Hi, I see from your video that you have an Overscan Multiplier of 1.15, which seems insufficient for your camera move. You can either keep increasing that value. I often use 1.2 or more, but if you know the camera moves, and it will be mainly a left or right pan. You can just overscan in that direction.
For example, add a 10% overscan on the left and the right.
If it looks like you are losing your inner resolution because of the large overscan values. You can check Adapt Resolution = ON, and your inner resolution will be increased according to your new overscan values.
