The motion keyframes are completely separate from the ones controlling things like size and rotation of the main object, so you'll need to set them individually in the Motion and Properties tabs.

Set the Scale keyframes at the start of the clip so it's at the small size you want, then duplicate that keyframe where you want the clip to start growing. Set the ending Scale keyframe to have your image grow to full size.

That sequence will then occur along whichever motion track you choose, modify or create.

Hi. Yes I noticed that before I wasn't setting the scale key frames

Once I clicked on scale where all the automatice postion key frames were, the image stayed small the way I wanted until I created a new key frame for position and scale and then I enlarged it to full screen and it worked

I also wanted to ask if there are more varieties of the slideshow creator available

there are some good ones in there like gallery, film, post card

I wonder if we can download any others or other ideas on how to create our own 10 second slide show
