What is this Technique Called? How is it Done?

For example:

A long shot of a man sitting down on a bench. An object passes by in front of the lens. By the time the object passes, the camera has cut to a close up of the man's face.

I use Premiere Pro & AE. Does this technique have a specific name? Anybody know how I might be able to replicate something similar?

You're talking about a "wipe", where the border of the transition from one scene to moves horizontally across the screen. To do what you're describing you have to shoot similar objects crossing in front of the camera at the same apparent speed in both the long shot and the close-up, then use a wipe in the same direction as the moving object, timed to move at the same speed as the object. If the moving object fills the screen, has little discernible detail, and has the same exposure and colour balance in both shots, then the actual wipe transition can be pretty much invisible, particularly if the "edge" of the wipe is a gradual feathered gradient instead of a hard edge.

Couldn't you also so a wipe using the standard wipe transition which is available in most higher-end video editing programs? The initial shot would be the man at a distance with a person passing between man and camera. The second shot would be a closeup of the man's face. In editing, the last several frames of the "man passing" would be cut, the face closeup would appear immediately in the second clip, and the wipe transition would be used to link the two clips.

I was actually describing the standard wipe transition, but using it in conjunction with material shot specifically to match it. You could do it as you describe, but it wouldn't look as seamless. If you have control over the production, then you'd want to capture original footage that will best produce the effect you're looking for.

Thanks for the tips guys. Yeah, ultimately I want to produce a seamless shot, similar to the method Sean outlined. I'll give it a shot.

I'll also try filming an object passing in front of the camera, then rotobrushing it and applying it as a separate layer as a transition between the long shot and close up, masking appropriately.

Whooh! rotobrushing....separate (video) layer..... Good to know that things like that can be done but you guys are several steps ahead of me. I need to stay with more basic stuff for a long while now.
