Ndinogona sei kudzokorora kurodha MPG kuenda ku MPEG pasina kushaya mhando yevhidhiyo?

Upload yako MPG faira uye mushanduri unoenderera neCRF-based re-encode inotarisana nevisually-lossless MPEG output (CRF 18 sezvakarongwa, zvishoma zviyero = hombe faira / yepamusoro mhando). Codec inosarudza kusangana neMPEG container - H.264 yeyakakwira-compat MP4, H.265 yemhando-inodhura MKV, VP9 yeWebM, AV1 yezvinotsva mapurojekiti. Zvinhu zvinoreva MPEG-1 kana MPEG-2 video neMP2 audio; muxing uye GOP kugadzira zvakafanana.mpeg faira. Video i MPEG-1 kana MPEG-2 neMP2 kana AC-3 audio, multiplexed mumvura yakagadzirwa kuti decoded ne fixed-function hardware.

Chii chinonzi MPG? Chii chinonzi MPEG?

Kana chinangwa chiri kuchengetedza mavhidhiyo anogoneswa kwenguva yakareba, shandura kune chigadzirwa chenguva dzose, kwete kuchinjanisa. MPG anotora pazuva MPEG-2 kurambidzwa — heavy bitrate, interlacing, hapana soft subtitles — pamwe nekushaikwa kwezviviri kusvikira imwe format. MPEG-2 inodiwa zvakakwana 4-6 nguva bitrate yeH.264 yeimwe vhidhiyo, uye zvinhu zvayo zvinonzi zvinongedzo, izvo zvinotaridzika zvakakombama pazvinoratidzwa.

Chinyorwa che MPEG chinotamba pa iPhone, Android, uye Smart TVs?

MP4 / H.264 inotamba zvakananga pane chero chishandiso chemazuva ano. MOV / H.264 inotamba paApple zvigadzirwa uye mamwe maTV asi kwete nguva dzose pakare Android. MKV inodiwa VLC paIOS. WebM ndeyebrowser-kutanga. Yakakwira sarudzo dzinosanganisira "device compatibility" preset iyo inotora iyo yakanyanya kuchengetedzeka MPEG codec / container yechinangwa chako. MPEG chirongwa mabwe anodecoded ne literally chero DVD mutambi, set-top box uye broadcast chain ever built, uye ivo kutonhora bit matambudziko graciously.

Ndeipi nguva yekushandura 1-hour MPG video kuenda ku MPEG?
