Things You'll Need
Instructions
Connect your capture device to the computer and install the necessary software.
Connect the Xbox to the capture device and test it to see that it is receiving the video and audio signal. It is often helpful to connect the Xbox to both the capture device and a television as the capture device display is often delayed, making it difficult to play the game properly.
Start recording and play your game. When you have recorded the portion of the gameplay you need, stop the capture software.
Trim the beginning and end of the video using the capture software. Save it as an AVI or MOV file.
Go to a video upload site such as Youtube, create an account, if necessary, and upload it. Select the file you created, edit the title, description and other details, then save the video.
