FAQ from AddSubtitle
What is AddSubtitle?
AddSubtitle is an intelligent, all-in-one video localization platform designed for speed without sacrifice. It unifies subtitle creation, AI voice synthesis, multilingual translation, and voice cloning into a single, cloud-native interface — empowering creators to publish globally in minutes, not days.
How to use AddSubtitle?
Upload your source media (MP4, MOV, MP3, or YouTube link), select your goal — e.g., “Add Spanish Subtitles” or “Dub into Japanese with My Voice” — configure preferences, and launch processing. Then refine results in the editor: adjust caption timing by dragging words, toggle between voice options per scene, add dual-language overlays, or export ready-to-publish files in seconds.
Why is AddSubtitle different from other online video editors?
Most tools handle *one* function well — subtitles *or* voiceover *or* translation. AddSubtitle handles all three *simultaneously*, with shared context: your translated script informs voice pacing; your cloned voice adjusts to translated phrasing; subtitles auto-resize to match spoken duration. It’s not a suite of tools — it’s a cohesive video intelligence layer.
How many languages does your AI video translator support?
We support translation and dubbing into **65+ output languages**, including Arabic, Hindi, Portuguese (Brazil), Korean, Vietnamese, and Russian — with over 110 input language options. Our AI understands dialectal variations and domain-specific terminology (e.g., medical, legal, tech), ensuring accurate, natural-sounding output.
Do I need to download any software to use this video editor?
No. AddSubtitle runs entirely in your browser — no plugins, no installers, no storage overhead. Works on Windows, macOS, Linux, Chromebooks, and iOS/Android tablets. Your projects, settings, and voice clones are securely synced across devices via your account.
Can I add multi-language subtitles to a single video?
Yes — effortlessly. Generate and display up to three subtitle tracks simultaneously (e.g., English original + Spanish translation + French translation), each fully editable, stylable, and independently timed. Ideal for international conferences, educational content, or accessibility-first publishing.
Does AddSubtitle offer mobile compatibility?
Fully responsive design ensures seamless use on smartphones and tablets. While advanced editing is optimized for larger screens, core workflows — uploading, translating, previewing, and exporting — work flawlessly on mobile browsers. A dedicated iOS/Android app is scheduled for Q4 2025.
Is this video translator free to use?
Yes — start with our free tier, which includes 30 minutes of processing per month, access to 20+ AI voices, and basic translation. Paid plans unlock unlimited processing, premium voices, voice cloning, API access, and priority support — all with transparent, no-lock-in pricing.
How secure are my videos and data using your video editor?
Your content is encrypted in transit (TLS 1.3) and at rest (AES-256). Uploaded files are automatically deleted from servers within 72 hours unless saved to your project library. Voice clones are never shared or used to train third-party models. We comply with GDPR, CCPA, and SOC 2 Type II standards — and undergo annual third-party security audits.
