5 Risks and Mitigations

• AI caption accuracy / proper nouns: misreads of names / places / technical terms - Submagic frequently turns "Sora" into "Soda"; Captions has weak Japanese accuracy. Mitigation: register vocabulary in Submagic, use Otter Custom Vocabulary, use Rev human transcript $1.50/min for critical videos, compare multiple AIs, always have a human review captions before publishing.
• Multilingual translation nuance loss: VEED 100 languages depend on Google Translate, leading to mistranslated business terms; Captions 26 languages benefit from DeepL backup; Japanese-to-English honorifics lose nuance. Mitigation: use DeepL Pro translation alongside, sync HeyGen Translate AI voices, have professional translators review key videos, compare with ChatGPT translation.
• Video file upload / privacy: uploading confidential meeting / medical / legal videos creates GDPR/HIPAA violations; Otter / VEED default to cloud processing. Mitigation: Otter Business SOC2 Type II, prefer local processing (CapCut Desktop / Descript Local), Rev SOC2/HIPAA, download confidential video then edit locally.
• AI Voice / AI Avatar misuse / misinformation: Descript Overdub voice cloning, Captions AI Avatar, deepfake concerns, US FTC / EU AI Act regulation. Mitigation: require consent, display CDC watermarks, disclose AI usage, use Adobe Content Credentials, verify commercial licensing.
• Subscription cost stacking: Submagic $16 + Captions $25 + VEED $25 + Descript $30 + Otter $20 + Rev $15 = $130/mo - heavy for individual creators. Mitigation: pick 1-2 tools per use case (TikToker = Submagic + free CapCut, YouTuber = VEED + HeyGen, Podcaster = Descript + Otter), use annual contracts for 20-40% off, combine with free plans, ScreenPal as a free alternative.
