MPG kuya MPEG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani i-MPG ku-MPEG ngaphandle kokulahlekelwa yikhwalithi yevidiyo?

Ukufaka ifayela lakho MPG futhi hlela Quality to High Quality in the conversion options. That re-encodes the video at the highest quality setting (CRF 18 for H.264 and VP9 output), which keeps the most detail at the cost of a larger file. The default, Balanced, uses the standard setting. The MPEG output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. Okuqukethwe yi-MPEG-1 noma i-MPEG-2 video ne-MP2 umsindo; ukuxhuma kanye nesakhiwo se-GOP kufana nehele le-.mpeg. Ividiyo yi-MPEG-1 noma i-MPEG-2 ne-MP2 noma i-AC-3 umsindo, ehlukaniswe ibe yizinkulumo ezilungiselelwe ukucutshungulwa nge-hardware esebenza kahle.

Ingabe MPG ingaguqulwa ibe MPEG ngaphandle kokuphinde ubhale kabusha ividiyo?

Hayi, hhayi kule khasi. MPG ne MPEG zihlanganisa isakhiwo esifanayo esingaphansi, kodwa umguquli uphinde uhlanganise ividiyo lezinhlamvu ezimbili endaweni yokukopisha umsinga, ngakho-ke kuthatha isikhathi eside kunalokho okushintshayo kwebhokisi futhi isithombe sicindezelwe futhi. Khetha Ubunjani Obuphezulu ngezansi kweBunjani ukuze ugcine iminingwane eminingi. MPG iyi-MPEG i-program stream efanayo ne-.mpeg — isibonisi sokubhala esithathu siyi-DOS-era truncation, hhayi i-format ehlukile. I-MPEG lapha ibhekisa ku-MPEG-1 noma MPEG-2 izinhlelo ezihambayo, ifomu elijwayelekile le-Video CD bese le-DVD ne-broadcast television.

Ingabe kukhona okushintshayo phakathi kwefomethi ezimbili ezidalayo njenge MPG ne MPEG?

Uma nje ingxenye ekhethekile yemishini idinga isiphetho. Ifomethi zombili zivela kusikhathi esifanayo se-H.264, ngakho noma yikuphi ukushintshana kuthengiswa ukusebenza kahle, ukhwalithi noma ubufakazi bokuphila - kuthengiswa ukuhambisana nedivayisi eyodwa ekhethekile. Uma inhloso ukugcina isithombe esisetshenziswayo isikhathi eside, ukuguqula kwibhokisi elikhona endaweni ye-sideways. MPG ithola wonke ama MPEG-2 amaphutha - i-bitrate enzima, ukuxhuma, akukho ngezansi okuthambile - kanye nokungqubuzana kwezinhlamvu ezimbili ezibanzi zefomethi eyodwa. MPEG-2 idinga cishe izikhathi ezine kuya kwezine ze-bitrate ye-H.264 yesithombe esifanayo, futhi okuqukethwe kwayo kuvame ukuxhuma, okubukeka kubukeka ku-displays amanje.

Yini i-codec yevidiyo i MPEG isebenzisa?

Kuxhomekeka ku MPEG isiqoqi. MP4, MOV kanye MKV output ukusebenzisa H.264, okuyinto idlala ku ngempela wonke ifoni, ibrowser kanye TV. WebM output usebenzisa VP9. AVI, WMV kanye MPEG output ukusebenzisa codecs older labo amafomethi akhiwa.

Ingabe umsindo wami uzophila ukuguqulwa MPG kuya ku MPEG?

Yebo, umsindo omkhulu ohambayo udlula, uphinde ukhodwe ku-codec i-MPEG idlala, isibonelo, i-AAC ku-MP4 ne-MOV noma i-Opus ku-WebM. Ukuguqulwa okuningi kugcina kuphela umsindo owodwa (omunye onezintambo eziningi), ngakho-ke izilimi ezihlukile nezibuyekezo zilahlekile. MP4 kuya ku-MOV, ne-AVI, WMV, MPEG, FLV, VOB noma M4V kuya ku-MKV, gcina wonke umsindo ohambayo.

Ingabe ngigcina ifreyimu yesiqalo uma ngiguqula MPG ku MPEG?

Yebo. Izinga lefreyimu ligcinwa ngaphandle kokuthi ushintshe: i-24 fps MPG ihlala i-24 fps ku-MPEG. Uhlelo lwezinga lefreyimu lingaguqulwa libe yi-60, 30 noma i-24 fps. Lishintsha kuphela inani; alisusanga ividiyo noma lisuse i-3:2 pulldown.

Ingabe ubukhulu behele bushintsha kanjani kusuka ku MPG kuya ku MPEG?

