Hi! Is there a way to store mp4 videos in imagevault and easily display them on the site?
There is a YouTube connector that takes any video you upload and puts it on YouTube, then you get a media reference of that video in ImageVault that you can use on your site (it will display a YouTube player). It's important to note that this is just a proof of concept connector and it does not store the video itself in ImageVault, it would be stored and published on YouTube and ImageVault would keep a reference to the YouTube content.
The YouTube connector is documented here: http://imagevault.se/en/documentation/api-documentation/?page=plug-ins/youtube/index.html
In upcoming releases we have plans to add direct video support to ImageVault as well.
