How do you fix a video clip that looks jittery after importing it?

[SEA_One]

I have imported the file.

Within the source panel, the video is jittery. I am a beginner.

I have tried rendering the file within premier but the video is still jittery.

Does anyone know how to fix this?

Thank you.

My OS is Big Sur.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn't work, try creating a new project and import the old one into it.

Many users are having issues with VFR. If the file is variable frame rate, use Hand brake to convert to constant frame rate:

I used handbrake and I did not change any of the settings within it. After it finished, I imported that file and that file worked.

What exactly did it change on the file?

Thanks.

SEA,

You changed the frame rate from a variable rate one that Premiere Pro couldn't deal with to a constant frame rate which it expects. Many mobile devices and screen capture utilities produce variable frame rates, unfortunately.

Hope that helps.

Thanks,
Kevin
