Some media carries words or a voice — a talking-head video, a screenshot with a caption on it, a worksheet. For these you can upload a different file for each language, and Makeshapes plays whichever one matches the session's language.
Language versions are for alternative files: a re-shot video, a localized screenshot, a translated PDF. If the picture is the same and only the words differ, subtitles or a dubbed audio track usually work better. Those stay on the original asset as extra tracks rather than becoming separate versions. See Subtitles and Dub audio into other languages.
Add a version
Open the media item from your media library, or click it in the experience.
Scroll to Language versions.
Click Add version.
In the dialog, choose the Language and add the File.
Click Add language version.
Video and audio take a few minutes to process. The version shows Processing… in the list until it's ready, and the list updates on its own.
Preview each version
The Language versions list is also the preview picker. To preview a version, select its row in that list, and the player switches to that file. The player also has a matching control that names the language, such as Previewing French, so you don't have to scroll back and forth.
The first row is always the base language file, marked (base language). That's the file used for any language you haven't uploaded a version for.
See coverage across the whole experience
Checking assets one at a time gets slow. Instead:
Open the experience and go to Translation.
Switch to the Media view.
Every media slot in the experience is listed, grouped by section and activity, with a card per language showing the file that will actually play. A card that says Plays the English file or Shows the English image is falling back to the English file. To add a version for that asset and language, click the amber + on the card.
To see only the rows still missing something, turn on Only untranslated.
Two things worth knowing
Regional languages match loosely in one direction. A Spanish file covers a Spanish (Argentina) column, but a Spanish (Mexico) file does not — it only covers Spanish (Mexico).
Shared Makeshapes media can't have your own language versions. Fork a copy into your library first, then add versions to the copy.
Delete a version
To delete a version, click Delete on its row, and then click Yes, Delete. If the file is in use in an experience, Makeshapes tells you it can't be deleted. Remove it from the experience first.
