Indlela yokuguqula FLV ukuba Image

Inyathelo 1: Layisha eyakho FLV iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho Image iifayile

FLV ukuba Image Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-FLV video njenge-Image imifanekiso?

Layisha phezulu i FLV kwaye umguquli ubonisa umkhethi wesakhelo-sokukhupha: isakhelo ngasinye se-Nth, iisakhelo kwixesha elikhankanyiweyo, okanye isakhelo ngasinye kwisiqingatha seyure. Isakhelo ngasinye esikhethiweyo sikhowudiwe njengefayili ye-Image kwaye iseti epheleleyo ifakwe kwi-ZIP yovimba wokukhuphela. FLV yindawo yokugcina i-Flash Video ehambisa yonke i-web video ukusuka ngo-2003 de i-Flash ivale ekupheleni konyaka ka-2020. Umfanekiso apha yinjongo eqhelekileyo: umguquli ukhetha ifomati ye raster efanelekileyo yomthombo kunokuba uvumele enye kuwe.

Ndingazifumana njani ii-Image iifayili ngaphandle kwesihloko esilandelayo?

Kuphela ukuba i FLV ayizange ibhalelwe, kuba i FLV ayinayo i-subtitle ekhethiweyo yokuqhuba ukucima. Nantoni na ebonisa i FLV kwisikrini sikwimifanekiso ngokwayo, ngoko ke yiyo yonke i Image ukukhupha ivelisa kwaye akukho mmiselo ususa emva koko. apho ifayile yesubtitle eyahlukileyo ikhona ecaleni kwevidiyo, ukhuphe ukusuka kummthombo ogcine isibini sihlukaniswe kwaye ii-frames ziphuma zicocekile. Akukho mkhangeli zincwadi, ifowuni okanye iTV iya kudlala i-FLV - nantoni na esele ikwi-container kufuneka ishenxiswe ngaphandle ukuze ihlale ibonakale.

Ingaba i-Image ixhasa ukubonakaliswa ngokucacileyo?

Ifomati isebenza, kodwa umbhali akafuni i-alpha ukunika - ii-frames zevidiyo kunye neephepha ezibonisiweyo zicacile ngokupheleleyo, ngoko ke zonke ii-pixels zifika ziqinile. Isiqhagamshelanisi se-alpha sihlala sisetyenziswa emva koko: kuthetha ukuba ungacima into ephuma kwi-Image kamva ngaphandle kokuguqula i-format kwakhona. Ukukhetha isiphelo ngokuzenzekelayo kuthetha ukuba ufumana ifayile evula naphi na ngaphandle kokufuna ukuqonda malunga nee codecs kuqala.

Ingaba iifayili Image ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba Image igcina i-pixel nganye ngokuchanekileyo kunokuba ilinganise. I-1080p ihlala iwela ngaphantsi kwe-2-5 MB kwaye i-4K ihlala ngaphantsi kwe-6-15 MB, ngoko ke ukuphuma okude kudibanisa ngokukhawuleza. Oku kurhwebo oluchanekileyo xa imifanekiso i feed iqhubekeka, kwaye okubi xa zihamba ngqo kwiphepha le-web. Iindawo ezivela kuzo iimifanekiso zimiselwe kwi-JPG, iindawo ezivela kuzo ezibonisa ngaphaya okanye imida eqinileyo zimiselwe kwi-PNG, kwaye iindawo ezivela kuzo iiphepha ezininzi zivelisa umfanekiso omnye kwiphepha ngalinye.

Uphi ubunzulu be-frame nganye ekhutshweyo Image ephumayo?

Ubungakanani obufanayo ne-FLV ividiyo — i-1080p FLV ivelisa i-1920×1080 Image ii-frames; i-4K FLV ivelisa i-3840×2160 Image ii-frames. Sebenzisa uncedo lokuguqula ubungakanani emva kokukhupha ukuba ufuna ii-thumbnails ezincinci okanye ubungakanani be-social-media-crops.

Ndingayikhupha isakhelo ngasinye esitsha kwi FLV njenge Image?

Ewe, kodwa uqaphele ngobalo lweefayili - i-30fps 1-minute FLV ivelisa i-1,800 Image iifayili. Sizipakisha kwi-ZIP ngokuzenzekelayo. Kwiiclip ezide, ukhetho "1 ngomzuzwana" (iifayili ezi-60) okanye iziqinisekiso zexesha elikhankanyiweyo zinika isiphumo esiphathwayo.

Ingaba imifanekiso ekhutshweyo Image iya kugcina umbala ophakamileyo FLV?

Ewe — umbala uguqulwa kwikhowudi nge-matrix esetyenziswa ngumboneleli FLV (BT.709 ye-HD, BT.2020 ye-4K HDR). Umboneleli we-HDR udweliswe nge-tone-mapping kwi-SDR xa uphuma kwi-Image kuba i-Image ifomati (PNG, JPG) ayikwazi ukugcina i-HDR pixel ranges ngokusemthethweni.

Lithini ubungakanani befayili yesakhelo esitshatweyo Image?

Ixhomekeke kwisisombululo kunye ne-Image codec. I-1080p PNG frame ihlala i-2 ukuya kwi-5 MB; i-1080p JPG kwi-quality-85 i-200 ukuya kwi-500 KB; i-4K PNG i-6 ukuya kwi-15 MB. Kwimeko egqithisileyo, ukukhupha i-PNG frame nganye ye-10-minute 1080p FLV kwenza ~50 GB ngokupheleleyo.

Ingaba i-Image ekhutshweyo igcina i-EXIF metadata yekhamera?

Isiqulathi seefayili FLV asigcinanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isebenza ngayo, ngoko ke ii-Image iifayili ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa umhla wokugqitywa kwesakhelo somthombo ukuze uphinde ulungelelanise i-bundle ngokulandelana kokuthatha.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka ku FLV ukuya ku Image?

Ukukhupha isakhelo kukhawuleza - ngokuqhelekileyo 20 ukuya kwi 30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. Imini emihlanu FLV → Image iqela ligqiba malunga nemizuzu ngaphandle kokucinga ngobalo lwesakhelo, kuba ibhotile yengxowa yi Image encoder, hayi i FLV demuxer.

Ndingazikhuphela iifayili kwixesha elikhankanyiweyo kwi FLV?

Ewe - ukhetho oluphambili luyakwamkela uluhlu oluhlukaniswe nge-comma lweziqinisekiso zexesha (umzekelo `00:01:23,00:05:00,00:10:42`) kwaye luvelisa ifayile enye Image ngesatifiketi sexesha ngasinye. Isetyenziswa kwizifundo ezincinci zesahluko, iziganeko ezibhekisa kwimifanekiso, okanye izifundo ezide ezibonisa imifanekiso emifutshane.

Ingaba i-FLV yevidiyo yam ifihlakeleyo xa ikhutshwa i-frame?

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngalinye. Ividiyo yombhalo kunye nee-Image ze-frames ezikhuphiweyo ziqhubekekiswa kubasebenzi abakhuselekileyo kwaye zicinywe kwimizuzu; akukho hlaziyo lomuntu, akukho qeqesho lwe-corpus, akukho kufikelela kweqela lesithathu.

FLV

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

Image

Iifayile zemifanekiso, ezifana neJPG, PNG, kunye neGIF, zigcina ulwazi olubonakalayo. Ezi fayile zingaqulatha iifoto, imizobo, okanye imifanekiso. Imifanekiso isetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanya uyilo lwewebhu, imidiya yedijithali, kunye nemifanekiso yamaxwebhu, ukuhambisa umxholo obonakalayo.
