I use a 4K professional video camera and a high definition professional video camera when two video cameras are needed. The video is edited with Final Cut Pro X. This is Apple’s professional video editing programme. The 4K camera saves the recording to two SanDisc extreme Pro SDXC cards. This means that in the very unlikely event that one of the discs fails there will be a back up recording.
I also use a professional drone for aerial video recording, which adds an additional perspective to your recording.
The final recording will be available on a DVD or Blu-Ray disc or as a video file. An advantage of DVDs and Blu-Ray are that they will both have a menu so that you will be able to go straight to a particular part of the recording, such as the vows, a particular speech, or a five to ten minute summary of the video.
