The video of my scene is different from the animation of the scene

[IsabelleCA]

Hello
I'm working on blocking an animation cycle, I added a head movement, to check if everything looks good before I clean it up.

I do file / Export / video via Media Encoder and the result is that the video is different from the scene, as if there was a lag in the animation of the head and the reappearance of the default arm that I made disappear set the opacity to zero, I tried different way of outputting a video, I even output a png sequence, I also changed my computer, there is nothing to do, the video remains different from the scene.
Can you help me ?

The first video is a screenshot of my scene in play, and the second video is the result when I export the video through Media Encoder.

this seems so bizarre! I don't really have a solution, but perhaps if you shared the file I could try to eheck it out?

Cheers,
