Sources

Introduction

Sources are File Objects with a kind of video, audio, or image.

They represent the files in your project that contain the actual content.

{
  "id": "file_abcdefgh1234",
  "object": "source",
  "kind": "video",
  "type": "video/mp4;codecs=avc1,mp4a",
  // ... other props
  "url": "https://you.ittybit.net/example/video.mp4",
  "ref": "original",
}

Media objects can contain one or more Sources.

{
  "id": "med_abcdefgh1234",
  "object": "media",
  "kind": "video",
  "files": [
    {
      "id": "file_abcdefgh1234",
      "object": "source",
      "kind": "video",
      "type": "video/mp4;codecs=avc1,mp4a",
      "url": "https://you.ittybit.net/example/video.mp4",
      "ref": "original",
    },
    {
      "id": "file_abcdefgh5678",
      "object": "source",
      "kind": "video",
      "type": "video/webm;codecs=vp9,opus",
      "url": "https://you.ittybit.net/example/video.webm",
      "ref": "webm",
    }
  ],
  // ... other props
}

Usage

At it's simplest, a source is what you'd pass to an <img>, <video>, or <audio> tag's src attribute.

<video src="https://you.ittybit.net/trailer.mp4" type="video/mp4">

In production projects, you'll usually want to provide multiple sources for a media object.

For example, you might want to generate a poster image for the video, which can be used to display a thumbnail or preview before playback begins.

<video poster="https://you.ittybit.net/example/poster.png">
  <source src="https://you.ittybit.net/example/video.mp4" type="video/mp4">
</video>

You might then want to provide a version of the video in the more efficient WEBM format for browsers that support it, and fallback to your MP4 version for browsers that don't.

<video poster="https://you.ittybit.net/example/poster.png">
  <source src="https://you.ittybit.net/example/video.webm" type="video/webm">
  <source src="https://you.ittybit.net/example/video.mp4" type="video/mp4">
</video>
