How to Make an AI Rap Video
How to make an AI rap video in five steps: lyrics, track, character, generate, caption. One worked example and the three things viral ones share.
To make an AI rap video, start with a track. Upload your own audio, or describe a beat and let AI write the song. Then open an AI rap video generator, pick one character and a visual style, and generate. AITuber builds the visuals, times the lyric captions to each word, and exports a vertical video.
Key takeaways
| Question | Short answer |
|---|---|
| How do I make an AI rap video? | Get a track, pick a character and a style, generate, then caption the post |
| Do I need my own song? | No. AI can write the track from a description or from your lyrics |
| What files can I upload? | MP3, WAV, M4A, AAC, or OGG, up to 50MB and 10 minutes |
| What will not work? | An MP4 or a YouTube link. AITuber needs the audio file |
| How long should the clip be? | 30 to 60 seconds for Shorts, Reels, and TikTok |
| Do I have to label it as AI? | On YouTube, yes, when AI made the music and the music is the point |
What you are making
A music video made with AITuber
From the public AITuber catalog. This one is a pop song, and a rap video is built the same way: a song, AI visuals, and lyric captions timed to each word.
A rap video has three layers. The track sits at the bottom. The pictures change as the track moves. The lyrics appear on screen, one word at a time, as the voice says them.
The third layer matters most for rap. A fast verse is hard to catch by ear on a phone speaker. Words on screen let a viewer follow every bar.
Pick your starting point
There are two ways in. Which one you take depends on whether the song exists yet.
| You have | Do this | What AITuber does |
|---|---|---|
| A finished rap track | Upload the audio file | Reads the audio, finds the words, builds the video |
| Lyrics but no beat | Use custom mode and paste the lyrics | Makes a track that raps your exact words |
| Only an idea | Describe the beat and the topic | Writes the lyrics and makes the track |
You have a track
Upload it. AITuber takes MP3, WAV, M4A, AAC, and OGG files, up to 50MB and 10 minutes long. You can trim to the part you want.
Two things will not work. You can’t paste a YouTube or Spotify link, and you can’t upload an MP4. If your rap only exists as a video, export the audio from it first. If you already filmed a video and only want lyrics burned on, use a caption editor. That is a different job from this one.
The same upload flow sits behind our general AI music video generator, which covers every genre.
You want AI to write one
AITuber has a song maker built in. It works in two modes, and both are listed in AITuber’s public API reference.
Simple mode takes a description. You say what the song should sound like and what it is about. The AI writes the lyrics and makes the track.
Custom mode gives you the pen. You set the style, the title, and the exact lyrics, up to 5,000 characters. We’d use custom mode for rap every time. The bars are the whole point, and yours will sound less generic than a model’s.
Each run returns two versions of the song. Pick the one where the voice lands the hook harder. You can test the whole path with free credits on the free AI music video generator.
Worked example: “Night Shift”
We’ll build one video from nothing. The idea: a short rap about working nights in a warehouse. We wrote the lines below for this guide and did not run them through the tool, so treat them as a pattern.
1. Write the hook, then the verse
Write the hook first. It is the two lines people will repeat, and it should work with no setup.
Night shift, lights dim, everybody gone
Me and this beat keep the warehouse onThen write eight to sixteen bars that earn it. Keep each bar to one breath.
Clocked in at ten with the moon on my back
Forklift humming like the bass in the track
Boss wants more but the night wants sleep
So I stack these boxes and I stack this beatPut the hook at the top of the lyrics, before the verse. A viewer decides in the first line whether to stay.
2. Make the track
Open custom mode and paste the lyrics. Then write the style in plain music terms. Name the sub-genre, the tempo, the drums, and the voice.
Boom-bap, 90 BPM, dusty drums, warm upright bass,
calm low male voice, clear delivery, late-night moodLeave real artists out of the style line. “Sounds like” a named rapper is a request to copy someone’s voice. Describe the sound you want and you’ll get something you can own.
Listen to both versions. Check one thing above all: can you make out every word of the hook? If not, run it again with “clear delivery” and a slower tempo.
3. Pick one character and one style
Now the pictures. Choose one character and keep it in every scene. For “Night Shift” we’d use a raccoon in a yellow raincoat who drives a forklift. It is odd enough to remember and simple enough to draw the same way twice.
Write that into the visual direction box:
A raccoon in a yellow raincoat working the night shift in a huge
warehouse, sodium lights, wet concrete, moody and cinematicAI image models drift. A character can change face or outfit between scenes. The API reference describes one fix: save the character as an element, then mention it by its @handle in the visual direction. The model then gets the same reference picture for every scene.
For more characters and settings to borrow, see our AI rap video prompts. Want two rappers trading bars? See our guide to AI rap duo videos.
Pick a single art style to go with it. Cinematic gives a gritty film look. Anime gives a clean, bold look that reads well on a small screen. We’d take anime for a cartoon animal and cinematic for a human.
4. Generate
Three settings matter here.
- Visual mode. AI images shows a new picture every few seconds with slow camera moves. AI video makes short moving clips and costs more. Start with AI images.
- Shape. Choose 9:16 for Shorts, Reels, and TikTok.
- Captions. Leave them on. AITuber reads the words from the audio and times each one.
Trim before you generate. A 30-second cut of the hook and the best eight bars is cheaper to make, and it is what feeds want.
5. Caption the post
The video already carries the lyrics. The post caption has a different job. Put the hook line first, since that is the text people see under the video. Add the track title and where the full song lives. Two or three tags are plenty.
Three things viral rap videos share
We can’t hand you a formula, and nobody can. These three traits are the ones we’d build in every time.
