DESCRIBE THE BUG:
FCPXML currently doesn't support smooth position keyframes.

For example, the default keyframe curve is smooth, but it doesn't contain any of the bezier curve data:

<param name="position">
    <keyframeAnimation>
        <keyframe time="6700/2500s" value="-5.71162 8.05393"/>
        <keyframe time="15900/2500s" value="66.2037 37.7778"/>
    </keyframeAnimation>
</param>

TO REPRODUCE:

  • Create a new Library
  • Create a new Project
  • Add a video to the project
  • Create a position keyframe at the start of the clip
  • Go to the end of the clip and move the video in the Viewer
  • Modify the bezier curves for the keyframes
  • Export a FCPXML
  • Re-import the FCPXML
  • The original project will be visually different to the imported project.

EXPECTED BEHAVIOUR:
FCPXML should support "smooth" keyframes.


SPECS:

  • 2021 16-inch MacBook Pro (M1 Max, 64GB RAM, 8TB SSD)
