BEFORE YOU START

Before you start

Open the project you want to work on. If you are new, start with the first-video guide before exploring these controls.

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.

PART01

Review audio, then generate the video you need

The avatar initially appears still. Adding dialogue creates audio; generating the talking video is a separate step. Video generation takes time, so review the voice, pronunciation, pace and wording first. After editing audio or expression, check the affected avatar clips’ generation state.

  1. Action Click Generate ungenerated clips.
  2. Check After generation, the avatar clip will say Preview generated.
After adding speech, generate the video preview. The product screenshot is in Japanese; the instructions explain the controls.
Generate this clip
To preview one clip, select the avatar clip and use this button. It is unavailable when the clip has no renderable speech, expression or head motion, or is already up to date.
Generate pending
Generates missing or outdated avatar clips together, leaving up-to-date clips unchanged. Check Display language. If a translated version needs translation or audio updates, those are processed first.
Generated / needs generation
Describes clip readiness, not whether the project is saved.
PART02

Check progress in Generation jobs

Open Generation jobs at the bottom to inspect progress. Read queued/running/failed states before submitting another request.

  1. Action Open Generation jobs.
Generation jobs at the lower left of the editor: open it to check rendering progress. The product screenshot is in Japanese; the instructions explain the controls.
Generation jobs
Opens the job list. For failures, check the target and reported reason.
Review playback
Check the actual mouth movement, sound and caption ending, not only the status badge.
PART03

Export to MP4

Check Display language, then choose Export or Output → Export video. Read the confirmation before starting.

  1. Action Open Settings if needed.
  2. Action Check the settings, then Export.
MP4 export confirmation: check the format and settings before proceeding. The product screenshot is in Japanese; the instructions explain the controls.
Export settings
Reviews whole-video settings such as fades, separately from clip settings.
Export
Starts final-video processing. Wait for saving to finish before treating it as complete.
PART04

Play and download the finished file

Open Output → Exported videos. Verify the language and timestamp, play the result and download it.

  1. Check Play and review the video and audio.
  2. Action Click Download.
Exported videos in the Output menu, with playback and download controls. The product screenshot is in Japanese; the instructions explain the controls.
Play
Checks picture, audio, captions, opening and ending.
Download
Downloads the video file. Saving the project alone does not produce an MP4.

BEFORE YOU FINISH

One final check.

After editing, check the intended presenter, clip and display language. Generate and play changes that require rendering, then check the saved status.
