Noob with video question

Trying to help my son get his recorded video off his flash drive. Skyrim game play appears in Horizon but not Halo video that he saved to the drive.

Anyone know why?

He wants to make a video from halo gameplay. I can teach him video editing. Getting the video file however, is somewhat more challenging.


Can you provide some more information on the equipment that is being used to capture the footage and also any software.

u go to movie maker and edit your narriation sound effects and image to beter quality