A hook in the first line
The best line goes first. Most songs build up to the hook. A feed video can’t wait that long. If your track opens with eight bars of intro, trim the start so the video opens on the hook.
One character people recognise
A video with a new random face in every scene looks like a slideshow. One character gives the viewer someone to follow. It also gives you a series. The raccoon can clock in for a second track next week, and people who liked the first will know it on sight.
Simple beats detailed. One animal, one outfit, one colour. Viewers should be able to describe the character in five words.
Cuts that land on the beat
A picture change that hits the snare feels made on purpose. One that lands between beats feels random.
You can plan this with one sum. Divide 60 by the tempo, then multiply by 4. That gives the length of one bar in seconds.
| Tempo | One bar | Two bars |
|---|---|---|
| 80 BPM | 3 seconds | 6 seconds |
| 90 BPM | About 2.7 seconds | About 5.3 seconds |
| 120 BPM | 2 seconds | 4 seconds |
The API reference lists a seconds-per-image setting. The default is 4 and the lowest value is 3. So a 120 BPM track changes picture every two bars on the default setting. An 80 BPM track can change on every bar at 3 seconds. “Night Shift” at 90 BPM is the awkward one. We’d nudge the tempo to 80 or 120 before making the track.
Shorter gaps mean more images, and more images cost more credits.
Posting it
| Where | Shape | What we’d post |
|---|---|---|
| YouTube Shorts | 9:16 | 30 to 60 seconds, opening on the hook |
| Instagram Reels | 9:16 | The same cut |
| TikTok | 9:16 | The same cut, hook line in the caption |
| YouTube, full video | 16:9 | The whole track, with lyrics on |
Make the short cut first. If it gets watched to the end, make the full 16:9 version for your channel and link it from the Short.
Keep the on-screen lyrics on for every version. Many people watch with the sound off at first. The words give them a reason to turn it on.
Rights and AI labels
Three rules keep you safe.
- Use your own words. Lyrics you wrote are yours.
- Use your own voice, or an AI voice that is not a copy of a real person. Never clone a real artist’s voice. Never put a real artist’s face in the video.
- Leave real names out of your prompts. Describe a sound or a look.
A track you recorded follows normal music copyright. A track made with AI follows the terms of the tool that made it, so read those before you sell or stream it.
YouTube also asks for a label. Its help page says creators must disclose AI content when the music is the main focus of the video and AI made it. Realistic scenes that never happened count too. You tick “AI use” under Attributes when you upload. The same page says the label does not limit who sees the video or whether it can earn money. Our guide to YouTube’s AI labels covers the detail.
We could not load TikTok’s help page on the day we checked. Look for its AI label setting in the app before you post there.
What it costs
The price of one video depends on three things: the visual mode, the image quality, and the length of the song. Our rap tool page puts a typical AITuber rap video at about 80 to 100 credits. That includes making the track.
Signup gives 100 free credits with no card, which is enough to finish one. The AITuber Creator plan is $39 a month for 2,500 credits. At 80 to 100 credits each, that is about 25 to 31 rap videos a month. Live prices are on the pricing page.
Frequently Asked Questions
Basics
How do I make an AI rap video?
Get a track first. Upload your own audio, or let AI write the song from your lyrics. Then pick a character and a visual style, generate the video, and post a 30 to 60 second vertical cut.
Can AI write the rap for me?
Yes. Describe the beat and the topic, and AITuber writes the lyrics and makes the track. You get two versions. We’d still write the bars ourselves and paste them in.
Can I use my own lyrics?
Yes. Custom mode takes your exact lyrics, up to 5,000 characters, plus a style line and a title. The AI raps the words you wrote.
Files and settings
What audio files can I upload?
MP3, WAV, M4A, AAC, and OGG, up to 50MB and 10 minutes. You can trim the track before you generate.
Can I paste a YouTube link or upload an MP4?
No. AITuber takes audio files only. Export the audio from your video first, then upload that file.
How do I keep the same character in every scene?
Describe one simple character in the visual direction and repeat the same words each time. AITuber’s API reference also describes saved elements, which give the image model the same reference picture for every scene.
How do I make the cuts match the beat?
Work out the bar length. Divide 60 by the tempo and multiply by 4. Pick a tempo where one or two bars come to a whole number of seconds, such as 80 or 120 BPM.
Posting and rights
How long should an AI rap video be?
For Shorts, Reels, and TikTok, we’d post 30 to 60 seconds and open on the hook. Put the full track on YouTube in 16:9.
Do I have to label an AI rap video on YouTube?
Yes, if AI made the music and the music is the main focus. Tick “AI use” in YouTube Studio when you upload. YouTube says the label does not limit reach or earnings.
Can I make an AI rap in a famous rapper’s voice?
Don’t. Cloning a real artist’s voice or face without consent can get the video removed, and it can bring a legal claim. Describe a style and build your own character.
How we researched this: the upload formats, the two song modes, the lyric limit, the visual modes, the saved-element note, and the seconds-per-image setting come from AITuber’s own tool pages and its public API reference, read on 12 October 2026. We wrote the “Night Shift” lyrics, style line, and visual direction for this guide and did not run them through the tool. The showcase clip comes from AITuber’s public catalog and is a music video, not a rap video. The three traits in “Three things viral rap videos share” are our own view, not measured data. The Deezer figures come from TechCrunch’s July 2026 report. The YouTube rule comes from YouTube Help, “Disclosing use of GenAI content”. We read both that same day. We could not load TikTok’s help page, so this guide makes no claim about TikTok’s rule. AITuber prices and credits come from our live plan list. AITuber is our product.
The AI rap video generator page opens the song form with a rap prompt already filled in.
