TwitVid Telly API - 413 Request Entity Too Large when uploading video


I am able to upload short videos to TwitVid/Telly using their API from a desktop application. When I try to upload anything over 1MB…which is still not very large, I get a 413 Request Entity Too Large error. The only info I can find about this error is how to configure your Nginx server, but nothing on what to do as a user of an API. I am using a Chilkat Http Active X control to upload via a desktop application.
