BEFORE YOU START
Before you start
Prepare a topic, two roles and a short script, plus a .pptx file if you have slides. A useful structure is question, explanation, then a recap by the questioner.
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.
Choose the route that fits your conversation
For a flexible interview or Q&A, start with Create from scratch and follow steps 2–4. For a two-presenter slide explanation, start with Create from PowerPoint and use steps 5–7. Both routes finish with the same review.
- Check Explain slides as a duo
Track editor: add two people to a blank project
Use Add avatar for the first presenter, then again for the second. Place them on opposite sides with room for faces and captions. Check the avatar association for each speech track and choose their voices.
- Action Click a presenter (Tae in this example).
- Assign roles first
- Choose the questioner and explainer first. Naming tracks by role or person makes editing easier.
- Full-body and upper-body
- Choose from the avatar’s available appearances. Check the feet for full-body presenters and the crop boundary for upper-body presenters, keeping slide text clear.
Track editor: add short lines to the correct speaker
Select A’s speech track for “What should I check first?”, B’s for “Check the name and reservation time on the reception screen,” then A’s for “So, the name and time.” Add and audition one question or answer at a time.
- Check Enabled and locked
- Enter Assign the speaker
Track editor: arrange the exchange and listening shots
Arrange speech clips in sequence and avoid overlap unless simultaneous speech is intentional. Review pauses and ensure each avatar range contains its complete speech. Keep the listener visible where desired, using a calm expression or restrained nod.
- Action Select the avatar and speech clips separately.
- Check Select the speaker track before using the voice and text controls.
- Use editable boundaries
- Split speech and avatar clips into short meaningful sections, keeping complete speech and surrounding silence within the avatar range. See Editing tips.
- Cut to the other presenter
- Adjust position, size and visible intervals. Check the picture arrangement separately from the assignment of speech to people.
PowerPoint: import slides and choose Two-person dialogue
Import the slides with language and target duration, then choose “2 人の掛け合い” (Two-person dialogue) in template selection. Review the slide above, presenters on the sides and captions between them for readability.
- Check Explain slides as a duo
PowerPoint: choose the host and guest separately
Choose Presenter A (host), followed by Presenter B (guest). Select different people for their roles and check each voice. Use Play to audition and Custom to change the voice settings.
- Check Choose presenter B
- Check Check each voice
PowerPoint: review the exchange on each slide
In Slides and script, inspect each line’s speaker and dialogue. Edit or add lines so the intended person asks and answers; switch the speaker where needed and audition each line. Keep questions and answers concise rather than having two people read the slide aloud. See the studio reference for emphasis and separate caption/narration text.
- Action Add dialogue to this slide.
- Action Use Add emphasis to highlight slide content.
- Action Details opens speed, fine adjustment and caption wording.
- Continue in the track editor
- After refining the script, use the transfer workflow to continue in the MotionVox editor. Check both presenters, speech, captions and emphasis. Before transferring again, check its effect on existing edits.
Both routes: check speech before generating the talking video
Check both voices, pronunciation and conversational pacing first. Generate the required avatar clips, then review the speaker’s mouth, listener’s expression, captions and slides together. Export the MP4 and check the saved video too.
- Action Click Generate ungenerated clips.
- Check After generation, the avatar clip will say Preview generated.
BEFORE YOU FINISH
One final check.
Check for swapped voices, unintended overlapping speech and a listener disappearing at an awkward moment.
