MPG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni ifayili yevidiyo ye-MPG?

I-MPG yindawo yokugcina ividiyo egcina enye okanye ngaphezulu i-video streams, iingoma zesandi, kunye nesihloko esikhethiweyo. Iindawo zokugcina ezahlukeneyo zixhasa ii-codecs ezahlukeneyo, ngoko ukulungelelaniswa kuxhomekeke kumqolo ONokubakho ngaphakathi.

Yintoni inkqubo ye-MPEG yokuhamba, kwaye kutheni ifayili yam injalo?

I-multiplex eyenziwe ukuba ikhowudiwe yi-hardware esebenzayo eqinileyo ngexesha elibonakalayo, ayikwazi ukuhlela kwikhompyutha. Iipakethi zesandi nevidiyo zidityanisiwe namaphawu okulinganisa ixesha ukuze ibhokisi esetiweyo ephezulu ingaqala ukudlala ukusuka naphi na kwi-stream, ngaphandle kwesikhokelo kunye nokungagcini phantsi ifayile yonke. Lo yilo luthetha ukuba MPG imixholo idlala kwizixhobo ezidala ngaphandle kwengxaki kwaye ingqubana nesoftware yakudala rhoqo. Okuqulethwe yi-MPEG-1 okanye i-MPEG-2 ividiyo ene-MP2 umsindo; ukudibanisa nokwakhiwa kwe-GOP kufana ne-.mpeg ifayili.

Kutheni inkqubo yokusebenza yokusasaza nokubhala ifuna MPG?

Kuba umbhobho wonke wakhiwa kuwo. Abancedisi abadlalayo, i DVD ebhaliweyo isixhobo kunye nenkqubo yokuthatha inkqubo yacaciswa malunga nale fomati xa yayikhona, nezixhobo ezineminyaka emibini yobomi benkonzo ayikwazi ukucaciswa kwakhona. Iifayile eziphumayo ezinkqubo zifomati yenkqubo eyenziweyo ukuvelisa, hayi ukhetho olunokwenziwa kutsha nje. MPG yi DVD yoshicilelo lwesoftware yolubanzi, i-camcorders edala kunye nezixhobo zokusasaza ukutya ziyazi, ngoko ihlala isetyenziswa kwezi ntambo.

Ingaba i-MPG ifana nefomati yesinye isiqalelo?

Ewe. Eli xhulumaniso negama elide okanye elifutshane obona ngaphaya kwayo lichaza ifomati enye ephantsi, kwaye nantoni na efunda okanye ifunda zombini. Amagama amabini akwimbali: umda wegama lefayile leimpawu ezisibhozo ukusuka kwi DOS yexesha, umboneleli onika igama lodweliso lwenkqubo endaweni yefomati yefayile, okanye iinkqubo ezimbini eziqhelekileyo ezihlukileyo. Uguqulelo lwesibini luvelisa iziphumo ezifanayo, ngoko sebenzisa naluphi na uxhulumaniso isoftware kwinye icala ilindele.

Kutheni i-browser yam ingadlala ifayili MPG?

Iibrawuzeri zithutha abacoci boluhlu olufutshane lweefomati, kwaye MPG ayikho kuyo - ilayisensi, udidi lwe codec ivumela, okanye ubudala bayo bugcina ngaphandle. Ifayile ayilahli kwaye umdlali we desktop uya kuyivula, kodwa akukho nto oyenzayo kwiphepha izakwenza umkhangeli zincwadi uyenze. Ukutshintsha kwi web- native container yindlela ethembekileyo kuphela yokudlala ngaphakathi. MPG ifumana yonke i MPEG-2 imida - i-bitrate enzima, uthungelwano, akukho sihloko esicocekileyo - kunye nokungaqhelekanga kweendawo ezimbini zokukhupha ifomati enye.

Kutheni le nto i-MPG yevidiyo yam ibonisa imigca ye-comb nantoni na ehambayo?

Kuba idityaniswe. Imixholo kule fomati ihlala ivela kwixesha le-DVD, apho iframe nganye igcinwa njengemihlaba emibini ephakathi- ubude ethathwe njengeshumi elinesixhenxe lemizuzu. Ikhusi eliqhubekekayo libonisa zombini ngaxeshanye, ngoko intshukumo phakathi kweemboniselo ezimbini ibonakala njenge combing ethe tyaba. Ukususa udityaniswe kuguqulelo ludibanisa imihlaba kwiframes ezipheleleyo kwaye i-artefact iphela. I-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo.

Ingaba i MPG iyadlala kwifowuni okanye kwiTV ngaphandle kokutywina ibhetri?

Iinkqubo zekhompyutha

Ingaba ndimele ndigcine iifayile ezintsha njenge MPG?

Ukuba into ephantsi kwendlela ifuna oku. Ifomati iyaqhubeka ivula, kwaye akukho mcimbi wokuguqula uvimba ongazibangela iingxaki, kodwa ayikwazi ukuqhubeka apho isixhobo okanye usebenziso luya khona. Kwanoma iyiphi into entsha, ifomati yangoku ayihlawuli nto engaphezulu kwaye ikhusela umjikelo olandelayo wombuzo kwiminyaka emininzi ezayo.

Kutheni uguqula MPG ukuba enye ifomati yevidiyo?

Gcina i-MPG kwi-MP4 xa ufuna ukudlala ngokubanzi - iiseva ze-web, ii-smart TVs kunye nezixhobo zokulungisa iinkqubo zonke zidlala i-MP4 ngokusemthethweni. Gcina kwi-WebM ukufaka iwebhu apho ubungakanani befayili encinci bubalulekile. Gcina kwi-MOV xa usebenza kwi-Final Cut okanye ezinye ii-Apple-native pipelines.

Ingaba uguqulelo lwe-MPG luphinda lukhowudi ividiyo?

Xa umbhalo obhaliweyo ovela kumbhali ngaphakathi kwe MPG uhambelana nombhalo obhaliweyo obekwe phambili, siyiguqula ngaphandle kokuphinda siyikhowudi (ikhawulezayo, engenakulahleka). Xa umbhalo obhaliweyo obhaliweyo utshintsha (umzekelo, iHEVC ukuya kwi H.264) ividiyo iphinde ikhowudiwe — ihamba phantsi, ngexabiso elincinci lomgangatho wohlobo.
