AVI ukuba FLV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AVI ibe yi-FLV ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho ye AVI kwaye umguquli uqhube i-CRF-esekelwe kwi-encoding ephindayo ebhekisa kwi-visually-lossless FLV imveliso (i-CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne FLV isiqulathi-zifayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 yee-pipelines ezintsha. Iifayili ze-AVI zingaphambili kunee-codecs eziphambili: lindele i-MPEG-4 Inxalenye ye-2 (DivX/Xvid), i-Motion JPEG okanye iifayili ezingenakucothayo ezingenakucothayo kunokuba i-H.264. I-FLV ihlala igcina i-Sorrenson Spark okanye i-H.264 video ene-MP3 okanye i-AAC yesandi, ejikelezwe kwifomati yokuhamba eyenziweyo yokuhambisa i-RTMP.

I-AVI yevidiyo yam ibonisa imigca ye-comb kwi-movement - iya kuthatha into kwi-FLV?

Iya kwenza ukuba awuyi-deinterlace, kwaye AVI imixholo ihlala i-interlaced ngenxa yokuba ifomati ivela kwixesha le-broadcast ne DVD. Iiframes ezi-interlaced zigcina iindawo ezimbini eziphakathi-ubukhulu eziqhotyoshelwe kwishumi elinesihlanu sesibini; kwifowuni eqhubekayo-yokukhangela okanye imboniselo efunda njenge-horizontal combing nantoni na ehambayo. Yenza ukhetho lwe-deinterlace kwaye i-encoder igubungela iindawo kwi-frames eziqhubekayo ezipheleleyo phambi kokubhala i FLV. AVI yiMicrosoft's Audio Video Interleave, enikezelwe ngowe-1992 phezulu kwe RIFF chunk format - enye yezinto ezidala ezigcinwe zihlala zijikeleza.

I-AVI yam yokurekhoda ihlukaniswe ibe ziinxalenye ezilinganisayo - ngaba i-FLV inemida efanayo?

Hayi, kwaye le yenye yezona zizathu zilungileyo zokushenxisa. I AVI isiqulathi siqulethe ifayile enye esebenzayo ethe tyaba eyenza ushicilelo olude okanye oluphezulu-bitrate luqhube ngokuthe ngqo, oko kukuthi, kutheni ushicilelo oludala lufika njengenxalenye1, ingxenye2, ingxenye3. FLV ayinalo umda ofanayo, ngoko ke iinxalenye zingadityaniswa kwakhona kwifayile enye eqhubekayo. I-AVI ayinakuxhaswa kwe-codecs ekutsha, i-frame rate etshintshayo, izihloko ezimfutshane ezicocekileyo okanye iifayile ezingaphezulu kwe-4 GB ngaphandle kwe-hacks, kwaye i-chunk nganye i-overhead ikhupha ifayili.

I AVI yam inezinto ezininzi ezidlala umculo - ngaba zonke ziya kuhlala zikhona kwi FLV?

Ayithembekanga. AVI igcina imijelo emininzi yesandi njengemizila yohlobo lokuqala, kodwa FLV uxhaso lokudlala ngaphezulu kwemizila yokuqala ayihambelani, ngoko abadlali abaninzi baya kutyhila kuphela enye. Khetha imizila oyifunayo phambi kokuguqula; abanye bangcono ukutywina kwifayile zabo ezikhethekileyo kunokuba bashiye kwisiqulathi seefayili esifihlayo. AVI ilula kakhulu, oko kukuthi kutheni i-camcorders yakudala, ikhadi lokufota, iDVD isixhobo sokutywina kunye neWindows-exesha lesoftware zonke zihlala zikhupha. Akukho mkhangeli zincwadi, ifowuni okanye iTV iya kudlala i-FLV - nantoni na esele ikwi-container kufuneka ishenxiswe ngaphandle ukuze ihlale ibonakale.

Ingaba kukho incopho eguqula phakathi kwefomati ezimbini ezidala njenge AVI ne FLV?

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.

Yeyiphi i-codec yevidiyo esetyenziswa yi-FLV?

