Storyline low screenshot quality

Hello,

The rule of thumb with zooming in on images is to capture them at a higher resolution and then they will stand up to zooming in on them. An image that is at a lower resolution will quickly deteriorate in quality once it starts being blown up past its original size. (Vector graphics being the exception, which a screen capture would not be vector.) 

You may try looking at the settings of your screen capture software and set the resolution and screen size (raster) higher. For example, if your Storyline project is 1280 x 720 pixels and you need to zoom in on a website screenshot and display it on part of your Storyline slide, try to capture the website image at a higher size (such as 1920 x 1080 or higher) and see if you can set the resolution to a higher rate (such as 300 pixels). 

Again, capturing higher than you need will allow you to blow up an image and retain quality. Capturing at the same size or lower and then blowing up an image will decrease quality.
