Setting the Right Parameters?

I built a 450 quad basically for photography and it works great except it bobs up and down a lot at slow speeds and the gimbal can’t completely correct for this. Are there any parameters I can change to fix this?

Please clarify “bobs up and down” a video would be great.
If you mean the landing gear swinging that is due to the weight distribution.
Also upload a log to and post a link to it so we can get an idea of the tuning.
