Japanese extras stay in VO

Why most anime fandubs fail — and how to avoid it

The two most common problems with fandub anime VFs: the sync is off because the dubber recorded off subtitles, and the secondary characters are either silent or replaced with synthetic audio.

Recording off subtitles creates a characteristic delay. The subtitle appears after the mouth has moved. You read, process, then speak. By the time your voice starts, the character is already mid-way through the line.

A rythmo band eliminates that delay. The line scrolls toward you before it starts. You see it coming and begin speaking at the right moment.

Leaving extras and side characters in the original Japanese is not a limitation — it is a feature. A scene where Luffy speaks French and the crew speaks Japanese sounds deliberate and professional. A scene where every character speaks French but the extras were generated by AI sounds fake.

Fandub with a crew or solo

Anime VFs often involve several people — one takes the protagonist, another takes the rival, a third takes the narrator. RythmoClip supports multiple accounts on the same scene. Each person logs in, records their assigned characters, and the export combines all takes into one file.

No shared project file. No one waiting for someone else to finish. Each person works on their own schedule from their own browser.

Solo dubbers can also take multiple characters — record one role at a time, then move to the next. The scene builds up take by take.

Frequently asked questions

Can I dub a full episode?

Yes, up to 2 GB. Trim to the scene you actually want to dub before you prepare — it keeps the transcription fast and the session manageable.

What happens to the Japanese characters I did not take?

They stay in the original Japanese audio in the exported file. Only the characters you marked to dub get your recorded voice.

Can we be several friends each voicing a character?

Yes. Each person logs in with their account and records their assigned character. The export combines all takes automatically.

Do I need to be in the same room as my co-dubbers?

No. Each person records from their own browser, anywhere. There is no real-time session — each take is recorded independently.

What format does the export use?

A single MP4 at the original video resolution. No watermark. Ready to post on YouTube or TikTok.
