Abstract:V diplomskem delu smo primerjali novejše kodeke za stiskanje videoposnetkov, kot so H.264/x264, H.265/x265, H.266/VVenC, AV1/libaom in VP9/libvpx, z namenom identificirati njihove prednosti in slabosti. Osredotočili smo se na vpliv izbire kodekov in nastavljenih parametrov na kakovost slike ter učinkovitost stiskanja. Preučili smo tudi, kako različni tipi videoposnetkov, na primer visoko dinamični posnetki, statični prizori in videi z visoko ločljivostjo, vplivajo na delovanje kodekov. Primerjali smo stopnjo stiskanja, vpliv na velikost datoteke, čas stiskanja in končno kakovost slike. Za merjenje podobnosti smo uporabili metriki PSNR in SSIM. Ugotovitve raziskave ponujajo smernice za izbiro najučinkovitejših rešitev glede na specifične potrebe uporabnikov.

Title:Comparison of video compression codecs
Abstract:In this thesis, we compared modern video compression codecs, including H.264/x264, H.265/x265, H.266/VVenC, AV1/libaom, and VP9/libvpx, with the goal of identifying their strengths and weaknesses. The focus was on the impact of codec choice and parameter settings on image quality and compression efficiency. We also examined how different types of videos, such as highly dynamic scenes, static scenes, and high-resolution videos, affect codec performance. We compared compression ratios, file size impact, compression time, and final image quality. The PSNR (Peak Signal-to-Noise Ratio) and SSIM (Structural Similarity Index) metrics were used to measure similarity. The findings of this research provide valuable guidelines for selecting the most effective solutions based on specific user needs and requirements.
