The encode at 1080p does its job without major complaints— if you manage expectations. Given this is likely a pre-retail source, the grain structure from the live-action/CG hybrid is surprisingly well-preserved. Stitch’s blue fur doesn’t macroblock during fast motion (e.g., the spaceship chase or the "Aloha ʻOe" red-eye sequence). However, shadow detail on Kauai’s night beaches crushes to near-black in scenes below 3,000 kbps. The x264 codec handles the tropical daylight scenes beautifully—bright reds (Nani’s surfboard) and ocean blues pop without bleeding. | | -crf 18 | Near‑lossless quality for HDR 4K
