Dropstock
http://dropstock.io is a service that distribute your photos, videos and vectors from your Dropbox to any agency's FTP. It saves time and bandwidth uploading your stuff. Awhile ago we added a video support, which brought quite some technical challenges, especially when video uploads grew.
Two weeks ago we hit the new record with thousands of video uploads sized between 300 MB and 4 GB .. and added few more servers to manage videos and general uploads.
Welcome to try it out, if you haven't done it yet!
If you have ideas and suggestions how to further improve dropstock.io, we are looking forward to hear from you!
