How to cut an ad for your song without chopping the song up
Send Vizard Agent your master track and say the song must play as one take. Instead of splicing favourite lines together, it measures the beat and the lyrics, picks one unbroken window that starts on a downbeat and reaches the hook early, and cuts the picture to that window, keeping performance shots lip-synced.
What do you type into Vizard Agent?
Upload the master file, not just a video with the song in it, and say which lines must be in and which must not. A short ad can't hold every favourite line without splicing, and in a vocal track every splice is heard, so the choice of window is the real decision.
The song got chopped with the video and doesn't flow. Here's the MP3. Also, don't use the line about targeted ads, since this is going to run as an ad.
What does Vizard Agent actually do?
It treats the song as fixed and the picture as flexible. A 25-second window has to start on a downbeat, reach the hook quickly and avoid the lines you don't want, all without a single cut in the audio. In the session behind this article it:
- Had built the first version from four pieces of the track joined on bar lines, which the user heard as chopped.
- Lined up the artist's MP3 with the audio of the official video by cross-correlation, about 20 milliseconds apart, so the word timings and the 112 BPM beat grid measured on the video carried over to the master.
- Chose one 25-second window starting on a downbeat at 40.77 seconds, putting the hook at 0:12 and leaving the unwanted line outside it, and told the user a line they liked couldn't be reached without a splice.
- Trimmed 1 dB because the window peaked above zero, faded the last 1.1 seconds, and re-cut the picture on exact frame counts, catching a segment that came out at 612 frames instead of 600.
- Kept every performance shot at one fixed offset from the song so the singer stayed lip-synced, and kept the audio as one take when the user asked for the old opening look back.
When does this not work well?
When the lines you need are far apart in the song. If the hook and the line you want to open with sit a minute apart, no window of ad length holds both, and you have to choose between them or accept one splice placed carefully on a beat.
Common questions
Can it use my favourite lines? Only those inside one window. Vizard Agent says what is out of reach.
Will the singer stay in sync? Yes. Vizard Agent keeps performance shots at one offset from the song.
Why upload the MP3? Vizard Agent aligns it to your video so the timings carry over.
