It really depends significantly on the court and what the court might make as a ruling and the Judge. However, the more time in advance that you can provide that to both the opposing side and ideally the court, the better. Sometimes you can do such a thing as emailing it both to a clerk from the court but you want to check that ahead of time and making sure that you send that to the other side as well. 

A lot of judges will take both the email but prefer a thumb drive to be provided as well and depending on if it is an Evidentiary Hearing and if it is ahead of time, having that is sometimes as listed as one of the exhibits and is provided with your exhibit book.  Other times; particularly if there are emergencies or not much notice, the parties are able to use the phone or the video recording at cross examination or it is part of the hearing itself.  Again, a better practice is to provide that to the other side ahead of time and to find out the best ways to do so.  It is important to be able to figure out the best way that you can get this evidence before the court.  Sometimes there are restrictions and it is good to either have your lawyer figure that out ahead of time or if you are representing yourself; speaking to someone from the court about the best way to get that in front of the court.
