WMV ukuba MPG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-WMV ibe yi-MPG ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho ye WMV kwaye umguquli uqhube i-CRF-esekelwe kwi-encoding ephindayo ebhekisa kwi-visually-lossless MPG imveliso (i-CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne MPG isiqulathi-zifayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 yee-pipelines ezintsha. I-WMV ihambisa i-Microsoft VC-1 okanye i-WMV3 yevidiyo ngesandi se-WMA — ii-codecs azikho nto ngaphandle kweWindows ikhupha ikhowudi ngokusemthethweni. Okuqulethwe yi-MPEG-1 okanye i-MPEG-2 ividiyo ene-MP2 umsindo; ukudibanisa nokwakhiwa kwe-GOP kufana ne-.mpeg ifayili.

Ingaba i MPG igcina ngaphezulu kwengoma enye yesandi?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe WMV. MPG iphatha yonke imijelo yesandi njengento ephambili, ngoko udidi lwesivakalisi sokuqala, i-dub kunye nomlawuli wengxelo ingaphila kwifayile enye nomdlali otshintshela phakathi kwabo kwisicelo. MPG yi DVD yoshicilelo lwesoftware yolubanzi, i-camcorders edala kunye nezixhobo zokusasaza ukutya ziyazi, ngoko ihlala isetyenziswa kwezi ntambo.

Kutheni le nto ifayili yam WMV ayiphumelelanga ukutshintshela kwi MPG?

Iifayile ze WMV zifihliweyo kwinqanaba le bitstream yindawo yokurhweba okanye isoftware ekhupha ifayile, kwaye umjelo ofihliweyo awunakucodwe sisi okanye ngantoni na ngaphandle kwesitshixo selayisensi. Iifayile ozirekhode, ozirhwebe ngaphandle okanye ozikhuphele ezantsi azikhuselwanga ziguqula ngokuqhelekileyo; ukuthengiswa kwelayisensi akuyi kwenza njalo, kwaye akukho mguquli uthembekileyo okwaziyo ukuthembisa okuthile. WMV isebenza kakuhle iphele elahlekile: macOS, iOS, Android kunye ne-browser nganye kufuneka i-decoders yeqela lesithathu, kwaye ezinye iifayile ze-WMV zithwala i-DRM engatshintshi nantoni na.

Ingaba kukho incopho eguqula phakathi kwefomati ezimbini ezidala njenge WMV ne MPG?

Ukuba nje inxalenye ekhethekileyo yezixhobo ifuna injongo. Iifomati zombini zivela kwixesha elifanayo elingaphambili le-H.264, ngoko akukho kuguqulelo luthenga ukusetyenziswa kakuhle, umgangatho okanye uqinisekiso lwexesha elizayo - luthenga ukulungelelaniswa nesixhobo esithile. Ukuba injongo kukugcina imifanekiso esetyenziswa ixesha elide, guqula kwicontainer yangoku endaweni ye-sideways. MPG ifumana yonke i MPEG-2 imida - i-bitrate enzima, uthungelwano, akukho sihloko esicocekileyo - kunye nokungaqhelekanga kweendawo ezimbini zokukhupha ifomati enye.

Yeyiphi i-codec yevidiyo esetyenziswa yi-MPG?

Ixhomekeke kwi MPG isiqulathi seefayili. I-MP4 imiselwe ukuba ibe yi-H.264 ukuze ixhase ukudlala okubanzi phakathi kweefowuni, ii-browser, kunye ne-Smart TVs. I-MKV imiselwe ukuba ibe yi-H.265 / HEVC ukuze ilinganise nengxenye yobungakanani befayili kwinqanaba elifanayo lomgangatho. I-WebM imiselwe ukuba ibe yi-VP9. Iinketho eziphambili zibonisa ukhetho olucacileyo lwe-codec ukuba ufuna ukucima. I-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo.

Ingaba umculo wam wesandi uya kuqhubeka uguquka ukusuka kwi WMV ukuya kwi MPG?

