> **Quick answer —** News video on social plays muted, so subtitles carry the story rather than support it. Shorter lines, faster cuts and a first line that works alone matter more than translation quality alone.[Vitra.ai Universe](https://www.vitra.ai/features/document-translation) turns one story into every edition.

## Muted by default

Social video autoplays without sound, and news video is watched in feeds more than on news sites. So the subtitle is not an accessibility addition to the audio. It is the primary channel, and the audio is the supplement. That inverts the usual priorities.

## What changes for feed video

Element

Broadcast convention

Feed convention

Line length

Up to 42 characters

Shorter, often 30

Lines on screen

Two

One or two, larger

Reading speed

Measured

Faster, viewers scroll

First card

Establishes context

Must stop the scroll

Burned in or sidecar

Sidecar

Both, for different reasons

The first line is doing a headline's job. If it does not make the viewer stop, nothing after it is read, and translating the source's first line faithfully usually produces a weaker opening than composing one.

## Burned-in versus sidecar, honestly

For [social](https://www.vitra.ai/solutions/ai-ugc-content) distribution, burned-in subtitles are frequently the pragmatic choice, because platform caption support varies and a re-uploaded clip loses its sidecar file.

The cost is that burned-in text cannot be swapped per language without re-rendering, and it is invisible to search. So the working answer is both — a sidecar for the site and for [discovery](https://www.vitra.ai/general/multilingual-video-seo), and burned-in versions rendered per platform where they are needed.

[Image translation](https://www.vitra.ai/features/image-translation) handles on-screen furniture, lower thirds and name supers that a caption file never touches.

## Accuracy under time pressure

Names and figures again, plus one specific to video: what is on screen must match what the subtitle says.

A subtitle describing a location while the footage shows another is a correction, and it happens when a clip is recut after the subtitles were written.

Run [quality control](https://www.vitra.ai/features/quality-control) on the rendered clip rather than the transcript, and keep terminology in [memory](https://www.vitra.ai/features/translation-memory) so a name matches the [wire copy](https://www.vitra.ai/news-media/wire-copy-translation) that ran alongside it.

## FAQ

**Why do news videos need subtitles rather than dubbing?** Because social video autoplays muted and is watched in feeds. The subtitle carries the story and the audio supplements it, which inverts the usual priority between the two.

**How do social subtitles differ from broadcast subtitles?** Shorter lines, larger type, faster reading speed and a first card that has to stop the scroll. Broadcast conventions assume a viewer who has already committed to watching.

**Should news subtitles be burned in or a separate file?** Both, for different jobs. Burned-in versions survive re-uploads where platform caption support varies; a sidecar file stays swappable per language and is readable by search.

**What goes wrong when a clip is recut?** Subtitles stop matching the footage. A line describing one location over shots of another is a correction, which is why checks should run on the rendered clip rather than the transcript.
