How to score a trailer with only the music already in your video
Tell Vizard Agent to drop the added music and use only what is in your video. It checks whether a bed runs under your narration, finds music-only stretches between your lines, and fills the trailer's pauses and ending with pieces of your own music, levelling each narration line so nothing jumps.
What do you type into Vizard Agent?
Say that the new music clashes and what to do instead. A trailer cut from a video that already has its own score inherits that score under every line, so any added music doubles up. The fix is to treat the original as the only music, not to find a better added track.
Take away all the music you've added. It clashes with the existing music.
What does Vizard Agent actually do?
It first proves the original music is everywhere, then mines it for the pieces it needs. A trailer still wants music in its pauses and under its end card, and the cleanest source is the creator's own playing. In the session behind this article it:
- Measured the loudness under thirteen narration lines and found none silent, confirming a bed runs under every line.
- Listed gaps of more than three seconds in the transcript, joined the candidate music-only stretches into one file and had it listened to.
- Found two of the six still contained speech, re-derived the gaps, and auditioned a second set: an opening, a slow guitar passage and the outro riff.
- Rebuilt the soundtrack from the source alone, levelling each narration region to a common loudness with short fades and filling the three pauses with the slow passage.
- Put the outro riff under the end cards and had the mix checked for clipped words, clicks and jumps in background noise at the joins.
When does this not work well?
When the original has no music-only moments. If the narration never stops, every piece of the bed has speech on it, and the pauses in the trailer have to stay quiet or use a new cue after all. Music that changes key between sections can also make the joins audible.

Where does the music for the pauses come from? Vizard Agent finds stretches of your own music with no speech.
Will the narration levels jump? No. Vizard Agent levels each line before joining them.
