I find myself in a foreign place....
in my home, why does this happen:
Video Url: {{exercise.videos[0].url}}
It works correctly by displaying the video url... but:
<iframe src="http://fast.wistia.net/embed/iframe/{{exercise.videos[0].url}}"></iframe>
Only shows '{{exercise.videos[0].url}}' and not the same information as above?
The reason why src is not interpreted by AngularJS is because it does not recognize it. However, AngularJS does evaluate ng-src:
<iframe ng-src="http://fast.wistia.net/embed/iframe/{{exercise.videos[0].url}}"></iframe>
One issue to address is not with the iframe tag, but rather with the src attribute. To properly utilize an angular variable within a src attribute, it's essential to incorporate the ng-src directive.
<iframe ng-src="http://fast.wistia.net.embed.iframe/{{video.clip[0].url}}"></iframe>
Using angular brackets in the initial scenario is a convenient way to implement the ngBind directive, as it specifically focuses on altering the content of an element rather than serving as a all-encompassing text substitution tool within the template, a feature common in other template frameworks.
Strict Contextual Escaping is a security measure implemented in AngularJS to prevent cross-site scripting (XSS) attacks and clickjacking.
If you need more information, you can visit the following link:

The previous comments were accurate. You can utilize the ngSrc directive to bypass this restriction. However, you may need to inject the $sce module and employ the trustAsResourceUrl() method for it to function properly. Here's an example using a fiddle:
HTML:
<iframe ng-src="{{example.videos[0].url}}"></iframe>
JS:
$scope.example.videos = [{url:$sce.trustAsResourceUrl("http://fast.wistia.net/embed/iframe/someUrl.html")}];
