The last time I gave a video clip to law enforcement it was a plain old MP4 and they had no problem with it. There was an accident in the roundabout and my MP4 was used for the police accident investigation, the attorney for the injured and for the insurance company. This is in the USA. is there something I'm missing, I admit I am a rookie at this? The case has not, and may not, go to court. A quick Google search shows the California court system wants AVI and MP4.
