Keyframing a zoom with Field of View

- [Narrator] Dolly and zoom are two ways of making things…larger or smaller on the screen.…A dolly of course moves the camera toward or away…from the subject, while a zoom simply…crops the field of view to make things larger or smaller.…It's said that a zoom is like bringing a subject closer to…the viewer and a dolly is like bringing the viewer closer to…the subject. Most importantly, the shape of the function…curve will affect the look of the animation.…

Let's create a zoom animation. Select the camera…and go into the modify panel.…And we have specify FOV enabled,…with a field of view of 75 degrees.…Let's tighten the shot a little bit.…Reduce that degree value down to 45 and press enter.…And we'll create some key frames. Enable auto key…and go down to frame 60 on the timeline.…

With the camera still selected, change the field of view…degree value to 25 and press enter.…Now we've zoomed in, and we've got key frames.…Disable auto key, rewind and play back.…We've got a zoom, but it's not a terribly elegant one.…
