Is the entire scene blurry or just your hands? Are you looking at individual video frames?
The Rebel T7 is not capable of Movie Servo AF. This means that the camera cannot refocus and track subjects while it is recording video
When you are shooting video, you must adjust focus prior to beginning a shoot, or you would someone behind the camera controlling the focus.
The camera is great for capturing “talking head” videos. where focus remains fixed on a seated person that does not move around.
