<summary>Advanced Templating Options</summary>
Crop specifies the region of the video frame to capture. <br/>
Location specifies the region within the template image where the cropped image will be placed. <br/>
Regions are given as pixel coordinates of the top-left and bottom-right corners. <br/>
Note that if the regions are different sizes, the image will be stretched. <br/>
Crop:
<input type="text" class="video-info-thumbnail-position" id="video-info-thumbnail-crop-0" />
<input type="text" class="video-info-thumbnail-position" id="video-info-thumbnail-crop-1" />
to
<input type="text" class="video-info-thumbnail-position" id="video-info-thumbnail-crop-2" />
<input type="text" class="video-info-thumbnail-position" id="video-info-thumbnail-crop-3" />
<br/>
Location:
<input type="text" class="video-info-thumbnail-position" id="video-info-thumbnail-location-0" />
<input type="text" class="video-info-thumbnail-position" id="video-info-thumbnail-location-1" />
