An Ontario Private Investigator captures video footage of a subject engaged in activities contrary to their insurance claim. For this evidence to be admissible in court, what is paramount regarding its handling?

1. Deleting any uneventful portions of the video to save storage space.
2. Maintaining a strict chain of custody, ensuring the video's integrity and authenticity are preserved from capture to presentation.
3. Sending the raw footage directly to the client via email.
4. Editing the footage to highlight incriminating segments.
