Problem with the screen recording in Articulate. HELP!

Hi everybody. Ok, there is a big problem which I am facing. 😬

1. Screen recording I have. Screen recording as simulation was done by me by selecting an 'x' size of screen size, which is never a trouble maker.
2. Now I put that same recording as simulation where slide by slide test mode was selected by me.
3. Now my smart colleague chose to change the screen size to 720x540. I had kept it 960x540 earlier. Now she wants me to simply copy and paste the slide as shown in below screenshots for ref.
4. I 'simply' copy it and by doing ctrl+v I could duplicate the slide.😒 (Note: this is happening for any slide that I try to duplicate). 
5. As shown below in the SS, the recording size or ratio gets distorted and goes out of the slide size or canvas.
6. Since its a recording, I get no option to fix this by adjusting the edges of it like how we increase or decrease the picture or image size. It 'simply' doesn't allow me to have a clean duplicate file or slide of the ones created. 

Therefore, I seek for help from anyone  who could do some miracle. Else, I have to redo everything or to think about some something else. Because these things aren't in my control. Watch the SS attached carefully. Thanks. 😇
