4K masters

Back to the 1080p comparison

3840×2160 upscales from the finished 1080p masters using Topaz Proteus 4. The revised Maria version preserves the source frames and timing without duplicate-frame repair or interpolation.

Do not judge playback here. The player streams near-lossless 4K files of 100 to 300 MB each, so playback will stutter on most connections and machines. For viewing, download the HEVC MP4 files below and play them locally. For technical evaluation, download the ProRes 422 HQ masters.

Player: select a sequence, press Play, then Switch. Keys 1 to 3 select a version, Space plays or pauses, Z shows 1:1 pixels (drag to pan), F is fullscreen. The original's soundtrack plays for every version.
