How do I zoom into an area in one clip and zoom out in another while controlling the magnifiaction?

I have been trying to use cross zoom in various configurations to achieving what I want as follows:

ending at cut or starting at cut or both
also using the sliders and position targets

I can control the magnification of the zoom in for the first clip using the cross zoom ending at the cut. I tried to zoom out in the following clip to start at the same magnification as the end of the preceding clip but I found I have not been able to use two cross zooms ending and starting at the same point.

Am I am missing something?

Use the Effects Control> Motion >Scale parameters ...and key frames... for each clip.

Please refer to my reply to Ann and provide more detail for how I can use the Scale parameter to do what I was intending with the Cross Zoom or otherwise.

Ah ha...

But first be aware...a Zoom of that amount will seriously degrade the images!!!

You need Scale and Position Key Frames to align the images.

Select the 1st Clip

Effects Control>Motion> Scale & Position >"zoom to size andadkust position ...Key Frames ...over a duration of your choice at tail of clip.

Same again at head of 2nd (incoming) clip after you have aligned (scaled/positioned) the images as you wish.

Butt the shots with a hard cut effect for a trombone transition effect ....or over lap the shots more or less to achieve a softened transition with a Cross Dissolve or Opacity Key frames for max control.

Do you have an example to show of what you are trying to achieve.

Do the clips have sufficient handles to make the transition?

I may be able to provide a useful description of the two clips as follows:

The first clip shows a swimming pool from one side looking at a row of distant lounge chairs on the opposite side. The chairs are I/3rd from the top of the frame and approximately 1/11th the height of the frame. The second following clip shows the lounge chairs up close, approximately 5 times the size and at 1/3rd of the frame on the bottom left and extending to the right to a seated person about half way up the frame. As you may only need an ending and a beginning frame since here is no video zooming involved, I can convert to jpeg before sending if you prefer.

I enjoy a challenge and need the experience. Because there is a significant difference in height and position of the chairs in the two frames, I probably should abandon the zoom and use a cross dissolve.
