Blurred screens

Hi, Marleen.

Thank you for reaching out!

If I understand correctly, your process is:

• Grab a screenshot with SnagIt
• Insert the image into Powerpoint
• Export the slides to PNG
• Insert the PNG images into Storyline

Have you attempted a few different methods, such as importing the ppt file or inserting the SnagIt screenshots directly into Storyline? 

You can also check out this article for the best practices when working with images:

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

I found a few discussions specific to using SnagIt with Storyline, but they don't mention Powerpoint as an intermediate application. Here is one example.

Let me know if this helps!
