Final video does not match pre-render

Hi, I created a video today in 4K, and the final result does not look like the preview that is shown when preparing it. I carefully selected the altitude to be 1km, since that was the altitude that allowed the preview to stay on one tileset without changing, since otherwise the video looks ugly, with some tiles in different colors and it totally breaks the experience. And the final video came out with the tiles near the path rendering darker and using tiles that would only appear at <1km in the preview, with farther away tiles rendering as I expected from the preview.

How can I prevent this from happening? If the preview cannot be relied on, do I just have to try higher altitudes until the video comes out as I expect it to? I also don’t want to overshoot the altitude, since raising it means the changes in altitude of the course are not as visible and easy to appreciate.

Any help would be appreciated, I love the service, but I’ve been stung by this issue twice now, and it’s quite frustrating to end up with a video that isn’t what you signed off on.
