MRSS Feed vs RSS Feed: What's the Difference?

If you've started researching video distribution, you've probably encountered both "RSS feed" and "MRSS feed" used almost interchangeably. They're related formats, but they serve fundamentally different purposes — and using the wrong one for video distribution can get your content rejected by platforms before a human even reviews it.

Here's the complete breakdown of what separates the two, why MRSS exists, and when each format is appropriate.

What Is an RSS Feed?

RSS (Really Simple Syndication) was created in the late 1990s as a way to publish frequently updated content — blog posts, news articles, podcast episodes — in a standardized XML format that any reader could parse. The format gained widespread adoption because it gave publishers a single, platform-agnostic way to broadcast new content to subscribers and aggregators.

The core RSS item looks like this:

<item>
  <title>My Article Title</title>
  <link>https://example.com/article</link>
  <description>A summary of the article.</description>
  <pubDate>Mon, 14 Apr 2026 10:00:00 +0000</pubDate>
  <enclosure url="https://example.com/episode.mp3"
             type="audio/mpeg"
             length="45231200"/>
</item>

The <enclosure> element is RSS's way of attaching a media file — typically an MP3 for podcasts. It handles one file per item, stores only the URL, MIME type, and file size, and carries no metadata about the media itself: no duration, no thumbnail, no resolution, no category.

That limitation matters enormously for video.

What Is an MRSS Feed?

MRSS — Media RSS — is an extension of the RSS 2.0 specification created by Yahoo in 2004 to handle rich media content. It adds a dedicated XML namespace (xmlns:media="http://search.yahoo.com/mrss/") that unlocks a full set of media-specific elements missing from standard RSS.

Where RSS has <enclosure> with three attributes, MRSS has <media:content> with dozens. A typical MRSS item looks like this:

<item>
  <title>My Video Title</title>
  <link>https://example.com/video</link>
  <pubDate>Mon, 14 Apr 2026 10:00:00 +0000</pubDate>
  <media:content
    url="https://cdn.example.com/video.mp4"
    type="video/mp4"
    medium="video"
    duration="183"
    width="1920"
    height="1080"
    bitrate="4500"
    fileSize="102400000"/>
  <media:thumbnail
    url="https://cdn.example.com/thumb.jpg"
    width="1280"
    height="720"/>
  <media:title>My Video Title</media:title>
  <media:description>Full description of the video content.</media:description>
  <media:category>News/Technology</media:category>
  <media:rating scheme="urn:mpaa">g</media:rating>
</item>

The difference is structural. MRSS was purpose-built for the metadata that video distribution platforms actually need to ingest, display, and monetize video content.

RSS vs MRSS: A Direct Comparison

When to Use RSS

Standard RSS remains the right format for podcast distribution. Every major podcast platform — Apple Podcasts, Spotify, iHeartRadio, Amazon Music — accepts RSS with <enclosure> for audio files. Most also accept iTunes-namespace extensions (xmlns:itunes) for podcast-specific metadata like episode type, season, and explicit flags.

If you're distributing audio-only content, or syndicating articles and blog posts to news readers, standard RSS is appropriate. It's simpler, universally supported, and sufficient for the use case.

When to Use MRSS

MRSS is required whenever a platform needs to display, play, or ingest video with rich metadata. This includes:

• News video platforms: MSN Video and Yahoo News Video both require MRSS with thumbnail URLs, duration, and category taxonomy
• Connected TV: Amazon Fire TV, Roku, Samsung TV+, and Plex all use MRSS (or a variant of it) to power their content directories
• Digital signage: BrightSign, ScreenCloud, and similar platforms use MRSS to pull video playlists
• Video aggregators: Platforms that index or redistribute video content need the full metadata set to properly categorize and display your content
• Content syndication networks: Any network distributing your video to third-party publishers will use MRSS to carry the complete content package

Attempting to use a standard RSS feed with a video enclosure for these platforms will typically result in the feed failing validation or being rejected during the partner onboarding process. The platforms need the thumbnail to render a preview card, the duration to build their UI, and the category to place your content correctly in their directory.

The Practical Difference for Video Publishers

The most important practical distinction is this: an RSS feed with a video file attached tells a platform "here is a video file." An MRSS feed tells a platform "here is a video, it's 3 minutes and 4 seconds long, it's 1920×1080, here's the thumbnail at 1280×720, it's rated G, it belongs in the News/Technology category, and here are the rights restrictions."

That information is what allows a platform to show your content in a grid without downloading it, apply content filters, generate ad break positions based on duration, and route it to the right section of their directory.

Can You Use RSS for Video Podcasts?

Yes — and this is a valid use case. If you're publishing video content to podcast directories (Apple Podcasts, Spotify, YouTube Podcasts), you can use RSS with an <enclosure> pointing to an MP4 file. Apple Podcasts supports video RSS feeds with the iTunes namespace. For this use case, standard RSS is standard.

But podcast video distribution is distinct from news video syndication or CTV distribution. The destinations, the requirements, and the metadata schema are different. If you want your video on MSN, Yahoo Video, or a Fire TV channel, you need MRSS.

How VideoNest Handles This

VideoNest automatically generates MRSS feeds that meet each platform's specific requirements. When you create a feed in VideoNest, the system populates all required media:content attributes, generates thumbnail URLs at correct dimensions, formats duration in seconds, and applies the right category taxonomy for your target platform — whether that's MSN Video's partner hub spec, Yahoo's RSS Advisory Board format, or Fire TV's content schema.

You don't manage the XML directly. You configure the feed settings, and VideoNest produces a compliant MRSS URL you submit to your distribution partners.

VideoNest supports podcast RSS distribution separately — the platform can generate both MRSS feeds for video platforms and standard RSS with <enclosure> for podcast directories from the same content library.
