Question About Video Ratio Size with Storyline

Hello Brian, 

Happy to help!

To address your inquiry, I recommend checking out this article:

• Storyline 360: Best Practices for High Quality Images and Videos

Since you'll be working mostly with videos, we recommend matching the resolution of the videos as closely as possible with the slide size of your course to retain the quality. If the PowerPoint presentation that you will be importing has a different slide value, this will be adjusted to scale when imported to Storyline 360. If you prefer to retain the resolution of the PowerPoint slides, consider matching this value as well with the slide size of your Storyline 360 course. Here's an article on importing PowerPoint content for your reference.
