Why do translated product subtitles no longer fit the clip?
Translate the meaning, then review the subtitle as timed media. A longer sentence can exceed both the available space and the time a viewer has to read it. Do not fix every overflow by shrinking the type until the subtitle becomes unreadable.
Compare the translated message with the action
For a fictional travel-case clip, a short English line may expand in another language while the case closes quickly. Record the action interval and the necessary product meaning. Identify which words can be simplified and which qualifiers must remain to preserve accuracy.
A translated slogan and a translated spoken-caption track are different editorial tasks. If the subtitle represents narration, keep it faithful to the final localized audio. If it is added campaign copy, keep that distinction clear.
Make a timed-language worksheet
| Element | Check | Possible repair |
|---|---|---|
| Essential claim | Meaning and qualification | Careful shortening |
| Reading interval | Enough time at normal speed | Longer hold or edit |
| Text placement | Product action remains visible | Reposition overlay |
| Audio caption | Matches localized audio | Correct transcription |
Use a reviewer who understands the target language. Counting characters alone does not determine readability across writing systems.
Adapt the edit if needed
A longer static hold or a separate explanatory panel may be better than extreme compression. Make the change in an external editor and inspect the final clip. Do not reverse or retime an action in a way that changes its meaning merely to create subtitle space.
Approve in the destination
Watch the localized export on a phone with the destination controls visible. Ask the reviewer to explain the complete message after one normal playback. Use translation layout review for still images and retiming boundaries for the edit.
Keep the condition when the line becomes longer
Fictional approved campaign meaning: “Fits two slim bottles; bottles not included.” A target-language version is harder to read during the short closing action. Dropping the exclusion or changing two to three would alter the offer. This is a writing exercise with no actual translation, audio or timed reader test.
| Text role | Review against | Repair boundary |
|---|---|---|
| Campaign overlay | Approved product facts and complete translated meaning | Simplify wording without losing the condition |
| Caption of narration | Actual final localized audio | Correct audio and caption together if the claim is wrong |
| Timing | Final edit at normal playback in the destination | Use a suitable hold/panel rather than a tiny font |
Ask a qualified language reviewer to explain the full meaning after normal playback, including the condition. Character counts alone cannot establish readable timing across languages. If the edit changes, repeat the timing check on the exact new export. Keep approved language, audio, subtitle and edit identities together; do not reverse a meaningful action merely to create reading time.
