I have a youth football team and I have some video that I've uploaded/imported to my Surface Pro 4. I'd like to utilize the pen and mark up some of the photos/videos to show the kids what they are looking for. Is there an app that can help me do this or is there something that is on here that came preloaded that I just don't know about? Any help would be great. Not looking for NFL type stuff here. Screen shot and then draw on the photo is fine.
