Topaz Frame Interpolation

Frame interpolation estimates motion between existing frames rather than generating a new scene. Aion targets large, complex motion, Apollo is tailored to non-linear or slightly blurred motion and exact frame multiples, and Chronos covers general frame-rate conversion; abrupt cuts and extreme frame-to-frame changes remain poor interpolation boundaries.

How to use this model

  1. 1

    Upload the highest-quality progressive source available and trim away unrelated shots before processing.

  2. 2

    Choose Aion for large or complex full-frame motion, Apollo for non-linear motion or exact multiples, or Chronos for general retiming.

  3. 3

    Set the target frame rate or slow-motion factor without crossing hard scene cuts.

  4. 4

    Inspect fast edges, thin objects, reflections, water, and occlusions frame by frame for warping or duplicate frames.

  5. 5

    Treat audio separately when retiming, because frame interpolation changes the picture track rather than rebuilding sound.

aion-1Available

Aion

Aion is built for high-resolution inputs and large, complex motion across the frame. It enables extreme slow motion by synthesizing new frames with advanced motion analysis, minimizing duplication and instability even in demanding scenes. Aion is the best choice for footage with heavy parallax, fast camera movement, or immersive formats where maximum motion accuracy is required.

ApolloAvailable

Apollo

Apollo produces smooth slow motion and frame rate conversions while handling non-linear or slightly blurry motion reliably. It excels at structured retiming workflows, especially when precise frame multiples such as 2x, 4x, or 8x are required. Apollo Fast variant is available for quicker processing on simpler motion, making this model a flexible choice for both precision retiming and faster turnaround workflows.
