Topaz Video AI frame interpolation uses three AI models — Apollo, Chronos, and Aion — to generate new frames between existing ones, turning 24/30 fps source into 60/120 fps smooth output or up to 16× slow motion. Apollo handles non-linear motion best (handheld shake, fast pans). Chronos is the standard for clean FPS conversion. Aion is the 2026 flagship for 4K+ at large motion. After running identical sports, animation, and dialogue clips through all three on an RTX 4070, my pick for topaz video ai frame interpolation in 2026 is Aion for top quality, Chronos Fast for batch speed — and UniFab Smoother AI when you want comparable results without the $299/year subscription Topaz adopted in October 2025. This topaz frame interpolation review covers what each model does, real RTX 4070 benchmarks, the Apollo vs Chronos decision, and a head-to-head with UniFab Smoother AI.

This topaz hdr review covers what Hyperion does, real benchmark data, the sdr to hdr topaz workflow, and head-to-head comparison with UniFab.
