MPG ku MPEG Mafunso Ofunsidwa Kawirikawiri Okhudza Kusintha kwa Anthu

Kodi ndingatani kuti ndibwezeretse MPG ku MPEG popanda kuwononga mtundu wa kanema?

Ikani fayilo yanu ya MPG ndipo wosintha amayendetsa CRF-based re-encode yoyang'anira kutulutsa kwa MPEG (CRF 18 mosalekeza, matanthauzo ochepa = fayilo yayikulu / yapamwamba). Codec imasankhidwa kuti igwirizane ndi MPEG - H.264 kwa MP4 yokhala ndi kutalika, H.265 kwa MKV yokhala ndi kukula, 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?

Ndikukhulupirira kuti ndinu oyenera, ndipo ndi njira yofulumira. MPG ndi MPEG amagawana chilengedwe chofanana cha box, choncho mavidiyo ndi ma audio streams amakopedwa m'ma byte-by-byte ndipo ma container wrapper okha amalembanso. Sichidzasinthidwa ndipo sichidzasinthidwa, choncho fayilo ya feature-length imatha m'maola angapo osati m'maola awiri, 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.

Kodi ndi codec iti ya video yomwe MPEG imagwiritsa ntchito?

Izi zimadalira bokosi la MPEG. MP4 imasinthidwa ku H.264 kuti ithandizire kusewera kwa mafoni, mawebusayiti ndi Smart TV. MKV imasinthidwa ku H.265 / HEVC kwa pafupifupi theka la kukula kwa fayilo pazomwe zimafanana. WebM imasinthidwa ku VP9. Zosankha zazikulu zimawonetsera kusankhidwa kwa codec ngati mukufuna kuchotsa.

Kodi nyimbo yanga ya audio idzapulumuka ku MPG kupita ku MPEG?

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

Kodi ndingapeze bwanji chiwonetsero chazithunzi chakale posintha MPG ku MPEG?

Mwa default yes - 24fps MPG imakhala 24fps mu MPEG; 60fps MPG imakhala 60fps. Ngati mukufuna kusintha mtengo (mwachitsanzo, interlaced 29.97 → progressive 30, kapena 60 → 30 kwa kutsitsa), mfundo ya framerate imayendetsa 3: 2 pulldown, deinterlacing, ndi frame-blending mu gawo limodzi lokha la encoding.

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

Same-codec re-mux (MPG H.264 → MPEG H.264 just changing container): nearly identical size. Codec change can swing dramatically: H.264 → H.265 typically halves the file at the same visual quality; VP9 is roughly comparable; AV1 cuts another 20-30% but is slower to encode.

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

MP4 / H.264 imasewera mwachilengedwe pazinthu zonse zamakono. MOV / H.264 imasewera pazinthu za Apple ndi ma TV ambiri koma si nthawi zonse pa Android oyambirira. MKV iyenera VLC pa iOS. WebM ndi browser-first. Zosankha zopitilira muyeso zimaphatikizapo "kugwirizana kwa chipangizo" choyamba chomwe chimasankha chotetezeka MPEG codec / chidebe chazolinga zanu. MPEG pulogalamu ma streams ndi decoded ndi literally aliyense DVD wosewera mpira, set-top bokosi ndi kufalitsa mzere kale anamanga, ndipo iwo kupewa bit zoipa graciously.

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

Kusinthanso kwa codec yomweyo ndi nthawi ya 30 mpaka 60 kwa fayilo ya 1-hour. Kodi yokhala ndi codec yokhala ndi codec imagwira ntchito panthawi ya 0.3-0.7x yokhala ndi GPU, kotero 1-hour MPG → MPEG imatha m'maola 18-40 malinga ndi resolution ndi codec yofunikira.

Kodi ndi chiyani chofunikira kwambiri chothandizira kwa MPG mpaka MPEG?

Kuyambira 8K (7680 × 4320) pazosankha za Premium. Zosintha zaulere zimatha ku 4K (3840 × 2160) pogwiritsa ntchito kukula kwa fayilo. HDR metadata (HDR10, HDR10 +, Dolby Vision pamenepo) imatha kuchitika pomwe ma containers a MPG ndi MPEG amathandizira.

Kodi kanema wanga MPG ndi wapadera posintha ku MPEG?

Yai. Uploaded kanema owona ndi kuchitidwa mu ogwira ntchito osiyana, nthawi zonse sakuona ndi munthu, nthawi zonse salemba, ndi kuchotsa m'maola angapo ya kumaliza. Kusunga zenera ndi zolemba pa /privacy/ ndi ife kufalitsa palibe maphunziro corpus kuchokera kutsitsa wosuta.

Kodi ndingagwiritse ntchito, kuchotsa kapena kuzungulira nthawi ya MPG mpaka MPEG yosinthira?

Sichingakhale panjira yomweyo - kugwiritsa ntchito / video-trim / kapena / video-cutter / kuti muchepetse koyamba, kenako yambitsani kusinthika kwa MPG → MPEG. Kusinthanitsa ndi kusintha kwa chaining ndi kosavuta kuposa kubwezeretsa komaliza kwa MPG kuti muchepetse zithunzi zosagwiritsa ntchito.
