Walking video

How do you log walking excersise videos? I want to get a heart rate monitor soon but right now I'm relying on Mfp for estimates. I've been logging them as walking fast pace. I know walking in place burns less than walking around but the video I use incorporates front back and side to side moves. It also incorporates kicks and lots of arm movement. Do you think the fast walk option under cardio is a good one to pick or should I go with one of the slower options?
