Video cleanup and localization FAQ

Questions creators ask before cleaning and localizing videos.

Direct answers about updating subtitles and owned text before translating, dubbing, and publishing localized videos.

Can I process any video?

No. UnmarkAI is only for content you own, license for editing, or are explicitly authorized to modify. Attribution, provenance, ownership marks, safety labels, evidence, and required notices must remain intact.

Can I translate Chinese videos to English?

Yes. Start with a Chinese source video, update hardcoded Chinese subtitles or on-screen text when needed, then create English subtitles, dubbing, and localized exports for global audiences.

Can UnmarkAI remove hardcoded subtitles?

Yes. UnmarkAI removes burned-in subtitles and fixed captions that are part of the video pixels, creating a cleaner frame before re-subtitling, dubbing, translation, or cross-platform publishing.

Does UnmarkAI support video dubbing?

Yes. The video translation workflow supports translated voiceover and dubbing review after the source frame is cleaned, so teams can check subtitles, voice timing, and delivery quality together.

Can I translate videos and keep subtitles from overlapping?

Yes. Removing old source-language subtitles first prevents them from colliding with new translated subtitles, captions, and market-specific layouts.

Can I remove text from a video before translating it?

Yes. UnmarkAI can clean on-screen text, lower thirds, review labels, and hardcoded captions from authorized videos before translation and localization.

What videos work best with UnmarkAI video translation?

The strongest fit includes short dramas, talking-head videos, tutorials, course videos, product demos, creator clips, and repurposed social videos that need subtitle cleanup, translation, dubbing, or multilingual delivery.
