Why Japanese creators caption with Clipzi

Line breaks where they belong

Japanese runs words together with no spaces, so a bad break splits a word and reads wrong. Clipzi breaks captions at natural phrase boundaries so each line scans the way you would actually read it aloud.

Kanji, hiragana and katakana mixed

Real Japanese mixes all three scripts in one sentence. The transcript keeps them as written, so 東京タワーに行った comes out with the kanji, katakana and kana intact, not romaji.

Made for the creator scene

Anime reaction channels, VTuber clips, gaming and street-interview content all live or die on captions in Japan. Burned-in subtitles travel well to clip accounts and overseas fans.

How it works

Reframe to 9:16

Crop to vertical, pick a caption style, and fix any reading the model got wrong.

Download with Japanese captions burned in and upload to Shorts, Reels or TikTok.

Features

Whisper transcription

Solid on clear Japanese speech across kanji, hiragana and katakana. Studio audio gets you most of the way before edits.

Karaoke captions

Text highlights as spoken, which suits fast talk and reaction content where timing matters.

Phrase-aware line breaks

Lines break at phrase boundaries and stay short, because Japanese captions read worse when they wrap mid-word.

Speaker detection

Collabs and multi-VTuber streams get separated by voice so viewers can follow who said what.

Vertical reframe

Reframe a horizontal stream into a clean 9:16 clip for Shorts and TikTok.

Full editing on free

Two videos a month, all editing tools, small watermark only. No watermark from $9/month.

Frequently asked questions

How accurate is Japanese transcription?+
On clear speech it is good, and it returns proper kanji and kana rather than romaji. Where it slips is homophones (same sound, different kanji) and uncommon proper nouns, character names or slang, so check those. The editor lets you swap the kanji fast.
Does it handle kanji, hiragana and katakana together?+
Yes. A normal Japanese sentence mixes all three plus the odd Latin word, and the transcript keeps them as written instead of flattening everything to romaji.
How does it handle line breaks with no spaces?+
Because Japanese has no spaces between words, Clipzi breaks lines at phrase boundaries and keeps each line short. That stops a word from being split across two lines, which is the main thing that makes Japanese captions hard to read.
Which formats can I upload?+
MP4, MOV and WEBM, up to 3GB on the free plan.
Is there a watermark?+
The free plan has a small watermark and two videos a month with full editing. Paid plans start at $9/month with no watermark.
