In addition to what Roland said, you could cover a logo with a different logo or a blank you create in photoshop. This would potentially involve motion tracking and other techniques to match cgi with real footage – which is tedious, but not nearly as tedious as cloning it out exactly matching each frame in Photoshop. For a short film I was working on last year, footage was shot in a Hallmark store, but it was supposed to be “Holiday Card Shop” for copyright reasons. Every time there was a Hallmark sign in the shot I had to cover it with a digitally created sign. (The director’s favorite phrase was, “We’ll fix it in post.”)

I did this very same effect on a short film last year. As mentioned previously we did a composite. Luckily for me our shot had the actor running on a pedestrian bridge over a road. The only difficult part was standing in the middle of the road for 10 minutes to get the footage of the cars without me dying.

I just used masks to cut out the bridge where our actor was running (that layer was the slow mo) and put it over the road layer where everything was in fast motion.

In your case, if you have your actor walking by a street, you could do rotoscoping. Shoot the actor walking, then shoot your background. That way the lighting and angles are right for your actor. The only problem with this is that rotoscoping is very tedious. If you’ve never done it before…prepare yourself. You could also bring a portable green screen.

Just out of total curiousity…why?

Zaxwerks 3d Invigorator at https://www.zaxwerks.com is quite good. Or possibly their ProAnimator.

Once you’ve edited your sequence together in Premiere just close that program, open After Effects, and import that Premiere project into AE. It brings in all the video clips already edited for you with no need for rendering or compressing. However, you do not need to compress video for YouTube anymore. YouTube’s own page tells you that the higher quality you upload it, the better it will look. They even do HD now. Look at YouTube’s help; it’ll tell you what you need to know.
The only reason you’d need to use AE at all for your family vacation videos is if you need some complicated titles or compositing.
I mean, I know I’d like to add an exploding volcano nearly engulfing my children in flaming death into my vacation videos, but I’m not going to do all that AE work while I’m ON vacation.

This question has been asked several times over the years; ever since Smallville’s been on the air. Use of the search feature would be good as you’ll find some more in-depth answers than what I’m going to give.
Can you do that in After Effects? Yes and no.
You can get the shot of the cemetery and the building sorta well, but you’re not going to get a complicated moving skeleton without a 3d program.
To do a quick fake of the x-ray vision shot of the cemetery just use the Find Edges effect and colorize it. To get a skeleton you could get pictures of an actual skeleton and using the puppet tool move it. Or you could cut the different bones out with masks on separate layers and animate them separately.

As previously mentioned, a beam effect is probably what you want to do. Adding some sparks using your favorite particle plug-in will help a lot and adding a bit of a glow using an animated mask on an adjustment layer will do wonders to sell the effect too.

The beam effect that ships with AE would be an interesting place to start. That or stroking masks… you could use the glow effect on either one to make it more realistic.

You will also want to include a particle effect (or possibly some fractal noise screened over your footage) to fake the dust from the erasing.

Foam with a flow map gradient. Check the manual, it seems like it should work nicely for you.
