Michelle,
First, the starter appears to be loose. Have you confirmed it is tight? Next, if the starter is tight, then the new starter isn't good. There is a Bendix solenoid in the starter that is to kick a drive gear outward to engage with the flywheel. That doesn't appear to be happening unless the starter is that loose enough to prevent it from reaching the flywheel.
Watch your video. See if you feel it appears to be moving when you engage the starter. It could be my imagination.
When you installed the new starter, did it go together easily?
Let me know.
Joe
