This just in from the UK: Video analysis: codes of practice for forensic service providers.
"This appendix covers forensic digital video analysis laboratory activity from receipt of video material through to preparation for court. It does not yet include retrieval from the scene (this is expected to be added in due course) nor expand on the requirements laid out in the codes on the presentation of expert evidence. It applies to all providers undertaking this work whether they are police facilities, commercial suppliers or academia."
It's an interesting read with some controversial suggestions.
Check it out.
