Weird Visual Movement in Clip with Static Position Keyframes

[carlos_6586]

Hi, I'm experiencing a strange issue in Premiere Pro.

I'm working with a horizontal video inside a vertical sequence (2160x3840, TikTok format).
I scale the video to fill the frame and use position keyframes to animate movement (like following the mouse).
The problem is: even though the position values don’t change, the video visually shifts on the very next frame after the keyframe.
There are no hidden keyframes, everything is set to Linear interpolation, and the only active stopwatch is for Speed. No effects applied.

Has anyone else run into this? Any known fix?

Thanks in advance!

Time remapping/speed stopwatch is default on.

Make a copy of the sequence (to fall back on if needed) and then try deleting and recreating the keyframes.

I've had that happen, and it fixed it for me.

Hi @carlos_6586,

Welcome to the Premiere Pro forums. In addition to @Ann Bens and @Peru Bob's suggestion, could you provide more details on how the video is visually shifting? For example, is only the position shifting, or is the scale changing as well? Are the rest of the frames afterwards affected? (A screen recording could also be very helpful).

And just checking, is your speed set to 100% and are there any frame holds being used at all?

Sorry for the frustration,
Dani

Hi @Dani_V. 

Thanks for your response!

Speed is at 150%, no frame holds, and no effects applied.
The weird part is that the video shifts visually right after the keyframe, but the position and scale values don’t change at all.

I’m attaching a screen recording so you can see exactly what’s happening.

Let me know if you catch anything!

Thanks again,

Most likely your Spatial keyframes are set to auto bezier.

Thank you for the screen recording @carlos_6586. Does this happen if you add another keyframe right after (same position values) or change the last keyframe to a hold keyframe? Or a further test, if the clip speed is at 100%? If your keyframes are set to linear (both temporal and spatial) and resetting or redoing them isn't making a difference, I'm wondering if the speed change on the screen recording (which is likely variable frame rate footage) is affecting the keyframing. Another workaround you could try is if you nest the video with the speed change, and apply the position keyframes to the nest instead, or vice versa, but keeping the two effects separate.
