The lower motor mount has to be bad, judging by the amount of movement. You checked the drivers side lower mount, which is the trans mount and usually lasts longer. The passenger side motor mounts are known to fail after only about 120k miles. They also cause vibration. Check that one out, I can almost guarantee it's totally destroyed like this
The amount of movement in the upper mount (in the video) is normal when the entire motor shifts in the engine bay, but I suggest flipping them since that's just as good as buying a new mount.
What a bad motor mount will look like. The motor is about 2 inches lower than it should be, and moves when shifting.
The new one is at the correct height and solved the clunk and the vibration issue.
