The hardcoded subtitle problem

A new subtitle trackcannot replace textalready in the frame

When source subtitles are burned into the video pixels, adding translated captions simply stacks a second layer on top. The source text has to be cleared before the translated version is rendered.

Frame-level problem

The original subtitle is already part of the video.

A separate subtitle track cannot hide pixels that were burned into the source frames.

Source pixelsReplacement layer

Burned-in text is part of every frame

01

Hardcoded subtitles remain visible even when a separate translated subtitle track is added.

Overlaying creates double subtitles

02

A new subtitle placed over the source language can make a useful product demo feel unfinished.

Replacement needs a clean export

03

To replace original subtitles in product videos, the layer must be cleared, translated, rebuilt, and exported as one usable video file.

Visual translation

A broad market term for changing visible text inside a video.

02

Video localization

Adapting a video for viewers in another language or market.

03

Subtitle localization

Relayvid's focused workflow for removing, translating, replacing, and exporting subtitles.

Inside the workflow

The subtitle layer ishandled in four passes

The product footage stays in place while the visible source text is removed and rebuilt for the target language.

STEP 01

Upload the source video

Start with the product video that contains the source-market subtitles.

STEP 02

Remove the hardcoded subtitle layer

Remove hardcoded subtitles from product videos before adding the translated layer.

STEP 03

Translate the subtitle text

Translate hardcoded subtitles in product videos into the target language for the new version.

STEP 04

Replace, mute, and export

Render the translated subtitles into the video and export a muted MP4.

What changes / what stays

Keep the product video.Change the subtitle layer.

Relayvid is not a full editor. It preserves the source product footage while targeting the visible source subtitles and the audio state required for a muted export.

What Relayvid handles

The product footage stays in frame

The product, packaging, and demonstration remain the source of the finished video.

The source subtitles are replaced

The workflow targets the embedded source subtitle layer instead of covering it with a second language.

The audio is muted at export

The result is a muted MP4 suited to product-video reuse without source-market audio.

Best fit and scope

Use it for subtitlereplacement with clear inputs

Relayvid's current MVP is focused on one visual problem: replacing embedded source subtitles in short product videos.

Good inputs

  • Hardcoded subtitles with a relatively stable position
  • Short product demos with a simpler background behind the subtitles
  • Source videos that already show the product clearly

Not included

  • Dubbing, voiceover, or lip-sync
  • A full video editing timeline
  • A promise to translate arbitrary animated scene text

Output file

The final asset is a muted product video for ecommerce listings: it keeps the product footage and carries the translated subtitles as rendered text in an MP4. The output is a file you can reuse, not a new editing timeline to finish.

FAQ

Answers aboutthe subtitle layer

What does visual translation mean for a product video?

Visual translation is a broad term for changing visible text inside a video. Relayvid applies that idea to a focused subtitle localization workflow: remove the source subtitle layer, translate the message, and render the replacement.

How does Relayvid remove hardcoded subtitles from product videos?

Relayvid targets source subtitles that are already embedded in the video frames, clears that visible layer, and prepares the video for translated subtitles.

How does Relayvid translate and burn in subtitles for product videos?

Relayvid translates the source subtitle message, removes the original hardcoded layer, and burns in the translated subtitles before exporting the product video.

How does Relayvid replace original subtitles in product videos?

The workflow clears the original subtitle layer from the video frames before rendering the translated subtitle layer in its place.

What happens to the original audio after subtitle localization?

The exported result is a muted MP4. Relayvid focuses on changing the visible subtitle layer, not on dubbing or translating the source audio.

What should I check before uploading a video?

Check that the subtitle position is relatively stable, the background behind it is manageable, and the product remains clearly visible throughout the video.

Does subtitle localization include dubbing or animated scene-text translation?

No. Relayvid focuses on embedded subtitle replacement and muted MP4 output rather than audio translation, dubbing, voiceover, lip-sync, or arbitrary animated scene text.
