Hi Katie,

If you're hosting your content on a servers, some servers do not have an associated MIME type to support MP4 files.  To correct this issue, add an MP4 MIME type to your server.  Here's how:

  1. Right-click the site in IIS and select Properties.
  2. Select the HTTP Headers Tab.
  3. Select File Types.
  4. Under the MIME Map section, select New Type.
  5. Type ".mp4" as the associated extension and "video/mpeg" as the content type.
  6. Click OK.

Your MP4 movies should now play when viewed from the server.  If you use a hosting company to host your files, it's best to check with them about adding MP4 as a supported MIME type.

Thanks Ashley, that's very helpful. I'll pass that along to the IT people. 

Before it goes up on the server, however, we're testing it through google drive. Would we avoid these MME problems if we tested through dropbox, or is there something I could do to google drive so it supports the files?

Hi Atilo,

When testing your content that you've published for web, you'll want to upload to a web server to test it as testing locally could cause you to encounter local security restrictions or elements of your content to fail.  If you need to test it and don't want to upload yet to a public web server, you may want to use some of the sites mentioned in the above link:

  • TempshareThis is a free service provided by Articulate for testing Storyline content.Note: Uploaded files will be deleted after 10 days.
  • Amazon S3: Amazon S3 offers free hosting with generous usage limits. If you go over your limit, you'll be charged a graduated fee.
  • Dropbox: Place your published output in the Public folder in your Dropbox account to share it with others.
  • Google Drive: Change the story.html file to index.html, and set the sharing permissions to PublicHere's how.
