MPG → WebM

Ichaitika kana iwe uchisaisa deinterlace, uye MPG zvemukati zvinonzi zvinokanganisa zvakanyanya nekuti fomati inosvika kubva kubroadcast uye DVD era. Interlaced frames kuchengetedza maviri epakati-hurefu maindasitiri akatora makumi maviri nemana esecond apart; pafoni kana monitor yeprogressive-scan iyo inoverenga sehomwe yekucheka pane chero chinhu chinofamba. Shandisa sarudzo yedeinterlace uye encoder inogadzira maindasitiri muzvikamu zvese zveprogressive frames mushure mekunyora WebM. MPG ndiyo imwe MPEG program stream se.mpeg — the three-letter extension is a DOS-era truncation, not a different format.

Yeah. MPG haina kushandiswa kweiyo soft-subtitle track, saka subtitle ye MPG zvikamu zvaifanira kusvibiswa mufananidzo kana kuendeswa seyakasiyana sidecar faira. WebM inotakura subtitle sezvavanosarudza, saka mushure mekushandurwa unogona kubatanidza SRT track iyo muverengi anogona kuvhura, kudzima kana kushandura.

Hapana kuvimbika. MPG inochengeta akawanda audio mapurojekiti sekutanga-class tracks, asi WebM kutamba rutsigiro mushure mekutanga track haina kuenderana, saka vazhinji vatambi vacharatidza chete mumwe. Choose the track you actually want before converting; the others are better extracted to their own files than left in a container that hides them. MPG ndiyo kusvikira DVD authoring software, vanopfuura camcorders uye kutumira ingestion zvinhu kubvuma, saka inogara zvakanakira kune avo pipelines. WebM isiri nyore kuisa chero kupi kunze kwebrowser – vanyori vemavhidhiyo, mafoni ane mavhidhiyo ekunze uye Smart TVs vanoisiya pachena.

A MPG yakaiswa muwebhu peji inoratidzwa neakavharwa mutambi kana kumanikidza kurodha pasi, nekuti mabrowser haasi kutumira chero decoder. WebM anotamba munzira kuburikidza neiyo yakasarudzika HTML5 video element pasina plugin uye pasina kunze kweapplication. WebM inotamba muwebhu browser yese yemazuva ano pasina plugin, pasina mari yechikwereti uye pasina patent exposure, izvo zvinoita kuti ive default yewebhu-yakaiswa video.

Yese chinhu iwe uchida kuchengeta, yeah. MPG inobva kune yekutanga rudzi rwevideo tooling uye software iyo inoverenga inoramba ichidzoka kubva kumafoni, mabrowser uye maoperating systems. Kufambisa mavhidhiyo ku WebM ikozvino, kunyangwe paine decoder yakachena, ndiyo kusiyana pakati pearchive iwe yaunogona kuvhura mumakore gumi nerimwe uye imwe iwe yausingagone. MPG anotora pazuva MPEG-2 kurambidzwa — heavy bitrate, interlacing, hapana soft subtitles — pamwe nekushaikwa kwezviviri kusvikira imwe format.

Zvinoenderana neWebM chigadzirwa. MP4 inomira paH.264 yekuwedzera kutamba kutsigira pakati pefoni, mabhurawuza, uye Smart TVs. MKV inomira paH.265 / HEVC yekuwedzera kutamba kutsigira pakati pefoni, mabhurawuza, uye Smart TVs. MKV inomira paH.265 / HEVC yekuwedzera kutamba kutsigira pakati pefoni, mabhurawuza, uye Smart TVs. MKV inomira paH.265 / HEVC yekuwedzera kutamba kutsigira pakati pefoni, mabhurawuza, uye Smart TVs. MKV inomira paH.265 / HEVC yekuwedzera kutamba kutsigira pakati pefoni, mabhurawuza, uye Smart TVs. MKV inomira paH.265 / HEVC yekuwedzera kutamba kutsigira pakati pefoni, mabhurawuza, uye Smart TVs. WebM isiri-yakajairika subset yeMatroska iyo Google yakaburitsa muna 2010 kuti iite HTML5 video seyemahara yekuchengetera.

Yeah. Kana MPG ne WebM vachishandisa imwe codec (semuenzaniso, vaviri vanoshandisa AAC), mitauro miviri ichashandiswa pamwe chete pasina kushandura. Kana codecs isiri yakafanana, mitauro miviri ichashandurwa kuita AAC / Opus / Vorbis zvichienderana neWebM. Mitauro miviri (yekutaura, mitauro mitsva) ichachengetwa.

Ne default yes — a 24fps MPG stays 24fps in WebM; a 60fps MPG stays 60fps. If you need to change rate (e. g. interlaced 29.97 → progressive 30, or 60 → 30 for upload limits), the framerate option handles 3: 2 pulldown, deinterlacing, and frame-blending in the same encode pass.

Same-codec re-mux (MPG H.264 → WebM H.264 chete kuchinja chigaro): zvakafanana saizi. Codec kuchinja anogona kuchinja zvakakomba: H.264 → H.265 zvinonyanya kuvharira faira pamwechete visual quality; VP9 iri zvakafanana; AV1 kubvisa 20-30% asi inononoka kushandura.

MP4 / H.264 inotamba zvakananga pazvose zvinodiwa zvinodiwa. MOV / H.264 inotamba paApple zvigadzirwa uye mamwe maTV asi kwete pazvinodarika Android. MKV inodiwa VLC paIOS. WebM ibrowser-kutanga. Yakakwira sarudzo dzinosanganisira "device compatibility" preset iyo inotora iyo yakanakisisa WebM codec / container yechinangwa chako.

Same-codec re-mux ndeyekukurumidza - 30 kusvika 60 masekondi e1-hour file. Full codec re-encode inofamba pa0.3-0.7x source duration paGPU pipeline yedu, saka 1-hour MPG → WebM inopera mu18-40 maminitsi zvichienderana ne resolution uye target codec.
