Want to request thumbnails every few seconds from a video? Choose the interval, then add '!' to the end of the integer. Add this to either your API call or use our web UI. XML below for reference:
<?xml version="1.0"?> <query> <format> <!-- Format fields --> <output>thumbnail</output> <time>[integer value]!</time> <width>[Width]</width> <height>[Size]</height> <!-- Destination fields --> </format> </query>
Don't forget to give the first file a name in the API call, and also a destination! Files will not generate or deliver if these two items are not specified.
