Abstract	U ovom diplomskom radu riješen je problem prikazivanja vremenske skale i snimljenog video sadržaja s greškama uočenim pri obradi video zapisa. Video zapis je niz pokretnih slika prikazanih u vrlo brzom slijedu. Problem je u tome što su izvorni video zapisi jako veliki pa ih je potrebno sažeti. Najčešće korištene tehnike sažimanja su poduzorkovanje boja i metoda skupine slika. Zbog sažimanja video zapisa javljaju se mnoge greške poput stvaranja blokova, izlijevanja boja, zvonjave i dr. Programsko rješenje je napravljeno u razvojnom okruženju Qt. Qt omogućava razvoj programskih rješenja za više različitih platformi koristeći programske jezike C++ i QML. Dio koda koji služi za čitanje zapisne datoteke i spremanje pročitanih podataka je napisan u programskom jeziku C++, a preostali dio koda je napisan u QML-u. Program sadrži vremensku skalu s oznakama za svaki artefakt i omogućuje korisniku reprodukciju video isječaka s odgovarajućim artefaktima. Također ima mogućnosti uvećavanja, umanjivanja i pomicanja po vremenskoj skali. Testiranje je pokazalo da program ispravno radi u svakom od testnih slučajeva i da je brzina izvođenja zadovoljavajuća.
Abstract (english)	This master's thesis solves the problem of displaying the timeline and saved video content with artifacts detected during video analysis. Video is a sequence of moving pictures that are displayed very fast. The problem is that uncompressed videos are very big so they need to be compressed. The most common compression techniques are chroma subsampling and group of pictures. Because of video compression many artifacts appear like blocking, color bleeding, ringing and others. The program was developed using the Qt development environment. Qt enables development of applications for multiple different platforms using C++ and QML programming languages. Part of the code that reads the log file and saves the data was written in the C++ programming language while the rest of the code was written in QML. The program contains a timeline with markers for each artifact and it allows the user to play video cuts with corresponding artifacts. Also, it provides the functionalities of zooming in, zooming out and scrolling the timeline. The testing has shown that the program is working correctly in each of the test cases and its performance is satisfactory.
