In this topic you will learn how to create a video clip using the Live module.

 

The Live module provides the ability to create video clips from completed events. Clips can also be created while a live event is in progress. There are several reasons you might want to create a clip:

  • To create a short, teaser clip that can be posted to social media
  • To limit the length of a video that you want to post (most platforms limit the length of videos)
  • You have found that shorter videos perform better on social media

Notes:

  • Clips can only be created within 24 hours of the event end. Afterwards, the Create Clip button will be disabled. If the event is longer than 24 hours, only the last 24 hours are clippable.

  • For Static Entry Point (recurring) streams: If during the 24 hours after a stream, the stream is re-activated with a 2nd stream, the clipping will only be available for the content of the 2nd stream. The 1st stream will be cleared at that point, and there is no way to create create clips from it anymore, even if it is under 24 hours after the stream was deactivated.

  • Clips will be frame-accurate provided that the encoder is sending SMPTE timecodes for the stream.
  • Clips with a start time less than 10 seconds into the stream cannot be created.
  • Media sharing will fail for videos created by clipping Live streams.

To open the clip editor, open the Live module, click on an event name and then click Create Clip. The clip editor will open.

Note that all times in the clipping interface are based around the UTC time that the video data was received by Brightcove. This is a necessary adjustment to account for streams that have exceeded the VOD window (run more than 24 hours). When a video has exceeded that window, the time we get back from the player can no longer reliably be used to generate clips.

The clip editor is organized as follows:

Creating a clip

When creating clips, the highest quality rendition from the selected Live Ingest Profile is used as the source for the clip. The default uploading ingest profile for the account is used when creating renditions for the clip. Clips are segment accurate only.

Follow these steps to create a clip.

  1. Using the clipping buttons or shortcut keys, set the start and end points for the clip.
  2. Click Save Clip.
  3. Enter the clip video properties.
    • Clip Name - Name of the clip
    • Short Description - Description of the clip
    • Tags - Tags to associate with the clip
    • Reference ID - Reference ID to assign to the clip

    Any required custom fields will also be displayed.

  4. Click Create Clip. The transcoding process for the clip will begin. Clips are transcoded using the default ingest profile for the account.

A list of all clips will appear below the clip editor. Clicking the Clip Name will open the clip in the Media module in another browser tab. Click Publish to Social to open the clip in the social module to publish it to a social media account. For information on publishing videos using the Social module, see Publishing Videos to Social Media Platforms.

Preview player

The preview player is used to preview the clip. When the event is in progress and the clip editor is opened, the clip will begin to play from the "safe live point" which is approximately 3 segments before the end. Note that not all browsers support autoplay.

Playback control buttons

The playback control buttons are used to control to playback of the clip inside of the preview player.

Button Description
Starts video playback at the beginning of the source video
Jumps the playhead back 15 seconds
Starts video playback from the playhead position
Jumps the playhead forward 15 seconds
 

Clip time

The clip time displays the current UTC time for the playhead and the clippable time. Clicking on the UTC link will switch to the local time display.

Clipping buttons

The clipping buttons are used to clip the desired portion of the source video.

Button Description
Jumps to cue in point of the video
Sets the starting point of the clip. The start point can also be set by dragging the handle at the beginning of the focus timeline.
Sets the ending point of the clip. The end point can also be set by dragging the handle at the end of the focus timeline.
Jumps to the cue out point of the video

The cue in and cue out points are the start and end of a clip. Each of these points is represented on the focus timeline with a draggable handle, and the time between the points is filled-in green. The points are also represented in the context timeline as the left and right edges of the green rectangle indicating the clip space.

Preview clip

Click the preview clip button to play the clip. The button will display the current length of the clip.

Playhead

The playhead is an indicator of where in time the player is playing. The playhead is represented in the focus timeline by a red line with a white circle on top and with a red vertical line in the context timeline.

On the focus timeline, the playhead may be dragged to scrub through the video. Double-clicking on the focus timeline will move the playhead to that point. The playhead can also be used to set cue in and cue out points using the cue-in/cue-out buttons or by using the keyboard shortcuts.
