Optical Flow 9.0

Note

As the Optical Flow version updates, the parameters may also change. For example, starting from version 9.0, we have temporarily removed the GPU Acceleration option, as the current performance is already sufficient. We may bring the GPU Acceleration feature back in future versions.

HD

By turning on this option, you can get higher resolution result, but it takes much more time.

Preview

After enabling preview, you can play and check directly within the project. However, please note that in preview mode the quality is lower and it may cause the project to lag.

Motion Sensitivity

For fast-moving objects:

• Lower values weaken the optical flow, resulting in ghosting instead.
• Higher values strengthen the optical flow, but may cause noise due to accuracy problem.

Smooth

Higher values increase calculation time and ghosting:

• For Motion Blur, you can moderately increase this parameter.
• For Frame Mix, you can moderately decrease this parameter.

Remove Duplicate

If there are repeated frames in the video, the result will be choppy. After turning on this option, repeated frames can be automatically removed to keep the result smooth.
