Basically when YouTube sends the video to you they compress it. Compression involves finding the patterns in the video and then encoding these patterns instead of the raw video itself. When there is a lot of foliage in the video there is not much patterns to this foliage for the compression algorithms to pick up on. It will try as best it can but essentially it will fail.
