Frame Interpolation

Frame Interpolation

Process of synthesizing in-between images from a given set of images to create more fluid movement or to slow down the speed of a video file.

Frame Interpolation options:

  • Choose a slow motion factor or to keep the speed the same, select none.
  • Replace Duplicate Frames will replace duplicate frames with interpolated frames.
  • Sensitivity can be raised to increase the sensitivity for removing duplicate frames. A higher setting may remove frames that are not duplicates but look very similar.


Specializes in non-linear motion and slightly blurry inputs.

  • Generates 8 interpolated frames per run, and then creates the selected output framerate from this result.
  • Faster than Chronos.
  • Use when you need exactly 2x, 4x, or 8x frame count multiple. For example, converting from 30 → 60fps at 200% slow motion would require exactly 4x the frames.

Apollo Fast

Typically interpolates files faster than Apollo, however, may produce a lesser quality output than Apollo when working with large amount of motion.

  • Recommended for use for any non-double conversions. For example, 24fps -> 29.97 or 60.
  • Use when speed is a factor.


High-precision interpolation for large media

  • More accurate than Apollo and Chronos, but more system-intensive.
  • Useful when working with large amounts of motion across the entire frame of an input video.


General frame interpolation model suitable for FPS conversion or slow-mo. Processing speed decreases linearly with the number of generated frames.

  • Recommended for slow motion beyond 8x or smaller than 4x, or FPS conversion.

Chronos Fast

Specializes in fast motion with larger changes between frames.
