How to film a music video with your phone
Your phone is enough for the picture. What makes a music video look professional comes down to three things: the song playing during every take, four cameras filming the same passage, and cuts placed in the right spot. Here's how to do it, step by step.

Prepare the song
Everything starts with the final version of your song, as a file on your phone: MP3, WAV, AAC or M4A. No file yet? Here's how to put music on your phone.
In TREMOLO CUT, everything starts with “New project”. The app first asks how you want to edit: Automatic, the app edits for you; or Studio, you control every setting. You can switch between them at any time.
Then pick your song in “My songs”, or with “Import a file”, and tap “Analyze the music”. The app separates the drums from the melody, finds the peaks, build-ups and quiet moments, and computes your filming plan.
While you film, the app plays the song: that's the playback. You listen and sing or play along. Every camera is filmed over the same song, which is what lets the app sync them. The music is your timeline.
Filming with another phone or a camera? Play the song out loud next to it during every take, loud enough for the device to record it. On import, the app finds where your video fits in the song. Best imports: steady shots of 20 s or more.
Tip Really sing, don't just mime: lips follow the sound, and it shows on screen.
Choose your section and editing style
Once the music is analyzed, choose your music video's length and format:
- The length: 15 s (Viral), 30 s (Quick), 1 min (Standard) or the full song.
- The format: portrait 9:16 for TikTok and Reels (recommended), landscape 16:9 for YouTube, square 1:1 for posts.
- Your favourite part: drag both handles to grab the exact part of the song you want to film, and play it before moving on. The chorus is often the best pick.
In Studio mode, you also set the cut rhythm, on the “Rhythm & editing” screen:
- Sync: On the beat, the cuts land on the drum hits; On the melody, they follow the notes of the melody, most of the time the vocal line; Hybrid, both at once.
- Intensity: from a calm edit with longer shots, up to a dynamic or even intense rhythm. The number of shots to film follows the slider.
In Automatic mode, the app makes these choices for you. All that's left is to tap “Start filming”.
Four cameras, four spots
In the app, a camera is one way of filming the same song: from the front, from the side, from far away. You stand in one spot and film the whole part. One camera = one spot.
Filmed with a single camera, a music video looks like a recording of a performance. With 2 cameras, the edit unlocks; with 4, you get ideal coverage, in studio quality. The app then switches between them to the rhythm of the music.
Medium
Frame the person from head to waist, like in a normal conversation.
Tight
Only the face, from forehead to chin. In the edit, close-ups land on the chorus for more impact.
Free
Move with the rhythm, or film a detail: hands, lips. It gives the music video depth.
Set up your phone
- The eyes must be sharp. Tap on the face to focus. On iPhone, a long press shows “AE/AF Lock”: focus and exposure stop moving.
- The best light is near a window. Facing the person, never behind them: backlight turns a face into a silhouette.
- Wipe the lens with your t-shirt. It changes everything.
- Turn on the grid in your camera settings: it helps you place the person in the frame.
- Turn on Do Not Disturb. One notification during a take and you're filming it again.
- Elbows against your body: that's your tripod. Or rest the phone on something stable; even a table or a wall can do. And move slowly, even if the music is fast: a gentle move makes the video look pro.
- Also filming with other devices? Keep the same settings everywhere: resolution, frame rate, orientation.
Film each camera
On each camera card: “Film”, with the music, or “Import” an existing video. You can do several takes: each camera shows the percentage of the part it covers. At 100%, it's complete.
Keep the same outfit, the same light and the same energy from one camera to the next: once edited, the takes should look like they were filmed at the same moment.
For the chorus, the guru's tip is simple: “film with energy — move the camera with the rhythm.”
Without a dedicated app, film each camera over the whole song, without stopping: when editing, you'll be able to pick any camera at any moment.

The craft
Cut in the right place
This is the step that separates an amateur music video from a pro one, and the one nobody explains.
- Cut on the beat. A camera change that lands off the beat is felt, even when you can't say why.
- But not on just any beat. A beat often lands in the middle of a sung phrase: the cut is right on the rhythm, and the voice is cut in half. Wait for the end of the phrase, or the breath.
- Follow the song's structure. Few cuts in the verse, more in the chorus. Change cameras when the song changes section: that's where the ear expects something new.
- Alternate distances. For an upbeat music video, alternate wide and tight shots on the strong beats. Two shots at the same distance back to back, and the cut looks like a mistake.
- Let it breathe. A video that cuts on every beat is tiring. The pace of the cuts follows the song's energy, not the metronome.
These rules come from twenty years of editing. The app's guru sums it up: “I cut on the music, never mid-phrase.”
Edit your music video
By hand, in editing software: you import your cameras, sync them one by one to the sound, then decide on every cut. It's doable, but it's slow, especially the syncing.
With TREMOLO CUT: as soon as 2 cameras are filmed, “Generate my clip” launches the edit locked to the music; with all 4, it's “Create my optimal clip”. Not convinced? Regenerate: every version is different. In Studio mode, you can also edit each shot.
Everything happens on your phone: no video is ever uploaded to a server, and your takes stay safe. Your first full project is free, exported in 1080p.
FAQ
How many cameras do you need for a music video?
Four: wide, medium, tight and free. Two are enough to unlock the edit; four give ideal coverage, in studio quality.
What audio file do you need to film a music video?
Your song as an MP3, WAV, AAC or M4A, saved on your phone. The app plays it while you film each camera.
iPhone or Android: which is better for filming a music video?
Both work. What matters is using the same settings for every camera.
Do you need to know how to edit?
No. In Automatic mode, the app edits for you. In Studio mode, you control every setting: cut rhythm, shot editing.
Are my videos uploaded to a server?
No: all the editing happens on the phone. No video and no music ever leaves the device.
Do I need an internet connection?
No. The app works offline: you film, edit and export even in airplane mode. All you need is the song on your phone.
