I am also new to the world of legal videography. Now I have been married to a court reporter for 27 years. I do have some exposure to the field. Something my wife has said to me about the instant hand over of an SD card for sound is cost of them. If they (court reporter)provides that one thing, many do not carry a spare. The other was she had a instant hand over from a newer videographer and the sound was choppy. It was not his recording but the backup he took it from. Claims his cable was bad. It then took a few days to get a clean copy because the video was sync'd. So that could be an issue. I tell them an upload in MP3 will be ready within 24hrs or sooner if needed. Then I get an email to send it to. I also let them know that I will remove that from the drop box or google drive within 5 days. Unless its an overnite most are OK and seems that many do not even want a copy. Several that I sat in on the reporter didnt want a copy being they have many forms of sound recording themselves. Also with small towns they seem to be more willing to use more modern equipment. The local courthouse has flat screen smart TVs. Where as the big city courthouse still has a DVD cart with a VHS player still on it. One of them is tube type TV and they roll it into the court room. Most of the time the ordering person will tell you how they want it. I have a firm that wants the raw and then does final editing. They do that even with my friend who has over years years doing this.
The only real advice I can give is to be ready to go at any time, and when your done with a recording make sure you put your stuff back ready for the next one. You never know when you may get a call to cover right after you finish.
My first job was a call to my wife to cover a depo that started at 10 am, it was 9:55. The job was not covered by another firm. The scheduler also said she was looking for a videographer. My wife asked do want me and my husband? It was a Yes. So now I have to get my suit on load my gear and then drive an hour to my first alone job. We were on the record by 11:30. So I had very little time to set up and do my testing. I didnt have to make my wife a MP3 but for practice I did. I would practice setting up your equipment and tearing it down. Another tip is walk out of the room and have someone change something like unplug a mic, or move a gain control, or unplug something. You may use your camera for a wedding with a shotgun mic and need phantom power, while your depo setup requires it. You can see where that can go. Not damaging but sometimes things get touched by accident while on a brake. Expect this more in a tight room. Doing this will help you trouble shoot if something goes wrong. Laywers do not want to sit around while you go through a check list. Be alert and professional, do not offer more than you can do. Right now I have a 3rd party doing my sync if needed. I tell my friends I have to be professional and invisible at the same time.
