How to change the voice and music in a reel you already made
Give Vizard Agent the reel and say what the voice and music should become. Vizard Agent generates the new narration in the register you name, sources matching music, rebuilds the scenes with the graphics measured into place, and adds scrims behind the text where it was fighting the picture.
What do you type into Vizard Agent?
Describe the voice as a person would. Vizard Agent searches by that description rather than by settings, so "a deep Hindi voice" gets a much better shortlist than any parameter, and naming the music style in the same sentence keeps the two matched. Send the original photos and clips if you have them, since rebuilding means re-cutting, not stretching.
Prompt
What does Vizard Agent actually do?
Changing the voice on a finished reel isn't a swap, it's a rebuild. The new narration has a different length and different pauses, so every scene has to be re-timed to it, which is also the moment to fix the things that weren't quite right the first time. In the session behind this article it:
- Downloaded the reel and the source photos, built a contact sheet, and checked the photos' orientation metadata, since a photo that displays upright in a phone gallery can be stored rotated.
- Searched for a deep voice in the target language, generated worship-style music, and generated the new narration and title graphics, measuring the voice track's level.
- Inspected each graphic frame by frame at full resolution, prepared vertical versions of every photo and re-rendered each scene with gentle motion at the new narration's length.
- Rendered the full reel with captions, measured the music slice and re-rendered after finding the music sitting too high against the narration.
- Measured where each graphic sat in frame, reframed the landscape photos and built soft scrims behind the text, then produced a second version with captions in another language.
- Delivered a vertical 1080x1920 reel of 61.0 seconds at 30fps.
When does this not work well?
Rebuilding around a new voice means the timing changes everywhere, and anything locked to the old read has to move with it. Working from the rendered reel alone rules out reframing, landscape photos in a vertical reel lose something, and burnt-in text from the old version stays unless the source files come with it. Religious and cultural wording deserves review by someone who knows the context.
Common questions
Can it just replace the audio? Not cleanly. A new voice has a different length and different pauses, so the scenes have to be rebuilt around it.
Do I need the original photos? Not strictly, and Vizard Agent does much better with them. Reframing and re-timing both need the source files.
Can I get two language versions? Yes. Vizard Agent shares the scenes and timing between them, so the second is cheap.
