Translating Your YouTube Titles and Descriptions Alongside Subtitles

What translated metadata does on YouTube

YouTube lets you attach a title and description per language to a single video. A viewer whose interface language matches sees the translated version in search results, on the watch page and in recommendations; everyone else sees your original. The video itself is unchanged.

Translated metadata, translated subtitles and a dubbed audio track are three separate layers. You can add any of them without the others, but they work best together. A Spanish title that leads to a video with no Spanish subtitles and no Spanish audio promises something the video cannot deliver, and viewers notice within seconds.

YouTube Studio's layout for adding translations has changed over the years; it currently lives on the video's languages or subtitles page, and YouTube Help documents the exact steps. Set the video's original language first, because that setting is what the translations are attached to.

The gap mydubly leaves, and how to fill it

mydubly translates speech. From one run you get a translated transcript and translated SRT and VTT subtitles, and in full output a dubbed track as well. It does not write or translate your title, description, tags or thumbnail text; you handle those yourself.

The useful part is that the translated transcript is a ready-made glossary. It shows exactly how your product names, techniques and recurring phrases were rendered in the target language. Using the same terms in the title and description keeps the metadata consistent with the subtitles, so the viewer who searched for a phrase hears or reads that phrase in the video.

A workflow for one video

1. Generate translated subtitles for the video in the subtitle generator. Transcript mode costs 1 credit per minute, so a 15-minute video is 15 credits per language.
2. Skim the translated transcript and note how key terms were translated. Fix any that are wrong in the SRT before you upload it.
3. Draft the translated title and description using those terms, either yourself, with a translation tool, or with a fluent collaborator.
4. Check the draft against real searches in that language (next section) and adjust the wording.
5. In YouTube Studio, add the language, paste the title and description, and upload the SRT as that language's subtitles.
6. Watch the first minute with that subtitle track on, to confirm the title and the opening match.

Keyword research in another language without inventing data

You do not need paid tools or volume estimates to avoid obvious mistakes. A few free checks catch most of them:

• Type the translated topic into YouTube search with your interface language set to the target language and read the autocomplete suggestions. They show phrasings people use.
• Look at the titles of videos that already rank for the topic in that language. Note which words recur, not their view counts.
• Ask whether people searching in that language use the English term. Many software and gaming terms are searched in English even by viewers who prefer another language.
• If your channel has access to YouTube Analytics' research features, see which searches lead viewers in that region to your existing videos.

Write down the phrase you chose and why, so the next video in the series uses the same wording. Consistency across a playlist matters more than squeezing one more keyword into a single title.

Before and after: a literal title vs a researched one

The second version is only better if the video actually covers reviving a neglected starter. Titles must describe the content; YouTube's policies treat misleading metadata as a problem, and a mismatch costs you viewer trust either way.

Descriptions, chapters and links

Descriptions carry more than a summary. When you translate one, handle each part deliberately:

• The first two lines show in search and above the fold, so translate them with the most care.
• Chapter timestamps stay exactly as they are; translate only the labels next to them. YouTube Help lists the formatting rules chapters must follow.
• Links to other videos can point to the same videos, since translated metadata travels with them. Links to your website should go to a page in that language if you have one.
• Sponsor copy may have rules about wording; check with the sponsor before translating their message.
• Hashtags are worth translating only if people in that language actually use the translated tag.

YouTube applies character limits to titles and descriptions. Translations into many languages come out longer than English, so a title that fits in English may need trimming. Check the current limits in YouTube Help rather than relying on a number you saw years ago.

Common mistakes and limits to watch for

• Machine-translating the title and pasting it unread. Titles are short, so a single wrong word changes the meaning.
• Translating brand or product names that should stay as they are.
• Promising content in the title that only exists in the original language, such as on-screen text mydubly does not translate.
• Leaving the thumbnail text in English while the title is in Japanese; the thumbnail is often read first.
• Assuming translated metadata guarantees reach. It can help the right viewers find and understand a video; it does not override how well the video holds attention.

How mydubly supports the metadata work

mydubly's part is the speech: the translated SRT for subtitles, the translated transcript you mine for terminology, and optionally a dubbed track through AI dubbing. It runs on files you upload from your device, supports 21 languages, and detects the spoken language automatically. The titles, descriptions, tags and thumbnails stay in your hands, which is where judgment about your audience belongs anyway.

Where to go next

Pick one evergreen video, produce translated subtitles in the subtitle generator, and write its translated title and description with the terms from the transcript. If you are also planning dubbed tracks, read YouTube multi-language audio next.
