Event Video Aspect Ratio

Hi All,

I've inserted few short videos on a slide that should run automatically upon entering and just loops, I dont have the intention of maintaining its original ratio (Vids1.png), but when I previewed the slide it goes back to its original eventhough it has been modified and locked (Vids2.png). Can you please let me know if its really possible to do on Captivate Classic 11.8?

Thank you.
