At blip.tv we're focused on being the best home for high quality, original episodic web series. To that end, we have focused on making our upload process as easy and fool-proof as possible. For a number of years we've permitted the upload of non-video formats, but beginning December 20th, 2011 we will be turning off the ability to upload all audio-only formats, including MP3.
Pro accounts will still have the ability to create MP3 conversions from their source video files, but direct MP3 uploads will no longer be allowed. If you are uploading an audio only podcast, we strongly recommend using a more appropriate platform such as Libsyn or Podbean.
Please note that you must move your content to your new provider before using our iTunes MP3 RSS Redirect Tool. Our tool will only move your current subscribers to your new feed in iTunes, it will not move your actual content. Most MP3 podcast hosts offer their own tools for moving your content to their service, so please consult their support documentation for further assistance.
MP3 files currently hosted on blip.tv are currently scheduled to be removed from our servers in July 2012.
