Q: What’s the difference between storing files on Amazon S3 and serving it using the S3MediaVault.com plugin, as opposed to hosting the files right on your web site and having DAP serve them directly?

A: If you have a large amount of video, audio and other files, then a lot of people viewing and downloading them from your site (if they are stored on your site itself) will use up a lot of resources on your server – like site loading time, server memory, server bandwidth, etc – and your site could slow down considerably.

Plus of course, there are also bandwidth charges that your host will charge you with for all of those downloads, which are usually not very cheap.

Instead, if the files are stored on Amazon S3, then you don’t have to worry about your site slowing down, or you using up too much bandwidth and getting slapped with huge bandwidth fees, because the files are being served from Amazon’s huge S3 servers which have tons more resources and speed compared to your web host. Plus in the long run, the bandwidth is also going to be cheaper on S3 compared to your host.

And don’t put too much faith in your web host’s “Unlimited Bandwidth” clause, because if you read the fine-print carefully, you’ll see that as per their TOS, if you consume large amounts of bandwidth and use too much of the server resources, this could cause other web sites (belonging to others) on the same server to slow down and have a degrade in performance. And they could consider this abuse of their TOS, and could either slap you with huge bandwidth or server utilization fees, or even ask you to take your web site elsewhere because you’re causing issues for other site owners on the same server.

There are many ways in which you can protect videos.

Case 1: The video file is stored on your web site

By default, DAP can only protect files that are stored on the same web site where DAP is installed.

So if you install DAP on YourSite.com , then your files must also be located on YourSite.com. DAP installed on YourSite.com cannot protect files (.mp4, .mp3, .html, .pdf, .doc) that are stored on AnotherSite.com.

So assuming the files are stored on the same site as DAP, you can (and should) protect both the actual video file, as well as the blog post or page in which the embed-code for your video is published, by adding both to a Product.

This gives you 2 levels of protection for your videos:

Level 1: The blog post or page containing the video player code, itself is accessible only by authorized members.
Level 2: When an authorized user gets legitimate access to the page where the video is published (because they’re a paying member, say), even if they try to do a view source and figure out the location of the video (eg., http://yoursite.com/videos/howtovideo1.mp4) , and pass it around by email to their friends (or post the link in an online forum), their friends still can’t view the video, because the video link itself is protected by DAP.

If you have some text that you want the casual visitor (and Google) to read, but wish to protect only the video, then you could turn Sneak-Peek on (in Setup > Config > Advanced), insert a WordPress more tag (<!–more–>) into your post just where you want the content to start being protected, and put the video player’s embed code after the more tag.

Case 2: Video file is stored on Amazon S3

The only 3rd-party-stored video files that DAP can protect at this time are videos (and other files) that are stored on Amazon S3. DAP cannot do this by itself, but uses a special WordPress plugin called S3MediaVault.com , which is a plugin we developed specifically to make Amazon S3 videos play in your WordPress blog posts/pages. So again you get 2 levels of protection for your videos…

Level 1: DAP protects the post/page where the special S3MV video player code is embedded
Level 2: The S3MediaVault plugin makes sure that even if someone tried to do a view source and figure out the actual link to your Amazon S3 video, they still won’t be able to view the video.

WARNING: Video stored on other 3rd party video sites

DAP cannot protect, say, videos that are embedded from other 3rd party web sites like YouTube or Hulu. Of course, DAP can always protect the blog post or page itself that contains the video, but once an authorized user gets valid access to that blog page, they can see that it is a YouTube video (say), and then pass that YouTube video link to their friends, in which case DAP cannot protect that external YouTube video link.
