WMV ukuba MPG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho WMV kwaye umguquli uqhuba i-CRF-esekelwe kwakhona-ukukopela ukujolisa kwi-visually-lossless MPG imveliso (CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne MPG isiqulathi seefayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 ye-newer pipelines. 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 umsinga ofihliweyo awunakucodwe sisi okanye ngantoni na ngaphandle kwesitshixo selayisensi. Iifayile ozirekhode, ozirhwebe ngaphandle okanye ozikhuphele ezantsi 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 yemveliso?

Ixhomekeke kwi MPG isiqulathi seefayili. I-MP4 imiselwe ukuba i-H.264 ukuze ixhase ukudlala okubanzi phakathi kweefowuni, iibrowser, kunye neSmart TVs. I-MKV imiselwe ukuba i-H.265 / HEVC ukuze ijikeleze i-half of the file size at equivalent quality. I-WebM imiselwe ukuba i-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 WMV ukuya MPG?

Yes. When WMV and MPG share an audio codec (e.g. both carry AAC), audio is re-muxed with no re-encode — bit-identical. When the codecs differ, audio is transcoded to AAC / Opus / Vorbis depending on what the MPG container supports. Multi-track audio (commentary, alternate languages) is preserved.

Ndingagcina i-framerate yokuqala xa ndiguqula i-WMV iye kwi-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 yokukhuphela umda), ukhetho lobungakanani be-frame luphatha 3:2 ukutsala ezantsi, ukususa uthungelwano, kunye nokuqhekeka kwe-frame kwindlela efanayo yokukopela.

Ingaba ubungakanani befayili butshintsha njani ukusuka kwi WMV ukuya kwi MPG?

I-codec efanayo yoku-mux (WMV H.264 → MPG H.264 itshintsha kuphela isiqulathi seefayili): ubungakanani obufanayo. Utshintsho lwe-codec lunokutshintsha ngokumangalisayo: H.264 → H.265 luya kuquka ifayile kwinqanaba elifanayo lomgangatho obonakalayo; VP9 imalunga nokuthelekiswa; AV1 iquka 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 zeApple 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 seefayili esikhuselekileyo so target 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 iqhuba ngokuthe ngqo kwi-0.3-0.7x yobude bomthombo kwi-GPU yethu, ngoko ke i-1-hour WMV → MPG igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.

Yintoni ubukhulu bokubonisa obuxhaswa yi WMV ukuya kwi MPG?

Ukuya kwi-8K (7680×4320) kwi-premium plans. Ukuguqulwa simahla kugqityiwe kwi-4K (3840×2160) ngobukhulu befayili nganye. I-HDR metadata (HDR10, HDR10+, Dolby Vision xa ikhona) iqhutywa apho zombini WMV ne MPG iziqulathi zixhasa khona.

Ingaba i-WMV yevidiyo yam ifihlakeleyo ngexesha lokuguqulwa kwi-MPG?

Ewe. Iifayili zevidiyo ezilayishwe phezulu ziqhubekekiswa kubasebenzi ababekwe ngokuzimeleyo, aziboniswanga ngumntu, azikho kwisicwangciso, zicinywa ngaphakathi kwemizuzu yokuphela. Ifestile yokugcina ibhalwe kwi /privacy/ kwaye asipapashi naziphi na iziqu zemfundo ezisuka kubasebenzisi abalayishwe phezulu.
