Problem
Original subtitlesmake product videoshard to reuse
When hardcoded (burned-in) source-market subtitles stay on screen, buyers may not understand the product video, and the asset can feel unfinished in a new market.
Buyers miss the message
Source-language subtitles make a useful product demo harder to understand.
Source-market text hurts trust
Foreign-language subtitles can make product pages and ads feel less local.
Manual editing slows testing
Removing subtitles, translating the text, styling, and exporting each video slows testing.

FAQ
Clear expectationsbefore you upload
What kinds of product videos work best for subtitle localization?
Relayvid works best with product videos where subtitle areas stay relatively stable and the background behind the subtitles is not overly complex.
Can Relayvid translate hardcoded subtitles in product videos?
Yes. Relayvid is designed to remove source subtitles that are already embedded in the video where possible, then replace them with translated subtitles. Videos with stable subtitle placement and simpler backgrounds tend to produce cleaner results.
Do I need an API key or to install anything?
No. You do not need an API key or to install anything. Access Relayvid through your browser.
What happens to product or package text?
Relayvid is designed to preserve commercially relevant product text while replacing source-market on-screen subtitles.
What happens to the original audio?
The MVP is designed to export a muted MP4 so the video can be reused in ecommerce placements where sound is not needed or should not be used.
Does Relayvid translate video audio or provide dubbing?
No. Relayvid focuses on subtitle localization and muted MP4 output for ecommerce use rather than audio translation, dubbing, or lip-sync.
