You can increase the number of videos each member can upload to a maximum of 50 using the Plugins/Ray area of the Dolphin admin panel.

If you want to go over 50 video uploads per user in your dolphin community follow these simple steps.

Open:
/ray/modules/movie/xml/settings.xml

Find the following reference:

key=filesCount

Shortly after that (on the same line) you will see:

range=3:50

This is a from and to value (from 3 to 50) - change the 50 to the number of videos you will allow each user to upload to your dolpin community site.

Now open your Dolphin admin panel (plugins/ray/video) and increase the maximum in the proper text box.
