How to make a guess-the-lyric quiz video

Last updated 2026-08-22 · 6 min read

Give Vizard Agent the song list and the quiz format. Vizard Agent sources the audio, transcribes every track to find where each verse begins, verifies the timings by cutting samples and re-transcribing them, and builds matching question and answer cards for the whole round.

What is the short version?

A guess-the-lyric quiz is a timing problem wearing a graphics costume. The clip has to cut at the exact moment the line the player must complete stops, and finding that moment in fourteen songs is the entire job.

Go to Vizard Agent and list the songs.
Say the format — how much plays, where it stops, how the answer appears.
Say the look and the length.

What do you need before you start?

The song list and the rules of your round. Vizard Agent sources the audio and works out the verse boundaries itself, and the details worth stating are how much of each song plays and how the answer is revealed, because those two decide the whole rhythm.

The song list. Fourteen makes a full round.
The format. Play a line, cut, then instrument-only with the lyric on screen.
The look. A background theme and a card style.
The pacing. How long players get to answer.
Sound effects. A tick, a ding, a whoosh. They do a lot of work.

What do you type into Vizard Agent?

Describe the round as you would explain it to a player. Vizard Agent turns that description into per-song timing rules, so telling it what the viewer sees and hears in each round is more useful than any technical instruction about cut points.

Prompt

Make a guess-the-lyric quiz video for these [14] songs. For each one, play the first lines, cut, then play the instrumental with the lyric text on screen as the answer.

Variants worth knowing:

A visible countdown. It changes the format from a video into a game.
A themed background. Vizard Agent generates one to match the subject.
A shorter round. Five songs makes a social-length version.

What does Vizard Agent actually do?

Here is the order Vizard Agent worked in on a real quiz video. The middle of it is verification: Vizard Agent did not trust the first transcription of where a verse started, it cut a sample and listened again.

Sources the audio for every song on the list and checks the durations and formats.
Transcribes all fourteen tracks to get the lyrics with timestamps.
Tests vocal-reduction filters for the instrumental portion of each round.
Analyses each song's energy profile and transitions to find the structure.
Analyses the audio pattern to detect where each verse actually starts.
Cuts sample clips at the candidate start times and re-transcribes them to verify the vocals begin where it thinks.
Detects the beat onsets and harmonic energy spikes for each track.
Generates the quiz sound effects — tick, ding, whoosh — and a themed background image.
Builds the question and answer cards, checks them on frame, renders all fourteen rounds and joins them, then verifies the audio-visual sync on the finished video.

Step 6 is the habit that makes the quiz playable. A verse start that is half a second out makes the cut feel wrong to every player, and the only way to be sure is to cut it and listen.

What does the result look like?

From the run this page is written from, probed on the delivered file: 1920x1080, H.264, 30fps, 328.87 seconds, AAC audio. Widescreen, five and a half minutes, fourteen rounds each with a question card, a cut at the right moment and an answer card over the instrumental.

Five and a half minutes for fourteen questions is around twenty-three seconds a round. That is enough to hear the line, feel the pause and see the answer, which is the pacing a quiz lives or dies on.

When does this not work well?

Music is the raw material for this format, and music has owners. Vizard Agent sources what it can find and builds the rounds around it, and the rights question sits with you rather than with the edit itself.

Music licensing is yours. Where you publish decides what you may use.
Transcription of singing is imperfect. Vizard Agent verifies the timings and the lyric text may still need your eye.
Instrumental versions are not always available. Vocal reduction is a fallback, not a clean stem.
Obscure tracks may not be sourceable. Supply the audio yourself if the song is rare.
Fourteen rounds is long for social. Ask for a five-song version for a feed.

How do you fix a result that came back wrong?

Name the round. Vizard Agent keeps every transcription, the verified start times, the energy analysis and the rendered cards, so moving a cut or correcting a lyric is a re-render of one round rather than the whole quiz.

"Round seven cuts too early." Re-timed against the verified verse start.
"That lyric is wrong." Corrected on the answer card.
"Give players longer." The pause is extended across every round.

How does Vizard Agent compare to doing it yourself?

By hand this is a long evening. By hand this is finding fourteen separate tracks, scrubbing each one of them for the exact moment a line ends, building twenty-eight cards to match, and then discovering that half your cuts land a beat late.

	By hand	Vizard Agent
Finding the verse starts	Scrub by ear	Transcribed, then verified by re-cutting
Instrumental sections	Hunt for versions	Sourced, or vocals reduced
Twenty-eight cards	Build each one	Rendered from one design
Checking the sync	Watch it through	Verified on the finished file

Common questions

Does this work for other quiz formats? Yes. The method is the same for a guess-the-film-score round, a name-the-intro round or a finish-the-quote round: find the exact moment to cut, verify it, and build matching cards on both sides of the pause.

How many songs make a good round? Ten to fifteen. Fourteen was a full round on this one.

Does it find the lyrics itself? Yes. Vizard Agent transcribes each track and verifies the timings by re-cutting samples.

Can it make the instrumental section? It sources instrumental versions where they exist and reduces the vocals where they do not.

Can I supply my own audio? Yes, and for rare or regional tracks it is the reliable route. Vizard Agent will transcribe and analyse what you give it exactly as it would a sourced file.

Does it add sound effects? Yes — a tick under the pause, a ding on the reveal.

Can I get a short version for social? Yes. Ask for five rounds and Vizard Agent builds it from the same analysis.

Does it design the cards? Yes. Vizard Agent renders the question and answer cards and checks them on frame before building all fourteen rounds.

Can it make a themed background? Yes. Vizard Agent generates one to match the subject of the quiz.

How does it verify the cut points? It cuts a sample clip at each candidate start time and re-transcribes it, so the vocals are proven to begin where the round needs them to.

Does it check the finished file? Yes. Vizard Agent verifies the audio and visual sync on the delivered video.
