Line Distribution Video Maker: See Who Sings the Most in Any K-pop Song

Every comeback brings the same question in the comments: who got the most lines? A line distribution video answers it on screen. As the song plays, each member's bar grows while they sing, the ranking shifts in real time, and by the last chorus everyone can see exactly how the song was split.

This guide explains what a line distribution video is, how the seconds are counted, and how to make one from any song in Colorcoded, with AI doing most of the timing and singer work.

What is a line distribution?

A line distribution is how a song's singing time is divided between the members of a group. It's usually measured in seconds and shown as a percentage of the song, so you can compare who sings the most and who sings the least.

A line distribution video turns that into an animation:

One bar per member, in the member's color, often with their photo.
Each bar grows only while that member is singing.
The bars re-rank as the song goes on, so you can watch someone climb from last to first in a single verse.
The current lyric appears under the bars in the singer's color, so viewers can match the voice to the name.

Fans use them to compare members, track how distribution changes between eras, and settle "who was center this comeback?" debates with numbers instead of impressions.

How line distribution is counted

The numbers are only as good as the timing behind them. A fair line distribution follows a few rules:

Count seconds, not lines. A long held note matters more than a two-word ad-lib. Each member's total is the sum of the time they actually sing.
Split shared lines. When one lyric line passes from one member to another mid-line, each part should count for its own singer.
Count unison parts for everyone singing. If three members sing a line together, all three get the time.
Decide on ad-libs and background vocals. Most creators count audible ad-libs and skip faint background layers. Pick a rule and keep it for the whole song.
Use the official audio. Live versions and remixes can change who sings what.

In Colorcoded the totals come straight from your lyric timing: every line has a start and end time and one or more singers, and split lines keep a separate singer per part. The bars are exact to the tenth of a second.

How to make a line distribution video

You can make one in your browser or on the iPhone or Android app. The whole process takes minutes, not an evening in a video editor.

Create a project and pick Line Distribution as the video type.
Upload the song. Use the official audio, as an MP3 or WAV.
Add the lyrics. Paste them, or import a colorcodedlyrics.com link to bring in the lyrics, translations and member assignments in one step.
Add the members with their colors and photos. Their order is the number key you'll press to assign them.
Time the song with AI Timing. It times every line automatically. On the web, with Group by singer turned on, it also splits the song into parts where the voice changes, so you play each part and press the singer's number once instead of assigning every line by hand.
Check the handoffs. Play any line, split a part where two members share it, and add a second singer with Shift for unison lines.
Export. The bars, ranking and lyric caption are generated from your timing automatically.

Can AI do line distribution automatically?

Partly, and it's worth knowing where the limit is.

AI is very good at timing: matching each lyric line to the exact moment it's sung. That's the slowest part to do by hand, and Colorcoded's AI Timing does it for the whole song.

AI is also good at hearing that the voice changed. That's what Group by singer uses to cut the song into parts.

What AI can't reliably do yet is tell which member is singing. Idol voices in the same group are trained, processed and layered to blend, and even specialised voice-recognition models struggle to tell them apart. So Colorcoded leaves the final call to you: it gives you the parts, you play each one and press the right member. Fans who know the group can do that faster and more accurately than any model.

Line distribution vs color coded lyrics

The two formats answer different questions:

	Line distribution	Color coded lyrics
Main question	Who sings the most?	Who sings this line?
On screen	Ranked bars and seconds per member	Lyrics in each member's color
Lyrics	One caption line under the bars	Full lyrics, often with romanization and translation
Best for	Comparing members, comeback discussions	Learning and singing along with the song

Many channels post both for the same song. Since both come from the same timing, you only time the song once.

Mistakes to avoid

Timing from a fan-edited or sped-up audio. Distribution should match the official release.
Giving a whole line to one member when it's split. Short handoffs inside a line add up over a song.
Forgetting unison and harmony parts. Leaving them out makes the main vocalists' numbers look higher than they are.
Colors that are too close. Two similar blues make the bars hard to read at a glance; pick clearly different colors, ideally the group's official member colors.
Not checking the result. Watch the final video once: if a bar moves while you can hear someone else, a line needs a fix.

FAQ

What does line distribution mean in K-pop?

It means how the lines of a song are divided between the members of a group, usually measured in seconds sung and shown as a percentage. A line distribution video shows those totals as animated, ranked bars while the song plays.

Is there a line distribution generator?

Yes. Colorcoded generates the line distribution video from your lyric timing: you add the song, lyrics and members, AI Timing times the lines and groups them by singer, and the bars, seconds and ranking are calculated automatically.

Can AI make a line distribution automatically?

AI can time every line and detect where the singer changes, which does most of the work. Identifying which member is singing still needs a person, so Colorcoded lets you play each detected part and assign the member with one key press.

How are seconds counted when members share a line?

Split the line at the handoff and each part counts for its own singer. When several members sing together, the time counts for each of them.

Can I make a line distribution video for free?

You can build and preview a line distribution video for free. Exporting the final video needs Pro.

Make your first line distribution

Pick a song you know well, time it with AI, and check each handoff by ear. Once your timing is right, the bars take care of themselves, and you can export the same project as a color coded lyrics or karaoke video too.
