Subtitle translation

Subtitle translation expresses caption meaning in another language while preserving context, role and a readable timed presentation.

Subtitle translation expresses the source content in another language. It must preserve the meaning of the scene and provide a useful timed reading presentation, rather than merely replace words independently.

Dialogue can be split across several cues. A pronoun, an incomplete phrase or an ambiguous word can need context from the neighboring cues and the picture.

Cue boundaries are not sentence boundaries

Consider an invented English line mentioning “the bank”. The scene can make that a river bank or a financial institution. A translation system using only those two words has less evidence than a translator considering the surrounding dialogue and scene.

A sentence split into two captions has the same problem. Translating each fragment independently can select incompatible wording, repeat material or lose the intended reference.

Retain enough surrounding context, then decide how the translated sentence should be distributed into cues. That distribution need not preserve every original line break.

The translated length can change

A cue with unchanged start/end retains its available reading interval. A longer translated sentence can require different wrapping, condensation or timing decisions.

For an invented cue lasting 2.5 seconds, a 40-character translation has 16 characters per second under that simple counting convention. A 70-character version has 28. These are descriptive example rates, not universal readability limits or a substitute for considering script, audience and scene.

Property Translation question
Meaning Are negation, names, numbers and intent preserved?
Cue interval Does the text appear with the relevant scene/speech?
Length and breaks Can the intended audience read the presentation?
Language/script Does the output identify and encode the intended text?
Content role Are sound/speaker descriptions retained where required?

Changing the target language label does not change the bytes or prove that the translated wording is correct.

Accessibility content also needs translation

A selected SDH track can contain dialogue, speaker labels and meaningful sound descriptions. Removing the descriptions because they are not spoken changes the resource's purpose.

Likewise, a forced-passage resource should remain the intended subset unless a fuller track is deliberately authored. Translation and content selection are independent decisions.

Names and quoted text can also retain another script inside the target language. Bidirectional rendering, Unicode and suitable fonts remain part of the presentation.

For Emby, the translated file needs a truthful language/role association and matching edition timing. The automatic/manual download or authoring route supplies a resource; reviewing its content and presentation establishes the translation the viewer actually receives.
