Edit source clips (B-roll) in avatar videos


About

Some avatar video projects include source clips (B-roll) behind the avatar to support the narration. A source clip can be a video clip or a slide from a presentation.

You can manage source clips directly from the editor, including adding and replacing clips, repositioning video clips, changing slides, and hiding clips from scenes.

Open a project

  1. Select My Avatar Videos from the user menu.
  2. The My Avatar Videos page opens.

    Projects are displayed in a grid sorted by the most recently updated.

  3. Find the project, click the three dots, and select Edit project.
  4. The project opens in the editor.

Manage source clips

Scenes with a source clip display a media thumbnail and media controls. If the clip is a video, you can reposition it within the original video to better match the narration.

You manage source clips from the Media panel:

  1. Find the scene.
  2. Open the Media panel in one of the following ways:
    • Click the gear icon on the media thumbnail.
    • Click Media on the upper right toolbar.

The Media panel opens.

From the Media panel, you can:

  • If a video clip is shorter than the scene narration, it loops automatically.
  • If a video clip is longer than the scene narration, it's trimmed automatically.

Edit clip selection

In the Media panel, click Edit clip selection.

The clip editor opens.

The clip editor includes:

  • a video preview player
  • playback controls
  • a timeline
  • zoom controls
  • the selected clip range

Reposition the clip

You can reposition the selected clip within the source video, but you can't manually change the clip duration.

  1. Drag the highlighted clip range left or right on the timeline.
  2. You can also click a location on the timeline to move the selected clip range directly to that position. The preview updates automatically while you reposition the clip.

  3. Click Change clip to save the new clip position.

Change the timeline view

The clip editor opens in Zoom view by default, focused on the selected clip range.

Click Full video to display the entire source video timeline.

Click Zoom to focus on the selected clip range again.

Preview the clip

Click the play button to preview the selected clip.

Playback stops automatically at the end of the selected clip range.

Add a video clip

When a scene has no source clip, you can add a video clip.

Only captioned video entries can be used as source videos. Entries without captions don't appear in the media selector.

  1. Open the Media panel and select Add video clip.
  2. The selector window opens.

  3. Find the video you want and click Select.
  4. The clip editor opens in Full video view and shows the scene duration. The clip range starts at the beginning of the video.

  5. Drag the clip range to the part of the video you want to use.
  6. You can click Zoom to focus on the clip range and refine the position.

  7. Click Add clip to scene.

The video clip is added to the scene.

Add a slide

When a scene has no source clip, you can add a slide from a presentation.

Slides use Fill sizing. Presentation slides that aren't 16:9 are automatically cropped to fill the video frame.

  1. Open the Media panel and select Add a slide.
  2. The Select a presentation window opens and displays available files (PPT/PPTX).

    You can search for a presentation or upload a new one.

  3. Select the presentation you want.
  4. The Select a slide window opens.

  5. Click the slide you want.
  6. The slide is added, and the scene preview and timeline thumbnail update automatically.

Change a slide

  1. Open the Media panel and click Change slide.
  2. The Select a slide window opens for the current presentation.

  3. Select a different slide.
  4. The selected slide replaces the current slide, and the scene preview and timeline thumbnail update automatically.

Replace a source clip

You can replace the current source clip with a different video clip or presentation slide.

  • Video clips - Only captioned video entries can be used as source videos. Entries without captions don't appear in the source selector.
  • Slides - Only presentation files (PPT/PPTX) are displayed in the source selector.
  1. In the Media panel, click Select a different media, and then click one of the following:
    • Select a video clip
    • Select a slide
  2. The source selection window opens.

  3. Find the replacement and click Select.

The selected clip or slide replaces the current source clip for the scene.

Reposition the replacement video clip

If you replace the source clip with a video clip, the clip editor opens so you can reposition the clip before adding it to the scene.

  1. Drag the selected clip range to reposition the clip within the new source video.
  2. You can then click Zoom to focus on the selected clip range and refine the clip position.

  3. Click Add clip to scene.

The source clip is replaced.

Hide a source clip

Hide the source clip when you want the scene to display only the avatar.

  1. Open the Media panel.
  2. Click Hide from scene.

The source clip is removed from the scene preview, and the scene displays only the avatar narration.
