. Kubitangaza cyangwa gutanga umwuga, imiterere nka ProRes 422 cyangwa DNxHD itanga ubuziranenge busabwa ninzobere mu nganda. Gusobanukirwa itandukaniro bituma ibicuruzwa byawe byoherezwa mu mahanga byujuje ibya tekiniki mugihe ugumana ubuziranenge bwiza kubo ukurikirana.

• H.264 / MP4 kurubuga no gukwirakwiza muri rusange
• H.265 / HEVC kubintu 4K bifite ubunini bwa dosiye
• ProRes kubikorwa byumwuga nyuma yumusaruro
• DNxHD yo gutangaza-ubuziranenge butangwa

Guhitamo Codec hamwe nigenamiterere ryiza

Codec wahisemo igira ingaruka zikomeye mubunini bwa dosiye hamwe nubwiza bugaragara. H.264 ikomeza kuba inganda mubikorwa byinshi, itanga uburyo bwiza bwo guhunika no guhuza isi yose. Ku mishinga 4K, H.265 (HEVC) itanga compression nziza cyane, igabanya ingano ya dosiye kugera kuri 50% ugereranije na H.264 mugihe ikomeza ubuziranenge. Ariko, H.265 isaba imbaraga nyinshi zo gutunganya kandi irashobora kugira ibibazo byo guhuza nibikoresho bishaje. Igenamiterere ryiza muri buri codec yemerera guhuza neza urwego rwo kwikuramo. Guhindura Bitrate (VBR) kodegisi mubisanzwe itanga ibisubizo byiza kurenza Constrate Bitrate (CBR) mugutanga amakuru menshi mubice bigoye. Kuri H.264, intego ya bitrate ya 8-12 Mbps ikora neza kubintu 1080p, mugihe 4K mubisanzwe bisaba 20-35 Mbps. Igenamiterere riringaniza ingano ya dosiye hamwe nubwiza bugaragara, kwemeza ibikubiyemo bisa nkumwuga udakoze dosiye nini bitari ngombwa.

• Koresha kodegisi ya VBR kugirango ukwirakwize neza
• Intego 8-12 Mbps kubintu 1080p H.264
• Reba 20-35 Mbps kuri 4K yohereza hanze
• Gerageza H.265 kumishinga 4K isaba dosiye nto

Gukemura no Kuringaniza Igipimo

Guhuza ibyo wohereje hanze kumurongo wagenewe gutanga byerekana ubwiza mugihe ugabanya ingano ya dosiye. Kuri YouTube hamwe nu mbuga nyinshi, 1920×1080 ikomeza kuba ahantu heza kubintu rusange, nubwo 4K (3840×2160) ikunze kugaragara kubintu byiza cyane. Buri gihe wohereze mugihe cyagenwe cyateganijwe keretse niba ugabanutse cyane kubitekerezo bya bande. Kwiyongera mugihe cyo kohereza hanze bigomba kwirindwa kuko bitongeyeho amakuru nyayo kandi byongera ubunini bwa dosiye bitari ngombwa. Guhitamo igipimo cya frame biterwa nubwoko bwibirimo hamwe nababigenewe. 24fps itanga cinematike yibirimo kuvuga, mugihe 30fps itanga icyerekezo cyoroshye kubirimo amashusho rusange. Kubijyanye nimikino cyangwa siporo, 60fps itanga icyerekezo cyoroshye ariko ikubye kabiri ibisabwa byamakuru. Huza igipimo cyo kohereza ibicuruzwa hanze mugihe cyagenwe cyagenwe keretse niba ubishaka ukora ibintu bitinda-bigenda cyangwa bihuye nibisabwa byihariye.

