Optical Flow

Free

For most videos, there's no need to modify any parameters. Simply click [Enable] to freely get ceiling-level frame interpolation results

Basic Parameters

Parameter	Explanation	Disadvantage
GPU Acceleration	Can speed up frame interpolation	May reduce frame interpolation effect, such as more jello effect. Android does not support this option
Preview	After enabling preview you can see the optical flow effect without exporting	Preview quality is lower, which will also cause project preview lag
High Definition	Interpolated image will be clearer	Export speed will be significantly reduced

Advanced Parameters

Note

Enabling the following options does not necessarily improve interpolation quality, please read carefully before using

Parameter	Explanation	Disadvantage
Reduce Jello	Reduce jello artifacts in interpolated frames	May increase ghosting
Reduce Ghosting (Use with caution)	Reduce ghosting caused by fast motion	Will increase jello effect, will also reduce interpolation speed
Remove Duplicate Frames	If there are duplicate frames in the video, the interpolation result will stutter. Enabling this option can automatically remove duplicate frames to maintain smooth interpolation.	May increase jello effect

Common Issues

Frame Interpolation Stutters

Stuttering is because there are duplicate frames in the video. You can enable the [Remove Duplicate Frames] option. Or use the original video without duplicate frames