Kuxhomekeka kulokho okwenzekayo kuvidiyo. MKV MP4 noma MOV nge default izilungiselelo ikhophi ividiyo umfutho engashintshiwe, ngakho ubukhulu ihlala eduze komthombo. Ezinye izibini eziningi ziphinde zikhophi: a high-bitrate MPG ngokuvamile ephuma ncane, ngenkathi ekhona kakhulu ecindezelwe eyodwa ingakhula. Ifayela elincane ngaphansi Quality inikeza inzuzo encane, futhi H.265 ku Codec isilungiselelo (MP4, MOV ne MKV) ngokuvamile ncane kuna H.264 ku quality efana kodwa idlala ku amadivayisi ambalwa.

Ingabe ihele MPEG lidlalwa ku-iPhone, Android, ne-Smart TVs?

MP4 ne H.264 idlala kunoma iyiphi ifoni, i-browser kanye TV. MOV ne H.264 idlala kunoma iyiphi idivayisi Apple kanye TVs eziningi kodwa hhayi kunoma iyiphi ifoni Android edala. MKV idinga app ezifana VLC ku-iOS, futhi WebM ikhaya e-browsers. Akukho isisetshenziswa preset kule khasi, ngakho khetha ifomu injongo isisetshenziswa sakho sisekela. I-MPEG izinhlelo zokusakaza ziyi-decoded nganoma iyiphi i-DVD player, set-top box ne-broadcast chain eyenziwe, futhi zithobela amaphutha e-bit ngokunethezeka.

Ingabe kuthatha isikhathi esingakanani ukushintsha i-MPG yevidiyo yehora elilodwa ibe yi-MPEG?

Akukho isikhathi esiqinile: sixhomekeke kude, isixazululo kanye nefomethi efanelekayo. Ukuguquka kuqhutshwa kumaseva ethu we-CPUs ngesoftware encoders; akukho GPU ukukhawulelwa. MKV kuya MP4 noma MOV ngezinhlelo ezijwayelekile zikopishe umsinga wevidiyo futhi zisheshe. Ukuphinda-ukuguqula ku-H.264 kuthatha isikhathi eside, futhi WebM (VP9) yinjongo ehamba kancane, izikhathi eziningi ezihamba kancane kune-H.264 ezivivinyweni zethu.

Yini isixazululo esiphezulu esixhaswe yi MPG kuya ku MPEG?

Umguquli awunakho ubukhulu obuphelele obuphelele; umkhawulo ubukhulu bokufaka obuvunyelwe kuhlelo lwakho, futhi ubukhulu buhlala bukhona uma ungakhethanga 1080p, 720p noma 480p. Akukho HDR ukucubungula noma ukumayelana nombala. Uma ividiyo ikhophiwe (MKV kuya MP4 noma MOV ngezinhlelo ezijwayelekile), HDR10 idlula ngaphandle kokuchofoza. Ukuphinde ubhale kabusha i-HDR10 mastering metadata, futhi ngekhwalithi, ubukhulu noma i-frame rate ilungiselelo ezinye izibini zikhuphula ividiyo kumbala we-8-bit, ngakho-ke i-HDR MPG ingabonakalisa i-washed out.

Ingabe i-MPG yami yevidiyo imfihlo ngesikhathi sokuguqulwa ku-MPEG?

Yebo. Amafayela MPG alayishwe phezulu aphathwa kumaseva ethu okuguqula, akukho muntu obhekana nawo, futhi angeke ahlukaniswe. Ukulayishwa kanye nokuguqulwa kwe MPEG kususwa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa, okushiya isikhathi sokulanda imiphumela. Bona /privacy/ ukufinyelela kunqubomgomo egcwele.

Ingabe ngingakwazi ukujika, ukucisha, noma ukujikelezisa ngesikhathi sokuguqulwa MPG kuya ku MPEG?

Akunakwesokudla. Sebenzisa /trim-video/ noma /video-cutter/ ukucisha i-MPG kuqala, noma /rotate-video/ ukujika, bese uqhuba i-MPG ukuya ku-MPEG. Ukucisha kuqala kusheshe kunaku-encoding kabusha i-MPG yonke ukushiya izithombe ezingasebenzisi.

MPG

I-MPG iyisandiso sefayela samafayela evidiyo e-MPEG-1 noma e-MPEG-2. Ngokuvamile isetshenziselwa ukudlalwa kwevidiyo nokusabalalisa.

MPEG

I-MPEG (Iqembu Lochwepheshe Bezithombe Ezinyakazayo) iwumndeni wamafomethi wokucindezelwa kwevidiyo nomsindo asetshenziswa kabanzi ukugcinwa kwevidiyo nokudlalwa.
