How to clean up an avatar video you already made
Upload the avatar video and tell Vizard Agent it needs to look cleaner. Vizard Agent inspects the framing at full resolution, generates a proper studio portrait of the same presenter, re-syncs your existing audio to it, then adds captions and graphics checked on real frames.
What do you type into Vizard Agent?
One sentence is enough. Vizard Agent inspects the video and decides what's actually wrong, which is more reliable than a list of symptoms when the underlying problem is usually the source image. Saying what must stay is worth it, because the voice is often the part that was already right.
Prompt
What does Vizard Agent actually do?
A rough avatar video is usually rough because of the source portrait, not the animation. Repairing the frames you have is slow and rarely works. So Vizard Agent treats the original as a reference for what the presenter looks like and rebuilds the shot around the audio you're keeping. In the session behind this article it:
- Extracted frames and a transcript, and examined the original avatar at full resolution across several frames, including the crop around the presenter.
- Prepared the presenter as a reference image and generated a proper studio portrait from it.
- Sent the existing audio track for lip-sync against the new portrait and reviewed the high-definition talking avatar's frames as a grid.
- Generated styled animated captions from the transcript, then adjusted their position and colour after testing them on frame.
- Built a title badge, updated its typography after review, rendered with music and verified the lip-sync and legibility. The delivered file was vertical, 1080x1920 at 24fps and 15.04 seconds, with the same voice and script.
When does this not work well?
Rebuilding the presenter means generating a person again, and the new one is a close relative of the original, not the identical figure. A cleaner presenter won't match earlier episodes of a series exactly. The audio sets the ceiling, because Vizard Agent keeps your voice track, flaws included. And it's still a generated presenter, so don't present it as filmed.
Common questions
Do I need the original portrait file? No. Vizard Agent reads the presenter's appearance from the video's own frames.
Will it look like the same person? Close, and not identical. The portrait is regenerated from a reference rather than restored.
Does the length change? No. Vizard Agent keeps your audio untouched, so the video comes back at exactly the same duration.
