How to make a lyric video with beat-synced screen shaking
Upload your track to Vizard Agent and say you want the screen to shake harder on the heavy parts. It transcribes the vocals with word timings, measures the song's energy and harshness across its whole length, and ties the shake to those measurements, so the effect intensifies where the track actually gets heavier.
What do you type into Vizard Agent?
Describe the rule, not the timestamps. Vizard Agent measures the song and works out where the rule applies, so "more shaking when it gets heavy" is a complete instruction. Name one effect rather than asking for "effects", and say how far to push it, because that's the note people give most often on the first cut.
Prompt
What does Vizard Agent actually do?
It builds an intensity curve for the song and drives everything from that. Where a song gets heavy isn't a section boundary you can guess from its structure. It's a measurable property of the audio, and once it's measured the shake can follow it continuously instead of switching on and off at a marker. In the session behind this article it:
- Probed the uploaded file, checked the audio track, grabbed a full-resolution frame of the artwork and loaded its music-video playbook rather than improvising a structure.
- Transcribed the vocals with word timings, analysed the song structure to locate the growl sections and read the full transcript.
- Measured the song's energy and harshness envelopes across its whole length.
- Browsed the available fonts, read every word-level timing and cropped the artwork for the background and the logo.
- Indexed every sung word and built the lyric line files against the measured curves.
- Delivered the full song at 1920x1080, 24fps and 267.01 seconds, with the lyrics timed to the words and the shake tracking the song's own intensity.
When does this not work well?
Heavy music is exactly where the audio gets harder to transcribe. Growled and screamed vocals transcribe badly, so you'll likely need to paste the lyrics for those sections. The first cut is almost always too much, so ask for less shake than you think you want. The lyrics must stay legible, and heavy shake is a real accessibility problem for some viewers.
Common questions
Can it transcribe screamed vocals? Poorly. Paste the lyrics for those sections and Vizard Agent times them against the audio.
What if the shake is too strong? Say so. Vizard Agent lowers the amplitude against the same curve rather than rebuilding.
Can the font change with the music? Yes. Vizard Agent can tie bigger type on the heavy parts to the same measurement.
