How to do a zoom animation


HelpingSaveHumanity

Recommended Posts

On the sequence timeline drag the image borders to the desired length, then animate the ZOOM effect.

With the effects box scrubber (red line) at the start of the clip, adjust the Zoom parameters either by dragging the handles in preview or with the numbers.  Click the small green + to create a keyframe.

Move the line to the end of the clip and adjust Zoom to where it should end up.  This should automatically create another keyframe.  Note the Aspect Ratio box, where a drop-down menu offers many choices.  Tic the Preview Effect box to check the results.

The Pan/Zoom (Ken Burns) effect is another option, where a start and end position can be programmed.

Zoom in or out to any area of the image (such as the nose in the above).  Just adjust the handles or use the numbers in the effects box.                                                     Also experiment with the SCALE and CROP effects.

Once the effect is set, click the SAVE icon on the effects toolbar and give it a name.  Your custom effect will be just another icon, at the bottom of the effects box.  You can also right-click another clip and APPLY LAST USED EFFECT.

Hi

Apply a zoom as Borate describes. Remember that you must have start position for your first rectangle and then an end position for your second rectangle. These are set with keyframes.

"........But why can't I just tell it to zoom one small portion of the entire video?...."

You can .....but this will involve using keyframes to essentially isolate the part of the video you want to zoom. Effects (including Zoom) only work on a single clip. If the clip is actually the entire video and your zoom is a tiny section of the video then you might need to split the video so as to isolate the area you want to zoom as a short clip.

As far as repeating a specifically set up effect,(like a particular Zoom) then once you have set it up you can click the blue cassette tab to Save as an effect chain template. Your effect will then be saved  to the Templates section of the effects list from where you can use it over and over again. You can animate your clip with most of the  Motion and Transforms effects..

Quite complex animations can be produced by applying several effects on the same clip.