Amajwi yohereza ibicuruzwa hanze no gutekereza

Igenamiterere ryamajwi rigira ingaruka nziza muburyo rusange bwo kohereza hanze, nyamara akenshi birengagizwa. Kubisabwa byinshi, codec ya AAC kuri 48kHz yicyitegererezo hamwe na 320 kbps bitrate itanga ubuziranenge buhebuje. Stereo (2-umuyoboro) isohoka ikora kubintu byinshi, nubwo 5.1 amajwi azengurutse arashobora gukenerwa mugutangaza cyangwa gutanga ikinamico. Buri gihe uhuze igipimo cyawe cyoherejwe cyoherejwe mugihe cyagenwe kugirango wirinde gutunganya amajwi bitari ngombwa. Witondere urwego rwamajwi mugihe cyohereza hanze – igamije urwego rwo hejuru -3dB kugirango wirinde gukuramo mugihe ukomeje amajwi ahagije. Kugirango utangaze amakuru, urashobora gukenera kubahiriza amajwi yihariye nka -23 LUFS kuri tereviziyo cyangwa -16 LUFS kubitambuka. Tekereza gukora amajwi atandukanye yoherejwe muburyo butandukanye bwo gutanga, kuko gukwirakwiza podcast bisaba igenamiterere ritandukanye no kohereza amashusho.

Ihuriro-ryihariye ryohereza ibicuruzwa hanze

Amahuriro atandukanye afite ibisabwa bya tekiniki kandi asabwa gushiraho uburyo bwiza bwo gukina. YouTube irasaba codec ya H.264 hamwe na scan igenda itera imbere, igipimo gisanzwe (24, 25, 30, 48, 50, 60 fps), hamwe na bitrate yihariye bitewe nicyemezo. Kubyoherejwe 1080p, YouTube itanga 8 Mbps kubisanzwe bisanzwe na 12 Mbps kubintu biri hejuru. Instagram isaba kare (1: 1) cyangwa ihagaritse (9:16) ibipimo byerekana uburyo bwiza bwo kureba kuri terefone igendanwa, hamwe nigihe ntarengwa cyigihe cyo kugaburira ibiryo hamwe ninkuru. Vimeo mubisanzwe yemerera bitrate kurenza YouTube, bigatuma ikwiranye no kwerekana akazi keza cyane kubakiriya. Igenamigambi ryabo risabwa ririmo bitrate yo hejuru – kugeza kuri 20 Mbps kubintu 1080p. Facebook hamwe nizindi mbuga nkoranyambaga akenshi zifite ibisabwa byihariye kuri autoplay, harimo amajwi atandukanye hamwe nibisobanuro. Gusobanukirwa nibisabwa byihariye byerekana neza ko ibikubiyemo byerekana neza kandi bikagera kubantu benshi bashoboka.

• YouTube: 8-12 Mbps kuri 1080p, codec ya H.264
• Instagram: Imiterere ya kare cyangwa ihagaritse yo gutezimbere mobile
• Vimeo: Bitrate yo hejuru iremewe, kugeza kuri 20 Mbps kuri 1080p
• Facebook: Reba ibisabwa autoplay nibisabwa

Gukora neza Kumurimo no gucunga dosiye

Ibikorwa byiza byohereza ibicuruzwa hanze bizigama igihe kandi byemeze ibisubizo bihamye mumishinga. Kurema no kuzigama ibicuruzwa byoherejwe mbere yuburyo busanzwe bwo gutanga kugirango ukureho igenamiterere risubiramo. Vuga ibyo wateguye mubisobanuro (urugero, “YouTube 1080p Standard” cyangwa “Isubiramo ry’abakiriya H.264”) hanyuma ubitondere ukurikije ibyiciro cyangwa ibyo umukiriya asabwa. Ubu buryo butunganijwe bugabanya amakosa kandi byihutisha uburyo bwo kohereza ibicuruzwa hanze. Reba ibikorwa byawe nyuma yo kohereza hanze mugihe uhitamo igenamiterere hamwe na dosiye. Niba ukeneye guhindura dosiye zoherejwe hanze muburyo butandukanye kubibuga bitandukanye, kugira ama sisitemu ya sisitemu yo kwita izina biba ngombwa. Ibikorwa bimwe byungukirwa no kohereza ibicuruzwa byiza murwego rwo hejuru ubanza, hanyuma ugakora verisiyo yihariye iva kuri shobuja. Ubu buryo butuma ibintu byose bitangwa mugihe hagumyeho ubuziranenge bushoboka murwego rwo gukwirakwiza.
