Tsitsani kuyimitsa kwanu: ma Codecs, Containers, Wrappers & Makanema Akanema
aliyense digito filimu kapena kanema ndi kuphatikiza ndi ziro. Mutha kusewera mozungulira ndi datayo kwambiri kuti mupange fayilo yayikulu kukhala yaying'ono popanda kusiyana kowonekera.
Pali matekinoloje osiyanasiyana, mayina amalonda ndi miyezo. Mwamwayi, pali zingapo zokhazikitsira zomwe zimapangitsa kusankha kukhala kosavuta, ndipo posachedwa Adobe Media Encoder ichotsa ntchito yochulukirapo m'manja mwanu.
M'nkhaniyi tikufotokoza zoyambira mophweka momwe tingathere ndipo mwina padzakhala kutsata kwaukadaulo pamutuwu.
Mu positi iyi tikambirana:
Kupanikiza
Chifukwa vidiyo yosakanizidwa imagwiritsa ntchito deta yochuluka, zambiri zimakhala zosavuta kuti kufalitsa kukhale kosavuta. Kukwera kwapanikiza, fayiloyo imakhala yaying'ono.
Mudzataya zambiri zazithunzi. Izi nthawi zambiri zimaphatikizapo kupsinjika kwamphamvu, ndi kutayika kwa khalidwe. Kupanikizika kosatha sagwiritsidwa ntchito kawirikawiri pogawa mavidiyo, pokhapokha panthawi yopanga.
Codecs
Iyi ndi njira yochepetsera deta, mwachitsanzo, compression algorithm. Kusiyana kumapangidwa pakati pa audio ndi kanema. Ubwino wa aligorivimu, kuchepa kwa khalidwe.
Zimaphatikizapo kuchuluka kwa purosesa kuti "mutulutse" chithunzicho ndikumvekanso.
Mitundu yotchuka: Xvid Divx MP4 H264
Chidebe / Wrapper
The chophimba amawonjezera zambiri ku kanema monga metadata, subtitles ndi indexes kwa DVD kapena Blu-Ray zimbale.
Si mbali ya fano kapena phokoso, ndi mtundu wa pepala kuzungulira maswiti. Mwa njira, zilipo codecs omwe ali ndi dzina lofanana ndi chidebe monga: MPEG MPG WMV
Kuyamba ndi zolemba zanu zoyimitsa nkhani
Lembetsani ku kalata yathu yamakalata ndikutsitsa kwaulere ndi zolemba zitatu. Yambani ndikupangitsa nkhani zanu kukhala zamoyo!
Tidzangogwiritsa ntchito imelo yanu kutsamba lathu ndikulemekeza lanu zachinsinsi
M'makampani opanga mafilimu, MXF (kujambula kamera) ndi MOV (ProRes kujambula / kusintha) amagwiritsidwa ntchito kwambiri wrappers. M'malo ochezera a pa TV komanso pa intaneti, MP4 ndiye mtundu wodziwika bwino wa chidebe.
Mawu awa mwa iwo okha sanena zambiri za khalidwe. Izi zimatengera mbiri yomwe ikugwiritsidwa ntchito. Mwachitsanzo, muyenera kulabadira kuchuluka kwa psinjika. Chigamulo chingakhalenso chosiyana.
Fayilo ya HD 720p yokhala ndi kupsinjidwa pang'ono nthawi zina imatha kukhala yabwino kuposa fayilo ya Full HD 1080p yokhala ndi kuponderezedwa kwakukulu.
Pakupanga, gwiritsani ntchito mawonekedwe apamwamba kwambiri kwautali momwe mungathere ndikudziwitsani komwe mukupita ndi mtundu wake panthawi yogawa.
Makanema opondereza a kuyimitsa kuyenda
Zokonda izi ndizo maziko. Inde zimadalira gwero la zinthu. Palibe zomveka kubisa 20Mbps kapena ProRes ngati gwero linali 12Mbps yokha.

Kumbukirani kuti makanema amakanema ngati YouTube amasinthiranso makanema omwe mumawayika pamawonekedwe osiyanasiyana ndikusintha malinga ndi zomwe zidakonzedweratu.
Moni, ndine Kim, mayi komanso wokonda kuyimitsa zoyenda komanso wodziwa zambiri pakupanga media komanso kakulidwe ka intaneti. Ndili ndi chikhumbo chachikulu chojambula ndi makanema ojambula, ndipo tsopano ndikudumphira molunjika kudziko loyimitsa. Ndi blog yanga, ndikugawana zomwe ndaphunzira ndi inu anyamata.
