Add an intro and outro to a video

Add intro, outro segments to videos via FastPix API for branding and engagement.

FastPix delivers consistent branding and higher viewer engagement by prepending and appending intro and outro segments to any on-demand video using introUrl and outroUrl fields in the create request, which produces a single merged asset with its own mediaId and playbackId. Add these fields at upload time for new media, or reference an existing mediaId to attach segments to content already in your library.


Prerequisites

  • A FastPix account with an active workspace (Activate your account)
  • Your Access Token ID and Secret Key from the FastPix dashboard
  • Public URLs for the base video, intro, and outro files (MP4 or other supported source formats)
  • Intro and outro files that match the base video frame rate, with a resolution greater than or equal to the base

Key terms

  • mediaId: the unique identifier FastPix assigns to every uploaded asset. FastPix generates a new mediaId each time you attach an intro or outro, even when the base video is existing media.
  • playbackId: the access-controlled identifier used to build the HLS playback URL at https://stream.fastpix.com/<playbackId>.m3u8.
  • accessPolicy: controls who can play the asset. Accepted values are public and private.
  • introUrl / outroUrl: URLs of the segments FastPix prepends and appends to the base video during transcoding.

Add intro and outro to new media

Use the Create media from URL or Upload media from device endpoint. Attach one or both segments on the same request that creates the asset.


Prepare the media URLs

Gather the URLs for the following files:

  • Base video: the main video content.
  • Intro video (optional): the segment that plays at the beginning.
  • Outro video (optional): the segment that plays at the end.

NOTE

Each source file must be encode-ready. Source quality determines the quality of every rendition FastPix generates.


Limits and constraints

  • The intro and outro resolutions must be greater than or equal to the base video resolution. FastPix does not support upscaling.
  • The frame rate of the intro and outro must match the base video frame rate.

Build the create-from-URL request

In the request body, set:

  • url to the base video URL.
  • introUrl to the intro video URL (optional).
  • outroUrl to the outro video URL (optional).

Important

Replace each URL in the examples with the actual path to your media files.

Add an intro and outro from the dashboard

To add an intro and outro from the dashboard, you need to:

  1. Add your media.
  2. Configure intro and outro in media settings.
  3. Review metadata and start the upload.

Add your media

  1. In the left navigation, go to Products > Video > Media.
  2. Click Add media to add your video using one of the following methods:
    • Upload from device: Drag and drop your file into the upload area, or click Browse to open your device’s file picker. Navigate to the video you want to upload, select it, and click Open.
    • Upload using video URL: Paste a public video URL into the Upload using video URL field and click Submit URL.

Configure intro and outro in media settings

  1. In the Media Settings panel, select Custom settings.
  2. Add the introUrl and outroUrl fields in the JSON configuration.
  3. Replace the introUrl and outroUrl values with the public URLs of your intro and outro videos.
  4. Click Continue.

Review metadata and start the upload

  1. In the Metadata panel, review the preview of your video along with the auto-populated fields.
  2. Optionally, edit the Media title, Creator ID, or Third party ID.
  3. When ready, click Start upload all media.

Add intro and outro to existing media

Call the Create media from URL endpoint and reference the existing mediaId in the url field.


NOTE

FastPix always creates a new asset when you attach an intro or outro to existing media. The original asset is unchanged.


Build the request

  • Base video: set url to fp_mediaId://{Media_Id} using the mediaId of the existing asset.
  • Intro video (optional): set introUrl to the intro URL.
  • Outro video (optional): set outroUrl to the outro URL.

Replace introUrl and outroUrl with the actual paths to your media files.

Track status with webhook events

FastPix emits dedicated webhook events when each segment finishes transcoding:


Design effective intros and outros

  • Keep them short: 5–10 seconds each is a common target for retention.
  • Match brand identity: reuse the same colors, logos, and fonts across assets so viewers recognize the sequence.
  • End with a call-to-action: the outro is the place to ask viewers to subscribe, follow, or open a linked resource.

Frequently asked questions

What happens if the intro or outro frame rate differs from the base video?

FastPix requires the frame rates to match. If they do not, the transcode fails or produces unstable output. Re-encode the intro or outro to match the base video frame rate before retrying.

Can I reuse the same intro and outro across many videos for branding automation?

Yes. Host the intro and outro on a stable URL and reference the same introUrl and outroUrl in every create-media request. This is the recommended pattern for branded intro outro reuse across a catalog.

Does attaching an intro or outro to existing media modify the original asset?

No. FastPix creates a new mediaId and playbackId for the combined output. The original asset remains unchanged and accessible under its original mediaId.

Why do I need separate webhooks for video.media.intro.ready and video.media.outro.ready?

FastPix encodes and attaches each segment independently, so each emits its own event. Wait for both events (when both segments are supplied) before treating the merged asset as complete.

Can I apply intros and outros in bulk?

Yes. Loop the Create media from URL endpoint over your source list and pass the same introUrl and outroUrl in every request. This is the programmatic equivalent of an intro outro maker for your catalog.
