Organise bilingual captions for iCouldPlay in one paired file

Bilingual viewing need not require two simultaneously enabled tracks. For your own clip, put original and translation inside each cue in one file. Start with working simple captions, add translations externally and check in iCouldPlay. This does not promise in-app automatic translation or subtitle merging.

Start with an accurate short monolingual sample

Choose three to five self-authored cues with verified words and timing. Fix original errors before adding translation so language, timing and styles are not changed together. Use authorised material and retain an unchanged monolingual original for comparison.

Record the corresponding event for each cue to avoid pairing a translation with neighbouring dialogue. Preserve negatives, numbers and conditions and investigate uncertain terms in context. Accurate meaning and tidy line layout need independent checks.

Pair two lines within one cue

In a plain-text editor, put original first and translation second under the same start and end times. Preserve required blank separation between cues. Use an already verified simple format such as VTT without adding complex positioning for this small exercise.

Keep language order consistent according to your preference. Identify speakers explicitly if simplified styling loses that distinction. Do not distort original meaning merely to force a two-line appearance; each cue should remain complete and predictable.

Allow adequate reading time

Translations may be longer than originals. Rephrase at natural boundaries and adjust your own cue intervals where appropriate without extending into another speaker's content. Judge actual readability rather than prescribing a universal word count or equating visible text with sufficient reading time.

Remove unnecessary repetition while preserving meaning. If still dense, maintain separate monolingual study and bilingual close-reading copies with clear purposes rather than endlessly shrinking text. Captions should support understanding without hiding essential demonstrations.

Select this single bilingual file

Save a clearly named local revision and load it through available controls, verifying selection instead of the old file or disabled captions. For extra words, inspect baked-in text and other selectable tracks before blaming the new file's layout.

This uses two lines in one file, independent of parallel-track support. Verify a short cue before a long one. Filename and language labels are identification aids; read actual words to establish the bilingual version loaded correctly.

Check actual viewing size

Watch three cues in your usual phone or tablet position and verify natural pairing. For tiny text, inspect length and available area before adjusting actual style controls. Paused enlargement does not establish readability at normal playback speed.

If captions hide actions, inspect available placement controls and consider shorter wording. Change one factor at the same scene rather than size, placement and video ratio together. Recorded words and external captions follow different framing rules; stretching the entire picture does not resolve every overlap.

Recheck language and timing at three positions

Inspect beginning, middle and ending, listening to the original before reading the translation. Check for missing lines or copied prior text. Both lines in an interval should address the same event. Retain these fixed checks when extending the file to expose later editing shifts.

Recheck after video cuts. Removing an introduction and cutting a middle passage affect timing differently, so one global offset may not suffice. Keep monolingual and bilingual originals and revise copies under clear edition identities.

Retain editable material

Archive video edition, monolingual original, bilingual copy and a short result note, including language order and use. Check video and subtitle files independently offline through reopening, beyond cached pages or visible list entries.

Completion means matched meaning, suitable intervals, consistent order and readable normal-size lines. Preserve this simple file when adding effects later, without making unverified automatic translation, dual-track rendering or font installation prerequisites for the task.
