Many slow-moving orange lights flying north-east into a cloud over Pennsylvania

My wife and I went for a hike in the late afternoon on Thanksgiving Day, 2021. We were driving home, turned a corner, and saw these lights in the sky (see attached photo and videos).
Despite what the camera appears to show, these lights were not flashing in any way. The camera also failed to capture the color accurately. They were an orangish color seeming to glow like a candle.
These lights silently moved from what appeared to be low altitude in the southwest to higher altitude in the northeast, each one disappearing into a cloud bank. The whole event was over in less than ten minutes.
For reference, I'm an senior managing engineer with a software company. My wife is a registered nurse. We are both in our mid fifties.