Ixhomekeke kwi FLV isiqulathi seefayili. I-MP4 imiselwe ukuba ibe yi-H.264 ukuze ixhase ukudlala okubanzi phakathi kweefowuni, ii-browser, kunye ne-Smart TVs. I-MKV imiselwe ukuba ibe yi-H.265 / HEVC ukuze ilinganise nengxenye yobungakanani befayili kwinqanaba elifanayo lomgangatho. I-WebM imiselwe ukuba ibe yi-VP9. Iinketho eziphambili zibonisa ukhetho olucacileyo lwe-codec ukuba ufuna ukucima. FLV yindawo yokugcina i-Flash Video ehambisa yonke i-web video ukusuka ngo-2003 de i-Flash ivale ekupheleni konyaka ka-2020.

Ingaba umculo wam wesandi uya kuqhubeka uguquka ukusuka kwi AVI ukuya kwi FLV?

Ewe. Xa AVI ne FLV zibelana nge-codec yesandi (umzekelo, zombini zithabatha i-AAC), isandi siphinda sixutywe ngaphandle kokubuyisela ukukhowuda - i-bit-identical. Xa ii-codecs zihlukile, isandi siguqulwa kwi-AAC / Opus / Vorbis kuxhomekeke ekubeni i-FLV ixhasa ntoni. I-audio enezithotho ezininzi (iingxelo, iilwimi ezitshintshiweyo) igcinwa.

Ndingagcina i-framerate yokuqala xa ndiguqula i-AVI ibe yi-FLV?

Ngokungagqibekanga ewe — i-24fps AVI ihlala i-24fps kwi-FLV; i-60fps AVI ihlala i-60fps. Ukuba ufuna ukuguqula umyinge (umzekelo, i-interlaced 29.97 → i-progressive 30, okanye i-60 → 30 yemida yokukhuphela), ukhetho lwe-framerate luphatha 3:2 ukutsala ezantsi, ukususa uthungelwano, kunye nokuqhekeka kwe-frame kwindlela efanayo yokufihla.

Ubungakanani befayili butshintsha njani ukusuka kwi AVI ukuya kwi FLV?

I-codec efanayo yokuphinda-phinda (AVI H.264 → FLV H.264 itshintsha kuphela isiqulathi seefayili): ubungakanani obufanayo. Utshintsho lwe-codec lunokutshintsha ngokumangalisayo: H.264 → H.265 luya kuquka ifayili kwinqanaba elifanayo lomgangatho wokubona; VP9 imalunga nokuthelekiswa; AV1 icima enye i-20-30% kodwa ihamba phantsi ukukopela.

Ingaba ifayili FLV iyadlala kwi-iPhone, Android, kunye neSmart TVs?

MP4 / H.264 idlala ngokusemthethweni kwisixhobo ngasinye esitsha. MOV / H.264 idlala kwizixhobo ze-Apple 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-FLV codec / isiqulathi esikhuselekileyo senjongo yakho. I-FLV's ephantsi ngepakethi nganye i-overhead iyenze igqibelele kwi-streaming ngaphezulu konxibelelwano olungathembekiyo lwexesha lakhe, kwaye ii-archives ezinkulu zayo zihlala zikhona.

Ithatha ixesha elingakanani ukutshintsha i-AVI yevidiyo yeyure enye ibe yi-FLV?

I-Same-codec re-mux ikwindawo efutshane-imizuzu engama-30 ukuya kwengama-60 yefayili yeyure enye. I-codec epheleleyo ephinda-ikhowudi iqhuba malunga nexesha lomthombo we-0.3-0.7x kwi-GPU yethu, ngoko ke i-1-iyure AVI → FLV igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.

Yintoni ubukhulu bomfanekiso oxhaswayo kwi AVI ukuya kwi FLV?

Ukuza kuthi ga kwi-8K (7680×4320) kwi-premium plans. Ukuguqulwa simahla kugqityiwe kwi-4K (3840×2160) ngumda wobungakanani befayili nganye. I-HDR metadata (HDR10, HDR10+, Dolby Vision xa ikhona) iqhutywa apho zombini i AVI ne FLV iinqanawa zixhasa khona.

AVI

Iifayile ze-AVI zinokuqulatha idatha yeaudio kunye nevidiyo, exhaswa kakhulu kodwa enobukhulu obukhulu beefayile.

FLV

I-FLV (iVidiyo yeFlash) yifomati yesikhongozeli sevidiyo ephuhliswe nguAdobe. Isetyenziswa ngokuqhelekileyo ukusasazwa kwevidiyo kwi-intanethi kwaye ixhaswa yi-Adobe Flash Player.
