HeyGenのプロ向けヒントとショートカット
After eight months of daily use, here are my most useful tips.
Here is how the tool performed in my own testing:
Analyze performance for each language before you scale ad spend.
Then focus your budget on the markets that actually convert.
A few habits made the biggest difference to output quality:
キーボードショートカット
| アクション | ショートカット |
|---|---|
| プレビューを再生または一時停止 | 空間 |
| 最後の編集を元に戻す | Ctrl + Z |
| Duplicate selected scene | Ctrl + D |
| プロジェクトを保存 | Ctrl + S |
ほとんどの人が見逃す隠れた機能
- Pronunciation editor: Fix brand names the voice mangles by spelling them out phonetically.
- Pacing controls: Slow the avatar down on your key message so it actually lands.
- ブランドキット: Lock your fonts and colours once and every new video inherits them.
HeyGenでよくある間違いを避ける方法
Mistake #1: Publishing translated videos without a human check
❌ 間違い: Trusting ai video translation to be publish-ready on its own.
✅ 右: Ask native speakers to check the translations. Accuracy on wording still needs a human pass.
Mistake #2: Writing scripts like blog posts
❌ 間違い: Long, clause-heavy sentences that the avatar rushes through.
✅ 右: Short sentences under fifteen words, written the way you actually talk.
Mistake #3: Cloning your voice from a bad sample
❌ 間違い: Recording your voice sample on a laptop mic in a noisy room.
✅ 右: Use a quiet room and a decent microphone. The clone copies whatever it hears.
HeyGenのトラブルシューティング
Problem: Video translation is stuck processing
原因： Free accounts share a slower render queue than paid ones.
修理： Leave the tab open and wait. Upgrade if you translate videos regularly.
Problem: The translated audio drops whole sentences
原因： The tool trims words so the new audio still fits the original video length.
修理： Shorten your source script, then re-run the translation on the trimmed cut.
The technology is still in beta, so translating long videos can produce awkward phrasing.
Problem: Lip movements look out of sync
原因： Source footage was low resolution or the face was partly turned away.
修理： Re-upload a front-facing clip at 1080p or higher and process it again.
