Understand tracks, their roles and settings

A track runs rightward from its name; each colored interval is a clip. Clips active at the same time combine into the picture and sound. The time a presenter is visible and the time they speak are edited separately.

   Action Select the speech clip to edit dialogue.

Click the track name

Click the name on the left to inspect settings for the entire track on the right.

Click a clip

Click a colored interval for that clip’s text, duration and appearance. Its scope differs from track-wide settings.

The avatar track defines when the person is visible; the speech track defines when they speak. A visible person needs dialogue to speak, and the avatar range must cover the speech to generate the talking image.

Whose dialogue is this?

Select the speech track and check the assigned avatar here. Renaming a row or moving it next to another does not change its association.

Voice, level and text

Select the speech clip to inspect these settings rather than looking only at the track properties.

Media rows hold backgrounds, photos, videos and shapes. Headings and captions also have their own clips, durations and styles. Names such as Background and Caption band describe the purpose; inspect the clip type as well.

Layer order

Move up/front or down/back to change layering. Keep backgrounds behind people and captions. Layer order is different from the order of spoken lines.

Linked captions

Distinguish captions linked to speech from independently written headings. After editing captions directly, check whether they remain linked.

Head motion controls actions such as nodding, expression clips add reactions, base expression sets the sustained face and base gaze sets eye direction. Unlike moving a presenter across the screen, these controls are associated with a specific avatar.

Target avatar

Check the association in Properties. In a dialogue, manage each person’s expression and motion separately.

Track-specific baselines

Base-expression tracks have a family and baseline for gaps; base-gaze tracks have a baseline direction. See the expression and gaze guide.

Select the track name to find Enabled and Locked. Lock a background you do not want to accidentally move; disable a track when you want to compare the composition without it.

Enabled

Disabled tracks are excluded from preview, export and generation. This is not just an editing-view visibility preference.

Locked

Locking prevents accidental selection and dragging in the preview. It does not remove the track from the resulting video.

Review presenter A with A’s speech and expression, then do the same for B. Verify the assigned person and audition lines to avoid putting A’s dialogue on B’s track. Use avatar clips that contain complete short speech clips to keep regeneration small.
