How can I upload videos to Flickr using Uploadr? Flickr Uploadr on OS X scans the folders I selected, but it doesn't count the videos in that folder. If the folder doesn't contain any photos, it simply says:


  No photos


How do I get Uploadr to upload videos to Flickr?
Open the Uploadr app and click the about tab. Then click on the logo to make a hidden menu appear:



Click "Enable Video Upload" and that's it! You can now upload videos in the formats that Flickr supports.
