Indlela yokuguqula 3GP ukuba WebM

Inyathelo 1: Rhweba ngaphakathi 3GP iifayili usebenzisa iqhosha phezulu okanye nge shift nendawo.

Inyathelo 2: Nqakraza kwiqhosha 'Uguqulo' ukuqala uguqulo.

Inyathelo 3: Gcina ifayile yakho eguqulweyo WebM iifayile

3GP ukuba WebM Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-3GP ibe yi-WebM ngaphandle kokulimala komgangatho?

Layisha phezulu ifayili yakho ye 3GP kwaye umguquli wethu usebenzise i-CRF-esekelwe kwi-encoding ephindayo ebhekisa kwi-visually-lossless WebM output (CRF 18 ngokumiselweyo, ngaphantsi = enkulu / ubunjani obuphezulu). I-codec ikhethiwe ukuhambelana ne WebM container (H.264 / H.265 / VP9 / AV1 njengoko kufanelekile).

I-codec eyiphi esetyenziswa yi-WebM output?

Oku kuxhomekeke kwisiqulathi seefayili. I-MP4 imiselwe ukuba ibe yi-H.264 (uxhaso lokudlala olubanzi kakhulu); i-MKV ne-WebM zimiselwe ukuba zibe yi-H.265 ne-VP9 ngokulandelelanayo ukuze kufezekiswe ukucinezela okungcono kwinqanaba elifanayo lomgangatho. Ungacima ukhetho lwe-codec kwizinto ezikhethwayo eziphambili phambi kokuguqula.

Ingaba umculo wam wesandi uya kuhlala uphila 3GP ukuya WebM uguqulelo?

Ewe - isandi siphinda sixutywe (xa i-3GP ne-WebM zibelana nge-codec yesandi) okanye ziphinde zikhowudiswe kwi-AAC / Opus / Vorbis ngokuxhomekeke kwinto exhaswa yi-WebM. Isandi esininzi (iingxelo, iilwimi ezitshintshiweyo) sigcinwa.

Ndingagcina i-framerate yokuqala xa ndiguqula i-3GP ibe yi-WebM?

Ngokungagqibekanga, i-framerate ayitshintshwanga (3GP 24fps ihlala i-24fps kwi-WebM). Ukuba ufuna ukuyitshintsha (umzekelo, i-interlaced 29.97 → i-progressive 30fps), sebenzisa ukhetho lwe-framerate, oluphatha i-3:2 pulldown kunye nokususa i-interlacing kwindlela efanayo.

Yintoni ubungakanani befayili obuhlukileyo phakathi kwe-3GP ne-WebM?

I-codec efanayo ephinda i-muxes (umzekelo 3GP → WebM apho zombini zisebenzisa i-H.264) ivelisa ubungakanani obufanayo. Iinguqu ze-codec zingatshintsha ubungakanani ngokumangalisayo: H.264 → H.265 ngokuqhelekileyo iqulethe ifayili kwinqanaba elifanayo lomgangatho wokubona; H.264 → VP9 imalunga nokuthelekiswa.

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

MP4 / H.264 idlala ngokusemthethweni naphi na. MOV / H.264 idlala kwizixhobo ze-Apple kunye ne-Smart TVs ezininzi kodwa hayi kwi-Android edala. MKV ifuna i-VLC kwi-iOS. Iinketho eziphambili ziquka "ukulungelelanisa isixhobo" esimiselweyo esikhetha i-codec / umxube webhokisi okhuselekileyo kwisixhobo esimiselweyo.

Ithatha ixesha elingakanani ukutshintsha ifayili yeyure enye ye-3GP ibe yi-WebM?

Kuxhomekeke kutshintsho lwe-codec. I-codec efanayo yoku-multiplex: imizuzwana engama-30-60 (akukho kuphinda-ukukhowude). Ukuphinda ukukhowude kwi-codec eyahlukileyo: ngokuqhelekileyo 0.3-0.7x ixesha lomthombo kwi-GPU yethu, ngoko ke ifayili yeyure enye igqiba kwimizuzu engama-18-40.

Yintoni ubukhulu bomfanekiso obuxhaswayo kwi-3GP ukuya kwi-WebM?

Ukufikelela kwi-8K (7680×4320) kwi-Premium. Abasebenzisi abakhululekileyo bathintelwe kwi-4K (3840×2160) ngomda wobungakanani befayili. I-HDR metadata (HDR10, Dolby Vision) igcinwa apho zombini i-3GP kunye ne-WebM iqulethe ixhasa khona.

Ingaba i-3GP video yam ifihlakele ngexesha lokuguqula?

Ewe - iifayile zevidiyo ezilayishwe phezulu ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu embalwa yokugqitywa. Asizukuzijonga, sizigcine, sizigcine, okanye sizinikezele imixholo. Bona /privacy/ kwifestile epheleleyo yokugcina i-data.

Ndingatywina okanye ndityhefe ngexesha lokuguqulwa kwe-3GP ukuya kwi-WebM?

Ayikumgangatho ofanayo — sebenzisa /video-trim/ okanye /video-cutter/ ukucima phambi kokuguqula, emva koko ufolose 3GP → WebM inyathelo. Ukucima nokutshintsha kwinkqubo ikhawulezayo kunekubuyisela kwakhona ikhowudi yefayili yonke ukujika kuphela.

Kutheni ifayili ye-WebM imnyama/i-pixelated xa ithelekiswa ne-3GP source?

I-bitrate-too-low imiselwe rhoqo. Ukunxulumanisa kwakhona ukusuka kwi-bitrate ephezulu 3GP ukuya kwi-bitrate ephantsi WebM kwi-CRF emiselweyo icinezela kakhulu kwimiboniso enamandla. Thobela i-CRF ezantsi ukuya kwi-16-18 (okanye misela i-bitrate ecacileyo) kwaye uphinde uqhube ukuze ubuyisele umgangatho.

Ingaba i-3GP ukuya kwi-WebM converter ixhasa izihloko zesiphelo?

Ewe — iingoma zesihloko esingaphakathi (mov_text kwi-MP4, SRT/ASS kwi-MKV) zigcinwa xa zombini i-3GP kunye ne-WebM iziqulathi zixhasa ezo. Isihloko esitywiniweyo (i-hardsub) sidluliswa ngokuzenzekelayo kuba ziyinxalenye yesakhelo sevidiyo.
