My best suggestion is download nVidia GeForce Experience and learn how to capture your shots using the new "Share" feature in the program. Here is a video from a year ago from someone in the UK who explains it and shows it to you. It's a good video. If you have a fairly modern nVidia card you most likely do an express installation of the driver which also installs the GeForce Experience. If you do a custom installation of your driver (I choose nVidia Driver and PhysX only), you can download GeForce Experience from the link below.

To edit a video takes practice with whatever video production software you choose. Just like this game, you have to practice over and over to learn the nuances and complexities of the software's UI and Features.
I do have a tip for users who want to dabble with http://www.fraps.com . If you're just going to upload a shot, download a free AVI to MP4 Video Converter. FRAPS* uses the raw video format .AVI. These are huge files that even for one shot are going to be over a Gigabyte in size. Just convert that file to an MP4, the most universal video file type. It will look great and only be around 200 to 400 Megabytes. Then upload it to YouTube.
*I paid for FRAPS nearly 10 years ago and updated it twice. The free/trial version does have some limitations but does work nicely on W7 and W10.
Good luck to all!
