Even when I try to update the software, change some graphics card settings, or use a different codec, I still get this error.

Example (Focus on the 60fps footage and you'll see the jumps): https://youtu.be/AoKXWbntrH0

How to fix this pls?

Thank you.

First, make sure your graphics card drivers are up to date, as outdated drivers can cause video playback problems. Secondly, check your video player settings or try a different player to see if the issue persists. Also, ensure you're using a compatible codec for your system and video format. Experiment with hardware acceleration settings in your player, as toggling this option can sometimes make a difference. Finally, if you're editing the video, review your rendering settings
