Some footage shaking before / after render

[PaperFortress]

Very confused what's going on here. I have been having various issues with footage shifting for seemingly no reason.

At first it was just clips with warp stabilizer on it, and [only] after rendering the clip it would shake/shift side to side what looked like just a few frames.

Now I'm working with a drone shot from a DJI Mavic Pro and the image dramatically shifts (20-ish pixels) to the right after every 10th frame or so.

***UPDATE*** The clip was sped up to 120%, then once I took that effect off the clip it smoothed out. This was also the case with clips with the warp stabilizer.

Any idea what would be causing these seemingly random shifts in the image? I tried to talk to Adobe customer service but they had no idea what was going on.

Thanks in advance for your help!

Export out a Cineform copy of the sped up footage, then apply Warp to that.

Thanks for this Jim, will give it a shot. Would just like to get an understanding of why I have to do this work-around. If this is something I'll have to do with every single clip like this it's not sustainable and I wonder how I can fix this moving forward or if it's just something Adobe has to fix in later versions of Premiere...

I can't shed much light on that.  I don't use either of the effects in play here.

Stebs,

Are you free of this issue yet? Let us know.

Thanks,

No, this is still a major issue and it's driving me insane. My project was fine and the warp stabilizers were working well. Now - ALL OF A SUDDEN - the issue has showed in the SAME PROJECT FILE, on clips where yesterday there was no issue. The problem arises when I render the clip, not when it's unrendered.

For the love of all that is holy please help me.
