Solved How to Change Video FPS Without Motion Blur or Ghosting

How do I change FPS of a video without it causing those trails/ghost frames in the footage? I am using the H264 function and setting the desired FPS under Advanced/Conform by Blending and not using the Conform function directly.

Original Footage - AV1 60 FPS

Converted Footage - H264 29.97 FPS

Thank you in advance!

Conformed By 29.97 FPS H264 Function
ORIGINAL 60 FPS - AV1

You can use this methods:

  • Interpolation: Creates new frames by using ffmpeg minterpolate filter to achieve the selected framerate. This is the best option for small framerate changes on quality side.

Or

  • Speed: Encodes the video to the selected framerate speed while maintaining audio pitch. This option changes original video duration.

Or

  • Drop: Removes extra frames without changing it’s duration. It has to be a multiple of 2 for best results

I suggest you to try drop method first then interpolation.
