Micro gestures make its AI generated videos feel closer to a real person.
Watch how the studio handles a script from start to finish.
🥈 準優勝：DeepBrain AI
Pick this one if realism matters more than reach. Start free, then move up when you need longer video clips.
DeepBrain AIの価格設定
DeepBrain AI keeps a free tier, which Synthesia does not. Here are the plans.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | 月額0ドル | Testing your first AI video |
| 個人的 | 月額24ドル | Solo creators making promotional videos |
| チーム | 1席あたり月額55ドル | Shared workspaces and review cycles |

機能比較
Here is the side-by-side view before we get into detail. We compare nine key features, then pricing.
| 特徴 | シンセシア | ディープブレインAI |
|---|---|---|
| 開始価格 | 月額18ドル | 月額24ドル |
| 無料プラン | ❌ | ✅ |
| 言語 | 140+ | 80+ |
| カスタムアバター | ✅ | ✅ |
| ビデオテンプレート | ✅ Extensive library | ✅ Smaller set |
| PowerPointから動画へ | ❌ | ✅ |
| スクリーンレコーダー | ✅ | ❌ |
| インタラクティブビデオ | ✅ Branching | ✅ Real-time avatar |
| 最適な用途 | Training and marketing videos at scale | News-style and high-realism video content |
1. AIアバター
シンセシア： The roster of diverse AI avatars is the headline here. Presenters cover a wide age and ethnicity range, and paid tiers let you record your own avatar. Delivery is clean and consistent rather than dramatic.
ディープブレインAI： Realism is the priority, and customization options cover skin tone, outfit, and framing. Its AI driven avatars use micro gestures that make communication feel human, which is why the studio shows up in news broadcasting. Custom avatars are available, and you control the avatar’s appearance during setup.
2. テキスト読み上げとAI音声
シンセシア： The text to speech feature spans 140+ languages and accents. Pronunciation controls let you fix names and product terms before rendering.
ディープブレインAI： Its AI voices cover 80+ languages with strong emotional range in English and Korean. Fewer options, but the pairing between voice and avatar is tight.
3. ビデオテンプレート
シンセシア： An extensive library of video templates covers onboarding, sales, and how to videos, which keeps professional videos consistent. Brand kits push your fonts and colours into every scene automatically.
ディープブレインAI： Templates lean toward news desks, product explainers, and promotional videos. The set is smaller, so heavy template users will notice the gap.
4. Video Editing and Generation
シンセシア： The built-in video editor handles trimming, layering, and scene reordering. You rarely need a second tool for light video editing work.
ディープブレインAI： Text to video generation is the core of the workflow. Editing tools are lighter, so complex cuts still move to an outside editor.
5. Collaboration and Teams
シンセシア： Shared folders, comments, and approval flows keep the video creation process organised. Larger content teams get the most out of this.
ディープブレインAI： Team workspaces handle roles and shared assets well. Per-seat billing means you pay more as the group grows.
6. AI Assistants and Scripts
シンセシア： Its AI video assistant turns a link, a doc, or a prompt into a first draft. That draft is a real starting point, not a blank timeline.
ディープブレインAI： The script assistant focuses on the words rather than the whole video. It shortens, rewrites, and paces your copy for spoken delivery.
7. Screen Recording vs PPT to Video
シンセシア： The AI screen recorder captures your screen and drops an avatar beside it. That combination suits software walkthroughs and support content.
ディープブレインAI： PPT to video takes an existing deck or PDF and narrates it. If your source material already lives in slides, this saves an entire step.
⚠️ 警告： These two features do not overlap. Pick based on where your content already sits: on screen or in slides.
8. Translation and Multilingual Reach
シンセシア： One click duplicates a finished video into another language, lip sync included. For teams serving diverse global audiences, this is the strongest argument in the whole comparison.
ディープブレインAI： Video translation works well across its 80+ languages. Coverage is narrower, though quality holds up in the major markets it supports.
9. Interactive Video and Integrations
シンセシア： Interactive videos add quizzes and branching paths. Pair that with LMS platforms and you get trackable corporate training modules.
ディープブレインAI： Its interactive AI human answers questions in real time. That fits kiosks and customer service far better than a linear training module.
10. 価格設定とコスト
Both AI powered platforms sell subscriptions. Market entry pricing for AI video generators often sits near $30 a month, so both land under that mark.
| ティア | シンセシア | ディープブレインAI |
|---|---|---|
| 無料 | ❌ | 無料：月額0ドル |
| エントリ | スタータープラン：月額18ドル | 個人向け：月額24ドル |
| 中 | クリエイター：月額64ドル | チーム：1席あたり月額55ドル |
| トップ | 企業向け：カスタム価格設定 | 企業向け：カスタム価格設定 |
シンセシア： Starter is $6 cheaper than DeepBrain AI’s entry plan. Creator is a flat $64/month no matter how many people touch the account, which matters for teams.
ディープブレインAI： The $0 tier is a real advantage for anyone testing AI video generation for the first time. Team at $55 per seat becomes the pricier option past two users.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |

💰 あなたの予算
Synthesia costs less to start at $18 a month. DeepBrain AI carries a higher price point at entry but lets you try it at zero cost first.
🔌 あなたの技術スタック
If your material lives in slides, DeepBrain AI’s deck import wins. If you need LMS-friendly training videos with tracking, Synthesia fits better.
📝 あなたのコンテンツスタイル
Marketing videos and explainer videos suit Synthesia’s template-driven approach, which leaves room for creative expression. Anchored, formal delivery suits DeepBrain AI’s realism.
🎓 あなたの経験レベル
Beginners get to a finished video faster in Synthesia. DeepBrain AI rewards users who care about fine control over the avatar and pacing.
🆓 無料トライアルとデモ
DeepBrain AI’s free tier lets you generate videos before spending. Synthesia limits you to a sample clip, so plan a paid month to evaluate it properly.
🛟 サポートオプション
Both offer email and help centre support on paid plans. Enterprise buyers on either side get a named contact and onboarding help.

私たちのレビューで取り上げられなかったこと
We focused on individual creators and small teams making standard video content. We did not test enterprise SSO, kiosk hardware deployments, or API-level オートメーション on either platform. Custom pricing based on seat count was outside our scope too. If you run broadcast workflows or manage 50+ seats, your results will differ from ours.

最適な用途: Corporate training, multilingual marketing videos, product marketing videos, and software how to videos.
These two products chase different goals. Synthesia is a video creation tool built for efficient video creation at volume, and it holds up when you need compelling videos across many markets.
DeepBrain AI is built for realism. Its hyper-realistic presenters and interactive AI human make it a valuable tool for broadcast and customer-facing screens.
If your priority is one script reaching many markets, take Synthesia. If a single avatar has to carry a serious message on camera, DeepBrain AI earns the spend.
