There are 2 ways.
The first way is to use a capture device (capture card).
The second way is to upload the videos to your file share and render them with render points. They can then be downloaded to your computer from their URL on bungie.net
You have to subscribe (pay) to Bungie Pro. Once you do, you can render your videos and download them.
They usually use hd capture cards and send it to the computer
You have go to theater and record your videos put them into some type of tape and mail it with the mail truck to Rooster Teeth with a letter asking them to play your video.
use your webcam or camera, then upload it to your computer. another way is that if your xbox is near your computer hook it up to a capture card, try searching youtube about that. If it helped, recommend me! -P
