Keep original audio and video files untouched, document where each file came from, and create a working index with date, source, people, language, duration, and the exact timecodes that matter. A transcript or translation should point back to the original media.
Why this matters
A strong evidence file is not just a large collection of documents. It should help a reviewer understand what happened, when it happened, where the information came from, and what fact each item supports. Organizing the record before an interview, hearing, or attorney meeting also makes it easier to spot missing records, conflicting dates, and questions that need professional review.
What to gather
- Original audio, video, and voicemail files where available.
- Message threads, call logs, emails, or social posts that show how the file was received or created.
- Device or file metadata that remains available.
- Names of speakers and people who can authenticate or explain the recording.
- A transcript for important speech, with timecodes.
- A translation and translation certification where required for non-English material.
A practical way to organize it
- Do not convert the only original file. Preserve it first, then make working copies.
- Create a media index: file name, original source, date, duration, language, speakers, and fact supported.
- For long files, identify exact time ranges instead of telling a reviewer to watch hours of material.
- Create a transcript that includes timecodes and marks unclear words honestly.
- Keep the original-language transcript and English translation together when both exist.
- Store large media files separately from PDFs but link them through the evidence index.
Common mistakes to avoid
- Sending only a compressed clip with no original.
- Editing out surrounding context without preserving the full recording.
- Treating an AI-generated transcript as automatically accurate without review.
- Failing to identify who recorded or sent the file.
Build an attorney-review copy
Keep your permanent originals separate from the copy you use for review. A working attorney packet can include:
- a one-page factual summary;
- a chronological timeline;
- an evidence index;
- the most important supporting records;
- a missing-evidence list;
- a list of uncertain dates or possible inconsistencies; and
- questions you want legal counsel to address.
