Alternate method is to intro it as a “business record” - which would also apply in this case. The ‘custodian’ of records comes in and testifies [usually through a written declaration] as to the manner of recording, date, time, ordinary practices, etc.
Again, almost never is an issue that is seriously argued.
NOTE: Neither of these methods is to establish what should or should not be interpreted. This is how to authenticate those videos to be intro’d into evidence - only that they are what they purport to be.
