True.  FYI, the VideoInsight system does support watermarking.  From the
manual:

Enable Watermark: To ensure that video files have not been tampered, you
can enable a Watermark to be applied to the video. Once enabled, a
unique checksum is hidden on the file and upon reprocessing, will not
match the original number if the file has been altered. Please note that
this requires additional processing time at the end of each file and may
not be necessary for every user.
