B) Only a portion of a recording is analyzed by additional or corroborating information that appears in earlier parts of the recording.
C) The original is secured as evidence and stored where it will not be damaged by magnetic fields, heat, or humidity.
D) The digital video is in a proprietary compressed format and the software was not obtained to view the file.
