This is the version history, or change log, for all the released versions of NNRetime (latest official release at the top).

v1.0.0 – July 2026

  • Neural network frame interpolation and retiming, synthesizing in-between frames from the two surrounding source frames.
  • Two timing modes: “Output Speed” (retime by a speed factor) and “Frame” (map a keyframeable source frame to each timeline frame).
  • Support for Nuke 13.1+ on Linux, Nuke 14.1+ on Windows and Nuke 15.1+ on macOS.
  • Support for Nuke Indie.
  • GPU acceleration with CUDA on Linux/Windows and MPS (Metal) on Apple Silicon, with the option of CPU only processing.
  • Per-channel processing with a “channels” knob (RGBA by default, optionally all layers, with alpha handled by a second interpolation pass).
  • Automatic large-image tiling for frames too large to fit in GPU memory, with cross-fade blending.
  • Dedicated render-license support and Nuke –gpu device override for farm rendering.
