As a company that works with video from many places we often hire freelance videographers to cover shooting requests from our clients. When a videographer is new to us we try to make sure that they are clear as possible regarding what we expect in order to give our clients what they deserve. This is highlighted by the instructions you see below and the video attached to them. While this is a Soccer match the principals apply to all of our sports.
TECH NOTES: At the beginning of each game please give us an audio billboard letting us know who you are shooting, when it was shot, their uniform number and colour. In all instances we prefer the footage be shot at 720P and AVCHD 25 mbps or less and with a frame rate of 59.94 fps. Also, when our client is not on the field it is not necessary for you to keep filming. It just means more footage to go through.
