OnePlus 12 phone video jerk problem

Hello everyone,

I have a problem on a premiere pro project. I got the rushes from a colleague who filmed with a OnePlus 12 phone in 1080p at 30 fps. When I view the rushes on Windows on VLC everything is ok. On the other hand, when I play the rushes on premiere pro, I get jerks: on the preview, on the timeline and even when I try to export. The sequence is set according to the characteristics of the rushes. I've never had this problem before. Thanks to anyone who can help me.

Hi @Anne-Charlott33205802bcfv - Can you try Neil's advice and transcode your media clips in shutter encoder, or handbrake let us know if that helps.

Shutter Encoder may also be used to convert to Constant Frame Rate:

I think you're right, R Neil Haugen. When you take a closer look, you realize that no two rushes have the same fps.

Thank you gentlemen for your answers. I tried both of Jamie's tips but it didn't help...

Hi @Anne-Charlott33205802bcfv - Thanks for submitting your bug report. We need a few more details to try to help with the issue.
Please see, How do I write a bug report?

It looks like your footage is variable frame rate, which can cause issues with playback or synchronization.

First, please check your Audio Hardware settings (under Preferences) and set the Default Input to “No Input.” This can help resolve timeline responsiveness issues caused by audio input conflicts.

Next, try right-clicking on your media in the Project panel, then go to Modify > Interpret Footage, and manually set the Frame Rate to 29.97 fps (or your intended frame rate).

Let us know if either of these steps improves things for you.
Sorry for the frustration, and we appreciate your patience!

Because that phone is not producing an actual 30fps file, with 30 frames per every second. That is CFR ... constant framerate.

What that phone is producing is VFR ... variable framerate. Where depending on the motion it detects, the phone is actually recording fewer (typical) and occasional more frames per second than the nominal "30fps" it is set to.

So in MediaInfo, Tree View, you would probably see a listing that a) it's VFR, and 2) framerate varies between say 27.697 and 31.23 fps. With an average of maybe 28.92fps.

Premiere, as all pro NLEs, is designed to work with CFR media. So using ShutterEncoder or Handbrake to convert that clip/s to CFR would be your best bet.

Everyone's mileage always varies ...
