Possible bad engine mounts

I have been noticing that when I sometimes brake hard the car will clunk sometimes as if something is knocking against the frame or the front end of the car when I stop, as if something moved forward. Did some research online and did this test on my car where I hit the brakes and the gas at the same and as you can see in the attached video, the engine moves quite a bit. I remember replacing all of the mounts last year, and I replaced the T-bone looking mount on top of the engine as well. What do you all think?
