Q3. What makes a video clip be regarded as being "interfered" and that may cause it inadmissible in court?
Any editing or post-production on a video clip would render the clip being “interfered” or “tampered” with and thus adversely affect or even completely destroy its authenticity. This is also the reason why only original of a video clip will be admissible because a copy is always subject to the accusation that it could have been “interfered” or “tempered” with.
For the same reason, if the authenticity of a video clip is being challenged, the person who took the clip should be ready to confirm to the Court that he/she has all along kept the video clip in his/her safe custody without any possible interference of the clip by any other person.
