Kodi ndingasinthire bwanji MPG kupita ku MPEG popanda kuwononga mtundu wa kanema?

Ikani fayilo yanu ya MPG ndipo wosinthira amayendetsa CRF-based re-encode yoyang'anira kutulutsa kwa MPEG (CRF 18 mosalekeza, matanthauzo ochepa = fayilo yayikulu / yapamwamba). Codec imasankhidwa kuti igwirizane ndi MPEG kontena - H.264 kwa MP4 yokhala ndi kukula kwakukulu, H.265 kwa MKV yokhala ndi kukula kwakukulu, VP9 kwa WebM, AV1 kwa ma pipelines atsopano. Zina mwa zinthuzi ndi MPEG-1 kapena MPEG-2 kanema ndi MP2 audio; muxing ndi GOP chilengedwe ndi ofanana ndi.mpeg fayilo. Video ndi MPEG-1 kapena MPEG-2 ndi MP2 kapena AC-3 Audio, multiplexed mu mtsinje wopangidwa kuti ayambe kusinthidwa ndi fixed-function hardware.

Kodi MPG ingasinthidwe ku MPEG popanda kubwezeretsa kanema?

Ndikugwirizana ndi ma DVD a 4K, ndipo ndi njira yofulumira. MPG ndi MPEG amagawana bokosi lofanana lokhala ndi bokosi, kotero mavidiyo ndi ma audio streams amakopedwa m'ma byte-by-byte ndipo kokha kokhala ndi chotengera chokhala ndi chosindikizira. Sichidzasinthidwa ndipo sichidzasinthidwa, chifukwa chake fayilo ya feature-length imatha m'maola angapo m'malo mwa ola limodzi, ndi mtundu wa output womwe uli ndi mtundu wofanana ndi wopanga. MPG ndi chimodzimodzi MPEG pulogalamu mtsinje monga.mpeg - atatu-alemba kuwonjezeka ndi DOS-era kugwa, si mtundu wina. MPEG pano kumatanthauza MPEG-1 kapena MPEG-2 pulogalamu mtsinje, mtundu standardized kwa Video CD ndi kenako kwa DVD ndi kufalitsa TV.

Kodi pali chinthu chosintha pakati pa mafomu awiri oyambirira monga MPG ndi MPEG?

Ngati chinthu chokhacho cha zida chikufunikira kukwaniritsa zolingazo. Mafomu awiriwa amachokera kunthawi yomweyo ya H.264, kotero palibe kusintha komwe kumagula chitetezo, kudalirika kapena kutsimikizika kwatsogolo - kumagula kugwirizana ndi chipangizo chimodzi chokha. Ngati cholinga ndicho kuteteza zithunzi zogwiritsa ntchito nthawi yayitali, kusintha kwa kontena latsopano, osati kumbuyo. MPG amalandira zonse MPEG-2 kuletsa - heavy bitrate, interlacing, palibe soft subtitle - kuphatikizapo kusokonezeka kwa awiri zowonjezera kwa mtundu wina. MPEG-2 amafuna pafupifupi 4 mpaka 6 nthawi ya bitrate ya H.264 kwa chithunzi chimodzi, ndipo zinthu zake nthawi zambiri zimaphatikizidwa, zomwe zimawoneka zosapanga dzimbiri pazowonera zamakono.

Ndiko. Ngati MPG ndi MPEG amagwiritsa ntchito codec ya audio (mwachitsanzo, onse amagwiritsa ntchito AAC), audio imasinthidwanso popanda kusinthidwanso - bit-identical. Ngati codecs ndi osiyana, audio imasinthidwanso kukhala AAC / Opus / Vorbis malinga ndi zomwe MPEG zimathandizira. Audio yokhala ndi ma track ambiri (mawu ofotokoza, mabungwe osiyanasiyana) imasungidwa.

Kodi ndingapeze bwanji mitengo yazithunzi yoyamba pamene ndisintha MPG kupita ku MPEG?

Ngati mukufuna kusintha kuchuluka (mwachitsanzo, kulumikizana 29.97 → kupitilira 30, kapena 60 → 30 kwa kutsitsa), kusankha kwa framerate kumatha kuwongolera 3: 2 kutsitsa, kuchotsa, ndi kuphatikizira ma frame mu gawo limodzi lokha la encoding.

Kodi kukula kwa fayilo idzasintha bwanji kuchokera ku MPG kupita ku MPEG?

Kodikodi yofananayo imasintha (MPG H.264 → MPEG H.264 yomwe isintha kontena): kukula kwake kuli pafupifupi chimodzimodzi. Kusintha kwa codec kungayambitse kusinthika kwambiri: H.264 → H.265 nthawi zambiri kumadula fayiloyo panthawi yomweyo; VP9 ndi yofanana; AV1 imadula 20-30% koma ndi yocheperako.

Kodi fayilo ya MPEG idzasewera pa iPhone, Android, ndi Smart TVs?

MKV iyenera VLC pa iOS. WebM ndi msakatuli woyamba. Zosankha zopitilira muyeso zimaphatikizapo "kugwirizana kwa chipangizo" choyamba chomwe chimasankha chotetezeka kwambiri MPEG codec / chidebe chazofunikira zanu. MPEG pulogalamu ma streams ndi decoded ndi literally aliyense DVD wosewera mpira, set-top bokosi ndi kufalitsa mzere kale anamanga, ndipo iwo kulola bit zoipa graciously.

Kodi ndi nthawi yayitali bwanji kusinthira kanema wa 1-hour MPG kuti MPEG?
