I got bored of reading through all the comments, so maybe someone said this already, but you can also put this expression on time (after enabling time remapping):

nthFrame = 2;
fps = (1.0/thisComp.frameDuration) / nthFrame;
posterizeTime (fps);
value

In this case I had it skip every other frame, but you would change nth frame to get your desired result. Pretty sure this does the same thing as posterize time which people have mentioned above, but just another option. I found this online after some searching after a sequence of over 2000 images were only labeled in even numbers. When I brought that in as an image sequence I would get the “missing media” error for every other frame since I had no odd numbered images. I understand the question here is related to video and not image sequences, but I’m thinking this would work pretty much the same. I’m no expressions expert, so I’m not 100% positive what’s going on here, but it worked for me for my problem. Maybe it will work for someone else on here! Just thought I’d share!

Thanks Todd! I haven’t actually tried this yet, so I may have a more specific question once I get going on it. Thanks for your reply!

One question that I do have right now though, so lets say I parent the null to a point from the 3D tracking data and use that. What happens when the camera pans and that point goes out of the frame? Would I then just choose a new point to use as the parent? How do you switch parents? Thanks!!

That worked! Thanks so much for your help. One step closer to no longer being an AE noob.
