A Pop-up launches when you visit certain websites. Their main aim is to try to catch the visitors attention and to bring something to their notice. As the plugin name suggests, it will help you pop-up videos on your site.
Currently the plugin supports only youtube videos. I hope to extent support for vimeo soon by the next version upgrade.
<h3>When is the pop-up triggered?</h3>
The pop-up is triggered when the user scrolls to the bottom of the page (footer). This makes sure user has least distractions on the site, only when he reaches to the end, he gets the pop-up. This makes its less annoying for visitors. However future version may provide customization over trigger.
<h3>How to setup the plugin?</h3>
<ul>
<li>Once you install the plugin to your site, you need to activate it. After the plugin is activated, you can find ‘Video Popup’ settings in your dashboard left pane.</li>
<li>Click on the ‘Video Popup’ setting button to get the settings page.</li>
<li>By default the height is 325px and width is 420px. You can however define your own custom dimensions.</li>
</ul>

The standard WordPress Thickbox can size images dynamically to fit the user’s browser window. But what about video or other types of media. 
This plugin allows any content to be shown in a thickbox that is sized dynamically to fit the browsers window. While a popup can be initiated 
from a link like the standard Thickbox, the plugin is intended to be used as a shortcode because more options to control the display can be supported. 
A shortcode builder form is provided so you don’t need to remember all options can get the names right.
<h4>Features</h4>
Dynamically sized content
<ul>
<li>Images, videos and even HTML pages can be dynamically sized to fit the user’s browser window</li>
<li>Optionally setup discrete sizes to show your content if it is seen best at specific resolutions</li>
</ul>
Uses the HTML5 tag to display videos
<ul>
<li>Specify urls to different video formats so more browsers will be able to see your videos</li>
<li>Falls back to FlowPlayer if a browser does not support the video tag or cannot display the formats you provide</li>
</ul>
Includes a shortcode builder
<ul>
<li>No need to remember all the options available</li>
<li>Fill in the blanks and the shortcode is created ready to paste into posts and pages</li>
</ul>
No conflict with Thickbox
The plugin does not use or rely upon the standard Thickbox implementation. Use both if that meets your needs.
