BEFORE YOU START
Before you start
Open a project with short speech clips. If there is still one long passage, first see the sentence-splitting guide. Save a copy before making substantial changes to clip boundaries.
Screenshots show actual sample projects. Your interface may vary with your plan and updates. Instructions describe desktop browser operation; this guide can also be read on a phone.
Understand the avatar range affected by a change
When one long avatar clip contains several speech clips, changing one line requires that avatar clip’s video range to render again. Short speech clips alone do not shrink the video range if the avatar remains one long clip. The diagram illustrates a change to the middle of three lines.
Check This reduces the video range to regenerate. Actual waiting time depends on content and processing conditions; the illustrated ratio is not a guaranteed speedup.
Split the avatar while containing each complete speech clip
Match the avatar video to your shorter speech clips. Keep each complete line inside its avatar clip so the presenter does not disappear midway through it.
Check the start and end of each resulting speech clip, including its leading and trailing silence. Keep the whole speech clip inside an avatar clip. Place the playhead between speech clips, select the avatar clip and use Split (Ctrl+K) in the toolbar. Adjust edges if needed. Do not cut the avatar in the middle of speech; check both sides of the boundary for disappearing presenters or interrupted mouth movement.
- Action Select the avatar video clip.
- Action Select the speech clip to edit dialogue.
Check Sentence splitting and splitting at a time position are different operations. For avatar splits, keep the playhead inside the clip. Splitting is unavailable at an edge or when a resulting piece is too short.
Regenerate the affected range and play across its boundaries
After checking the changed audio, select the corresponding avatar clip and choose Generate this clip. Use Generate ungenerated clips for multiple pending updates. Immediately after first splitting an avatar, its resulting clips may need generation. Once the boundaries are established, later edits to one speech clip can affect a smaller range.
- Action Click Generate ungenerated clips.
- Check After generation, the avatar clip will say Preview generated.
Check If a revised line extends beyond its boundary, adjust the avatar range first. Changes to shared voices or expressions can also require other clips to regenerate.
BEFORE YOU FINISH
One final check.
Does each avatar range contain its full speech clip and surrounding silence? Play across every cut to check audio, mouth movement, presenter visibility and captions, then save.
