このガイドを信頼する理由
I have used Descript for two years across podcasts, client tutorials, and ユーチューブ uploads. Every step here comes from real projects, not a press kit.
Descript is a video editor and audio editor built around a transcript.
You edit audio and video by editing words, which is why beginners pick it up quickly.
It is a powerful tool for producing high quality content in one audio video workflow.
Most people stop at cutting 文章 and never touch the advanced features.
This guide walks through all nine, step by step, with screenshots and pro tips.
The goal is a faster editing process that still protects your creative vision.
説明チュートリアル
This How to Use Descript tutorial covers setup first, then every feature, from text based editing to AI Green Screen.
説明
Edit video by editing text. Descript transcribes your files, strips background noise with Studio Sound, and cuts filler words in one click. Start on the free plan, no card needed.
Descriptを使い始める
Setup takes about three minutes and only happens once.
Here is how Descript works in a real project:
それでは、各ステップを順を追って見ていきましょう。
ステップ1：アカウントを作成する
Go to the Descript website and click Sign Up.
Email, Google, or single sign-on all work for a new account.
✓ チェックポイント: チェックしてください 受信トレイ 確認メールをお送りします。
Step 2: Install the Desktop App
Descript works in Chrome, but the マック and Windows apps handle large video files better.
There is no mobile app, so plan to edit at a desk.
ワークスペースは以下のようになっています。
✓ チェックポイント: You see the script editor on the right and the scene rail below.
ステップ3：最初のプロジェクトを作成する
Click New Project, then upload an audio or video file to start.
Projects hold big productions, and compositions hold alternate cuts of the same recording.
✅ 完了: これで、以下のすべての機能をご利用いただけます。
How to Use Descript Text-Based Editor
テキストベースの編集 lets you cut audio and video files by deleting words in a transcript.
Text based editing is the reason most people switch to Descript. Delete a sentence in the script editor and the matching footage disappears from the timeline.
ステップ1：成績証明書を開く
Import a video file and wait for the transcript to load.
The script editor opens beside your timeline, and it reads like a word document.
Step 2: Delete the Bad Takes
Highlight the words you want gone and press delete.
これがその様子です。
✓ チェックポイント: Deleted words show as a strikethrough line, and the video skips them.
Step 3: Play It Back
Press space to review the cut before you export anything.
✅ 結果: Your first text based editing pass is done in minutes, not hours.
💡 プロのヒント: Enable Ignore Deleted Text to hide old lines and keep the script clean while editing.
Descript AI音声クローニングの使い方
人工知能 音声クローン lets you fix a flubbed line by typing it in your own voice.
AI voice cloning trains on a short recording of your own voice. Descript then speaks new words for you when a re-record is not practical.
Step 1: Train Your Voice
Record the consent script Descript gives you, roughly ten minutes of clean audio.
Step 2: Type the Fix
Click into the transcript and type the corrected words.
これがその様子です。
✓ チェックポイント: The new words appear in the waveform with a small AI badge.
Step 3: Blend the Audio
Adjust pacing so the generated audio matches the original audio around it.
✅ 結果: One typed line replaces a full re-record session.
💡 プロのヒント: Train voice cloning in the same room and mic you always use, or the patch will stand out.
Descript Studio Sound の使い方
スタジオサウンド lets you remove background noise and echo from any audio file.
Studio Sound is the fastest way to make a laptop mic sound close to a booth. It strips room echo, hiss, and background noise in one pass.
Step 1: Select the Track
Click the audio layer you want to clean up.
Step 2: Toggle Studio Sound
Turn it on in the right hand panel and set the strength slider.
これがその様子です。
✓ チェックポイント: Room echo drops away and the voice sits forward in the mix.
Step 3: Compare Both Versions
Toggle the effect off and on to hear the difference.
✅ 結果: Rough audio files now sound like planned studio takes.
💡 プロのヒント: Keep the slider near 70 percent, since full strength can hollow out a deep voice.
How to Use Descript Filler Word Remover
フィラーワードの削除 lets you delete every um and uh across a recording with one click.
Descript tags filler words in the transcript automatically. One click clears them from the whole project instead of hunting through a waveform.
Step 1: Open the Edit Menu
Choose Remove Filler Words from the editing tools.
Step 2: Review the Highlights
Descript underlines each filler word it found in the script.
これがその様子です。
✓ チェックポイント: The word count drops and the pacing tightens noticeably.
Step 3: Remove Them All
Confirm the removal, then spot check two or three sentences.
✅ 結果: A rambling take turns into a clean cut without manual trimming.
💡 プロのヒント: Leave a few natural pauses in podcasts, because zero filler words can sound robotic.
How to Use Descript Multitrack Editor and Collaborator
Multitrack Editing and Collaboration lets you edit separate audio tracks for each guest and share the project with your team.
Every speaker keeps separate audio tracks, so you can duck one mic without touching another. Teammates can open the same project and comment in real time.
Step 1: Import Every Track
Drag and drop each guest recording into one composition.
Step 2: Label the Speakers
Assign names so the transcript splits cleanly by person.
これがその様子です。
✓ チェックポイント: Each speaker shows on their own lane in the timeline.
ステップ3：チームメンバーを招待する
Share a link and set edit or comment access for each person.
✅ 結果: Multi guest video projects stay organised from raw files to final cut.
