What is your video editing software?   Decent video editing packages have a "tracking effect", where the effect can be blur or pixelate or whatever that follows features for each continuous clip.

Premiere Pro by Adobe, I pay the month fee to get the access to everything Adobe makes.  Figured it better than taking a risk on cracked/stolen copies with god knows what in the code thanks to the russian hackers.

Still need to learn transitions effects actually, but put blending at a pretty low priority.  Spent this evening drinking whiskey and learning about color correction, and creating "tracking mattes" so i can do privacy blurs in video.

Can't wait to call up some bad mofos and get em on video showing how quiet professionals shoot.  What's funny is that some of my Tier 1 pals are secret gun nerds who love reading gun forums... but never comment thanks to all the know it all trolls that populate any forum.  Will be fun to help em put internet commandos in their place.
