Rounded Crop not working correctly

Hi ​@Vadym B. 
Thanks for providing the video.

From the recording, it looks like you're animating the Rounded Crop effect and seeing a mismatch between the keyframed crop values and the resulting shape displayed in the Program Monitor. I can see that you're testing both Symmetrical Crop enabled and disabled and observing similar behavior.

A few questions that would help narrow this down:

• Does the issue occur in a brand-new project with a simple graphic or color matte?
• Are the affected keyframes Linear, Bezier, or Ease In/Out?
• Does the final export match what you see in the Program Monitor, or is the discrepancy only visible during editing/playback?
• Is the clip also using Motion, Transform, Scale, or nested sequences?

If possible, could you also provide a short sample project or identify the specific timestamp in the recording where the displayed crop differs from the expected keyframe value?

Thanks for the video—it makes the issue much clearer than the written description alone.
