Photos and names

Each card represents one presenter. Click a person to inspect their appearance on the next screen. They have not been added to your video yet.

Search field at the top

Enter a name to find a presenter. To follow this example, search for “タエ” (Tae).

Categories below the search field

Select a category such as Business or Education and research to narrow the list. If you are unsure whom to choose, start with a category that suits the tone of your video.

Check The list order may differ from the example. For now, choose the appearance you want. You will listen to voice samples and choose a voice later in this guide.

You can now see the selected avatar more clearly. Choose its framing, then add it to the editor.

1. 1Where upper-body and full-body views are available, choose the framing you want. This lesson uses the upper-body view.
2. 2Select Confirm at the bottom right to add the avatar.

1. 1
   Action Click the “ava_1の音声” voice row.
2. 2

1. 1Select Preview to listen. To use another voice, select its row.
2. 2Review the language and speaking style, then select Use this voice at the bottom right.

↘Red arrows and white labels are guide annotations ＋ Enlarge with callouts

1. 1
   Action Click Play to audition the voice.
2. 2
   Action Click Use this voice.

With the voice selected, give the avatar a short line. First create the audio and listen to how it sounds.

1. 1In the text field at the bottom, enter “こんにちは。はじめての動画です。”
2. 2Select Add on the right and wait for the audio. A green speech clip appears on the voice row.

↘Red arrows and white labels are guide annotations ＋ Enlarge with callouts

1. 1
   Enter Type a short line here.
2. 2
   Action Click Add.

Check Play the audio to check the voice, pronunciation, pace and wording. Make any adjustments before generating the video. The avatar initially appears as a still image. This step creates audio, not the moving, talking-avatar video. Hearing speech while the presenter remains still is expected at this stage.

Once the audio sounds right, create the video of the avatar speaking. This is called generation and takes some time, so finish adjusting the line first.

1. 1Select Generate ungenerated clips in the toolbar.
2. 2Wait until the avatar clip says Preview generated. You can follow progress in Generation jobs at the bottom.

↘Red arrows and white labels are guide annotations ＋ Enlarge with callouts

1. 1
   Action Click Generate ungenerated clips.
2. 2
   Check After generation, the avatar clip will say Preview generated.

Check This generates avatar clips whose video is missing or needs updating after edits. It does not regenerate every clip that is already up to date. Creating the video of the avatar speaking takes time. Review the voice, pronunciation and wording in audio first, then generate the video to reduce repeated waits after edits.

When the video is ready, play it from the beginning. Checking the voice and mouth movement together completes your first basic editing workflow.

1. 1Click near the beginning of the timeline ruler to move playback back.
2. 2Press the triangular Play button on the left. Check that the avatar speaks the full line in your chosen voice, with its mouth moving.
3. 3Check Saved at the bottom. This completes the lesson.

↘Red arrows and white labels are guide annotations ＋ Enlarge with callouts

1. 1

2. 2
   Action Click the triangular Play button.
3. 3
   Check Check Saved.

Check If you hear no sound, check the preview and computer volume. When using a longer line, ensure the avatar remains visible for the full speech.
