METHOD 1: USING XFIRE Youtube: http://
This method uses a program called Xfire to put live video from your webcam into your game and you can from there use your preferred recording software to capture both the game and your face.
PROS: This method is very easy and free, and takes very little time to set up once it is installed and ready to go, and requires no video editing, which is great if you hate doing that. It also has other customization features and a suite of options to select from.
CONS: Using this method requires that you put your game in windowed mode to have your facecam displayed. Unfortunately, there is no way around that, but if you don't mind having to play your game in windowed mode, the only other drawback is that it may have issues activiating in game if you already have your recording program open. I had this problem specifically with Bandicam recording software. The easy fix is don't starting your recording program until you see your face in the game.
METHOD 2: USING VIDEOPAD VIDEO EDITOR Youtube: http://
This method uses yet another free program called VideoPad Video Editor. This program is similar to full fledged editing software, because it actually is one. However, for this purpose and many, many others, the free version of this program gets the job done fantastically. Best of all, there is no time or use limit on the free version, so you can enjoy editing your videos like this for as long and as much as you like.
PROS: Unlike with XFire, you can play your games in full screen however you like. This method uses video editing to merge your game footage with your facecam video, so no need to worry about lining up your face just yet. It is simple to do and use, and can potentially create higher quality videos that with XFire, if you do it correctly. You can also add some cool effects to your videos besides the facecam, and some cool borders and effects to your facecam as well.
CONS: There aren't many complaints with this method, the only few that there are is that some have trouble lining up their facecam with their gameplay, but that just takes time and practice to figure out. It can also be a pain to start recording your face then go back into the game to record that and have to get the perfect starting point found out. The only actual con with the program is the video render time. The render time with this software has been significantly longer than Windows Live Movie Maker for me when rendering a video with that, but this software has more features, like facecam capabilities, so it's a fair tradeoff, especially at the price of free.
CONCLUSION: If you're an up-and-coming YouTuber looking for a simple way to create interesting gaming videos, I have created this guide just for you. Be it with Xfire or VideoPad, you're going to get good results fit for any successful YouTube channel. Thanks for reading, and enjoy gaming!
