The you’re not playing the scene in the UE5 editor, you won’t get any video from Unreal into Aximmetry. That’s the nature of Unreal and a fundamental principle for how Livesync works. Aximmetry needs to control the Aximmetry camera in Unreal, and how would it do that unless you play the scene? Livesync is mainly for building your scene and checking it in Aximmetry while you do that. During actual production you should always cook the scene.
