Fun with dolly zoom simulation...

Recommended Posts

Just playing with the dolly zoom concept folks...  Normally, a video camera or film movie camera would be placed on a dolly and moved either away from or toward the subject(s). Then the motorized zoom would be activated to zoom in or zoom out in perfect harmony with the camera position being moved out or moved in. The net result is that the subject(s) stay static while the background either zooms away or toward the viewer. The concept was first used by Alfred Hitchcock on the movie Vertigo in 1958...

Yes would be interesting.

Since Lin cannot answer your question now, I will try to explain to you.
The Dolly Zoom effect is a camera technique in which the main subject is practically motionless in the frame and the background is zoomed in or out. Understanding this, you can easily create an imitation of this effect. We need an image of the main object in PNG format (the background is transparent) and a rear view image with good resolution.
1. Place the image of the main subject. We place it to your liking. Set the size.
2. Below we place a layer with a background. In the first keyframe, set the background size to about 250. Or how you want. We align the horizon line, raise the image above so that our main object does not "float" in the air, but is always on the ground. Create another keyframe in the end of the slide and minimize the background size by about 100-120.
3. You can leave it this way or add small movements to the main subject for realistic camera movement. I will use modifiers. I set the values
Pan: X- Oscillation: amplitude 0.5 repeats 7
Pan: Y - Oscillation: amplitude 0.5 repeats 10
That's it, Dolly Zoom is ready!

You can also study the attached project.

Best regards,
