Hi!
It looks like you’re referring to the ‘Universal Results’ panel which shows up on the right hand side of the Keyword Rankings tab here.
As you may be aware, this panel shows you if your site is ranking for that keyword in the universal results.
Universal results are displayed in SERPs in the form of a pack of images, local results or video results, which is determined by the search engine, in this case Google.
So when I search for 'Rank Fishkin' I see this pack of images in the results, here.
Ok, back to Moz Analytics, and how you can explore your universal results further
In my campaign, screengrabbed here, you’ll see that for the keywords I’m tracking in this report 6 have image results and 1 of those results is for my site! There are no local and no video results in this particular report.
You can dig deeper into your universal results by scrolling down to your report and hovering over the camera (for images), places marker (for local), or film camera (for videos).
This will show you more information about the results and how your site is performing, this is what is looks like when you hover over the icon.
There’s some additional help on the keyword ranking guide (click on ‘More Help’ on the top right) here:

I know that you’ve asked specifically about how you can work on your video performance so I’ve also dug up some additional reading.
