zoom and pan (Ken Burns) for an image

Question

zoom and pan (Ken Burns) for an image

I have an image that I want to zoom and pan into that is 1 of several elements on a slide.

The image box must not move and must remain the same size, only the image must appear to pan and zoom a la Ken Burns effect.

I have tried magic moves, Action>Scale (which just scales the picture)

I read somewhere about building a layer mask, but can find no info on how this is done.

Any help in solving this problem is appreciated. I'd prefer not to do it in iMovie, as some seem to suggest

This effect is called picture in picture.

Place a rectangle shape on the slide and size it to cover the whole slide set colour and fill type as needed (this is the mask)

place a second rectangle shape on the slide, size it for that the image will be (this is the hole cutter)

select both rectangle shapes (shift click)

go to Format > Shapes and Lines > Exclude Shapes (a hole will be cut in the mask showing the background)

place the image on the slide, then roughly position and size to fit the hole

send the image to the lowermost layer (arrange > send to back)

fine adjust the size and position of the image

with the image selected, Inspector > Animate > Actions > Add an Effect: choose scale

I realize I should have mentioned it's Keynote 09. The Format > Shapes and Lines > Exclude Shapes is not a menu item.

I tried creating a custom mask in photoshop and exported it as a png hoping to use it as a mask (based on your suggestion) but we can't get that to work either.

Additional suggestions will be much appreciated! Feels so close!

Create the mask with 4 rectangle shapes instead. Position to show the background:

then group the shapes (Option Command G)

remove the lines on the shapes

then place the image on the slide and set the action as before:

I was almost there yesterday. I created black rectangles around the image and tried to figure out how to apply it as a mask, but that doesn't seem possible. I think being a photographer and used to image masking from black like in photoshop kept me from figuring this out sooner.

By using coloured rectangles replicating my background I was able to get almost 100% there. I lose the drop shadow on the image but by putting a transparent frame on the top layer I get most of the look back (just with some shadowing inside the box.)

Thank you for your invaluable advice. I got a fist bump from the Department manager!

To be absolutely clear, the rectangle shapes do not create a background, they create a mask.

The white in the screen grab is the background.

The image is positioned between the background and the mask.

Good to know this has worked for you.
