To compare a YouTube transcript with its translation, first check the original-language transcript against the audio, then compare the same complete claim in the translated text. Record whether a discrepancy begins in transcription or in translation. Damas supplies both kinds of editable, copyable text; the comparison and review record are manual work.
Prepare two texts from one source
Damas supports public, on-demand YouTube, Instagram and X video links up to 90 minutes. On iPhone, iOS 18.6 or later, internet, Premium and AI processing consent are required. Submit only material you have permission to process. Private, restricted and live videos are unsupported; a public source can also be inaccessible.
- Open the source and keep its link and title. Choose one claim you need to understand, including the sentence before and after it.
- Provide the supported link in Damas. Follow the current app instructions for original-language transcription and translation into your supported target language. Review the AI consent and wait for processing.
- Keep the original transcript and translation separately labeled. Translation is into 70 languages; the eleven interface languages are a different list. A built-in summary is a shorter overview, so use the full passages for this comparison.
- Replay the original passage. Check the words before judging its translation, particularly negatives, names, numbers and units. Do not guess an inaudible word from the translation.
- Locate the corresponding translated passage by its surrounding meaning. Paragraph breaks can differ. Copy the two passages into your own review note; no automatic alignment is implied.
Find where the discrepancy starts
Use a four-field record: audio check, original transcript, translated meaning and decision. Keep the unedited candidate wording alongside any correction so you can explain what changed.
If the transcript disagrees with audible speech, mark a transcription issue first. Correct your original-language note only when the recording supports it, then separately check whether the translated passage expresses that corrected meaning. Editing a note does not establish that another result has been regenerated.
If the transcript matches the audio but the translated claim differs, mark a translation issue. Compare who acts, what happens, whether it is affirmed or denied, how much, under what condition and with what degree of certainty. Different word order alone is not a meaning error. If you cannot assess the source language, leave the claim pending and ask a competent bilingual reviewer; agreement between two AI texts is not an audio check.
Fictional example: a limit becomes an instruction
This invented teaching example is not a quotation from a real video. Imagine a speaker says that a trial may include at most three documents, but only after permission. A candidate translation presents three documents as required and omits permission.
| Check | Meaning to retain | Reason to hold the candidate |
|---|---|---|
| Certainty | A trial is permitted, not ordered | Permission has become an obligation |
| Quantity | Three is an upper limit | The candidate requires exactly three |
| Condition | Permission comes first | The condition is missing |
Before correcting the translation, listen for all three elements in your actual source. If the original transcript already lost the condition, record that earlier error too. A polished replacement sentence cannot prove that the audio contains it. Do not add an approver, deadline or outcome that was never stated.
Copy a reviewed passage with its status
Keep the source link, checked original passage, reviewed translation and remaining questions together. Mark each claim as meaning checked, transcription unresolved or translation unresolved. When only one clause is checked, do not mark the entire passage complete. Label a translated quotation as a translation; reserve claims about exact original wording for words verified in the recording.
No external LLM is needed. If you optionally copy authorized text into another LLM for a draft comparison, ask it to flag possible differences rather than certify accuracy. Check every flag against the audio and both languages. This is an external step, not a Damas integration or automatic review feature.
Use video translation to choose the target text and transcription to retain the original. For individual terms, continue with the bilingual glossary. Damas gives you text to read, edit and copy before making your reviewed note.
Processing time and accuracy vary. Damas does not download media, accept file uploads, dub speech, embed subtitles or process offline. Premium cannot bypass source restrictions. If the source becomes inaccessible, unfinished checks stay unresolved. Share only within your rights.
