Step 3: Save It to the Scene

Drag your chosen avatar onto the canvas and lock the position.

Repeat for the rest of your scenes to keep one presenter throughout.

✅ 結果: Your video now has a consistent AI presenter across every scene.

💡 プロのヒント: A custom personal avatar costs $1,000 per year. Test the stock avatars first before you commit.

Switch on closed captions so viewers can follow without sound.

Step 1: Arrange Your Scenes

Each scene is a card, much like a slide in PowerPoint.

Synthesiaでよくある間違いを避ける方法

Mistake #1: Writing the script last

❌ 間違い: Picking avatars and templates first, then forcing text to fit the scenes you already built.

✅ 右: Write and cut the script first. It decides most of whether the video works.

Mistake #2: Cramming every scene

❌ 間違い: Stacking text, charts and animations on one slide until viewers stop following.

✅ 右: One idea per scene. Let the AI voice carry detail the screen doesn’t need.

Mistake #3: Skipping the preview

❌ 間違い: Clicking generate on a 12-minute video without checking pacing or pronunciation.

✅ 右: Preview every scene, then generate. Waiting for a re-render costs more than a two-minute check.

Synthesiaのトラブルシューティング

Problem: Video generation is stuck

原因： Long videos queue behind other jobs during busy hours.

修理： Generation normally takes 3 to 20 minutes depending on length. Close the tab and wait for the email. Split anything over 10 minutes into shorter videos.

Problem: The avatar mispronounces your brand name

原因： The speech engine guesses unfamiliar words from spelling alone.

修理： Add the word to your pronunciation glossary with a phonetic spelling. Regenerate that scene only, not the whole video.

Problem: An uploaded clip won’t play

原因： The file uses an unsupported codec or exceeds the upload limit.

修理： Re-export as an MP4 with H.264 video and AAC sound, then upload again. Keep single files under the plan limit shown on the upload page.

📌 注記： If none of these fix your issue, contact Synthesia support.

Synthesiaとは何ですか?

シンセシア is an AI video generator that creates studio-quality videos from text.

Think of it as a film crew that lives in a browser tab.

You write, it casts an avatar, records the voice and edits the result.

Companies create videos this way for onboarding, product updates and customer service.

Every video created here can be updated later without re-recording anything.