Ewe. Xa WMV ne MPG zibelana nge-codec yesandi (umzekelo, zombini zithabatha i-AAC), isandi siphinda sixutywe ngaphandle kokubuyisela ukukhowuda - i-bit-identical. Xa ii-codecs zihlukile, isandi siguqulwa kwi-AAC / Opus / Vorbis kuxhomekeke ekubeni i-MPG ixhasa ntoni. I-audio enezithotho ezininzi (iingxelo, iilwimi ezitshintshiweyo) igcinwa.

Ndingagcina i-framerate yokuqala xa ndiguqula i-WMV ibe yi-MPG?

Ngokungagqibekanga ewe — i-24fps WMV ihlala i-24fps kwi-MPG; i-60fps WMV ihlala i-60fps. Ukuba ufuna ukuguqula umyinge (umzekelo, i-interlaced 29.97 → i-progressive 30, okanye i-60 → 30 yemida yokukhuphela), ukhetho lwe-framerate luphatha 3:2 ukutsala ezantsi, ukususa uthungelwano, kunye nokuqhekeka kwe-frame kwindlela efanayo yokufihla.

Ubungakanani befayili butshintsha njani ukusuka kwi WMV ukuya kwi MPG?

I-codec efanayo yokuphinda-phinda (WMV H.264 → MPG H.264 itshintsha kuphela isiqulathi seefayili): ubungakanani obufanayo. Utshintsho lwe-codec lunokutshintsha ngokumangalisayo: H.264 → H.265 luya kuquka ifayili kwinqanaba elifanayo lomgangatho wokubona; VP9 imalunga nokuthelekiswa; AV1 icima enye i-20-30% kodwa ihamba phantsi ukukopela.

Ingaba ifayili MPG iyadlala kwi-iPhone, Android, kunye neSmart TVs?

MP4 / H.264 idlala ngokusemthethweni kwisixhobo ngasinye esitsha. MOV / H.264 idlala kwizixhobo ze-Apple kunye neTV ezininzi kodwa hayi rhoqo kwi-Android edala. MKV ifuna i-VLC kwi-iOS. WebM ikwi-browser-first. Iinketho eziphambili ziquka "ukulungelelanisa isixhobo" esimiselweyo esikhetha i-MPG codec / isiqulathi esikhuselekileyo senjongo yakho.

Ithatha ixesha elingakanani ukutshintsha i-WMV yevidiyo yeyure enye ibe yi-MPG?

I-Same-codec re-mux ikwindawo efutshane-imizuzu engama-30 ukuya kwengama-60 yefayili yeyure enye. I-codec epheleleyo ephinda-ikhowudi iqhuba malunga nexesha lomthombo we-0.3-0.7x kwi-GPU yethu, ngoko ke i-1-iyure WMV → MPG igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.

Yintoni ubukhulu bomfanekiso oxhaswayo kwi WMV ukuya kwi MPG?

Ukuza kuthi ga kwi-8K (7680×4320) kwi-premium plans. Ukuguqulwa simahla kugqityiwe kwi-4K (3840×2160) ngumda wobungakanani befayili nganye. I-HDR metadata (HDR10, HDR10+, Dolby Vision xa ikhona) iqhutywa apho zombini i WMV ne MPG iinqanawa zixhasa khona.

Ingaba i-WMV yevidiyo yam ifihlakeleyo ngexesha liguqulwa libe li MPG?

Ewe. Iifayili zevidiyo ezilayishwe phezulu ziqhubekekiswa kubasebenzi abakhethekileyo, azisoloko zijongwa ngumntu, azisoloko zidweliswe kwisikhombisi, kwaye zicinywa kwimizuzu embalwa emva kokuphela. Ifestile yokugcina ibhalwe kwi /privacy/ kwaye asipapashi naziphi na iziqu zesifundo ezivela kubasebenzisi abalayishwe phezulu.

WMV

I-WMV (iVidiyo yeWindows Media) yifomati yocinezelo yevidiyo ephuhliswe nguMicrosoft. Ngokuqhelekileyo isetyenziselwa ukusasaza kunye neenkonzo zevidiyo ze-intanethi.
