How to Fandub an Anime: Step-by-Step Guide with a Rythmo Band

A fandub is a dub made by fans: you take a scene from an anime, a cartoon or a video game and record your own voice version of it. It is a great way to learn dubbing, alone or in a group, and animation is especially well suited to it. Here is a complete method for how to fandub an anime, from the clip to the final take, using a rythmo band (a scrolling dubbing script synced to the characters' lips) to stay in sync.

In short

• Scene length: 30 seconds to 2 minutes to start.
• Equipment: headphones, a microphone (a phone mic is enough to begin) and a quiet room.
• Method: pick the clip, adapt the script, assign the roles, generate the rythmo band, record, mix.

Why anime is a good fit for dubbing

In animation, mouth movements are often simplified: the mouth opens and closes without articulating every sound the way a filmed actor does. What matters most is respecting when the mouth moves and how long each line lasts, far more than the exact shape of the lips. That is exactly what a rythmo band shows: when to start, how long to speak and where to stay silent.

Anime voices do demand energy, though: shouts, breaths, laughs, short reactions. These are often what separates a so-so fandub from a convincing one.

1. Pick the clip (and check the rights)

An anime, like any film or series, is protected by copyright. Publishing a scene from a protected work with your voice on it means reproducing and adapting it: without permission that is not a safe use, even if some rights holders tolerate fan creations. The safest options:

• an animation you made yourself or with friends;
• an animated short published under a license that allows adaptation (check the exact terms);
• a protected scene kept for private use or a classroom workshop, with no publication.

For your first try, choose a scene with two or three characters, clear lines and little music over the voices: transcription and timing will be easier.

2. Adapt the script

If you are starting from a Japanese or other foreign-language version, do not translate word for word. Adapting means writing a natural line in your language that fits in the same amount of time as the original:

• read the original line out loud with the video, then yours: if yours runs long, shorten it;
• keep the strong words (a name, a shout, an attack) at the same moment as in the original;
• respect the silences: if the character stops talking, so does your text.

Studio vocabulary (labials, detection, loop) is explained in the dubbing glossary.

3. Assign the roles

One role per person is ideal. Solo, you can play every role by changing your voice, but record one character at a time. Give everyone the script before the session, with one intention per line (anger, surprise, mockery): that is what makes a fandub come alive.

4. Prepare the rythmo band

Upload the scene to the rythmo band editor. The dialogue is transcribed automatically, with the timing of each word and one role per character. Then replace the original text with your adaptation, line by line, and adjust the start and end of each line on the band. Every step is detailed in the guide to creating a rythmo band.

If the scene is in Japanese and you are writing your own script, the transcription is mostly there to place the lines in time: what matters is the timing, not the original text.

Finally, generate the video with the band burned in, in 16:9 for YouTube or 9:16 for TikTok and Reels.

5. Record

• Headphones are a must: without them, the video's sound leaks back into your mic.
• Do a test take first: listen to it and fix one thing (an earlier entrance, a less rushed ending).
• Shouts and breaths: record them boldly, at the right distance from the mic (step back a little for shouts so they do not clip).
• With a group: everyone can record from home using the collaborative mode, by joining the session through a link.

6. Mix and publish

The trickiest part of a fandub is the original soundtrack: the Japanese voices are blended with the music and effects. In studios, dubbing is done over an international version that contains only music and effects; as a fandubber, you almost never have access to one. So you lower the original track, or replace it with royalty-free music and a few sound effects.

Before publishing, reread the rights section above, credit the original work if you have permission to use it, and get the agreement of every participant.

Frequently asked questions

Do I need to speak Japanese? No. A translation or subtitles are enough to understand the scene; your job is to write a version in your own language that fits in the time.

How long does a scene take? Plan on an hour for a one-minute scene: adaptation, rythmo band, two or three takes per person and a simple mix.

How do you dub a cartoon? Pick a short clip you have the rights to, adapt the lines so they fit in the same time, generate a rythmo band, adjust the timings, then record your own voice following the band. Character voices and vocal sound effects call for bolder acting than live action.

Is dubbing a cartoon easier than dubbing a film? Often, for sync: drawn mouth movements are simpler and more forgiving. You still need real vocal acting, more expressive and more distinctive.

Can you fandub alone? Yes, by voicing several characters or by picking a scene with a single character. For a group session, read our guide to the dubbing night.
