Seeking open-source options for upscaling long 2-minute video without tiling

Fast-Cash1522 · reddit · 2026-08-22

A user generated a 2-minute video (960x544) using MiniMax H3 and wants to upscale it to 1080p with detail recovery on an RTX 3090. Previous attempts with SeedVR and RTX Super Resolution were unsatisfactory due to poor detail recovery, while LTX 2.5 required splitting the video into chunks. The user is looking for open-source tools/workflows that improve quality without tiled processing and its associated flickering artifacts.
