Original subtitlesmake product videos hard to reuse

When source-market subtitles stay on screen, buyers may not understand the video and the asset can feel unfinished in the new market.

Buyers miss the message

Source-language subtitles make a useful product demo harder to understand.

Source-market text hurts trust

Foreign-language captions can make product pages and ads feel less local.

Manual editing slows testing

Masking, translating, styling, and exporting each video slows testing.

What you get

Relayvid turns one source-market product video into a muted localized MP4 in one flow, ready for product pages, listings, ads, and shorts.

  • Source-market on-screen subtitles removed
  • Translated subtitles burned into the video
  • Original audio muted for ecommerce reuse
  • Final MP4 ready for product pages, listings, ads, and shorts

Use cases

Built for the places sellers actually reuse product videos

Relayvid focuses on commerce workflows where translated subtitles, muted output, and a final MP4 matter more than an editor timeline.

Product pages

Use product demos where buyers need to understand the item quickly.

Product listings

Turn overseas product videos into localized assets for marketplace listings.

Ad creative tests

Repurpose winning short product videos without leaving old captions stacked.

Product shorts

Turn overseas product videos into cleaner localized short-form assets.

Why Relayvid

Most video localization workflows are heavier than sellers need

Approach
Subtitle overlays
Fast, but old subtitles still sit underneath the new text.
Manual editing
Flexible, but slow when every product video needs masking, translation, styling, and export.
Generic dubbing tools
Useful for speaker videos, but not built around muted product-page and listing reuse.
Relayvid
Remove on-screen subtitles, add translated subtitles, and export a muted MP4.

Quality and trust

Built for practical ecommerce reuse

Relayvid focuses on product videos that need quick subtitle localization, muted output, and a ready-to-use MP4 without manual editing.

Product-text aware

Product labels, package text, and subtitle overlays are handled differently.

Ready-to-use MP4

The output is aimed at product pages, listings, ads, and shorts without another editor workflow.

Best-fit video guidance

Videos with steady subtitle areas and simpler backgrounds are best suited for clean subtitle replacement.
