Stop Cropped Video From Moving

Hello!
I am new to using Final Cut Pro. I am currently working on a project where I am trying to get five videos playing on the screen at the same time. I have mostly figure it out except for one issue. My video cropping keeps moving to a different shape and I’m not sure what’s causing it. It’s like there are two different video settings on the one video and it transitions to the second one half way through. If anyone knows what I could be talking about, I would appreciate some insight. Thank you!

There is no link to a video.

Hi Dani, Welcome to the forums
We are going to need more info and maybe a screenshot of your timeline.
How are you setting up the multiple (5) clips?
Is only one of the clips moving/changing or does this affect all the clips?
Are clips changing position, scale, size, crop????
Is it possible you used the "Ken Burns" effect? That would create a zoom effect.
Click on the clip(s) and open the inspector window and look for any animation that has been applied. Look for keyframes and changes in X/Y coordinates/scale etc… Note you should see all your positions, but if the problem is a clip is moving out of position, you are looking for the animation or change of parameters over time and scrubbing thru clip will show changes to inspector window info.

More info really needed…
Hope this Helps, Greg
