Abstract
V tej diplomski nalogi je opisana digitalizacija analognega videa v viskoko- kakovostno digitalno obliko. Povod so bile slabe obstoječe digitalizacije na platformi YouTube in veliko zanimanje za določeno zgodovinsko obdobje, ki je dokumentirano na VHS-medijih. Odprtje lastnega YouTube kanala je sprožilo resno preučevanje najboljših možnih tehnik in praks v zvezi z di- gitalizacijo. Najuporabnejše informacije so bile na forumih digitalfaq.com in videohelp.com. Tu je velika baza znanja in ljudi, ki so velik del svojega življenja posvetili tehnični plati videa in so pripravljeni to znanje deliti z osta- limi zanesenjaki. Izkazalo se je, da je potreben vložek v opremo, ki je poleg visoke cene tudi zelo redka. Poleg dobre opreme pa je tu tudi velik časovni vložek, ki se odraža predvsem v delu, ko se obdeluje zajet nekompresiran AVI-posnetek. V tej točki z naprednim urejevalnim okoljem in skriptnim jezikom Avisynth popravimo vsak kader posebej, saj je mnogokrat precej odstopanj v svetlosti, premočnih barvah in tudi motnjah v samem videu. Motnje so lahko posledica poškodovanega magnetnega traku, napak v pe- riodi ali pa napak, ki so bile prisotne že v montaži kasete. Zato je ta del digitalizacije najtežji in najbolj časovno potraten.

Title:Analog video digitization
Abstract:
This diploma documents analog video conversion techniques for producing high quality digital video. The inspiration behind it was a shear amount of badly digitized material on YouTube. The most useful information was found on forums digitalfaq.com and videohelp.com, where people from all around the world share their knowledge in video digitization. Members like LordSmurf and Sanlyn selflessly share their extensive know-how gathered by years of digitizing. Reasearch makes it clear, that investment into proper capturing equipment is needed. The fact that most of it is hard to find does not help either. Besides the expensive hardware, it is also a serious time commitment as proper digitization can take a lot of time. In the end it all depends on the state of magnetic tape and the quality of material on it. Some tapes require scene by scene restoration due to color errors, time base errors, drop-outs and artifacts due to damaged, improperly stored magnetic tape or simply bad video mastering in the production of the cassette itself.
