I think it would be great if you could also use the Pan And Zoom feature with videos! I most of the time want to zoom in in a video but am sadly not able too cause it's not an option 😕
Sorry for the disappointment. You can add this feature request on Rush UserVoice: https://adobe-video.uservoice.com/forums/916423-premiere-rush
Let us know if you have any questions.
Currently that's something you need to use Premiere Pro for.
Fortunately, you can open your Rush project in Premiere Pro and continue from there. Of course, it requires that your Creative Cloud subscription includes Premiere Pro.
Since you mentioned zooming in, that's better to do in After Effects as you can take advantage of its Detail-preserving Upscale effect for better image quatily as you zoom in.
