Kuzokwenzeka uma ungasebenzisi i-deinterlace, futhi AVI okuqukethwe kuvame ukuxhunywa ngoba ifomu livela esikhathi sokusabalalisa ne-DVD. Amafreyimu axhunywe agcina ama-fields amabili aphakathi nendawo aphezulu athathwe ngengxenye yesihlanu yesibili; kufoni noma kumboniso oqhubekayo-oqhubekayo ofunda njenge-horizontal combing nganoma yini ehambayo. Vula ukhetho lokuxhunyaniswa futhi umbhalo-mqoka uxhuma ama-fields kuwo wonke ama-frames aqhubekayo ngaphambi kokubhala i-WebM. AVI Microsoft Audio Video Interleave, wasungula ngo-1992 phezu RIFF chunk format - omunye izitsha ezidala kakhulu okwamanje e circulation.

Hayi, futhi lokhu kuyisizathu esingcono sokushintsha. I AVI iqukethe i-file eyodwa esebenza kahle eyenza ukurekhodwa okude noma okuphezulu kwe-bitrate kuhambe ngokuqondile, okuyinto ebangela ukuthi ukurekhodwa okudala kufike njengengxenye1, ingxenye2, ingxenye3. WebM ayinaso isibopho esifanayo, ngakho ama-pieces angaxhunywa kabusha kwifayela elilodwa eliqhubekayo. I-AVI ayinaso isixhaso esisemthethweni se-codecs yamanje, isilinganiso sefreyimu esiguqukayo, izihloko ezithambile noma amafayela angaphezu kuka-4 GB ngaphandle kokuhlaselwa, futhi i-chunk ngayinye i-overhead ibhoboza ifayela.

Yebo. AVI ayinaso isikhala esisetshenziswayo sesihloko esilula, ngakho isikhala sesihloko se AVI kufanele sifakwe kusithombe noma sithunyelwe njengefayela le-sidecar elilodwa.

Yebo, futhi lokho kuyisizathu esiphelele sokuguqulwa. I AVI efakwe kwikhasi lewebhu ibonisa umdlali okhubazekile noma icindezela ukulayisha, ngoba iziphequluli azikho izikhombisi ezizo. WebM idlala ngaphakathi ngengxenye yevidiyo ye-HTML5 engavamile ngaphandle kweplugin noma kusetshenziswa okungaphandle. I-WebM idlala ngokusemthethweni kuwo wonke umsakazi omusha ngaphandle kweplugin, ngaphandle kwelayisense yemali kanye nokungabonisi kwepatent, okuyenza ibe yiphutha levidiyo efakwe kwi-web.

Noma yini ofuna ukuyigcina, yebo. AVI ihlobene nohlobo oludlule lwevidiyo nesoftware efunda ngayo ihlala ihamba ihamba isuka kumafoni, iziphequluli nezinhlelo zokusebenza. Ukusuka kwevidiyo ku WebM manje, uma umqokeli ohlanzekile ukhona, kuyinto ehlukile phakathi kwegobo lomlando ongavula ngawo iminyaka eyisithupha nenye ongayenza.

Yebo — isisekelo AVI → WebM ukuguqulwa kumahhala ngaphandle kokubhalisa. I-Premium ifaka ama-limits aphezulu wobukhulu befayela ngalinye, abasebenzi abangaphezu kwe-batch, futhi isusa izikhangiso.

Ama-akhawunti amahhala: kuze kube yi-100 MB ngayinye yehele AVI. I-Premium: ngokuvamile i-1 GB ngayinye yehele, ngokuya ngohlobo lomsuka AVI. Amafayela amakhulu kakhulu ahlukaniswa abezingxenye zekhasimende lapho i-WebM ivumela.

Ukushintshana kugcina wonke ama-infos angabonisa AVI kanye no WebM. Ama-features athile wefomethi a WebM axhaswa (isibonelo, i-data ye-vector ku-raster output, amafomu ku-plain-text output) a-rasterized noma a-stripped — bona ama-notes athile wefomethi kwikhasi lemiphumela.

Yebo — susa amafayela amaningi AVI endaweni yokulayisha futhi afakwe ebhokisini ngokufanayo. I-Premium inemisebenzi eminingi efana; kuhele olune-50, lokhu kuyinto ehlukile phakathi kwemizuzu nemizuzu.

Yebo - UI iphendula futhi ukuguqulwa kwepayipi kuqhuba ikhasimende-ikhasi, ngakho-ke amadivayisi eselula akhuphula-ke-akhuphela njengedesktop. iOS ne-Android browser file pickers (ikhamera roll, Amafayela app) umsebenzi end-to-end.