💡 プロのヒント: Business accounts add single sign-on, which is worth it once more than five 編集者 share the account.
Descriptスクリーンレコーダーの使い方
スクリーンレコーダー lets you capture screen recordings and webcam video without a second app.
The built in screen recorder captures your display, mic, and camera together. Each source lands as its own layer for editing.
ステップ1：記録パネルを開く
Click New Recording and pick screen, camera, or both.
Step 2: Hit the Record Button
Press the record button and run through your demo.
これがその様子です。
✓ チェックポイント: Your screen recording appears in the project with a ready transcript.
ステップ3：停止して書き起こす
End the video recording and Descript starts the transcript on its own.
✅ 結果: A tutorial goes from capture to editable script in under two minutes.
💡 プロのヒント: Record at 1080p for tutorials, since text on screen turns mushy at lower settings.
Descriptオーバーダビングの使い方
オーバーダビング lets you patch a mistake mid sentence without re-recording the whole clip.
Overdub is the repair tool that sits on top of voice cloning. It swaps a wrong number or name inside a finished audio file, and it doubles as text to speech in your own voice.
Step 1: Find the Error
Search the transcript for the wrong word.
Step 2: Type the Replacement
Select Overdub and type what you meant to say.
✓ チェックポイント: The corrected phrase plays in your cloned voice at matching volume.
Step 3: Check the Seams
Listen to the sentence twice and nudge the timing if needed.
✅ 結果: One wrong stat no longer costs you a full re-record.
💡 プロのヒント: Overdub short phrases only, because long generated passages lose natural emphasis.
How to Use Descript Automatic Transcriptor
自動転写 lets you automatically transcribe audio and video content in 22 languages.
Descript will automatically transcribe anything you upload, including German, Spanish, and French. Accuracy is strong, though names and heavy accents still need a read through.
ステップ1：ファイルをアップロードする
Drop in an audio or video file from your drive.
Step 2: Pick the Language
Choose from 22 supported languages before processing starts.
これがその様子です。
✓ チェックポイント: Timestamped text appears next to the waveform within a minute or two.
Step 3: Fix the Names
Use Correct Text to fix spellings the AIツール missed.
✅ 結果: You get a searchable script you can also publish as show notes.
💡 プロのヒント: Add proper nouns to the vocabulary list first, and transcription accuracy jumps on the next file.
How to Edit Descript AI Green Screen
AIグリーンスクリーン lets you remove your background with no physical green screen.
AI Green Screen cuts you out of a messy room in one click. Pair it with Eye Contact and a talking head clip starts to look deliberate.
Step 1: Select the Camera Layer
Click your webcam clip in the timeline.
Step 2: Apply Green Screen
Turn on the effect and choose a colour, image, or blur.
✓ チェックポイント: Your background swaps 即座に while you stay sharp in frame.
Step 3: Refine the Edges
Adjust the threshold until hair edges stop flickering.
✅ 結果: A kitchen table shoot passes for a planned set.
💡 プロのヒント: Even lighting on your face beats any slider, so face a window before you hit record.
プロのコツとショートカットを紹介
After two years of daily editing, these are the shortcuts I actually use.
キーボードショートカット
| アクション | ショートカット |
|---|---|
| Play or pause | 空間 |
| Split at cursor | Cmd / Ctrl + E |
| Ignore selected text | Cmd / Ctrl + Shift + E |
| Start a new recording | Cmd / Ctrl + Shift + 2 |
ほとんどの人が見逃す隠れた機能
- Underlord: その アシスタント editor takes plain language prompts, drafts social posts, and generates B roll. Descript markets it as apocalyptic power at inhuman speed, which is marketing, but it is quick.
- Eye Contact: Redirects your gaze to camera when you were reading a script, so a scripted take still feels live.
- Timeline export: Send an XML to Final Cut Pro or Premiere when a client wants colour grading elsewhere.
- Animated キャプション: Pull captions and overlays straight from the transcript to lift video content on social.
避けるべきよくある間違いを説明する
Mistake #1: Editing before you fix the transcript
❌ 間違い: Cutting clips while names are still spelled wrong in the script.
✅ 右: Correct the transcript first. Every later edit points at the right words, and your captions ship clean.
Mistake #2: Running Studio Sound on everything
❌ 間違い: Applying full strength Studio Sound to music beds and room tone.
✅ 右: Use it on voice only. Music processed as speech turns thin and warbly fast.
Mistake #3: Exporting before checking the free plan limits
❌ 間違い: Finishing a long video, then finding the export is capped at 720p.
✅ 右: Check your tier first. The free plan gives one watermark free video export per month at 720p.
トラブルシューティングの説明
Problem: Transcription accuracy drops on interviews
原因： Two people on one mic, heavy accents, or background noise in the room.
修理： Record separate audio tracks per speaker, run Studio Sound to remove background noise, then transcribe again.
Problem: Voice cloning sounds flat
原因： Training audio was recorded on a different mic or in a louder room.
修理： Retrain with ten clean minutes from your usual setup, and keep overdubbed patches under one sentence.
Problem: Exports fail or stall
原因： A 4K video recording プラスAI effects can exhaust local memory during rendering.
修理： Close other apps, export at 1080p, or split long video projects into shorter compositions.
📌 注記： If none of these fix your issue, contact Descript support through the in app chat.
