Same here with the quality etc. I suspect it has to do w/ the resolution of the video not matching the plane perfectly… but no clue. I suppose it’s worth trying to tweak some of the material settings.
My surprise and delight with how easy it is to include a video IN the game world was met with equal frustration and disappointment that I cannot directly hijack the cinema camera w/ my video. Seems like a pretty huge QoL issue for the cinematics editor.
This lack of feature alone is causing me to edit my cinematic scenes in another program… which makes me sad.
