AI Video Upscaler — every model, compared

A fast, economical video upscaler — built for production B-roll lift, social-content upscaling, and high-volume video work where cost per second matters. Decent quality at reasonable speed; not as faithful as SeedVR2 but cheaper for batch jobs.

ByteDance's SeedVR2 in video mode — high-quality diffusion-based upscaling with factor or fixed target resolution up to 4K. Preserves the source faithfully without invented detail. The right choice for documentary footage, archival video preservation, and any work where staying true to the original matters more than creative enhancement.
