Abstract	U radu je opisan H.265 standard koji je trenutno jedna od boljih opcija za kompresiju video sadržaja, te je danas u širokoj primjeni. U novije vrijeme, sve više usluga podržava kodiranje videa na različitim prostornim i vremenskim rezolucijama kako bi se njihovom optimalnom kombinacijom dobio najbolji omjer kompresije i kvalitete. U okviru ovog rada, primjenom H.265 kodera, komprimirano je pet videosekvenci različite složenosti u širokom rasponu kodnih brzina, te na više prostornih i vremenskih rezolucija. Analiziran je utjecaj promjene vremenske i prostorne rezolucije na kvalitetu videa, te je za korištene sekvence predložen optimalni izbor vremenske i prostorne rezolucije za dani raspon kodnih brzina. Opisan je načini kodiranja odabranih video sekvenci, način mjerenja kvalitete dobivenih dekodiranih sekvenci, te su dani rezultati ocjene kvalitete kodiranih videa nakon dekodiranja i vraćanja na originalnu rezoluciju 4K i 120 fps.
Abstract (english)	This paper describes H.265 standard, which is currently one of the better options for video compression and is widely used today. Recently, more and more services support video encoding at different spatial and temporal resolutions to obtain the best compression-to-quality ratio throught their optimal combination. In this paper, using an H.265 encoder, five video sequences of varying complexity were compressed at a wide range of bit rates and at multiple spatial and temporal resolutions. The impact of changing temporal and spatial resolution on video quality was analyzed, and an optimal choice of temporal and spatial resoluton for the given range of bit rates was proposed for the used sequences. The encoding methods of the selected video sequences were described, as well as the method for measuring the quality of the obtained decoded sequences. The results of quality assessment of encoded videos after decoding and upscaling them back to original 4K and 120 fps resolution.
