MOV → GIF

Yebo, futhi kuyindlela esheshayo yokuthola isikhathi ofuna. I MOV igcina izihloko eziphawulwe ebhokisini njengeziqephu zesikhathi ezibizwa ngegama, ngakho uhlu luyafunda ngokuqondile kusuka kuhele futhi i-in-point ifakwe endaweni yokuqala isikhathi endaweni yokuzama ukubheka. Vumela isikhathi eside futhi kuphela lesi siqephu sizokhishwa, ngakho-ke ubude bokugcina i-MOV akuyona inkinga uma kukhulunywa ngomsebenzi othatha isikhathi eside. MOV yifomethi abashicileli abaqeqeshiwe bacela, ngoba ihlala iphinda i-round-trips nge Final Cut Pro, Premiere ne DaVinci Resolve ngaphandle kokulahlekelwa kohlobo.

Ngokuyinhloko ulungele ukuqondiswa. A MOV yifayela le-ISO base-media, futhi le mindeni irekhoda ukujikeleza njengeflegi ebhokisini ngaphezu kokujikeleza ama-pixels — ngakho-ke iclip ethweswe phansi ngefoni ingabonakalela ekudlaleni futhi ihlale ecaleni layo elinye. Ukuphila kukhiwa kusuka kuma-pixels aqoshiwe, ngakho-ke i-flegi kufanele ihlolwe ngaphambi kokuba ifreyimu yokuqala ibhalwe; uma ukubukela kuqala kubuyela emuva, jikelezisa umsuka futhi uyiguqule futhi. Konke okuthile mayelana nekhamera noma umhleli wokurekhoda kuyinkinga elula: i-video track eyodwa, umsinga owodwa oqinile wefreyimu. I-MOV ivame ukuthwala i-H.264 noma i-HEVC yokudlulisa, noma i-ProRes uma iyi-editor master, kanye ne-AAC noma umsindo we-PCM ongacindezelwa.

Ngenxa yokuthi MOV ayisiyo ibhokisi le-browser, idinga ukuxhaswa, futhi i-build elawula i-browser ishintsha kakhulu kune-garantie. Ishintsha lutho mayelana nokuguqulwa - ihele liqokwa ikhasimende-ikhasi, ngakho-ke ibhokisi le-browser liphoqelela ukushintsha ngokugcwele kanye nelinye livumela, futhi akukho bhokisi le-codec elidingayo ukuyisebenzisa lapha. Kufanele ukwazi ukuthi indlela yokuhweba isebenza kanjani, kepha: i-GIF ephilayo ebuyayo iyifomethi yonke i-browser iyenza, ngakho-ke lokhu kususa i-clip kusuka kulokho i-web ayizokwazi ukuchofoza kulokho izokwenza. Amafayela MOV akhulu, futhi ngaphandle kwe-Apple ecosystem ukusakazwa kosizo kuncane kuna-MP4 - Android edala futhi ezinye Smart TVs zizozivumelanisa.

Akukho — a GIF iyifayela lesithombe, ngakho iqala ngesikhathi ikhishwa futhi ayihambisani nokudlala, ukuyeka noma ukulawula okugqwala nganoma yikuphi. Lokhu kuyinto yefomethi ngaphezu kwekhasi elihlala kulo, futhi yilokho okubangela ukuthi ifreyimu yokuqala ibaluleke kakhulu lapha kunalokho okuzokwenzeka kwividiyo: abafundi abacela ukuhamba okuncishisiwe, nabangani be-imeyili abaveza ifreyimu eyodwa kuphela, bona lefreyimu futhi akukho okuningi. Khetha indawo yokuqalisa lapho ifreyimu yokuvala ifunda khona ngokunengqondo.

I-animated GIF isebenza kahle kakhulu kuma-clip angaphansi kwemizuzu engu-10. Ngaphesheya kwalokho ama-balloons wefayela (i-GIF ibalulekile nge-frame ngayinye engacindezelwa). I-animated ede kakhulu idinga i-WebP noma i-APNG esebenza kahle, zombili zisebenzisa ukucindezelwa kwevidiyo-codec-grade futhi zilinganiselwe kahle.

I-GIF ephilayo: 2 kuya ku-8 MB ku-480p ngokuya ngezinkinga zokuhamba. I-WebP ephilayo: 200 KB kuya ku-1 MB ku-resolution / quality efanayo. I-WebP ephilayo i-5 kuya ku-10x ingcono kune-GIF ku-quality ebonakalayo efanayo. I-GIF ayilahleki kodwa iphoqeleke kumbala we-256-palette ngefremu ngayinye, usebenzisa ukucindezeleka kwe-LZW nokucacile kwe-binary ngombala owodwa.

Ngokungajwayelekile sikhuphula isampula ku-15 fps ye-GIF ephilayo (ibhekana nobunzima ngaphezu kuka-25 fps) kanye ne-24 fps ye-WebP / APNG ephilayo (ephatha ama-rate aphezulu ngokucophelela). Nciphisa nge-frame-rate option uma umbukeli wakho uxhasa i-source rate.

Akukho — amafomethi GIF aphilayo (GIF, WebP, APNG) angagcina umsindo. Uma ufuna umsindo, bheka ibhokisi levidiyo (MP4, WebM) endaweni yefomethi yesithombe esiphilayo.

Yebo - isinqumo sokubalwa kwe-loop silawula ukuthi ngabe GIF i-loops iphela (iphutha), idlala izikhathi N, noma idlala ngokugcwele kabili. Ukubalwa kwe-loop kugcinwa ku GIF i-metadata yokuqoqa futhi kuhlonishwa yinoma iyiphi imboniso yamanje.

Izizathu ezimbili ezivamile. Okuqala, ukusatshalaliswa kwefremu-rate: 15 fps GIF kusuka ku-60 fps MOV kususa i-75% yefremu; lungisa nge-frame-rate slider. Okulandelayo, ukusatshalaliswa kwephakeji: i-GIF iphele kuma-256 amamibala futhi i-gradient-heavy MOV i-dithers ngokubonakalayo. Yishintshe ku-WebP ephilayo ukuze kube nombala ogcwele.

Yebo — ukhetho lokushintsha ubukhulu luyinciphisa i MOV ngezansi ngaphambi kokukhipha ifreyimu, okunciphisa kakhulu ubukhulu behele GIF. I-480p GIF kusuka ku-4K MOV incane kakhulu kune-16x 4K GIF. Sebenzisa /video-cutter/ ukugoqa ngenyathelo elilodwa.
