AVI ukuba MPEG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AVI ibe yi-MPEG ngaphandle kokulimala komgangatho?

Layisha phezulu i-AVI ifayile kwaye umguquli wethu usebenzise i-CRF-esekelwe kwi-encoding ephindayo ebhekisa kwi-visually-lossless MPEG output (CRF 18 ngokumiselweyo, ngaphantsi = enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne-MPEG container — H.264 / H.265 / VP9 / AV1 njengoko kufanelekile.

Yeyiphi i-codec esetyenziswa yi-MPEG output?

Oku kuxhomekeke kwisiqulathi seefayili. I-MP4 imiselwe ukuba ibe yi-H.264 (uxhaso lokudlala olubanzi kakhulu); i-MKV imiselwe ukuba ibe yi-H.265 yefayili encinci nge-~50% kwinqanaba elinye lomgangatho; i-WebM imiselwe ukuba ibe yi-VP9 okanye i-AV1 (ukusasazwa kwe-web ngaphandle kwe-royalty). Ungacima ukhetho lwe-codec kwizinto ezikhethwayo eziphambili phambi kokuba i-MPEG iqhube ukuguqulwa.

Ingaba umculo wam wesandi uya kuhlala uphila AVI ukuya MPEG?

Ewe - isandi siphinda sixutywe xa i-AVI ne-MPEG zibelana nge-codec yesandi, okanye ziphinde zikhowudiswe kwi-AAC / Opus / Vorbis ngokuxhomekeke kwinto exhaswa yi-MPEG. Isandi esininzi (iingxelo, iilwimi ezitshintshiweyo) sigcinwa kwiziqulathi ezixhasayo (MKV, WebM, MP4).

Ndingagcina i-framerate eqhelekileyo isuka kwi-AVI ukuya kwi-MPEG?

Ngokungagqibekanga i-framerate ayitshintshwanga (AVI 24fps ihlala i-24fps kwi-MPEG). Ukuba ufuna ukuyitshintsha (umzekelo, i-interlaced 29.97 ukuya kwi-progressive 30fps) ukhetho lwe-framerate luphatha 3:2 ukutsala ezantsi nokungaqhekezi kwindlela efanayo — akukho sibini sokukhupha ikhowudi esifunekayo.

Yintoni ubungakanani befayili obuhlukileyo phakathi kwe-AVI ne-MPEG?

I-codec efanayo ephinda-i-muxes (H.264 zombini AVI kunye ne MPEG) ivelisa ubungakanani obufanayo. Iinguqu ze-codec zingatshintsha izinto ngokumangalisayo: H.264 -> H.265 ihlala iquka ifayile kwinqanaba elifanayo lomgangatho wokubona; H.264 -> VP9 imalunga nokuthelekiswa; AV1 ngoku incinci ngexabiso lexesha elicocekileyo lokukopela.

Ingaba ifayili ye MPEG iya kudlala kwi-iPhone / Android / Smart TV?

MP4 / H.264 idlala naphi na ngokusemthethweni. MOV / H.264 idlala kwizixhobo ze-Apple kunye ne-Smart TVs ezininzi kodwa hayi kwi-Android edala. MKV ifuna i-VLC kwi-iOS. I-WebM idlala kwi-browser kodwa hayi kwi-Smart TV apps ezininzi. I-"isixhobo sokuhambelana" esimiselweyo kwiinketho eziphambili ikhetha i-codec / i-container ekhuselekileyo yenjongo yakho.

Ithatha ixesha elingakanani ukutshintsha ifayili yeyure enye ye-AVI ibe yi-MPEG?

Ixhomekeke kutshintsho lwe-codec. I-codec efanayo yoku-multiplex: imizuzwana eyi-30-60 (akukho kuphinda-kukhowude). Ukuphinda-khowude kwi-codec eyahlukileyo: ngokuqhelekileyo 0.3-0.7x ixesha lomthombo kwi-GPU yethu ye-pipeline, ngoko ke i-1-iyure AVI -> MPEG igqiba kwimizuzu eyi-18-40; i-AV1 yoku-khowuda ihamba 2-3x ngaphantsi.

Yintoni ubukhulu bokubonisa obuxhaswa yi-AVI ukuya kwi-MPEG?

I-HDR metadata (HDR10, Dolby Vision) igcinwa apho zombini i-AVI kunye ne-MPEG imixholo kunye nee-codecs zixhasa khona; amacebo e-SDR ahlala e-SDR.

Ingaba i-AVI video yam ifihlakele ngexesha lokuguqulwa kwe-MPEG?

Ewe - iifayile zevidiyo ezilayishwe phezulu ziqhubekekiswa kubasebenzi ababekwe ngokuzimeleyo kwaye zicinywe kwimizuzu yokuphela. Akukho kuhlaziyo lomuntu, akukho kugcina ngaphezulu kwefestile ebhalwe phantsi. Bona /privacy/.

Ndingatywina okanye ndityhefe ngexesha lenyathelo AVI ukuya kwi-MPEG?

Ayikumgangatho ofanayo — sebenzisa /video-trim/ okanye /video-cutter/ ukucima i-AVI kuqala, emva koko ufolo i-AVI -> MPEG uguqulelo. Ukuguqula-ukusika-ukuguqula kukhawulezayo kune-ukubuyisela kwikhowudi ifayile yonke ukucima kuphela i-output.

Kutheni i-MPEG ifana ne-AVI?

I-bitrate-too-low imiselwe rhoqo. Ukunxulumanisa kwakhona i-bitrate ephezulu AVI kwi-bitrate ephantsi MPEG kwi-CRF emiselweyo icinezela imiboniso enezithuthi ezinzima kakhulu. Thobela i-CRF ezantsi ukuya kwi-16-18 (okanye misela i-bitrate ecacileyo) kwaye uphinde uqhube ukubuyisela umgangatho.

Ingaba i-AVI ukuya kwi-MPEG converter ixhasa izihloko zesiphelo?

Ewe - iingoma zesihloko esingaphantsi ezifakwe ngaphakathi (mov_text kwi-MP4, SRT / ASS kwi-MKV, WebVTT kwi-WebM) zigcinwa xa zombini i-AVI kunye ne-MPEG iziqulathi zixhasa ezo. Iingoma zesihloko ezitywiniweyo (ezinzima) zidluliswa ngokuzenzekelayo kuba ziyinxalenye ye-pixel data.
