Why did one subtitle language disappear when I exported two languages together?

Inventory tracks before exporting

Record each language, its approved text, timeline track and delivery role. A translated track can exist but be disabled or unselected during export. Do not recreate the translation before checking whether the missing language was included in the actual export request.

Decide whether viewers should select one language, see both simultaneously, or receive separate video versions. Those choices require different delivery arrangements. A bilingual picture and two selectable subtitle files are distinct assets with different layout and accessibility checks.

Export and name languages independently

Adobe documents one stream per SRT sidecar file. For independently selectable English and Chinese subtitles, export the intended track to separate language files and keep the exact video revision attached. A template such as campaign-v03.en.srt and campaign-v03.zh-CN.srt is a naming example, not a claim that files have been generated. Putting both languages into one cue makes bilingual text in one stream; it does not create a two-language selector. Verify the receiving platform’s supported language assignment and file handling, then reimport and play each language with the actual video.

Reimport each file into a clean test with the exact delivery video. Check the opening, a middle cue and the ending for language, timing and product names. A file that opens in a text editor proves neither synchronization nor correct destination selection.

1. List approved languages and intended viewing behavior.
2. Mark the active caption track and actual export option.
3. Create clearly named language-specific delivery files.
4. Reimport each sidecar with the exact video revision.
5. Check selection, timing and wording at the destination.

Fictional exercise: the Chinese track is omitted

In this fictional exercise, a mug video has approved English and Chinese tracks. The operator exports only the active English sidecar. The missing Chinese file is an export-selection problem, not a translation-quality problem or an CartVisual generation result.

The operator exports the Chinese track separately and tests both files with the same video. If the destination cannot expose the intended language choice, the team asks its owner to approve another delivery arrangement. They stop when both agreed language outcomes are verified, not when two tracks exist in the project.

Protect language and version alignment

Keep a ledger connecting the video revision, subtitle file, language and review status. A later cut can invalidate both languages’ timing even when their words remain correct. Retain the old files for traceability but clearly remove them from the current delivery set.

Adding subtitles and uploading them are external postproduction tasks. Stop a language release if its sidecar is absent, associated with another edit or not playable as intended. CartVisual’s silent TVC creation does not establish caption tracks, translated timing or platform subtitle publishing.
